What’s the deal with Autism Spectrum Disorder (ASD)?

To begin the discussion about what ASD is, it is first important to discuss what the disorder all entails. Unlike many of the neurological disorders or conditions we have discussed this semester, ASD is outlined more by the symptoms and the characteristics of the disorder rather than by the specific brain region or pathway that has been misregulated. These symptoms include but aren’t limited to: problems with social communication and interaction, motor skills, perceptive thinking, and restricted or repetitive behaviors or interests. It is important to note that some people without ASD may also display these symptoms, but for people with ASD, these symptoms can add new challenges to life. Because ASD is inherently a spectrum disorder, there is a wide range in the severity of symptoms and thus there is a wide range of individual challenges faced by those diagnosed with ASD.

ASD Spectrum Misconceptions

The use of the word “spectrum” is inherently misleading when used to describe any kind of disorder. Classically “spectrum” is used to describe a range that includes everyone, from no present symptoms to all possible symptoms. However, in the case of ASD, the spectrum only applies to those that have been diagnosed with ASD, where then the spectrum is used to characterize the severity of an individual’s symptoms. In Figure 2 above, there is a comparison to show the different kind of spectrums used to classify ASD. The left diagram is the classic linear spectrum that many people think of when they hear “spectrum,” however, this spectrum is used to classify the severity of an individual’s symptoms and the associated level of care. Whereas, the diagram on the right is a diagram used to classify the severity of an individual’s specify autistic symptoms.

Treatments for Adults With High-Functioning Autism

Figure 3: A brief cartoon showing an overview of the available treatments for ASD.

What treatments are there for ASD?

Discussing the treatments for ASD, brings up an interesting question: Is there something wrong with those that have ASD? Speaking generally, this is more of an ethical question rather than a medical one, however, it is interesting to note that is a study of over half a million people, people working in a science or engineering job were more likely to display autistic traits than their nontechnical jobbed counterparts. So perhaps it is a good thing? There again, this is tricky to say  because in more sever cases there is something wrong neurologically. As discussed in class, there are multiple ways in which disruptions in the PI3K-Akt/mTOR signaling pathway that can develop into autistic-like behaviors. These disruptions lead to: serotonergic degeneration, translation dysregulation, decreased neuronal autophagy, neuroinflammation, apoptosis, and increased oxidative stress. So there are some autistic behaviors that can be caused my misregulated pathways, which is more serious.

However, despite the potential severity of a misregulated pathway, there are no real medial treatments for ASD. The treatments largely rely on Applied Behavioral Analysis (ABA) treatments. These ABA treatments look at how behavior works, how it is effected by the environment, and how learning works. This approach then uses this information to help a patient realize what behavior is appropriate using the ABC’s of ABA. “A” standing for antecedent is a stimulus that occurs right before a target behavior, which then results in the “B” for behavior. The important part comes from the “C” meaning consequence. To help patients, positive reinforcement is used when the behavior displayed is appropriate for the antecedent, whereas there is no reaction for inappropriate behavior.

What does this mean for the future of ASD?

To conclude, ASD is a disorder that is commonly diagnosed by its symptoms rather than by a specific neuronal irregularity. Because of this, there is no specific treatment for possible misregulations in the PI3K-Akt/mTOR pathway, but rather the treatments include things like ABA treatment that is targeted at correcting the symptoms in a patient with ASD. Despite this, there may be a future in drug treatments as shown by Figure 4 above. However, by dispelling some of the misconceptions about ASD, there opens new avenues for children diagnosed with ASD to be better integrated into schools and social settings, despite their impaired social interactions.

(A)lleviate (S)ymptoms after (D)iagnosis

Autism Spectrum Disorder (ASD) impacts every person differently. Currently there are no set treatments for ASD known to cure the disorder, however there are interventions that have been explored that may manage symptoms. These therapies aim to allow the individual to be more independent and able to partake in tasks with daily living skills, social interaction, and allowing the person to be involved and engaged in the community. Given many of these tasks are often learned from a very young age, most treatments (but not all), are implemented in children with ASD.

