Mental health involves a balanced development of personal and emotional attitudes for harmonious living. Good mental health includes feelings of confidence, adaptability, acceptance of criticism, moral and social values, and good relationships.
Mental illness can be caused by nervous system damage, heredity, social/environmental factors, and prolonged emotional reactions like anxiety or fear. Some types of mental disorders are neurosis, personality disorders, amnesia, anxiety, depression, somnambulism, schizophrenia, manic depression, mood disorders, and attention deficit disorders.
Treatment for mental disorders includes shock therapy, psychotherapy, chemotherapy, and social therapy through attention and care from others.
