However, the genetics of TTM is a complex subject and needs more research.
Mutations in Hoxb8 and Sapap3 genes may also cause TTM-like behaviours. It says that TTM is linked to rare variations in the SLITRK1 gene, which may trigger OCD in individuals, followed by TTM. Genetic anomalies: A study talks about TTM in three generations of families.Dysfunction in brain structures: A study has shown that reduced cerebellar volumes and thickening of the right inferior frontal gyrus (brain part involved with cognition, attention, imagery and speech) can be some of the problems related to the brain structures which may lead to TTM.The cause of stress and anxieties could be related to genetic anomalies, dysfunction of the brain neurotransmitters, dysfunction in brain structures and OCD-related disorders. This behaviour leads to obsession or say becomes a learned habit of the patients in which they start pulling their own hair in a repeated way whenever they feel stressed out. Stressful conditions and chronic anxieties may urge people to pull their own hair to get relief or deal with negative emotions. The exact cause of TTM is still unknown, however, stress and anxiety are considered to be the main causes of the condition.
