What term means an abnormal fear of narrow, enclosed spaces?

• A. Concussion
• B. Claustrophobia
• C. Encephalitis
• D. Hyperesthesia

Answer: (B)

Claustrophobia is the fear of narrow, enclosed spaces. It’s a specific phobia, meaning the fear is excessive and leads to avoidance of situations like elevators, small rooms, or crowded spaces. The word comes from Greek roots meaning “closed” and “fear.” Symptoms often include rapid heartbeat, sweating, dizziness, and a strong urge to escape when in confined spaces. The other terms refer to different medical issues: concussion is a brief brain injury with possible confusion or loss of consciousness; encephalitis is brain inflammation usually due to infection; hyperesthesia is an increased sensitivity to sensory stimuli. So claustrophobia best fits the description of an abnormal fear of narrow, enclosed spaces.
