Bipolar Disorder was formerly called manic depression. It is a mental health condition that causes a person to suffer from extreme mood swings that include emotional highs and lows.

The exact cause of Bipolar Disorder is unknown but some experts believe there are a number of factors that work together to make a person more likely to develop it. These are thought to be a complex mix of physical, environmental and social factors.

Bipolar Disorder is widely believed to be the result of chemical imbalances in the brain.

The chemicals responsible for controlling the brain’s functions are called neurotransmitters and include noradrenaline, serotonin and dopamine. There is some evidence that if there’s an imbalance in the levels of one or more of these neurotransmitters, a person may develop symptoms of bipolar disorder.

For example, there’s evidence that episodes of mania may occur when levels of noradrenaline are too high, and episodes of depression may be the result of noradrenaline levels becoming too low.
