Abstract:
Klinefelter syndrome (KS) is widely associated with cognitive impairment and language problems. KS patients may also exhibit psychiatric symptoms. We present the case of an 18-year-old man with KS who experienced rapidly repeating relapses of manic episodes. He was unresponsive to the usual pharmacotherapies for bipolar disorders such as mood stabilizers and second-generation antipsychotics. Mood was eventually improved with testosterone therapy in addition to pharmacotherapy, with no relapse of manic episodes for 3 years after discharge. Testosterone therapy may prevent relapsing manic episodes of bipolar disorder in patients with KS.
