“…4 From the previous study that traced patients with stroke during three months it was found that most patients have mild disability (57.2%), some have severe disability (18.6%), and a few have moderate disability (9.4%). 5 In addition, stroke also led to memory disturbance and dementia over 9.4 times compared with and without stroke, 6 memory disturbance between 20 -80 percentage, 7,8 and the incidence of dementia was 5-48 percentage. 3,4 Moreover, probability of recurrent stroke increased, 9,10 recurrent stroke was 33.3 percentage, 11 the mortality rate of dementia after stroking was three times compared with and without, 7 and the estimated cost of caring the dementia patients around the world is approximately 604,000 million US dollar.…”

Risk factors associated with post-stroke dementia: a systematic review and meta-analysis

This study aimed to evaluate the risk factors for prognostic of post-stroke dementia (PSD). A systematic review included case-control and/or cohort studies, we searched both published and unpublished literatures between 2000 to July 31, 2016. Two authors independently screened and selected research articles. If another one disagreed, the third author would be just along with his/her professionally. Moreover, Critical appraisal was measured by the quality (GRADE). Data collection was in the data extraction form. The Rev-Man 5.3 was used to estimate pooled data. The fixed-effect model will be used when the heterogeneity I² <50%, whereas the random-effects model will be used when the heterogeneity I²>50%. Result eight publications were pooled for measuring an association between risk factors and PSD by meta-analysis. There were 6 strongly PSD risk factors. The pooled relative ratio (RR) of atrial fibrillation was 1.68, previous stroke 1.59, myocardial infarction 1.40, hypertension 1.36, diabetes mellitus 1.25 and previous transient ischemic attack 1.25 respectively. Un-pooled data from 13 publications reported that the risk factors for dementia in stroke patients were i) demographic factors, ii) vascular risk factors, iii) stroke factors, iv) stroke complications, and v) abnormalities on brain imaging. Strongly risk factors associated with increasing PSD risk were atrial fibrillation, previous stroke, myocardial infarction, hypertension, diabetes mellitus, and previous transient ischemic attack. Further studies, strongly risk factors need to investigate and develop the risk score for the prediction of dementia in stroke patients.

Background and Purpose-There is some evidence that poststroke dementia, cognitive impairment no dementia (CIND), and mild cognitive impairment predict for poor outcomes such as dementia, death, and institutionalization. However, few studies have examined the prognostic value of CIND, CIND severity, and domain impairments in a poststroke cohort. Methods-A cohort of ischemic stroke patients with baseline cognitive assessments 3 months poststroke were followed up annually for outcomes of dependency, vascular events, and death for up to 5 years. Univariate and multivariate Cox proportional regression was performed to determine the ability CIND, CIND severity, and domain impairments to predict dependency, vascular outcomes, and death. Results-Four-hundred nineteen patients without dementia (mean age 60Ϯ11 years, 32% female) were followed for a mean of 3.2 years. Older age, diabetes, more severe strokes, CIND-mild, and CIND-moderate were independently predictive of dependency. There were no independent predictors of recurrent vascular events. Older age, diabetes, and CIND-moderate were independently predictive of death. In analyses of individual cognitive domains, impairments in visuomotor speed were independently predictive of dependency. Conclusions-In poststroke patients, CIND predicts dependency and death, while CIND severity discriminates patients with poor survival. Impairments in visuomotor speed independently predict dependency. Clinical Trial Registration-URL: http://clinicaltrials.gov. Unique Identifier: NCT00161070.(Stroke. 2011;42:883-888.)Key Words: dementia Ⅲ stroke Ⅲ mild cognitive impairment Ⅲ cognitive impairment no dementia D ementia, cognitive impairment no dementia (CIND), and mild cognitive impairment (MCI) have become increasingly prevalent in aging populations. CIND is a broad concept that has been used to define impairments in any objective cognitive domain in neuropsychological testing in the absence of dementia. 1 In community-based studies, CIND has been shown to predict for dementia, death, and institutionalization. 2 One study found that poststroke CIND is a negative predictor of survival. 3 Studies have also shown that poststroke dementia (PSD) increases the risk of recurrent vascular events. 4,5 However, no studies to date have examined the effect of CIND on poststroke recurrent vascular events or dependency. We hypothesize that CIND is associated with dependency, recurrent vascular events, and death following ischemic stroke.In a previous study from this cohort, 6 we have shown that CIND severity predicts incident dementia; CIND-mild patients shared a similar risk profile with patients with no cognitive impairment (NCI), and CIND-moderate patients experienced a 6-fold increase in the risk of incident dementia. Because PSD has been associated with recurrent vascular events 4 and death, 7 we hypothesize that a similar association may exist with CIND severity and outcomes after stroke.Previous studies that have examined the prognostic abilities of domain-specific impairments have found tha...

“…El deterioro cognitivo secundario a un ictus se asocia con una mayor mortalidad (Tatemichi et al, 1994), mayor tasa de institucionalización (Pasquini, Leys, Rousseaux, Pasquier, y Henon, 2007) y un aumento en los costes sanitarios (Claesson, Linden, Skoog, y Blomstrand, 2005). Reducir el impacto de la HVE en la capacidad funcional del paciente debe ser uno de los objetivos de la rehabilitación del ictus ya que influye directamente en su calidad de vida, así como la de sus cuidadores.…”

ResumenObjetivo: Realizar una revisión descriptiva sobre la heminegligencia visuo-espacial asociada a accidentes cerebro-vasculares. Se abordan los aspectos clínicos y teóricos más relevantes, así como las diferentes técnicas de intervención utilizadas actualmente. Desarrollo: La heminegligencia visuo-espacial es un déficit neuropsicológico multimodal asociado a lesiones cerebrales, principalmente de origen vascular. Su presencia implica una recuperación más lenta, mayor discapacidad y una respuesta precaria a la rehabilitación. Aunque la recuperación espontánea puede ocurrir en el transcurso de las primeras semanas o meses, el paso del tiempo no necesariamente implica una mejora de los síntomas. A día de hoy se han desarrollado múltiples estrategias de rehabilitación, pero son muy pocas las que demuestran efectos perdurables en el tiempo. Conclusiones: La adaptación de prismas es la técnica con la que se obtienen mejores resultados, aunque existen controversias respecto a sus beneficios a largo plazo. Las diferentes intervenciones que se describen en el artículo tienen un impacto transitorio y los resultados no acostumbran a traducirse en una mejora en las actividades de vida diaria. Las tendencias actuales apuestan por la aplicación combinada de diferentes técnicas.
