This study found that Electroconvulsive Therapy (ECT) has a significant impact on plasma BDNF levels in patients with resistant schizophrenia, increasing BDNF levels and improving symptoms. Patients in both groups showed significant improvement in PANSS subscales after ECT treatment.
Objectives The study aimed to assess the effect of Electroconvulsive Therapy (ECT) on plasma BDNF levels in patients with resistant schizophrenia. Methods It was a cohort study that included 60 patients with resistant schizophrenia fulfilling the DSM-5 criteria of schizophrenia and APA criteria of resistant schizophrenia. They were divided into two groups, followed over 4 weeks, and compared to their baseline assessment. Group (A) included 45 patients who received 4-10 sessions of ECT while Group (B) included 15 patients who received the usual treatment with antipsychotics without ECT. The assessment included the severity of psychotic symptoms assessed by the Positive and Negative Symptom Scale (PANSS) in addition to plasma BDNF level. Results Patients in Group (A) had an increased level of BDNF after treatment with a statistically significant difference in comparison to their baseline BDNF level (P = 0.027). Meanwhile, patients in group (B) showed a non-significant increase in BDNF. Patients in both groups improved significantly in all PANSS subscales after treatment. Conclusions It was concluded that plasma BDNF levels in patients with resistant schizophrenia increase after electroconvulsive therapy in association with clinical improvement.
