Your brain operates electrically and chemically. Neurochemicals form the dynamic foundation for our thoughts and emotions. Many neurochemicals have been identified while many more have not. Neurochemicals important to mood include Serotonin, Neuropinephrine, Neuroadrenaline, and Dopamine. These neurochemicals remain in healthy balance for most of us, but for some there is imbalance and a mood disorder can result.

Effects of a mood disorder such as depression or mania include functional decline, interpersonal difficulty, and cognitive impairment. Depression is far more common than realized and represents a major chronic illness similar to high blood pressure. Depression not only affects the specific person, but it can also affect negatively those close to the patient and to potential colleagues. Depression and mania impairs thinking by reducing focus, attention, memory, and ability to execute plans. A depressed brain cannot process as deeply as necessary and this can result in rather significant cognitive impairment at times. Uncontrolled mania results in high distractibility, poor attention, and generally impaired cognitive functions across the board.

Treatments for mood disorder are effective and include use of antidepressants, mood stabilizers for mania, psychotherapy, and following a brain health lifestyle as espoused by Dr. Nussbaum (www.paulnussbaum.com). Use of software similar to that of FitBrains that helps to stimulate mental activity can also be of some use for a brain that may be sluggish. The most important thing is to first identify depression when it arises, take it seriously, and get some help.
