ABSTRACT
Trichotillomania (TTM) is frequently considered an isolated disorder; nevertheless, emerging evidence suggests that other psychiatric conditions including obsessive-compulsive disorder (OCD); eating disorders (EDs); and attention-deficit/hyperactivity disorder (ADHD) are often found to coexist. Several studies showed that EDs, such as bulimia nervosa (BN), were found in chronic hair-pullers, whilst OCD was considered a factor in predicting the prevalence of EDs, as well as the severity of TTM in the populations. While the relationship between TTM with OCD has been quite well-documented, the evidence of its association with BN and ADHD remains limited.