ASD treatments can be broken down into four different types: Behavioral/ Communication, Dietary, Medication, and Complementary and Alternative Medicine.

Behavioral and Communication Approaches

The most common behavioral approach is Applied Behavior Analysis (ABA), which is known for encouraging positive behaviors while discouraging negative ones in hopes to improve skills. There are many different categories of ABA, some of which include occupational therapy, which aims to help individuals becomes as independent as possible through guidance in learning tasks such as eating, bathing, dressing, and improving social interaction. “Floortime” is particularly used for children and it focuses on emotional and relational development through connections with caregivers. It works with a child’s coping with sights, sounds, and smells. Assistive technology helps by using technology devices like electronic tablets or communication boards to help those with ASD communicate and interact with others.

Dietary Approaches

Dietary approaches may be helpful in managing ASD symptoms. The approach may include checking for mineral or vitamin deficiencies, removing certain foods from a child’s diet, and supplementing for any deficiencies. This phenomenon is thought to be the outcome of food allergies or lack of vitamins and minerals that result in ASD symptoms. Likewise, diets may contribute to the improvement of ASD therapy via modulation of PTEN/AKT and GSK3B signaling. Diets that involve PI3K/ AKT pathways could result in neuroprotective effects. The nutrients in food can either activate or inhibit the PI3K/ AKT and GSKB pathway. Specifically, curcumin inhibits PI3K, as shown in Figure One, which is overactive and highly dysregulated in autism, which suggests it’s use as a modulator for therapy in ASD.

Figure One: 

 

Medication

While there are no medications known to “cure” ASD, some medications may lessen symptoms or improve functioning. Some examples are medicines that manage energy levels, focus abnormalities, anxiety, depression, behavioral reactivity, and seizures.

Complementary and Alternative Approaches

Complementary and alternative medicine treatments (CAM) are often used in addition to or instead of traditional treatments and can often be quite helpful at managing symptoms. They include but are not limited to mind-body medicine, special diets, dietary supplements, chelation (removing heavy metals like lead from the body), or biologicals like secretin. Additionally, craniofacial and dental professionals may help to meet the oral healthcare needs of those with ASD.

Overall, while there may be no cure for ASD, yet, the treatments and therapies available all have a common goal to improve the daily life of those with ASD, by helping them to become more independent and capable of navigating the day to day events that occur.

Anxiety- Survival Mechanism Gone Wrong

Anxiety through history

The term anxiety has an ever changing image, and as time rolls on so does our opinion and understanding of the term. Originally anxiety was a survival mechanism, activated by times of stress. These were usually life or death situations in which the stress and anxiety were pivotal in development of knowledge and skills which would help survival. As humans advanced in technology and development so did our stressful situations. We began to see people affected very poorly by traumatic events such as war. While PTSD was acknowledged there was a stigma around the word anxiety. Before science had information about the disorder it was viewed as a weakness. Now there is proof of its physiologic effects on the body and more specifically, the brain. Today anxiety disorder impacts an estimated 40 million people in the United States alone. This is due to the double edged sword of more awareness and knowledge. 

Stress V Anxiety

Stress vs. anxiety: Differences, symptoms, and relief

While anxiety is a common feeling in times of stress we are beginning to see a rapid increase in disorders related to anxiety. Anxiety disorder is a much more serious condition that is linked to a plethora of changes in neural physiology. Anxiety disorder symptoms consist of a constant feeling of stress, lacking concentration, irrational fear, and many other debilitating symptoms. 

Anxiety disorder can be treated in many different ways depending on the severity of the disorder. In absence of medications a healthy lifestyle is very important. Eating healthy, getting exercise, and enough sleep can help prevent the development of long term anxiety and helps with symptom relief. Certain therapies and counseling are also very beneficial for many people who are experiencing anxiety. For more severe cases there are different pharmaceutical remedies available for prescription. Certain antidepressants like selective serotonin reuptake inhibitors (SSRIs) can be used. However, the most common anxiolytics are benzodiazepines which suppress the overactive chemical signaling in the brain. 

