What is dual personality

Dual personality generally refers to dissociative identity disorder, which is a type of psychological disorder characterized by individuals having two or more distinct personality states, each with independent memory, behavioral patterns, and identity recognition. Dissociative identity disorder may be related to childhood trauma, long-term stress, genetic factors, abnormal brain function, and overactivation of psychological defense mechanisms.

1. Childhood trauma

Severe traumas such as physical abuse, sexual abuse, or emotional neglect during childhood may lead individuals to cope with unbearable pain by using split personality as a psychological defense mechanism. Patients may exhibit sudden switching of personality states, accompanied by memory loss or fragmented recollection. Treatment should be combined with long-term psychological therapy such as trauma focused cognitive-behavioral therapy, and if necessary, antidepressants such as sertraline hydrochloride tablets and escitalopram oxalate tablets should be used as prescribed to assist in stabilizing emotions.

2. Long term stress

Continuous exposure to extreme situations such as war, disaster, or domestic violence may trigger personality separation as an adaptive response. Patients with different personalities may exhibit completely opposite personality traits, and switching is often accompanied by headaches or distorted time perception. Intervention measures include stress management training, mindfulness therapy, and in severe cases, short-term use of olanzapine tablets can be used to control symptoms of loss of realism.

3. Genetic factors

Individuals with a history of schizophrenia or dissociative disorders in the SEP family have an increased risk of developing the disease, which may be related to the influence of specific genes on the default mode network function of the brain. These patients often experience personality transition during adolescence, accompanied by hallucinations or somatic symptoms. Genetic testing combined with neuroimaging evaluation is required, and second-generation antipsychotic drugs such as quetiapine fumarate tablets are used in combination with home treatment for treatment.

4. Abnormal brain function

Abnormal functional connectivity in the temporal or prefrontal cortex may lead to cognitive integration disorders, manifested as significant waveform changes in the electroencephalogram during personality transition. The patient may describe their body as being controlled by others, accompanied by non epileptic seizures. Repeated transcranial magnetic stimulation therapy, combined with sodium valproate sustained-release tablets to regulate nerve excitability, is required after neurological evaluation.

5. Excessive psychological defense

Individuals who use dissociation mechanisms for a long time to cope with daily stress may develop pathological personality separation. Manifested as a sense of unfamiliarity with one's own behavior or the discovery of unfamiliar objects, but without a complete second personality. The treatment focuses on cultivating emotional regulation ability through dialectical behavior therapy and assisting paroxetine hydrochloride tablets in improving accompanying anxiety symptoms. Patients with dissociative identity disorder need to establish a stable treatment alliance, and family members should avoid questioning the authenticity of the patient's experience. They can assist in recording personality switching triggering factors. Maintain a regular daily routine, limit caffeine intake, and improve body perception through low-intensity exercises such as yoga. When there is a tendency towards self harm or a severe sense of reality disorder, immediate medical attention should be sought and medication dosage should not be adjusted on one's own.
