Hypersexual features in Huntington's disease.

We report the case of a 30-year-old woman with a rare presentation of early adulthood Huntington's disease (HD) with hypersexuality. It is not known if sexual dysfunction in HD patients is due to a specific brain lesion or adverse psychosocial factors associated with HD. Although there are no evidence-based treatment guidelines for hypersexuality in HD, our patient exhibited significant improvement with olanzapine and haloperidol.
