The affective spectrum is a spectrum of affective disorders (Mood disorders). It is a grouping of related psychiatric and medical disorders which may accompany bipolar, unipolar, and schizoaffective disorders at statistically higher rates than would normally be expected. These disorders are identified by a common positive response to the same types of pharmacologic treatments. They also aggregate strongly in families and may therefore share common heritable underlying physiologic anomalies.
Affective spectrum disorders include:
- Attention-deficit hyperactivity disorder
- Bipolar disorder
- Body dysmorphic disorder
- Bulimia nervosa and other eating disorders
- General anxiety disorder
- Irritable bowel syndrome
- Impulse-control disorders
- Major depressive disorder
- Narcolepsy
- Obsessive-compulsive disorder
- Oppositional-defiant disorder
- Panic disorder
- Posttraumatic stress disorder
- Premenstrual dysphoric disorder
- Social anxiety disorder
The following may also be part of the spectrum accompanying affective disorders.
- Chronic pain
- Intermittent explosive disorder
- Pathological gambling
- Personality disorder
- Substance abuse and addiction (includes alcoholism)
Many of the terms above overlap. The generally accepted definition of these terms can be found in the Diagnostic and Statistical Manual of Mental Disorders (DSM).
