Background: The sequelae of stroke include both physical and cognitive impairment. However, the physical impairment usually takes center-stage during rehabilitation, while cognitive impairment is largely ignored. Cognitive deficit is very common following stroke and its assessment and identification is crucial as it impacts on the outcome and rehabilitation of stroke survivors. Very few studies have explored any relationship between cognitive impairment and quality of life after stroke and these studies have been inconclusive. This study set out to explore any relationship that might exist between post-stroke cognitive impairment and quality of life of the survivors.
Methods: A descriptive cross-sectional study was conducted at the Stroke unit of the Korle Bu teaching hospital during which 110 stroke survivors were recruited. A structured questionnaire was used to obtain the demographic, clinical characteristics and risk factor profile of the study participants. The HRQOLISP-26 questionnaire which is a stroke specific quality of life scale was used to assess the QoL in this study while the Montreal Cognitive Assessment Scale (MoCA) was used to assess cognitive deficit.
Results: Mean age of the 110 study participants was 61±17 years. Presence of cognitive impairment after 3 months was associated with lower quality of life (p=0.003) while increasing age and level of education were associated with lower scores on MoCA scale (p=0.019, p=0.048 respectively).
Conclusion: Cognitive impairment is strongly associated with poor quality of life following stroke, therefore, cognitive rehabilitation (and not just physiotherapy) should be considered as an integral component in the management of stroke survivors.

Cognitive impairment (CI) in multiple sclerosis (MS) is only partially explained by whole-brain volume measures, but independent component analysis (ICA) can extract regional patterns of damage in grey matter (GM) or white matter (WM) that have proven more closely associated with CI. Pathology in GM and WM occurs in parallel, and so patterns can span both. This study assessed whether joint-ICA of GM and WM features better explained cognitive function compared to single-tissue ICA.

Alzheimer's disease is a complex neurodegenerative disease characterized by progressive decline in cognitive function and behaviour. Ginger is the rhizome of the plant Zingiber officinale Roscoe, has been an important ingredient of many Ayurveda formulations to treat neurological disorders. The present study aims to estimate the variation of 6-gingerol content in nine different ginger samples collected from Manipur, India, investigate the neuroprotective potential of the most potent ginger sample against scopolamine-induced cognitively impaired mice, and validate the therapeutic claim by molecular docking analysis.

Background: Temporal lobe epilepsy with isolated amygdala enlargement (TLE-AE) still lacks a definite characterization and controversies exist.
Methods: We conducted a retrospective study identifying brain MRI scans with isolated AE between 2015 and 2021. We collected clinical and paraclinical data of patients with TLE-AE and evaluated the outcome.
Predicting ALS informant distress from cognitive and behavioural change in people with ALS.

Background: The cognitive and behavioural changes that occur in around 50% of people with amyotrophic lateral sclerosis (ALS) may significantly affect people around them, contributing to heightened burden, anxiety, and depression. Despite existing evidence linking behavioural impairment to caregiver distress, the role of cognitive impairment remains less clear, with mixed findings on its impact.
Methods: This study assessed the influence of cognitive and behavioural impairments in people with ALS on the distress of their nominated informants.

Background: Skeletal and cardiac muscle damage have been increasingly recognized in female carriers of DMD pathogenic variants (DMDc). Little is known about cognitive impairment in these women or whether they have structural brain damage.
Objective: To characterize the cognitive profile in a Brazilian cohort of DMDc and determine whether they have structural brain abnormalities using multimodal MRI.
