Several biologic theories are postulated for the pathogenesis of phobic disorders, most focusing on the dysregulation of endogenous biogenic amines. Sympathetic nervous system activation is common in phobic disorders, resulting in elevations in heart rate and blood pressure, as well as symptoms such as tremor, palpitations, sweating, dyspnea, dizziness, and paresthesias.
Phobias can have a serious impact on a person's lifestyle, due to the distress and symptoms suffered.
