Symptoms and Diagnosis

People with borderline personality disorder are unsure of their identity, which affects how they feel about themselves, relate to others, and behave. Common symptoms of borderline personality disorder include impulsive, risky, or destructive behavior, episodes of intense anxiety or depression, difficulty controlling emotions, and feelings of self-hate. These behaviors can lead to unstable jobs, friendships, and values. People with this disorder often have dramatically shifting views of others, which can harm their relationships. Due to risky and impulsive actions, people with borderline personality disorder are more vulnerable to pregnancies, sexually transmitted diseases, accidents, and physical violence.

Borderline personality disorder is typically diagnosed in adults because similar signs of the disorder in children often disappear by adulthood. A diagnosis of borderline personality disorder is determined through a psychological evaluation, assessment of medical history and symptoms, and criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM).

Many professionals find diagnosing borderline personality disorder difficult since these criteria could apply to several mental conditions, such as mood and anxiety disorders.
