Personality disorders are slightly different from other types of mental health issues. They tend to be more difficult to treat, though medication can sometimes be helpful depending on the case. With personality disorders, counseling and therapy are a much more integral part of treatment than medication. An individual's personality is the set of characteristics that set them apart from others, and it includes behaviors, feelings, and thoughts.
Personality disorders are patterns of behavior, emotion, and thought that last for long periods, cause mental distress or issues with functioning, and deviate from cultural expectations. There are ten types of personality disorder currently outlined in the DSM-V. A personality disorder must affect at least two of these: a person's way of viewing themselves and others, their emotional responses, their relationships with others, and their ability to control their behavior.
