But researchers don't know exactly what causes anxiety disorders. They suspect a combination of factors plays a role: Chemical imbalance: Severe or long-lasting stress can change the chemical balance that controls your mood. Experiencing a lot of stress over a long period can lead to an anxiety disorder.
Epinephrine is just one chemical involved in your body's response to anxiety. Other chemicals may also play a role. For example, a serotonin imbalance¹ may contribute to anxiety, as can high cortisol levels. However, epinephrine is the primary chemical because it is directly involved in your anxiety symptoms.
Treatment for Chemical Imbalances
Therapy may involve different treatments such as cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), or family-focused therapy. Medications used to treat chemical imbalances include antidepressants, antipsychotics, and mood stabilizers.
The “Chemical Imbalance” Theory
The neurotransmitters serotonin, dopamine, norepinephrine, and gamma-aminobutyric acid (GABA) are specifically believed to be linked to mood and anxiety disorders.
An imbalance of naturally occurring brain chemicals — such as serotonin, dopamine and norepinephrine — is often seen in people with GAD and could be an indicator of a propensity to develop the disorder, according to the Mayo Clinic.
Anxiety can be caused by a variety of things: stress, genetics, brain chemistry, traumatic events, or environmental factors. Symptoms can be reduced with anti-anxiety medication. But even with medication, people may still experience some anxiety or even panic attacks.
Anxiety disorders are very treatable. Most patients who suffer from anxiety are able to reduce or eliminate symptoms after several (or fewer) months of psychotherapy, and many patients notice improvement after just a few sessions.
Anxiety disorders are the most common of mental disorders and affect nearly 30% of adults at some point in their lives. But anxiety disorders are treatable and a number of effective treatments are available.
In that sense, a chemical imbalance in the brain can't be “fixed.” Brain chemistry can be influenced by some medications such as antidepressants and antipsychotics. These have been shown to help improve the symptoms of mental health conditions associated with a chemical imbalance in the brain.
Thus ended the “chemical imbalance” theory cause for mental illness, including anxiety disorder. So, no, anxiety disorder is not caused by a chemical imbalance in the brain.
Here are some of the most common signs and symptoms of chemical imbalances: Overeating or loss of appetite. Restlessness. Insomnia or sleeping too much.
Anxiety happens when a part of the brain, the amygdala, senses trouble. When it senses threat, real or imagined, it surges the body with hormones (including cortisol, the stress hormone) and adrenaline to make the body strong, fast and powerful.
Abnormalities in a brain neurotransmitter called gamma-aminobutyric acid — which are often inherited — may make a person susceptible to GAD. Life events, both early life traumas and current life experiences, are probably necessary to trigger the episodes of anxiety.
Patience is key. After finding the right treatment, most people show improvement in their symptoms within 6 weeks.
What is the cause or basis of ADHD? It is an impulse disorder with genetic components that results from imbalances of neurotransmitters.
Getting enough sleep, exercising, listening to music, meditating, and spending time in the sun can all boost dopamine levels. Overall, a balanced diet and lifestyle can go a long way in increasing your body's natural production of dopamine and helping your brain function at its best.
Anxiety is an emotion characterized by feelings of tension, worried thoughts, and physical changes like increased blood pressure.
Feelings of anxiety are likely to pass with time as we get used to the "new normal" but it's important to do what we can to take care of our mental health. There are lots of things that can help you to manage these feelings and make it easier to adjust.
