Bipolar disorder affects about 1% of the French population—roughly 660,000 people—a number likely underestimated due to diagnostic challenges. It involves dramatic mood swings alternating between elation and depression. The World Health Organization ranks it among the top 10 most disabling conditions worldwide, severely impacting quality of life, social relationships, and sometimes leading to suicide attempts.
Often referred to in the plural as bipolar disorders, or historically as manic depression or manic-depressive psychosis, this chronic mental health condition causes intense, disproportionate mood fluctuations. These disrupt daily life, straining family and professional relationships.
Public Health data shows it impacts 1% of the population equally in women and men, typically emerging in young adults aged 15-25, though it can appear in adolescence or later in those over 60 or even 70.
In women, it often starts with a depressive episode; in men, a manic one characterized by obsessive ideas.
Individuals experience intense, prolonged cycles of elation (manic phases) and depression. Mania involves hyperactivity, aggression, and disinhibition, followed by profound sadness, overwhelm, and demotivation.
During manic episodes, people feel euphoric, grandiose, or irritable, with racing thoughts, impulsivity like excessive spending or starting multiple projects, and attention difficulties.
Depressive phases follow, marked by plummeting mood, loss of interest, vitality, and motivation—lasting weeks to months, often 2-3 times longer than mania. Suicidal ideation is common here, a key bipolar marker.
Intense mania correlates with deeper depression. Between episodes, remission periods allow normal mood and functioning.
The exact origins remain unclear, but biological factors—like impaired brain cell communication leading to mood instability and poor emotion regulation—play a role, often tied to genetics.
In predisposed individuals, triggers include stress from divorce, bereavement, job loss, relocation, shift work, illness, substance use (alcohol, tobacco, drugs), sleep deprivation, or rarely, medications like corticosteroids, NSAIDs, antidepressants, or Parkinson's drugs.
Diagnosis is challenging and often delayed by years—sometimes a decade—despite clear symptoms.
While not curable, mood stabilizers like lithium effectively regulate emotions, reducing episode frequency and severity. Long-term use, often lifelong, improves quality of life; discontinuation must be gradual.
Antidepressants may help depression but are used cautiously to avoid triggering mania.
For severe or treatment-resistant cases, electroconvulsive therapy (ECT, or seismotherapy) can be effective during acute phases.
Psychotherapy, especially psychoeducation, complements medication—teaching patients about the illness, adherence, and early relapse detection.
