“…1 Given the high prevalence of vascular risk factors in these patients, we hypothesize that nonadherence to medical therapy will likely lead to increased cardiovascular morbidity, These results are consistent with other data showing that a significant percentage of patients with carotid atherosclerosis have cognitive impairment. 4 Also in agreement with prior studies is the range of abnormal MoCA values observed, which is compatible with mild cognitive impairment. 7 Previously reported rates of cognitive impairment in carotid stenosis vary according to the specific cognitive testing utilized.…”

“…3 Carotid disease is a risk factor for cognitive impairment, with the underlying mechanism attributed to either cerebral emboli or hypoperfusion with or without silent brain infarctions. 4 We explored whether undiagnosed cognitive impairment impacts adherence to medications for vascular risk reduction in patients with asymptomatic carotid stenosis.…”

“…In addition, in the absence of collateral circulation, the brain is in a hypoperfusion state, which may cause ischemia in the region supplied by the deep perforating artery, inducing oxidative stress, inflammatory reaction, increased phagocytosis of oligodendrocytes, and metalloproteinase activation [20], which may reduce cognitive function. Patients with cerebral artery stenosis develop cognitive dysfunction to various degrees [21,22]. When the stenosis is improved and the perfusion increases, the cellular metabolism also improves [23].…”

BackgroundWe aimed to investigate cognitive function and affective disorder in elderly patients with symptomatic vertebrobasilar artery stenosis (SVAS) after stent-assisted angioplasty (SAA) and to explore the potential mechanism.Material/MethodsThe study subjects were 26 elderly SVAS patients who were non-responsive to pharmacotherapy and received SAA (study group) and 30 patients receiving intracoronary stent implantation (control group). Montreal cognitive assessment (MoCA), Hamilton depression rating scale (HAMD), and Hamilton anxiety rating scale (HAMA) were used.ResultsThe total MoCA score, scores of line connection, copying cube, drawing clock, and delayed recall increased significantly in the study group after surgery (P<0.05, P<0.01). In addition, the MoCA score increased over time and the total MoCA score at 12 months was markedly higher than that at 1 month (P<0.05). The scores of HAMD and HAMA decreased dramatically after surgery compared with before surgery in these patients (P<0.01). A comparison at the corresponding period was performed between study group and control group, and it was found that the differences in total MoCA scores and scores of line connection, copying cube, drawing clock, and delayed recall before surgery and at 1 month after surgery were significant (P<0.05, P<0.01).ConclusionsSAA may improve the visuospatial/executive abilities and delayed recall, as well as the depression and anxiety in patients with SVAS. Larger and controlled trails are needed to investigate the effect of SAA on cognition and affection in these patients.

“…Laboratory testing is the next step; at this stage, blood tests are used to determine the blood sugar level and cholesterol level. This step is followed by an examination of the computer tomography/magnetic resonance imaging scan and electrocardiography recording to indicate stroke location and pulse irregularity, such as cardiovascular status, carotid bruits, fundus examination, peripheral vascular disease, and hypertension 9. Electroencephalography is used to help differentiate between seizure and TIA or between lacunar and cortical infarction in occasional patients, as illustrated in Figure 2 10…”

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.
