Dissociative Model in Patients With Resistant Schizophrenia

Area of Science:

• Psychiatry
• Clinical Psychology

Background:

• Schizophrenia affects 30-50% of patients, who remain resistant to antipsychotic treatments.
• Dissociative symptoms, characterized by a loss of integrity between memories and reality, are observed in schizophrenia patients.
• The variability in dissociation severity in schizophrenia patients necessitates investigating its link to treatment resistance.

Purpose of the Study:

• To investigate the correlation between the degree of dissociation and resistance to antipsychotic therapy in schizophrenia patients.
• To compare dissociation levels in schizophrenia patients with resistant illness versus those in clinical remission.

Main Methods:

• A correlational analysis was conducted on 106 schizophrenia patients (45 resistant, 60 in remission).
• Clinical symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS).
• Dissociative symptoms were evaluated using the Scale for Dissociative Experiences (DES).

Main Results:

• Patients with resistant schizophrenia exhibited significantly higher levels of dissociation compared to those in remission.
• The dissociation levels in resistant schizophrenia patients were more than double those in the remission group.
• Dissociation scores in resistant schizophrenia patients approached those seen in dissociative personality disorder.

Conclusions:

• Higher dissociation levels are strongly associated with antipsychotic resistance in schizophrenia.
• These findings suggest dissociation may be a crucial factor in treatment resistance.
• Exploring therapeutic strategies beyond antipsychotics and earlier diagnostic interventions are warranted for patients with high dissociation.
