A person’s moods alternate between two opposite ends, that is to say, from extreme sadness to euphoric happiness.   Most people start developing this behavior in their late teens but are well diagnosed in the age between 25 and 40 years. The cause is not clearly known but it is thought to result from chemical (neurotransmitters) imbalance. Imbalance of norepinephrine, serotonin and dopamine levels are believed to be the cause. Bipolar disorder has a genetic and environmental tie.   It can pass down through family members. However, it has to be triggered by some stress. Symptoms include behaviors revolving around mania and depression.   A sick person should be helped to find medical care especially when it threatens basic health.   Blood tests or X-rays are used to confirm the disorder. There is no cure for bipolar disorder. However, proper therapy can manage it and a sick person can go on functioning normally. Treatment is geared towards medication that stabilizes mood swings accompanied with counseling.   Medication is not very effective. Counseling is most successful especially with support from family members. Medication available for prescriptions in the market includes: lithium, valproic acid (depolcote) and Olanzine (zyprexa) among others.   They work by balancing neurotransmitters in the brain.   Some of their side effects include †¢ Lithium – increased urination, dizziness, nausea and diarrhea. †¢ Valproic acid – Drowsiness, weakness, nausea and diarrhea. †¢ Olanzapine – decreased alertness. 2.
