What Causes Trichotillomania?

Functional Or Structural Brain Abnormalities

There are many psychologists and scientists who believe functional or structural brain abnormalities may cause trichotillomania. Studies have found the orbital frontal cortex, caudate nucleus, and thalamus could potentially cause trichotillomania if they become structurally or functionally abnormal because each plays a key role in suppressing and controlling unwanted, obsessive thoughts. Data in this field of study is still in its infancy, so the specific regions of the brain that may or may not be involved are still somewhat uncertain. Additionally, the mechanism through with these structural or functional abnormalities may contribute to trichotillomania are still unknown. More research is still needed, and the research currently out is conflicting in regards to this mechanism.
