Biological processes of generalized anxiety
Generalized anxiety disorder (GAD) is a common mental illness with no known treatment or cure. Patients who suffer from GAD experience long-term, excessive anxiety that is both severe and out of proportion to the situation. The causes are not clear, but it is thought to be a result of neurological, genetic, and environmental factors. Its sufferers feel constant and intense worry about multiple situations, people, and places. It can include panic attacks, muscle tension, sweating, headaches, nausea, tight chest pains and difficulty concentrating.
There are several biological processes that take place in GAD patients:
The amygdala makes abnormal connections with other areas of the brain
Hippocampus has abnormal neuron activity
The hypothalamus produces higher than normal levels of corticotropin-releasing hormone (CRH)
The hippocampus and prefrontal cortex communicate abnormally
There is an increase in stress-related hormones such as cortisol
