Subjective Memory Complaints and Sensitivity of the Subjective Memory Complaint Questionnaire in Post-Stroke Dementia Patients

Abstract

<b><i>Introduction:</i></b> Subjective memory complaints (SMCs) among stroke patients are common. To date, reports on SMCs using the Subjective Memory Complaint Questionnaire (SMCQ) are limited. We provided descriptive information on SMCs using the SMCQ alongside objective neuropsychological function assessment in stroke patients and established the sensitivity of SMCQ for post-stroke dementia. <b><i>Methods:</i></b> In total, 419 consecutive stroke patients who were admitted to a stroke unit for younger populations (age &#x3c;65 years) at a rehabilitation hospital from June 1, 2014, to January 1, 2020, were reviewed. SMCs were measured using the SMCQ. Objective neuropsychological function was assessed using protocols of the Vascular Cognitive Impairment Harmonization Standards. <b><i>Results:</i></b> SMCs were significantly correlated with objective neuropsychological functions including memory, executive function, language, and depression. SMCs were not significantly correlated with visuospatial function. The SMCQ exhibited comparable sensitivity to that of Mini-Mental Status Examination for evaluating post-stroke dementia. <b><i>Conclusions:</i></b> The SMCQ may be a valid measure of cognitive function among patients with stroke, is sensitive for post-stroke dementia, and may assume a complementary role for assessing patients with stroke.
