What should I know about bipolar disorder (manic-depression)?


Bipolar disorder (or manic-depressive illness) is closely related to depression. It is a bio-chemical condition that results in an imbalance of the neurotransmitters in the brain.  This condition may genetic and may be passed down through a family. Environment, stress, injury, illness and hormone imbalances may also play a role.

Bipolar disorder affects about 3% of the general population and causes severe mood swings that can last for days, weeks or even months. These mood swings can range from mild to extreme and can even result in psychosis and hallucinations. Usually the mood swings are separated by periods of normal health. About 80% of all people with this disorder can be effectively treated with a number of different medications. However, only about one in three people with this disorder ever gets appropriate help. If it’s not treated, the illness can cause major difficulties with work, school, interpersonal relations and dealing with daily stress.

There are a number of forms of bipolar disorder, ranging from mild symptoms of depression or mania to very severe symptoms that might even require hospital treatment. Some people have more frequent cycles than others. Many people with the less severe forms of bipolar illness are not as disabled as people who have more intense symptoms and are able to continue their social and working lives. Still, their symptoms and behaviour can be quite difficult for others to understand.

Symptoms of mania can include the following:

  • feelings of invincibility
  • more physical energy
  • less need for sleep
  • inappropriate excitement
  • irritability or excessive anger
  • increased activity, talking and moving
  • increased sexual thoughts and activity, sometimes resulting in promiscuity and inappropriate or unsafe behaviour
  • disconnected and racing thoughts
  • racing speech
  • loss of self-control and impulsive or reckless behaviour
  • inappropriate spending
  • hallucinations and delusions.

Some symptoms of depression may include:

  • feelings of sadness and loss
  • feelings of guilt and worthlessness
  • feelings of extreme impatience, irritability, or a short temper
  • loss of interest or pleasure in usually-enjoyed activities
  • changes in weight or appetite
  • changes in sleeping patterns like insomnia
  • reduced ability to think clearly or make decisions
  • difficulties in concentrating or with short-term memory loss
  • constantly feeling tired
  • noticeable lack of motivation
  • anxiety and restlessness, sometimes leading to panic attacks
  • muscle and joint pain
  • constipation or other intestinal problems
  • frequent headaches
  • lack of interest in sex
  • recurring thoughts of suicide or self-harm
  • withdrawal from friends and family.