Similar diseases to anxiety show a very similar pathology. PTSD for example shows a similar origin to memory modification during times of stress or anxiety. A dysfunction of the survival mechanism used to remember stressful times and solutions has led to a prolonged memory of stressful times. Glutamate release in times of stress leads to an activation of the MAPK pathway which eventually causes gene transcription. This makes a consolidation of event associated memories. 

In summary anxiety is a normal bodily function which causes transcription events that increase memory in times of stress. This normally healthy process is being disrupted in anxiety disorder and other stress related diseases. There are natural ways to reduce the risk of these developing and treatment options available to help regulate the chemical signaling in the brain. What was once was a survival technique is now a serious health issue plaguing millions in the united states alone. 

Anxiety vs. Anxiety Disorders

Anxiety is something we have all experienced on multiple occasions in our lifetime. The first time I remember feeling anxious was when I was three years old. I was onstage in a pink tutu, my hair was in a slicked-back bun, and I had leather ballet shoes on my feet. It was my first dance recital. I included an image to the left so you can picture three-year-old me.

3-year old Hannah.
An image of three-year-old Hannah in the costume I wore during my first dance recital. Photograph was taken by Reeves Photography in Grand Forks, ND (2004).

At that time, I was just starting my dance career, and I had never been on the stage before. I remember the lights were shining on me so brightly, and I knew my family (along with dozens of other people) were watching me. I was so nervous to perform in front of all of those people, and I decided that the best way to get out of that situation was to run offstage, tears falling down my face as I did so. My dance teacher at the time (bless his heart) talked to me and calmed me down from my panic before convincing me to go back onto the stage. I followed his advice, and I proceeded to take the stage that night and for fifteen years following that event. The anxiety I felt before going onstage never really went away, but it became a normal part of my life and became more manageable. This is a specific instance, but I have had many experiences with the feelings of anxiety—worry or unease about a specific event or condition.[1] In addition, I have been surrounded by anxiety disorders my entire life (even if I wasn’t aware of what it was at the time).

Anxiety disorders run in my family. I can think of multiple family members that have some sort of anxiety disorder, whether they admit it or not. Generalized anxiety, post-traumatic stress disorder, separation anxiety, and obsessive-compulsive tendencies are all anxiety disorders I have witnessed in my family. Anxiety disorders, however, are different from anxiety. Yes, they tend to share similar physical symptoms, but there are nuances that separate anxiety from anxiety disorders. As I previously stated, anxiety is the feeling of fear or unease concerning a specific event or condition. Physical symptoms of anxiety include elevated heart rate, sweating, having difficulty breathing, and nausea. Though anxiety disorders have these physical symptoms, as well, it is the effect the anxiety has on one’s life that makes it different from anxiety. Anxiety, because it is triggered by an event, has an anticipated end. If you are anxious about an exam you have, the anxiety will likely go away after you finish that exam. Anxiety disorders, on the other hand, are unpredictable—both in duration and triggers. The feeling of uneasiness can last twenty minutes, or it can last for three hours. The triggers can also be unpredictable. A family member I have that has PTSD is triggered anytime she sees rapids in a river, but my anxiety (GAD) is not necessarily triggered by anything. Anxiety disorders are unpredictable, but they are primarily characterized by feelings of anxiety and panic that are out of control, not appropriate for the situation, and interfere with daily activities.[2] More differences are outlined in the picture below.

Many people in today’s society think the term “anxiety” is synonymous with anxiety disorders. The incorrect terminology has been perpetuated through media and has had a generalization effect on anxiety disorders. Many people are guilty of generalizing anxiety disorders (I’m on the proverbial soapbox, but I have also been guilty of doing this), but this generalization makes it hard for anyone with diagnosed with an anxiety disorder to be taken seriously and feel understood. A common response to being startled is “you gave me a panic attack.” This statement invalidates people with panic disorder because now a panic attack is nothing more than a simple fright. Some individuals clean and straighten things up because “my OCD is bothering me.” This statement is invalidating to people with obsessive-compulsive disorder because OCD is now associated only with cleanliness and order—it disregards the two main characteristics of this disorder: obsessive thoughts and overwhelming compulsions.

