Biochemical Causes
Biochemically speaking, bipolar disorder takes place in a certain part of the brain where a number of neurotransmitters (a sort of chemical messenger) are said to have been malfunctioning. Dopamine, serotonin, and norepinephrine are just the three, maybe a lot more, of neurotransmitters involved in bipolar disorder. With this in mind, the disorder may be just sleeping or dormant for years and can be set off by some external factors such as stress or crisis. A closer look at the brain research scientists have discovered that a patient’s brain suffering from the disorder is “wired differently” from the normal person, which may explain the maddening alterations of extreme emotions.
