| Abstract: | ObjectivesThis study explores the association between baseline impaired global cognitive function and changes in global cognitive function and depression among geriatric patients undergoing acute course electroconvulsive therapy (ECT).DesignRetrospective cohort study.SettingSingle freestanding psychiatric hospital.ParticipantsPatients aged 50 and older receiving ECT.Interventions10 ECT treatments.MeasurementsCognitive assessments with the Montreal Cognitive Assessment (MoCA). Depression assessment with the Quick Inventory of Depressive Symptomatology Self Report 16 item scale (QIDS).ResultsBaseline and follow-up data were available for 684 patients. On average, patients with baseline normal cognition (MoCA ≥26; N = 371) had a decrease in MoCA of -1.44±0.26 points over the course of treatment, while those with baseline impaired global cognitive function (MoCA <26; N = 313) had an increase in MoCA of 1.72±0.25 points. Baseline cognitive status was not associated with a differential response on the QIDS.ConclusionsPatients with baseline impaired global cognitive function did not demonstrate a worsening in cognition following ECT, and baseline global cognitive function was not associated with a differential change in depression with ECT. These results suggest that impaired global cognitive function should not be viewed as a contraindication to ECT in geriatric patients. |