The main point of this post is not to shame anyone or call anyone out (though I realize now that it seems like it). I just think it is important to spread awareness about the differences between anxiety and anxiety disorders. There are significant differences between anxiety disorders and the feeling of anxiety, and I think not a lot of people are aware of these differences. I think it is important to shed light on the generalization of anxiety disorders and how these generalizations can be hurtful.

Understanding anxiety

Hippocampus is crucial for memory consolidation, from working memory to long-term memory. The subregions loop through dentate gyrus and CA3 and CA1 areas,.

Cortisol is released by the adrenal glands and is involved in glucose metabolism, blood pressure regulation, inflammatory responses among many others.

Cortisol is necessary when it comes to the fight-or-flight mechanisms, by causing faster breathing, heart rate in case of a stressful event. This is important in small quantity, due to anxiety behaviors caused by elevated cortisol levels in the body. It can potentially be caused by eating disorders, lack of exercise hence making it necessary to practice meditation, exercising, eating nutrient-rich foods.

Along with Cortisol, adrenal glands also secrete glucocorticoid in the hypothalamus, which similarly produces stress response and coping.

The exposure is largely caused by negative events affecting the brain. This could go even beyond into  . There are three major ways that may lead to the occurrence of a trauma/ anxiety behavior. The event,the experience of the event, and the effctts of the event.

Anxiety

Most people know what it feels like to be stressed or anxious about something. Whether that be a small scenario like taking an exam or having it be a larger scenario like the death of a loved one we have all had the same type of feeling. It is common for people to experience these kinds of stress and it is even more common for people to want it to go away and ignore it completely. This may be because you are afraid of failing at a specific task. 

However, it has been tested that stress can actually help you when you are in danger. This was done using the forced swim test on rodent rats. According to a research study, the rats would be put in a container twice at different times and the container would be filled with water to prevent the rats from escaping [1]. The first swim test showed the rats trying to escape for a longer duration than the second time they were put in the water. Meaning that from what the rats learned from their previous encounter, escape was not an option and that conserving energy by being immobile, floating, in the container was the best option for survival [1]. This shows that the rats adapted and learned a behavioral immobility response from the previous experience with the water container.

This type of learned behavior can be viewed as a way of bringing up bad memories of a previous event that has some association with the present event you are in. Most people don’t know what goes on in your body when experiencing that type of stressful situation. The psychological stress you experience indirectly leads to the consolidation of memories thanks to the signaling pathways and epigenetics involved [1]. Specifically, the release of glutamate and corticosterone are caused by the stress, which leads to the binding of glucocorticoid receptors and ERK signals [1]. This leads to a form of epigenetics that causes histone acetylation, which means that the chromatin in your DNA becomes less compacted and increased amounts of gene transcription occur for the genes responsible for the consolidation of the event-associated memories [1]. This shows that learned behavior is not only caused by environmental factors but genetic factors as well when dealing with stress. 

While stress can be viewed as a way of helping somebody get out of a dangerous situation, it has however been linked to some brain disorders, such as PTSD. Post-traumatic stress disorder develops after extremely stressful, frightening, or traumatic experiences such as abuse, serious accidents, conflict, and especially military services [2]. This can be linked to how stress factors lead to the genetic transcription of genes that function in consolidating related memories since PTSD is also involved in reminding the person of the traumatic event based off of a stimulus. This is also evident on the feature image as well showing that a traumatic event can be linked to multiple types of disorders. 

This shows that once in a while it is considered to be okay to experience stress as it can pertain to helping you out of either a dangerous or uncomfortable situation. But too much stress can lead to mentally harmful disorders that can affect your life.

Animal Models for Anxiety

Anxiety can be characterized by many different symptoms an individual my experience. From nervousness when talking in front of a large crowed to test taking, these stressful situations can significantly increase and interfere with daily activities. When this occurs, individuals may experience excessive worry, emotional distress, and severe anxiety. Such symptoms are diagnosed as generalized anxiety disorder. In the United States, 40 million adults experience some form of anxiety disorder, most starting before they even turn 21 years old. 

