The cause and mechanism of bipolar disorder is not yet known, and the study of its biological origins is ongoing. Although no single gene causes the disorder, a number of genes are linked to increase risk of the disorder, and various gene environment interactions may play a role in predisposing individuals to developing bipolar disorder.
Mania is a syndrome with multiple causes. [6] Although the vast majority of cases occur in the context of bipolar disorder, it is a key component of other psychiatric disorders (such as schizoaffective disorder, bipolar type) and may also occur secondary to various general medical conditions, such as multiple sclerosis; certain medications may perpetuate a manic state, for example prednisone ...
The causes of bipolar disorder likely vary between individuals and the exact mechanism underlying the disorder remains unclear. [48] Genetic influences are believed to account for 73–93% of the risk of developing the disorder indicating a strong hereditary component. [9] The overall heritability of the bipolar spectrum has been estimated at 0 ...
Onset of Bipolar Disorder. Signs of bipolar disorder generally emerge in young adulthood. Research suggests that 70 percent of people with bipolar disorder experience their first manic episode ...
Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
The more extreme form of mania can cause highly noticeable problems at work, school and at home and in social situations, according to Mayo. In some cases, people in a manic phase can break from ...
Mood disorders fall into seven groups, [2] including; abnormally elevated mood, such as mania or hypomania; depressed mood, of which the best-known and most researched is major depressive disorder (MDD) (alternatively known as clinical depression, unipolar depression, or major depression); and moods which cycle between mania and depression ...
While there is limited understanding regarding the development of bipolar disorder, research shows that there are many environmental and biological risk factors. [2] Family history is a strong predictor of childhood development of bipolar disorder, with genetics contributing to risk by up to 50%.
