A person having hypomanic episode experiences an elevated mood and feels much better than usual. Hypomanic episodes are often followed by depression.

Causes of Bipolar disorder
Although the exact cause of bipolar disorder is not known yet, various researchers suggest that genetics, environment, and chemicals in the brain can play a role in the development of this disorder. The chances of developing bipolar disorder are increased when an individual’s parents or siblings have already suffered from this disorder. However, just because one family member has this disorder does not necessarily mean that other family members will also develop this disease.
Environmental factors are also known to contribute to the development of bipolar disorder. Stress is said to be the number one environmental factor that triggers the symptoms of this disease. Emotional factor in the life can cause it. Other than stress, seasonal factors can also play a role in the onset of this disorder. Increase in the hours of sunshine can trigger manic or depressive episodes.
Numerous studies show that changes in the brain chemicals can also contribute to the occurrence of this disease. Abnormal serotonin level in the brain is associated with bipolar disorder. Serotonin is a chemical in the brain which acts as a neurotransmitter and have a strong impact on the mood. Whenever any abnormal changes occur in this chemical, the risk of developing bipolar disorder increases. Serotonin is one of the neurotransmitters in the brain and other neurotransmitters can also be involved in this disorder.
