World Bipolar Day is celebrated every year on March 30, the anniversary of the birth of painter Vincent van Gogh - whose presumed bipolar disorder profoundly affected his work and life. The event aims to reduce the stigma associated with this serious psychiatric condition, and to raise public awareness of its detection and management. Bipolar disorder affects approximately 2 to 3 % of the world's population, all forms taken together, representing several hundred thousand Quebecers. Despite its prevalence, it remains one of the psychiatric disorders most often diagnosed late - with an average delay of six to ten years between the first symptoms and correct diagnosis.
This delay in diagnosis is partly due to the fact that sufferers most often seek help during depressive episodes, leading to an initial diagnosis of unipolar depression. Manic or hypomanic episodes can be experienced positively - increased energy, creativity, feelings of omnipotence - and do not always lead to consultation. However, inadequate treatment of bipolar disorder - notably with antidepressants alone without mood stabilizers - can trigger manic episodes and worsen the course of the illness.
What is bipolar disorder: definition and clinical forms
Bipolar disorder is a psychiatric condition characterized by marked and recurrent fluctuations in mood, energy and behavior, oscillating between episodes of depression and episodes of thymic elevation - mania or hypomania. There are several clinical forms recognized in the DSM-5. Type I bipolar disorder is defined by the presence of at least one full manic episode - lasting at least one week, and severe enough to impair functioning or require hospitalization. Depressive episodes are present in the vast majority of patients, but are not required for diagnosis.
Type II bipolar disorder is characterized by hypomanic episodes - a less intense form of mania, lasting at least four days, without severe impairment of functioning or psychotic features - and depressive episodes. It is often under-diagnosed, as hypomania can be difficult to distinguish from normal «energetic» functioning, and patients consult mainly for depression. Cyclothymia refers to a milder form with chronic mood fluctuations but below the full diagnostic thresholds for mania or major depression.
Manic and hypomanic episodes: recognizing the signs
A manic episode is characterized by a marked elevation or expansiveness of mood - euphoria, intense irritability or grandiosity - accompanied by reduced need for sleep without fatigue, logorrhea and rushed speech that is difficult to interrupt, flight of ideas or acceleration of thought, increased distractibility, increased goal-directed activity and impulsivity with engagement in high-risk activities - reckless spending, risky sexual behavior, impulsive investments, dangerous driving. In severe forms, psychotic symptoms may be present - delusions of grandeur, hallucinations.
Hypomania has the same characteristics, but is less intense and has no severe functional consequences. The person often feels at their best - productive, creative, sociable, not very sleepy, but not tired. This is why these episodes are rarely spontaneously reported as problematic. It's often those around them who observe the change in behavior. Even a brief history of hypomania is decisive in making the diagnosis of Type II bipolar and radically changing the treatment strategy.
Bipolar depression: differences from unipolar depression
Bipolar depression shares many symptoms with unipolar depression: persistent depressed mood, anhedonia, fatigue, sleep and appetite disturbances, difficulty concentrating, negative thoughts or suicidal ideation. However, certain features are more common in bipolar depression, and may help guide the diagnosis: hypersomnia rather than insomnia, hyperphagia rather than anorexia, marked psychomotor slowing, diurnal mood fluctuations with morning worsening, and an often partial or unstable response to antidepressants - even triggering a hypomanic or manic turn.
The presence of suicidal risk is particularly high in bipolar disorder - studies indicate that 25-50 % of sufferers attempt suicide at least once in their lifetime, and that the suicide death rate is twenty times higher than in the general population. This underlines the urgent need for accurate diagnosis and appropriate treatment.
How is bipolar disorder diagnosed?
The diagnosis of bipolar disorder is clinical - based on a thorough psychiatric interview, a longitudinal history of thymic episodes, and the use of standardized assessment tools. There are no biomarkers or diagnostic laboratory tests. The history should explore not only current depressive episodes, but also a history of mood elevation episodes, even brief ones, and family history - bipolar disorder has one of the highest heritabilities in psychiatry, around 70 to 80 %. Several clinical scales help structure the assessment, including the MDQ - Mood Disorder Questionnaire - and the HCL-32 for detecting hypomanic history.
A full medical work-up is also necessary to rule out organic causes of thymic instability - hyperthyroidism, neurological disorders, substance abuse - and to assess frequent comorbidities: anxiety, ADHD, substance use disorders. These comorbidities are present in a majority of bipolar patients and must be integrated into the treatment plan.
Available treatments: stabilizing mood and preventing relapses
Treatment of bipolar disorder has two complementary aims: to treat acute episodes - whether depressive, manic or mixed - and to prevent long-term relapses. Mood stabilizers are the cornerstone of treatment: lithium remains the reference treatment with the most robust evidence for preventing recurrence and reducing suicidal risk. It requires regular monitoring of blood levels and renal and thyroid function. Valproic acid - valproate - and lamotrigine are other stabilizers used according to the predominant thymic profile.
Some atypical antipsychotics - quetiapine, olanzapine, aripiprazole, lurasidone - have been shown to be effective both in acute episodes and in maintenance treatment. Psychoeducation - learning to recognize prodromal symptoms and triggers - is an essential component of treatment, and significantly reduces relapse rates. Regular sleep, limiting alcohol and cannabis consumption, and stress management are particularly important hygienic and dietary measures in this condition.
Frequently asked questions about bipolar disorder in Quebec
How do I know if I'm bipolar or just moody?
Normal mood fluctuations are part of the human experience. What distinguishes bipolar disorder is the intensity, duration, recurrence and functional impact of the episodes. A hypomanic episode lasts a minimum of four consecutive days, with an observable change in mood; a manic episode lasts a minimum of one week and significantly alters functioning. If you have periods when you sleep much less without being tired, spend inconsiderately, talk or think very fast, feel invincible - alternating with periods of depression - a medical assessment is strongly recommended.
Are antidepressants dangerous if you're bipolar?
Antidepressants can be problematic in bipolar disorder when used alone, without coverage by a mood stabilizer. They can trigger a manic or hypomanic turn, accelerate cycling - the alternation of episodes - or induce unstable mixed states. This is one of the reasons why it's crucial to distinguish bipolar from unipolar depression before prescribing treatment. When used in bipolar disorder, antidepressants are generally combined with a mood stabilizer and prescribed with caution. The decision rests with the doctor after a full evaluation.
Can bipolar disorder be managed without medication?
For the vast majority of people with type I or II bipolar disorder, medication is necessary to stabilize mood and prevent relapses. Untreated relapses have cumulative consequences on the brain, social and occupational functioning, and increase the risk of suicide. That said, medication alone is rarely sufficient: psycho-education, cognitive-behavioural psychotherapy tailored to bipolar, support groups and healthy lifestyle measures are essential components of comprehensive management. Discontinuation of medication without medical supervision is associated with a very high relapse rate.
Can I come to Clinique Omicron for an evaluation of bipolar disorder without a psychiatrist?
Yes, in many of our Quebec branches, a physician can perform an initial assessment of bipolar disorder, make the diagnosis in clear cases, initiate or adjust mood-stabilizing treatment, and provide regular follow-up. For complex situations - resistance to treatment, multiple psychiatric comorbidities, high suicidal risk - a psychiatric referral will be planned. Prompt medical assessment can help avoid the years of misdiagnosis and inadequate treatment that too often characterize the lives of bipolar sufferers in Quebec.
