Is Anxiety A Neurological Disorder

The Neurological Basis Of Anxiety

A person suffering from an anxiety disorder experiences neurology-based changes in mood and bodily functions that are discussed in more detail in this article.

As with anxiety, various personality traits and emotional responses are by-products of the interaction between our genetic coding and environmental influences. Our genes make us more receptive to some specific stimuli and play a role in developing the resilience to some other stimuli. Our brain is a plastic organ. Thus, the role of environmental factors in its development and casting cannot be negated.

Fear and stress are normal defensive reactions to threats that help our body to deal with challenges more efficiently. Anxiety is different from fear in that it is a set of emotional and somatic reactions to a future threat that may or may not be realistic. To some extent, having anxiety is a normal human reaction. However, if it continues for a prolonged period, it may have an adverse effect on our daily life and health.

In the state of anxiety, worrying about the future makes it difficult to concentrate and leads to irritability. Somatic symptoms like palpation, sweating, and gastrointestinal changes are also common in this state. Anxiety is considered as a disorder if such symptoms persist over a period of six or more months.

Is Depression A Neurological Disorder

Certain areas of the brain regulate mood, but which areas are involved is not completely understood. Areas that play a role in depression are the amygdala, the thalamus, and the hippocampus. Some research indicated that the hippocampus is smaller in depressed people. Stress may also play a part as it can suppress the production of new neurons in the hippocampus. The mood may only improve as nerves grow and form new connections. Depression is a mood disorder, but when Parkinsons disease occurs, depression is part of the disease as it changes areas of the brain that produce chemicals that involve unregulated mood, energy, motivation, and sleep.

Recent research has indicated that there is a neural basis for the onset and progression of depression, although the literature on this theory is still lacking. Psychiatric and neurologic depression appear to share common abnormalities in common brain areas.

Is Anxiety A Neurological Disorder

Anxiety is a normal human emotion, but excessive anxiety is different. The exact cause of anxiety disorder is not known, but they do tend to occur frequently in those who have neurologic disorders. Generalized anxiety disorder probably arises from excessive activation of the brain mechanism involved in fear and fight-or-flight response. Over time, anxiety can become attached to thoughts, memories, and situations unrelated to the source of danger. In other words, the brain creates its fears.

A variety of factors appear to influence anxiety disorder and could include chemical imbalances in the body, especially in the brain, which controls mood. Anxiety also runs in families, while environmental factors such as trauma or a significant event may also trigger it.

Possible Causes Of Medically Unexplained Symptoms

Many people with medically unexplained symptoms, such as tiredness, pain and heart palpitations, also have depression or anxiety.

Treating an associated psychological problem can often relieve the physical symptoms.

For others, the symptoms may be part of a poorly understood syndrome, such as:

• irritable bowel syndrome
• fibromyalgia

The fact that doctors are unable to find a condition causing these symptoms isn’t unusual in medicine, and it doesn’t mean that nothing can be done to help you.

Increase In Major Depressive Disorder And Anxiety Due To Covid

Subjects Neurological behavior disorders

HealthDay News An overview published online in The Lancet on October 8th has estimated an additional 53.2 million cases of major depressive disorder and 76.2 million cases of anxiety disorders worldwide due to the COVID-19 pandemic.

Damian F. Santomauro, Ph.D., of the University of Queensland at Herston, Australia and colleagues conducted a systematic review of data reporting the prevalence of major depressive disorder and anxiety disorders during the COVID-19 pandemic. The collected data were used in the meta-regression to estimate the change in prevalence between prepandemic and mid-pandemic periods. Forty-eight unique data sources met the inclusion criteria.

The researchers found associations for two COVID-19 impact indicators, in particular the daily infection rates of the severe acute respiratory syndrome Coronavirus 2 and the reduction in human mobility with an increased prevalence of major depressive disorders . , 18.1 and 0.9, respectively) and anxiety disorders . Compared to men, women were more affected by the pandemic, younger age groups were more affected than older age groups. The sharpest increases in the prevalence of major depression and anxiety disorders were estimated in the locations hardest hit by the 2020 pandemic. Another 53.2 million cases of major depression and another 76.2 million cases of anxiety disorders were estimated worldwide due to the COVID-19 pandemic.

What Is Functional Neurologic Disorder

Functional neurologic disorder , also called conversion disorder and functional neurologic symptom disorder, refers to a group of common neurological movement disorders caused by an abnormality in how the brain functions. FND is not caused by another disorder and there is no significant structural damage in the brain. The exact cause of FND is unknown. FND was thought to be a conversion disorder by Sigmund Freud because he believed it was a psychological disorder that converted into a neurological one.

Someone with FND can function normally, they just cant at that moment. Their brain is unable to send and receive signals properly and there is a disconnection in the function of the lobes and emotional processing. Memory, concentration, cognition, and the processing of sensations also can be affected.

FND causes real symptoms that significantly interfere with how you function and cope with daily life. If you have FND, your unplanned movements and symptoms occur without you consciously starting them and are inconsistent and distinct from symptoms that are intentionally produced. FND can involve any part of your body. Symptoms may appear suddenly, increase with attention to them, and decrease when you are distracted.