 

 

 

 

Figure 1.

This number doesn’t specifically refer to the generalized anxiety disorder prevalence, but it does provide an overview of the commonality of anxiety disorders. That being said, there are many types of anxiety that individuals may experience, from generalized anxiety disorder, panic disorder, social anxiety, and specific phobia. Theses are the top leading types of anxiety experienced by people today.

In order to come up with these diagnoses scientists must perform studies an animal models in order to find a baseline for symptoms of anxiety. One way researchers can do this is by conducting a Morris water maze test. Morris water maze test is a conduct strategy generally utilized with rodents. It is generally utilized to conduct spatial learning and memory. It empowers learning, memory, and spatial attempting to concentrate with extraordinary exactness, and can likewise be utilized to survey harm to specific cortical areas of the cerebrum. It is utilized by neuroscientists to quantify the impact of neurocognitive problems on spatial learning and conceivable neural medicines, to test the impact of sores to the mind in territories worried about memory, and to concentrate on how age impacts intellectual capacity and spatial learning. The errand is additionally utilized as an apparatus to consider drug misuse, neural frameworks, synapses, and mental health. 

Figure 2.

There are three phrases used to test the Morris water maze: 

Training phase-    

Escape latency is how much time it takes to find the platform  

Wall hugging can measure the rat not learning or anxiety  

Swim speed can measure how drugs change swim speed and how long it takes to find the platform  

Swim pattern shows the search strategy  

Probe trial-   

Time in target-the removal of the platform can see if the rat is using a strategy to find the general area of the platform when it doesn’t know where it is vs. the rat knowing where it is using a special strategy  

Quadrant-   

Tracks how much time the rat spends on the platform 

The Morris water maze test is one of the most regularly utilized conduct tests to quantify spatial learning in rodents, including rodents and ordinary and hereditarily adjusted mice. It was first evolved and revealed by Richard G. Morris to test the spatial learning conduct of rats. He demonstrated that a hippocampal injury would weaken spatial learning. The test device comprises of a roundabout water tank filled with hazy water and a shrouded stage submerged a couple of centimeters under the water surface in one quadrant of the tank. The tank is encircled by viewable signals. Preparing the creatures to find the concealed stage may take a couple of days (normally 5–7 days). In each preparation preliminary, the test creature is permitted to swim in the water for 5 minutes to locate the shrouded stage. On the off chance that the creature doesn’t discover the stage within the 5-minute time frame, it is safeguarded and set on the stage. Every creature at that point goes through 5 minutes on the stage before being gotten back to its home cage. Every creature has five instructional courses a day. Given that the stage is covered up, the creature must figure out how to utilize the viewable signals encompassing the pool to find the stage. As preparation advances, the time used to locate the shrouded stage will ordinarily diminish. Such diminished break latencies will most regularly mirror the reception of a central inquiry methodology for creatures with no disability in spatial learning. Notwithstanding decreased getaway latencies may likewise mirror the selection of non-spatial methodologies (e.g., mice may figure out how to swim in concentric circles a fixed good way from the divider). In this manner, to separate spatial and non-spatial systems, mice are normally given a test, where the stage is eliminated from the pool, and the mouse is permitted to look for it, commonly over a 60-second time span. Mice having received a spatial procedure will center their pursuit close to the previous area of the stage.

 

Anxiety-induced memory formation and current research

Introduction:

Anxiety can be characterized by feelings of nervousness, fear, and stress. Having some anxiety in everyday life is normal and can be positive, but when these feelings interfere with typical daily activities is when this can be an issue. Anxiety disorders occur in 18.1% of the United States population, which is why doing research to improve the lives of many Americans is essential. Depending on the history of someone battling with anxiety, anxiety disorders can be characterized in many ways. In general, most people with anxiety have overactive brain stimulation due to inappropriate glutamate/GABA control. Glutamate activates neurons, while GABA inhibits neurons. Thus, the neurons either are being stimulated by too much glutamate or that there is not enough GABA in the brain.

Who is at risk for anxiety?

