NewsMedical - Factors linked to bipolar cycle acceleration identified

By Eleanor McDermid, Senior medwireNews Reporter

Researchers have identified factors that are associated with cycle acceleration in patients with bipolar disorder admitted to hospital for a mood episode.

These factors included being female, having type II rather than type I bipolar disorder and experiencing increasing severity of affective episodes.

These variables have previously been highlighted in patients with rapid cycling, but have received little attention in relation to cycle acceleration, say the researchers, led by Per Finseth (Norwegian University of Science and Technology, Trondheim).
