Reseach into Bipolar Disorder

Bipolar disorder (also known as manic-depressive illness) is a brain disorder that causes random and extreme changes in mood and energy levels. The changes in mood differ alot from the mood swings that everybody else experiences now and again. They are severe and very obvious. The illness, however, can be treated.

It is uncommon for Bipolar disorder to start in childhood and in most cases the symptoms will start showing from teenage years to young adulthood. It is also uncommon for Bipolar disorder to only start showing symtoms later than this. A study taken shows that at least half of all cases start before the age of 25.
Although the symptoms for Bipolar are easy to spot if you know what your looking for and may seem obvious, it is not easy to spot at the start as the symptons could look like seperate problems depending on how the person is reacting to them.
The phrase used to describe the two different personas that a person suffering from Bipolar disorder will go through is "mood episodes". A 'manic episode' is when the person is in an overly joyful and energetic state and an extremely sad or hopeless state is called a 'depressive episode'. Occasionally, their mood can reflect both a depressive episode and a manic episode and this is called a 'mixed state'. Whatever state they happen to be in, it can change instantly and they can suddenly explode for no reason.
