What does trichotillomania refer to?

Trichotillomania is characterized by the recurrent and often compulsive pulling out of one's own hair, which leads to noticeable hair loss. This condition is classified as a mental health disorder within the category of obsessive-compulsive and related disorders. Individuals with trichotillomania may pull hair from various parts of the body, including the scalp, eyebrows, and eyelashes. The behavior is often driven by the urge to relieve tension or anxiety, and it can result in physical damage and emotional distress.

In contrast, the other options refer to different conditions that do not align with the definition of trichotillomania. Compulsive eating of non-nutritive substances is known as pica, while excessive cleaning or washing behaviors relate to obsessive-compulsive disorder. Frequent mood swings without cause could be indicative of mood disorders but do not pertain to hair-pulling behaviors. Understanding trichotillomania is essential for proper identification and treatment of the disorder.
