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.
