in those with bipolar disorder, two major areas of the brain contain 30 percent more cells that send signals to other brain cells
-
This report theorizes that "the extra signal-sending cells may lead to a kind of overstimulation, which makes sense considering the symptoms of bipolar disorder
-
Most scientists believe that mental illnesses are caused by a combination of several factors working together. In bipolar disorder, these factors are usually divided into biological and psychological causes. In plain English, the main reasons mental illness develops are physical (biological) and environmental.
-
Some studies suggest that a low or high level of a specific neurotransmitter such as serotonin, norepinephrine or dopamine is the cause.
-
Other studies indicate that an imbalance of these substances is the problem, i.e., that a specific level of a neurotransmitter is not as important as its amount in relation to the other neurotransmitters(2).
-
- Still other studies have found evidence that a change in the sensitivity of the receptors on nerve cells may be the issue(4).
-
ith that in mind, research has found that stressful life events can lead to the onset of symptoms in bipolar disorder.
-
However, once the disorder is triggered and progresses, "it seems to develop a life of its own." Once the cycle begins, psychological and/or biological processes take over and keep the illness active(2).
