Clinical Definition

Claustrophobia is a persistent, irrational fear of enclosed spaces. The phobia, a type of anxiety disorder, triggers reactions and anxiety symptoms such as dizziness, nausea and tachycardia, which results in avoidance of situations or objects that trigger it. Desensitization, medication and cognitive therapy can help.
