A mental illness is illness within the bounds of mental health that is clinically recognisable by symptoms and behaviours. Mental illnesses disrupt normal functioning of the person either cognitively, emotionally, biologically, etc. This includes such illnesses as depression, eating disorders (anorexia, bulimia, binge eating), obsessive compulsive disorder, Bipolar disorder, schizophrenia, personality disorders (anti-social personality, borderline personality, etc.), psychotic disorders, trichotillomania (recurrent pulling of hair), psychological sexual disorders, etc. There are far too many to mention all of them.
Diagnosis is usually made by guidelines set out by the Diagnostic and Statistical Manual of Mental Disorders, DSM-IV (IV because it is the 4th edition of the publication), published by the American Psychiatric Association in 1994. An updated version of the manual, DSM-IV-TR (TR for text revision), was published in 2000.
Initial diagnosis of a mental illness may be made by a medical practioner who may recommend medication or refer the patient to a psychologist or psychiatrist, depending on the illness diagnosed.
