About mood disorders
Mood is a state of mind predominated by a specific emotion, such as anger, sadness or joy. Emotions can be pleasant or unpleasant, and sometimes painful. We can usually control them.
People with a mood disorder experience negative emotions more intensely and for a longer period than others. They may have a difficult time controlling their emotions, which in turn affects their mental and physical health, as well as influencing their behaviour.
People with a mood disorder have a hard time fulfilling their professional, family and social obligations.

Mood disorders can be treated with recognized treatments. Treatment allows people suffering from mood disorders to regain control of their lives and daily activities. The earlier you seek help, the better your chances of recovery.
In most cases, mood disorders can be healed through psychotherapy, with medication, or a combination of the two.

Other therapies are also available depending on the type of mood disorder and on the patient’s needs.

Recommendations regarding medication
If your doctor prescribes medication, it is important that you follow the instructions carefully.
You must also be patient in waiting for results. It can take up to 4 to 8 weeks before the medication produces maximum results.
Even if you feel better, you must continue the treatment as prescribed in order to avoid the reoccurrence of symptoms.
If you experience undesirable side effects, discuss them with your pharmacist or doctor as soon as possible. If necessary, your medication could be adjusted or other medication may be recommended.
Protection and prevention
Mood disorders are not always preventable, but if you have symptoms associated with them, you should act immediately. The tips for maintaining good mental health will help you change certain lifestyle habits. These changes will help improve your health and reduce the factors that worsen or influence your symptoms.
Mood disorders do not have a single cause. A combination of many factors lead to mood disorders. Factors may include the following:
- Heredity: Other family members have the illness or have suffered from it in the past
- Previous episode of depression, which increases the chance of a relapse
- Alcohol and drug abuse or dependence
- Presence of stress factors in a person's life. These factors can be related to family, social or professional environment
- Changes in the balance of certain neurotransmitters or hormones
- Having certain other illnesses, such as:
- Cardiovascular disease
- Parkinson’s disease
- Lung disease
- Other chronic diseases
People at risk
Mood disorders can affect anyone, regardless of age, sex, social status, education, nationality or ethnic origin.
People with a mood disorder are sometimes victims of their own prejudices and those of society. These prejudices discourage people from seeking help or continuing their treatment. To learn more about prejudices and how to fight them, read Fighting the stigma surrounding mental illness.
