“…For instance, the MMSE is a brief test with extensive international usage; however, several studies have mentioned that the MMSE alone can be used in a sensitive test to detect cognitive impairment, except if cutoff is increased or combined with other neuropsychological tests 51,52. Therefore, the MMSE was used with MoCA and ACE-R to detect MCI because the last two assessments are used to assess early stages of dementia and executive function, as well as identify frontal subcortical infarction 50,53,54. In addition, ACE-R has good sensitivity for dementia, whereas MoCA is specifically used in MCI screening.…”

Cognitive impairment and memory dysfunction following stroke diagnosis are common symptoms that significantly affect the survivors’ quality of life. Stroke patients have a high potential to develop dementia within the first year of stroke onset. Currently, efforts are being exerted to assess stroke effects on the brain, particularly in the early stages. Numerous neuropsychological assessments are being used to evaluate and differentiate cognitive impairment and dementia following stroke. This article focuses on the role of available neuropsychological assessments in detection of dementia and memory loss after stroke. This review starts with stroke types and risk factors associated with dementia development, followed by a brief description of stroke diagnosis criteria and the effects of stroke on the brain that lead to cognitive impairment and end with memory loss. This review aims to combine available neuropsychological assessments to develop a post-stroke memory assessment (PSMA) scheme based on the most recognized and available studies. The proposed PSMA is expected to assess different types of memory functionalities that are related to different parts of the brain according to stroke location. An optimal therapeutic program that would help stroke patients enjoy additional years with higher quality of life is presented.

IntroductionThe Stroke and Cognition consortium (STROKOG) aims to facilitate a better understanding of the determinants of vascular contributions to cognitive disorders and help improve the diagnosis and treatment of vascular cognitive disorders (VCD).MethodsLongitudinal studies with ≥75 participants who had suffered or were at risk of stroke or TIA and which evaluated cognitive function were invited to join STROKOG. The consortium will facilitate projects investigating rates and patterns of cognitive decline, risk factors for VCD, and biomarkers of vascular dementia.ResultsCurrently, STROKOG includes 25 (21 published) studies, with 12,092 participants from five continents. The duration of follow-up ranges from 3 months to 21 years.DiscussionAlthough data harmonization will be a key challenge, STROKOG is in a unique position to reuse and combine international cohort data and fully explore patient level characteristics and outcomes. STROKOG could potentially transform our understanding of VCD and have a worldwide impact on promoting better vascular cognitive outcomes.

“…Consistent with this hypothesis, patients with stroke [16,22] or with occlusion/stenosis of the ICA [35] are more likely to lose points on items from the visuospatial/executive, fluency and recall subtests than on items from other subtests. These are also the items on which patients with post-stroke cognitive impairment perform worse than stroke patients without cognitive impairment [14,19]. However, it must be noted that these items are the most difficult questions on the MoCA test [43] and are the items that even a neurologically healthy person is more likely to fail (see link to Supplemental Data from healthy controls at www.mocatest.org).…”

Validity and Applications of the Montreal Cognitive Assessment for the Assessment of Vascular Cognitive Impairment

Cognitive impairment is common among patients with stroke or other cerebrovascular disease and influences long-term outcome, including occupational functioning. Recognition and monitoring of mild cognitive impairment is thus essential to good patient care. The Montreal Cognitive Assessment (MoCA) has been suggested as a brief screening test of vascular cognitive impairment. This paper presents a critical review of the research literature evaluating the validity and utility of this test with the aim of informing future clinical and research practice. A total of 30 papers employing the MoCA in the context of cerebrovascular disease were identified. Reporting of the methods and results of such studies tended to fall short of the established reporting guidelines. Under-specification of the exclusion criteria applied and their impact make it difficult to assess the potential impact of sampling bias and loss to follow-up. Nevertheless, content validity evidence suggests that the MoCA covers most of the domains that represent cognitive impairment in cerebrovascular disease, with mixed evidence for its preferential sensitivity to the type of cognitive impairment encountered in the context of vascular disease. Evidence clearly supports the need to establish norms and cut-offs for the MoCA that are culturally appropriate and that are matched to the range of cognitive impairment that is present in the population being assessed. Recent modifications of the MoCA have been developed for assessing patients with visual impairment or restricted mobility, which may reduce the impact of ‘untestability' on cognitive screening in the clinic or research context. The MoCA correlates well with other measures of cognitive and functional abilities in patients with cerebrovascular disease, and may also predict future response to rehabilitation and long-term occupational outcome. Further research is needed to provide evidence for the validity of the MoCA in longitudinal studies. However, it compares favourably to the Mini Mental State Examination as a screening test that is sensitive to the milder forms of cognitive impairment that often accompany cerebrovascular disease.
