Electroconvulsive Therapy among Elderly patients: A study from Tertiary care centre in north India.

OBJECTIVE: This retrospective study aimed to evaluate the effectiveness and safety of ECT among elderly patients receiving electroconvulsive therapy (ECT).

METHODS: During the study period of January 2008 to May 2017, 151 patients aged ≥60 years received ECT and they formed the study sample. Data on patients aged 19 to 59 years for the period of 3 years (2014-2016) was also extracted for comparison purposes.

RESULTS: The mean age of the elderly subjects was 65.8 years. In contrast to the young patients, elderly patients who received ECT more often had diagnosis of affective disorder, especially unipolar depression. Compared to young patients, elderly patients had higher prevalence of physical comorbidity with one third having more than one physical illness. The most common reason for use of ECT among elderly was poor response to medications (62.3%), followed by requirement of early response (49.6%). Four-fifth (80.8%) of the elderly patients showed ≥50% reduction in the symptoms with ECT. In terms of side effects, acute blood pressure changes were seen in 40.3% of patients during the ECT procedure and about half of the patients reported cognitive disturbances.

CONCLUSION: Present study suggests that ECT can be safely used among elderly patients, especially those with depressive disorders, not responding to medications.
