The article presents a study which examined the impact of anodal transcranial direct current stimulation (tDCS) on working memory performance of patients after a stroke. It found that anodal transcranial direct current stimulation can enhance the working memory of stroke patients by improving the correct response and error detection rates. It revealed that acquired brain damage following a stroke leads to chronic cognitive deficits which can affect the daily activities of the patients. Also, it explored the use of Phoresor PM850 in the application of anodal transcranial direct current stimulation.

Objective: This study aimed to demonstrate the incidence of altered level of consciousness after hemorrhagic stroke and identify factors associated with altered level of consciousness at 3 mos after stroke. Design: This study used data from a prospectivemulticenter cohort study conducted in nine hospitals in Korea and included 1677 patients with first-ever hemorrhagic stroke. Patients were dichotomized into those with and without altered level of consciousness at 3mos after stroke. Multivariate logistic regression analysiswas performed to identify factors associated with subacute to chronic stage altered level of consciousness. Results:Among patientswith hemorrhagic stroke (age: 20-99 yrs, female 50.21%), the prevalence of altered level of consciousness at admission was 38.58% (25.4% [drowsy], 6.38% [stupor], and 6.8% [coma]) and 17.29% 3 mos after stroke. Multivariate logistic regression analysis revealed that independent factors associated with altered level of consciousness at 3 mos after stroke included late seizure (odds ratio [95% confidence interval], 5.93 [1.78-20.00]), stroke progression (3.84 [1.48-9.64]), craniectomy (2.19 [1.19-4.00]), history of complications (1.74 [1.18-2.55]), age at stroke onset (1.08 [1.07-1.10]), and initial Glasgow Coma Scale score category (0.36 [0.30-0.44]). Conclusions: The factors associated with altered level of consciousness at 3 mos after stroke should be considered when explaining long-term consciousness status and focused management of modifiable factors in acute care hospitals could help ameliorate altered level of consciousness and promote recovery after stroke.

Objective: The aim of the study was to investigate the correlation between spasticity severity and functional outcomes during the first year after stroke. Design: The Korean Stroke Cohort for Functioning and Rehabilitation is a large, multicenter, prospective cohort study of all patients with acute first-ever stroke admitted to participating hospitals in nine Korean areas. To investigate the correlation between spasticity severity and functional status measured by using the Institutes of Health Stroke Scale (NIHSS), Modified Barthel Index (MBI), Functional IndependenceMeasurement (FIM), Fugl-Meyer Assessment (FMA), Functional Ambulatory Category (FAC), modified Rankin scale (mRS), and American Speech-Language Hearing Association National Outcome Measurement System Swallowing Scale (ASHA-NOMS), data were analyzed at 3, 6, and 12 mos after the occurrence of stroke. Results: A total of 7359 stroke patients, 3056 were finally included. Prevalence rates of spasticity in patients after stroke were 6.8% at 3 mos, 6.9% at 6 mos, and 7.6% at 12 mos. The scores of mRS and NIHSS were higher and those of K-MBI, FIM, FMA, and ASHA-NOMS were lower in more severe spastic patients, indicating poorer functional outcomes (P < 0.05). Conclusions: This study demonstrated the coexistence of spasticity and poor functional outcome during the first year after first-ever stroke patients. [ABSTRACT FROM AUTHOR]
