People with bipolar disorder experience extreme emotional highs and lows and may sometimes have trouble controlling their emotions. For instance, they may react to daily events with deep sadness or extreme joy.
People with bipolar disorder go through periods with wide mood swings. These periods are called “episodes”. The frequency, duration and intensity of these episodes vary from person to person. Some people with bipolar disorder may have a hard time fulfilling their professional, family and social obligations. However, these episodes may be interspersed with periods in which their mood is “normal”.

Care and services
Treatments with recognized effectiveness are available, along with psychosocial interventions that allow people to improve their daily functioning and personal balance. Treatments relieve the symptoms of bipolar disorderand help people regain control over their lives and daily activities. The earlier people seek help, the better their chances of recovery.
In most cases, bipolar disorder is treated with psychological interventions (psycho-education, problem solving, cognitive-behavioural therapy, etc.) and medication.
Taking part in complementary interventions aimed at healthy living or stress management, or joining a support group can also be helpful.

Bipolar disorder is not always preventable, but if you have symptoms associated with it, you should act immediately. The tips for maintaining good mental health will help you change certain lifestyle habits.

There is no single cause for bipolar disorder. Rather, it is often the result of a combination of several factors. Here are a few of these factors:
- Biological factors: heredity, that is, other family members have or have had it
- Social factors: the presence of stressors in the person’s life
- Environmental factors: alcohol and drug abuse and addiction.
Recent studies on the causes of bipolar disorder suggest that it is the result of a biochemical imbalance in the brain combined with a person’s emotional and physical vulnerability to stress.
People at risk
Bipolar disorder affects about 1% of the population. It usually begins in adolescence or early adulthood.
Bipolar disorder can affect anyone, regardless of age, sex, social status, education, nationality or ethnic origin.
