Bipolar disorder (manic depression)

Bipolar disorder is often hard to diagnose and is commonly confused with depression (being the prevailing mood state). Bipolar disorder is a mental illness characterised by episodes of mania and depression and extreme highs and lows in mood. A good way to identify this condition is when an individual is always depressed and low to the point of not getting out of bed then suddenly springs into action, has a flight of ideas and dramatically increases their activity (e.g., stays up all night to clean the house) and this lasts for at least a week.

What are the signs?

A manic episode involves an elevated or irritable mood and increases in activity levels at work and social engagements. Other signs include:

  • excessive involvement in pleasurable activities that will have an undesirable consequence
  • reckless spending
  • rapid speech
  • subjective impression that thoughts are racing
  • less than normal amount of sleep
  • inflated self-esteem or belief that one has superhuman powers

The average age of onset for the disorder is for people in their late 20's and it occurs equally in men and women. In women the episodes of depression are more common and episodes of mania less common than among men. The prevalence of bipolar disorder is life long.

What are the causes?

The causes of Bipolar Disorder are largely unknown. There is a moderate heritability for the disorder but it is essentially a combination of biological, psychological and environmental factors.

How is bipolar disorder treated?

Prescribed medication is very helpful for treating bipolar disorder but it must be carefully monitored as side effects are common. Counselling is useful for appropriate management of mood states, education around the disorder and support in living with the disorder.
