All personality disorders are difficult to treat, but the relevant means can help patients to conduct behavior modification, mainly as follows: 1, medication: general medication is difficult to change personality, so only a small amount of medication is used to help when there is an abnormal stressful event that leads to significant mood swings. If the patient is emotionally unstable, mood stabilizers or a small amount of antipsychotic drugs can be given; patients with aggressive behavior can be given a small amount of lithium carbonate, and use other mood stabilizers as appropriate; patients with anxiety can be treated with benzodiazepines. However, general drugs can only be applied in small amounts for a short period of time and are opposed to long-term use or routine use; 2. Psychotherapy: in-depth contact with the doctor is required and a good doctor-patient relationship is established, which then helps to recognize personality defects and encourages the patient to make efforts to change his or her behavior patterns, while other psychotherapy methods such as psychodynamic, cognitive therapy, behavior therapy and correction of bad habits can also be taken; 3. training and education: develop the patient’s ability to interact interpersonally. In addition to this, it is most important to develop a sound personality during the early years.
