Background:
Monitoring for cognitive deficits during a course of electroconvulsive therapy (ECT) is recommended, but cognitive assessment can be time consuming. The Audio Recorded Cognitive Screen (ARCS) is a cognitive test instrument with good psychometric properties that places minimal demands on clinicians' time, but until now, it has not been formally evaluated for monitoring cognition in the context of ECT treatment.
Objectives:
This study aimed to assess the feasibility/utility of using the ARCS in the assessment of depressed patients undergoing ECT.
Methods:
Depressed patients undergoing ECT were tested with the ARCS and a comparison instrument, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), in counterbalance order immediately before any ECT and after the sixth ECT treatment episode. Apathy (Apathy Scale) and depression (Profile of Mood states Short Form) were measured on both occasions. Analyses compared performances on the 2 cognitive instruments and examined for associations with the measures of apathy or depression.
Results:
Twenty-eight individuals (9 male, 19 female) aged 19 to 84 years underwent testing. Performances on the total ARCS were similar to those on the total RBANS, and both showed decline from baseline to follow-up. The total ARCS and RBANS measures correlated well (r = 0.75, P < 0.001). Neither apathy nor depression scores were significantly associated with scores on either the RBANS or ARCS.
Conclusions:
The ARCS was acceptable and convenient in the assessment of cognition in patients undergoing treatment with ECT. In light of its practical advantages, further evaluation of the ARCS for detecting cognitive impairment and tracking cognitive changes during ECT seems warranted.
