Anxiety is a feeling of worry, nervousness, or unease, typically about an imminent event or something with an uncertain outcome. Anxiety disorder is a nervous disorder characterized by a state of excessive uneasiness and apprehension, typically with compulsive behavior or panic attacks.
Serotonin, nor epinephrine, dopamine and GABA (gamma-aminobutyric acid)are the common neurotransmitters that mediate anxiety symptoms in the central nervous system (CNS). Sympathetic nervous system mediates peripherally.
Pure Anxiety often results from too much activity in the basal ganglia, setting one’s “idle speed” on overdrive. People with pure anxiety often feel a great deal of tension and nervousness, and are overwhelmed by feelings of panic, fear and self-doubt; they tend to predict the worst and look to the future with fear.
Genetic studies support the evidence that anxiety disorders run in families.
