Introduction
Borderline personality disorder (BPD) is a complex psychiatric and psychological condition characterized primarily by emotional instability, turbulent interpersonal relationships, unclear self-identity, and impulsive behaviors. It typically emerges in early adulthood and significantly impacts patients' quality of life. If persistent emotional dysregulation, self-harming behaviors, or severe interpersonal conflicts occur, prompt medical evaluation is recommended.

It typically emerges in early adulthood. If persistent emotional dysregulation, self-harming behaviors, or severe interpersonal conflicts occur, prompt medical evaluation is recommended.
The exact cause of BPD remains incompletely understood but may involve genetic factors, childhood trauma, and imbalances in brain neurotransmitters. Key symptoms include intense emotional fluctuations, with frequent episodes of anger, anxiety, or depression; extreme and unstable relationships marked by alternating idealization and devaluation; disturbances in self-identity; and impulsive actions such as self-injury or binge eating.
Treatment primarily involves psychotherapy, with approaches such as dialectical behavior therapy (DBT) and cognitive behavioral therapy (CBT) commonly used to help patients regulate emotions and improve interpersonal functioning. Medication may be added when necessary to alleviate associated symptoms like anxiety or depression, but must be prescribed and monitored by qualified healthcare professionals.
Nursing care should provide consistent support while maintaining clear boundaries, avoiding both excessive criticism and permissiveness. Patients should be encouraged to engage in structured daily activities and develop effective emotion regulation skills. Communication should remain gentle and patient, helping individuals gradually modify maladaptive behavioral and cognitive patterns.