Many factors contribute to the likelihood of developing an anxiety disorder. People who have anxious tendencies are at risk for anxiety, as well as people who have experienced past traumatic events. Traumatic events can include sexual assault, combat, natural disasters, serious injuries, and etc. However, trauma is processed by every person differently, which is why some people who have experienced trauma have anxiety disorders.

Brain structures:

Many brain structures can be impacted in anxiety disorders, such as the dentate gyrus, supra-mammillary area, and amygdala. The dentate gyrus can be considered a part of the hippocampus. The hippocampus is responsible for learning and memory, while the dentate gyrus is specifically responsible for episodic memory. Episodic memory is the ability to remember and almost re-live events from someone’s past experiences.

Episodic memory and stress:

Stress can increase glucocorticoids. Glucocorticoids can help to form stronger memories in the hippocampus, specifically the dentate gyrus by upregulating the NMDA/ERK pathway, which is responsible for memory formation.

NMDA/ERK pathway:

Figure 1: AMPA/NMDA/ERK pathway with glucocorticoids by Lauryn Hinckley.

AMPA and NMDA are receptors on neurons that bind glutamate to “excite the cell.” In Figure 1, AMPA receptors can open when glutamate binds to depolarize the cell and can help NMDA receptors opening by depolarizing the membrane. Once NMDA binds two glutamate neurotransmitters and removes the magnesium block, this receptor allows sodium and calcium to enter the cell. Calcium activates CamKII and RasGrfs, which both ultimately activate Ras, a kinase upstream of MAPK/ERK.

Ras phosphorylates Raf, which phosphorylates MEK, which phosphorylates MAPK/ERK. When stressed, the body also releases the hormone glucocorticoids, which can bind to a scaffolding protein and increase the activation of MAPK/ERK. The activation of this pathway increases the activation of Elk-1 and MSK, which both function to increase memory formation and consolidation in the dentate gyrus. Also, the combination of MAPK/ERK bound to glucocorticoids increases the likelihood of epigenetic changes on histone 3 in the DNA from stress, which include phosphorylating serine 10 and acetylating lysine 14 in the dentate gyrus. This modification can increase the expression of intermediate early genes (IEG).

 

Intermediate early genes:

IEGs induce the transcription of c-Fos and Erg-1 to increase and strengthen memory formation. Overexpressing IEGs from experiencing prolonged stress can increase the likelihood of having anxiety due to increasing the amount of stressful memories and making these memories more vivid. However, exciting research in some antidepressants can decrease histone modifications from stressful events as seen in mice studies.

GABA:

Also, another exciting direction in research is looking at GABA in anxiety. Having too little GABA can reduce the neuron’s ability to “quiet down” to avoid vivid and recurring stressful memories that cause distress. In order to increase GABAergic control, some researchers have found that exercise increases the expression of GAD (GABA synthesizing enzyme) after long-term exercise in rats. In rats, the researchers also found that there was reduced activation of the MAPK/ERK pathway that increases the expression of IEGs, thus reducing anxiety symptoms.

So now what?

Research has shown that various medications and even exercise can decrease the expression of IEGs to reduce stressful memory formation and consultation in order to better alleviate symptoms of anxiety disorders. More research needs to be done in order to better treat those with anxiety disorders to return to typical daily activities to improve their quality of life.

The Perfect Housewives of the 1950s: Poodle Skirts and Debilitating Drug Addiction

The 1950s housewife of choice

Extremely productive, beautiful, and skinny, getting all their chores done in one simply day, just to then start over the next morning. In the times when there was no sign of dishwashers, washers and dryers, microwaves, instant ramen for lunch, or easy to use Swiffer Sweepers at all in a regular middle-class household. The perfect women would still get all the work done around the house, take care of about 4-6 children, cook food for the whole family (with a dessert – daily), great their husbands nicely dressed and with a smile at the end of the day, then have a long night of sleep. All this, in the midst of the Cold War. Anything seems off? Well, it should, as explained by the perfect recipe of a ‘50s housewife: daily amphetamines and barbiturates.