FND can be difficult for you, your family, and doctors to understand. Early diagnosis and treatment can help lessen symptoms and aid in healing. .

What Are Psychiatric Disorders

Psychiatric disorders are typically associated with disturbed behavior and a patients emotional state. Treatment for these types of disorders falls under the purview of a psychiatrist, psychologist, or licensed therapist.

These types of disorders occur for a variety of reasons. The list of potential causes of psychiatric disorders includes:

• Trauma
• Genetics
• Substance Abuse
• Medical conditions like infections
• Prenatal damage
• Brain defects or injury

Common psychiatric disorders include Neurodevelopmental Disorders , Bipolar and Related Disorders , Anxiety Disorders , Stress-Related Disorders , Dissociative Disorders , eating disorders , and addiction.

Treatment for these conditions includes therapy, medication, or a combination of the two.

Find Time To Do This Several Times A Day Until Your Neurological Symptoms Pass

I really want you to find the time to get to the eye of the storm and to sit within that and connect with your intuition several times a day.

For me, I did it four or five times a day, whenever I could get a break from work, Id just try and sit still and really connect with me, with my real self.

Doing it several times a day really reinforces that separation from you and your worries and it reinforces that separation from you and your anxiety symptoms that are manifesting as neurological symptoms.

It means that you get that energetic space and that distance that you need to step into your own power to really feel yourself again, to feel you again and to know what its like to feel like you again.

How To Tell The Difference Between Anxiety And Neurological Disorders

Unfortunately, there is simply no way to tell the difference between suffering from anxiety and suffering from a more serious neurological disorder. The symptoms can look extremely similar, and while some may have some minor differences , the reality is there are often no differences.

This is why it is important to always see a doctor. Even though anxiety is extremely common, a doctor is the only way to accurately determine if a person does/does not have an underlying neurological disorder. Once a doctor rules out any neurological problems, it is important to begin to take steps towards controlling the anxiety. Unmanaged anxiety will lead to continued neurological symptoms, and ultimately, more anxiety.

In the extremely rare event that a person does have a neurological disorder, controlling anxiety is still important. Anxiety plays a significant role in not only happiness and overall wellbeing, but also in the success of medical treatments. If there is any reason to think that you have anxiety and not a neurological disorder, openly seeking help is incredibly important.

Brain Involvement The Norm Rather Than Exception

In the first study, published yesterday in the Journal of Neurology, Neurosurgery & Psychiatry, a team led by University College London researchers conducted a systematic review and meta-analysis of 215 COVID-19 studies from 30 countries involving 105,638 symptomatic COVID-19 patients from January to July 2020.

The most common symptoms were loss of smell , weakness , fatigue , loss of taste , muscle pain , depression , headache , and anxiety . The researchers also identified major but less common neurologic disorders such as ischemic stroke , hemorrhagic stroke , and seizures .

Among the few nonhospitalized COVID-19 patients with mild illness in the dataset, neurologic and psychiatric symptoms were still common, with 55% reporting fatigue, 52% loss of smell, 47% muscle pain, 45% loss of taste, and 44% headache.

In a University College London news release, lead study author Jonathan Rogers, BChir, said his team had expected neurologic and psychiatric symptoms to be more common in severe COVID-19. “But instead we found that some symptoms appeared to be more common in mild cases,” he said. “It appears that COVID-19 affecting mental health and the brain is the norm, rather than the exception.”

Anatomical And Neuroimaging Findings In Panic Disorder

Neuroimaging in patients who have panic disorder under resting conditions and under anxiety- or panic-provoking conditions has identified neuroanatomical alterations associated with symptom severity or treatment response.

Single-photon emission computed tomography identified lower metabolism in the left inferior parietal lobe and overall decreased bilateral cerebral blood flow in patients who had PD as compared with control subjects, and this decrease corresponded with symptom severity. Other studies, however, have demonstrated elevated glucose uptake in the amygdala, hippocampus, thalamus, midbrain, caudal pons, medulla, and cerebellum as measured by positron emission tomography . These elevations normalize after successful pharmacological or behavioral therapy, suggesting that the increased glucose uptake in these regions is state dependent. Patients who had PD had decreased frontal activity bilaterally but increased activity in the right medial and superior frontal lobe in SPECT studies. Interestingly, the CBF asymmetry and shift to the right hemisphere correlated with disorder severity in individual patients .

Genetic Contribution To Generalized Anxiety Disorder

Overall the genetic contribution is thought to be less substantial in GAD than in other anxiety disorders. Studies have shown that first-degree relatives of GAD probands have elevated rates of mood and anxiety disorders in general and perhaps have a specifically increased risk for GAD. A recent study of more than 3000 twin pairs found modest familial aggregation of GAD with equal heritability in males and females in same-sex or opposite-sex twin pairs there was no evidence for gender-specific genetic underpinnings of GAD. Results from twin studies estimate that approximately 32% of the variance for liability to GAD is caused by additive genetics in male and female twins and that the remaining variance is explained by environment specific to the individual, rather than the shared environment of the twin pair . Only a handful of genetic-association studies specific for GAD have been reported, and all are thus far unreplicated .
