Schizoaffective disorder has features that resemble both Schizophrenia and Mood (affective) Symptoms.
A person who has Schizoaffective Disorder will experience delusions, hallucinations, other symptoms that are characteristic of schizophrenia and significant disturbances in their mood.
People who experience more than two weeks of psychotic symptoms in the absence of severe mood disturbances—and then have symptoms of either Depression or Bipolar Disorder—may have Schizoaffective Disorder.
Depressive symptoms associated with Schizoaffective disorder can include—but are not limited to—
- disrupted appetite
- disturbed sleep
- inability to concentrate,
- depressed mood (with or without suicidal thoughts).
Manic (Bipolar) symptoms associated with Schizoaffective Disorder can include —
- increased energy
- decreased sleep (or decreased need for sleep)
- fast (“pressured”) speech
- increased impulsive behaviors (e.g., sexual activities, drug and alcohol abuse, gambling or spending large amounts of money)
Sometimes people with other mental illnesses including Borderline Personality Disorder may also be incorrectly diagnosed with Schizoaffective Disorder.
Evidence exists for abnormalities in the metabolism of Tetrahydrobiopterin (BH4), Dopamine, and Glutamate in people with Schizophrenia and Schizoaffective Disorders.
