Information Needs and Data Harmonization-Two Sides of the Same Coin?

Trichotillomania (TTM), classified among the obsessive-compulsive and related disorders (OCRDs) in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) [], is characterized by recurrent pulling out of one’s own hair, resulting in clinically visible hair loss. Its prevalence is estimated at 1.7% in the adult general population, with a mean age of onset of 14.8 years in females []. Psychiatric comorbidity is common: in a Swedish national cohort of 1,234 patients, 79% had at least one associated psychiatric disorder, including anxiety disorders in 65% and neurodevelopmental disorders in 39% []. More than 20% of patients with TTM ingest the hair they pull, a behavior known as trichophagia []. This behavior is often concealed by the patient and may go unrecognized by the family []. When chronic, ingested hair accumulates in the gastric cavity to form a trichobezoar, a compact mass that resists digestion due to its keratin composition, and may cause obstruction, ulceration, or digestive hemorrhage [-]. Anemophobia refers to an intense, persistent fear of wind and of objects set in motion by wind. It is not a distinct entity in the DSM-5-TR but corresponds to a specific phobia of the natural-environment type []. We report this case in light of the distinctive temporal sequence of the disorders and their occurrence in a patient presenting with both intellectual disability and anemophobia, a combination that has not, to our knowledge, been previously described in this specific configuration.
