What Are the Signs of a Mental Health Disorder?

Mental health disorders exist in broad categories: anxiety disorders, mood disorders, psychotic disorders, personality disorders and impulse control disorders. If someone you know experiences erratic thought patterns, unexplained changes in mood, lack of interest in socializing, lack of empathy, inability to tell the difference between reality and fantasy, or a seeming lack of control, that person may have a mental health disorder. This is, by no means, a complete list of symptoms.
