10 September, 2025

Dear HIFA colleagues, (with thanks to Jackeline Alger, lead moderator HIFA-Spanish)

WHO has updated its fact sheet on bipolar disorder. Read in full here: https://www.who.int/news-room/fact-sheets/detail/bipolar-disorder

KEY FACTS

Bipolar disorder is a mental health condition that affects a person’s mood, energy, activity and thought and is characterized by manic (or hypomanic) and depressive episodes.

An estimated 1 in 200 (or 37 million) people live with bipolar disorder worldwide.

Bipolar disorder is associated with significant disability and difficulties in many areas of life.

Many people with bipolar disorder are misdiagnosed or untreated and experience discrimination and stigma.

There are a range of effective care options, which combine medicines and psychosocial interventions to help people with bipolar disorder stay well.

WHO response

The Comprehensive mental health action plan 2013-2030 highlights the steps needed to provide appropriate services for people with mental health conditions, including bipolar disorder.

COMMENT (NPW): We note in particular that 'Many people with bipolar disorder are misdiagnosed or untreated and experience discrimination and stigma'. This recent paper notes that 'Misdiagnosis of bipolar disorder (BP) is common in psychiatry clinics, with at least 20.8 − 61.5% of patients with BP being mistakenly diagnosed as having major depressive disorder (MDD)'. https://bmcpsychiatry.biomedcentral.com/articles/10.1186/s12888-024-05810-3

I would be grateful to hear your experience and comments.

Best wishes, Neil
