MoCA was developed in a memory clinic setting and normed in a highly educated population. Executive functions, higher-level language abilities, and complex visuospatial processing can also be mildly impaired in MCI participants of various etiologies and are assessed by the MoCA with more numerous and demanding tasks than the MMSE.

The MoCA’s memory testing involves more words, fewer learning trials, and a longer delay before recall than the MMSE. There are several features in MoCA’s design that likely explain its superior sensitivity for detecting MCI. MoCA is also sensitive to detect cognitive impairment in cerebrovascular disease and Parkinson’s disease, Huntington’s disease, brain tumors, systemic lupus erythematosus, substance use disorders, idiopathic rapid eye movement sleep behaviour disorder, obstructive sleep apnoea, risk of falling, rehabilitation outcome, and epilepsy. MoCA’s sensitivity and specificity to detect subjects with MCI due to Alzheimer’s disease and distinguish them from healthy controls are excellent.

Its validity has been established to detect mild cognitive impairment in patients with Alzheimer’s disease and other pathologies in cognitively impaired subjects who scored in the normal range on the MMSE. It is a simple 10 minute paper and pencil test that assesses multiple cognitive domains including memory, language, executive functions, visuospatial skills, calculation, abstraction, attention, concentration, and orientation. All rights reserved.The Montreal Cognitive Assessment (MoCA) is a cognitive screening instrument developed to detect mild cognitive impairment (MCI). Our findings suggest that although the MoCA may be a useful screening tool post-stroke in detecting gross impairments, neuropsychological assessment is still necessary for a comprehensive and reliable detection of domain-specific cognitive deficits, which can more reliably inform us for realistic goal setting and vocational advice vital for effective rehabilitation.Ĭognition Cognitive assessment MoCA Neuropsychology Stroke Vascular disease.Ĭopyright © 2014 Elsevier B.V. In addition, a high proportion (up to 59%) of patients who scored the maximum points in one of the MoCA-specified domains were impaired on comparable neuropsychological assessment. The most common impairments were in general intelligence, information processing speed and visual memory three areas not assessed by the MoCA. Of these, 78% were found to be impaired (≤ 5%ile) on neuropsychological assessment in one or more cognitive domains. In this retrospective study, cognitive profiles for 136 acute stroke patients admitted to the Acute Stroke Unit who had available MoCA and neuropsychological assessment data were examined.Ģ2% of our patients were deemed cognitively intact on the MoCA. Our retrospective study examined the extent to which intact performance on the MoCA reflects intact cognition as determined by neuropsychological assessment. The Montreal Cognitive Assessment (MoCA) is an increasingly popular clinical screening tool for detecting cognitive impairment in stroke, but few studies have directly compared performance on the MoCA with neuropsychological assessment.
