Anxious feelings and behaviors are classified as an anxiety disorder when they form a pattern of distressing, persistent anxiety or maladaptive behaviors that reduce anxiety.
People with generalized anxiety disorder feel persistently and uncontrollably tense and apprehensive for no apparent reason.
In the more extreme panic disorder, anxiety escalates into periodic episodes of intense dread.
Those with a phobia may be irrationally afraid of a specific object, activity, or situation.
Persistent and repetitive thoughts (obsessions) and behaviors (compulsions) characterize obsessive-compulsive disorder (OCD).
Symptoms of posttraumatic stress disorder (PTSD) include haunting memories, nightmares, social withdrawal, jumpy anxiety, and sleep problems following some traumatic experience.
Through conditioning, anxious or traumatized people may learn to associate their anxiety with certain cues. Stimulus generalization occurs when someone experiences a fearful event and later develops a fear of similar events. Reinforcement helps maintain learned fears and anxieties.
Cognition can influence our expectations and our interpretation of and reaction to stimuli. We may learn some fears by observing others’ fears. People with anxiety disorders tend to be hypervigilant: They attend more to threatening stimuli, more often interpret ambiguous stimuli as threatening, and remember threatening events.
Our biology also plays a role. Genetic predispositions for high levels of emotional reactivity and neurotransmitter production make us vulnerable to disorder, as do epigenetic marks. Abnormal responses in the brain’s fear circuits can create inroads for disorder. Natural selection and evolution have prepared us to fear the threats our ancestors faced.
