These people have very fast thinking which leads to the other person having a conversation with them only able to get a few words in. A manic state can last a few days, or a few months, it generally ends abruptly. The depressive episode usually lasts three times as long. The chances of having bipolar disorder are very low ranging from 0, Sand 1.6% (Hammen & Keenan-Miller,2013) but this disorder can be one of the most lethal disorder, People with bipolar disorder has a suicide rate of ten to twenty percent of suffers. Suicide is also a serious risk for anyone suffering from any other mental health issues, particularly depressive disorders,

Bipolar and Depressive disorders have biological factors that look important in both. For instance, bth disorders can be treated with antidepressants, which affect the amount of dopamine and serotonin in the brain. Recent studies suggest that structural changes in the brain contribute to these disorders. Unfortunately, NF players are at greater risk of developing depression as they age, possibly due to brain damage, One recent study on former NFL. players revealed that 41% show cognitive problems and 24% show clinical depression, which may result
from neurological changes caused by concussions (Harter al, 2013). Their brain scans also reveal changes in blood flow within the brain and changes in various parts of the brain. These changes can lead to serious depression or the risk of suicide. Other research points to imbalances of the neurotransmitters serotonin, and dopamine as possible causes of mood disorders.

Drugs alter the activity of these neurotransmitters and also decrease the symptoms of depression and are therefore called
antidepressants (Chuang, 1998), Interestingly, researchers in one study found that people who regularly ate fast food and commercially produced baked goods were 51% more likely to develop depression later. This may be a result of the chemicals in such foods leading to physiological changes in the brain and body (Sanchez-Villegas et al., 2011). Some biological research that both depressive and bipolar disorders may be inherited.
