Mood Disorders All People Experience Mood Changes. Term Paper

Mood Disorders All people experience mood changes. We are happy or sad. We may be overjoyed or in despair, but our reactions are in proportion to the situations we face. In mood disorders, this balance is not present. Moods are extreme. Depression is a sad state where things seem hopeless. Mania is elation or extremely heightened energy.

Cause: Depression is often triggered by some major event, although sometimes the cause may be within the individual (biological). Biology, psychological, and social factors may all play a part. Genetics are implicated for some people and may provide a predisposition to the disorder, as has been indicated in adoptive studies that rule out common environmental triggers among biological twins separated at birth. Neurotransmitters appear to play an important role in depression, which is why medication can play an important role in treatment.
