Affective spectrum

src: cdn.shopify.com

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
Cataplexy
Dysthymia
Generalized anxiety disorder
Hypersexuality
Irritable bowel syndrome
Impulse-control disorders
Kleptomania
Migraine
Major depressive disorder
Obsessive-compulsive disorder
Oppositional defiant disorder
Panic disorder
Posttraumatic stress disorder
Premenstrual dysphoric disorder
Social anxiety disorder
Fibromyalgia

The following may also be part of the spectrum accompanying affective disorders.

Chronic pain
Intermittent explosive disorder
Pathological gambling
Personality disorder
Pyromania
Substance abuse and addiction (includes alcoholism)
Trichotillomania

Also, there are now studies linking heart disease.

Many of the terms above overlap. The American Psychiatric Association's definitions of these terms can be found in the Diagnostic and Statistical Manual of Mental Disorders (DSM).
