My brother has bipolar disorder. what are the modern techniques to cope with this?

Bipolar treatment: With bipolar you are aiming for as close to "normal" as possible. When medications are balanced your brother's life will feel closer to "normal." psychotherapy will help him learn to cope with life stressors better, too. When the medications keep him balanced, he will function and take advantage of therapy better. The illness does not go away, but he can learn to manage it better.
