[9] Generalized anxiety disorder has been linked to changes in functional connectivity of the amygdala and its processing of fear and ...
Anxiety disorders affect nearly 30% of adults at some point in their lives, with an estimated 4% of the global population currently experiencing an anxiety disorder. However, anxiety disorders are treatable, and a number of effective treatments are available. [11] Most people are able to lead normal, productive lives with some form of treatment ...

Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
hooc−ch 2 −ch 2 −ch(nh 2)−cooh → co 2 + hooc−ch 2 −ch 2 −ch 2 nh 2 In mammals, GAD exists in two isoforms with molecular weights of 67 and 65 kDa (GAD 67 and GAD 65 ), which are encoded by two different genes on different chromosomes ( GAD1 and GAD2 genes, chromosomes 2 and 10 in humans, respectively).
Physiological hyperarousal is unique to anxiety disorders. [2] [12] Some symptoms of physiological hyperarousal include: shortness of breath, feeling dizzy or lightheaded, dry mouth, trembling or shaking, and sweaty palms. [13] [14] Compared to negative affect and positive affect, physiological hyperarousal has been studied less.
