Personality disorders are mental health conditions where a person's patterns of thinking, feeling, and behaving significantly differ from what's considered typical or healthy. These patterns are deeply ingrained and can cause problems in relationships, work, and daily life. There are different types of personality disorders, each with its own set of symptoms and characteristics. Some common ones include borderline personality disorder, narcissistic personality disorder, and antisocial personality disorder. Treatment often involves therapy to help manage symptoms and improve functioning in various areas of life.
