The sufferer alternates between periods of extreme euphoria and elation i.e., mania, and bouts of
depression.
·
Side Effects of Mood Disorders
·
The height of elation may lead to high creative output, although it does not ensure high quality of
the creative output.
·
The manics are often reckless and end up with self-injury.
Causes
Psychodynamic explanation: Feeling of loss that can be real or potential.
Hereditary factor: These disorders appear to be running in families.
The role of neurotransmitters: Serotonin and nor epinephrine have been found to be related to these
disorders.
Alterations in the level of these chemicals have a role to play in mood disorders
Behavioral explanation: Lack of, or reduction in, positive reinforcement leads to mood disorders.
Cognitive explanation: the sufferers of depression believe that they are life's losers; they are failures,
inadequate, and not meant to be the `winners' in life. They have a pessimistic view of life.
Evolutionary psychology explanation: Considering the impact of the genetic factors, it states that depression
is an adaptive response to unattainable goals.

one's thoughts being relayed to others who are out of physical reach.
Hallucinations and Perceptual Disorders
The schizophrenic has sensory experiences that ordinary people do not have.
They may hear voices, see people or objects, and/or smell things that others find to be non-existent.
The hallucinations mean reality to the schizophrenic.
Hallucinations are usually based on the delusions.
The sense of own body is also affected in schizophrenia.
