Answer and Explanation: True. Borderline personality disorder is characterized by unstable moods, behaviors, and having difficulty forming trusting and stable relationships. However, this disorder has no direct causes, though there are numerous risk factors for the disease such as a genetic predisposition and an unstable childhood.
Because the cause of borderline personality disorder hasn't been linked to one specific biological factor, it would be difficult to create a pharmaceutical treatment for the disorder. Thus, there are currently no approved treatments for borderline personality disorder.
