Case report: cause of hyperprolactinemia in an elderly patient.

Irritation to the chest wall due to herpes zoster virus (HZV) infection is one of many potential underlying causes of hyperprolactinemia. Hyperprolactinemia can lead to various different symptoms including anorgasmia. It is important to identify any sexual dysfunction, but also any other symptoms of hyperprolactinemia, in elderly patients during medical history taking and not to assume that elderly people are sexually inactive. Anorgasmia and any other sexual dysfunction in elderly can have an impact on their mental health and may even lead to depression and anxiety.
