What are the classes of mental health disorders? 2. Why are they referred to as organic mental health disorders

The major classes of mental health disorders include neurodevelopmental disorders, schizophrenia spectrum and other psychotic disorders, bipolar and related disorders, depressive disorders, anxiety disorders, obsessive-compulsive and related disorders, trauma- and stressor-related disorders, dissociative disorders, somatic symptom and related disorders, feeding and eating disorders, sleep-wake disorders, sexual dysfunctions, gender dysphoria, disruptive, impulse-control, and conduct disorders, substance-related and addictive disorders, neurocognitive disorders, and personality disorders.

Organic mental health disorders are referred to as such because they are caused by a physical disease or injury affecting the brain. This means there is an identifiable biological or physiological cause, such as a brain tumor, infection, head trauma, stroke, or substance abuse, that directly leads to the mental health symptoms.