 

 

“Mother’s Little Helpers”

Ah, the little pills to treat the pressure of womanhood. Back in the days potent pharmaceuticals were thought to be a woman’s best friend, helping them through all that came with the societal expectation of a perfect wife and mother. For those wishing to lose weight and be happier housewives, amphetamines were readily available. Along with general everyday tasks of life and prescriptions of all kinds of amphetamines came the “trendy anxiety”, treated by Valium, Librium, or the most popular of all: Miltown. Amphetamines, barbiturates, benzodiazepines, all of which were included in “mother’s little helpers”. Doctors would even prescribe a drug called Dexamyl, which was a blend of amphetamine and barbiturate sedative amobarbital (read more about drugs prescribed during these times).

The long days of getting exhausting chores done were assisted by glamorized amphetamines, then the stress along with war-anxiety was easily cured by heavy tranquilizers. Productive during the day, stress free and deeply sleeping at night, what could be the problem?

Heart Medications for Anxiety?

Propranolol - Wikipedia

Figure 1: The chemical structure of propranolol.

The use of propranolol

The most commonly prescribed medications typically tend to be those that target immediate health issues such as pain or heart problems. Propranolol is one such medication that is common prescribed for hypertension, coronary artery disease and tachyarrhythmias. However, this medication can readily enter through the blood brain barrier, so there uses can be much more then simply an heart medication.

How Pathogens Penetrate the Blood-Brain Barrier

Figure 2: Diagram of the blood brain barrier.

Mechanism of action

As seen in Figure 2 above, the blood brain barrier can be pretty tricky to cross. So, those medications that can offer a cascade of treatment possibilities. In the case of propranolol, it is a β 1,2-adrenoreceptor antagonist which will compete at the receptor level with catecholamines, thus blocking their effect. This mechanism has also been deployed to block β1,2-adrenoreceptors in the central nervous system. So, it is through the blocking of the catecholamines (adrenaline, noradrenaline, and dopamine) from binding to their corresponding adrenoreceptors that propranolol is able to reduce anxiety.

Figure 3: Commonly used SSRIs used in treatment of anxiety and depression

Why isn’t propranolol prescribed for anxiety?

While the use of propranolol offers many promising results in both animal models and its use in humans, the world of treatment went a different route in the treatment of anxiety. The more recent prevalence of selective serotonin reuptake inhibitors (SSRIs) took the scene before propranolol could be effectively implemented for the treatment of anxiety. SSRIs, as the name implies, act to block the reuptake of serotonin in the synaptic cleft after it has been released. The presence of serotonin in the synaptic cleft has been proven to be an effective treatment for an assortment of disorders, but I’m mainly focusing on anxiety. So, it isn’t so much that propranolol isn’t used because it isn’t effective, but rather because there are more popular substitutes instead.

Memory Consolidation | Overview, Facts, Information, Definition

Figure 4: Generalized pathway for how stimuli is converted into long-term memories.

Function relating to memory

For the article we discussed in class, we mostly looked at how anxiety and stressful situations contribute to memory. This was seen with the use of the forced swim test as the stressful situation led to an increase in memory of the test as well as a corresponding change in behavior (reduced time to begin the immobile phase of the forced swim test). To continue with the idea of anxiety and memory, propranolol actually has an effect on this too!

As seen in Figure 4 above, there is a consolidation step that occurs after short-term memory that helps to convert sensory stimuli into long-term storage. This typically involves protein synthesis. Propranolol acts by selectively inhibiting this protein synthesis of fear inducing stimuli so that the fear memory is unable to be reconsolidated and converted into a long-term memory. It is believed that the selectivity acts by inhibing the feeling of fear in the memory, but leaving the overall memory of the stimulus otherwise unchanged.

The use of propranolol

As discussed above, propranolol is a commonly prescribed heart medication that also has to ability to help treat anxiety disorders, quite effectively. However, because of SSRIs shared ability to cross the blood brain barrier and the increased popularity of SSRIs, propranolol has been reduced to being prescribed for heart problems. But who knows, maybe in those that do have it prescribed, it is doing wonders!

For more information about propranolol, please see the following article here.
