Alzheimer's drug shows promise in trichotillomania and skin-picking disorder

In randomized trial involving 100 adults with trichotillomania or skin-picking disorder (86 women; mean age, 31.4 years), 60.5% of memantine recipients were “much or very much improved” at 8 weeks compared with 8.3% of placebo recipients (number needed to treat, 1.9). The rate of adverse events was similar between groups.
