-
Vitamins and minerals play multiple functions within the central nervous system which may help to maintain brain health and optimal cognitive functioning.
Why it matters
This review evaluated whether vitamin and mineral supplements affect cognitive function in cognitively healthy people aged 40 or older. The provided text does not report the findings, so it is unknown whether supplementation helps maintain cognition or prevents dementia.
-
Modifiable lifestyle risk factors have been identified as playing a major role in the development of dementia; hence, interventions addressing these risk factors represent a significant opportunity to reduce the number of people developing dementia.
-
MoCA was administered to 274 patients from 2 prospective hospital-based cohort studies in Germany (n = 125) and France (n = 149).
Why it matters
This cohort study examined whether the Montreal Cognitive Assessment given within 7 days after stroke predicts long-term cognitive and functional outcome and mortality in 274 patients. It is about predicting outcomes after stroke and does not test any treatment, cure, or prevention for Alzheimer's disease.
-
Twelve studies with 195 PwD and four with 53 PwMCI met the inclusion criteria.
-
Quality of life of people with advanced dementia living in nursing homes is often suboptimal.
-
Technology-based cognitive training and rehabilitation interventions show promise, but the findings were inconsistent due to the variations in study design.
-
69/100
The survival prediction model demonstrated moderate accuracy for predicting mortality at 6 and 12 months before death in elderly patients with dementia.
-
CrExp therapy has greater positive effects on cognitive functions and daily living ability than standard cognitive training.
-
There is a lack of high-quality research in this field.
-
The potential determinants of cognitive decline identified in this study, in particular modifiable risk factors, should be tested in the context of randomised controlled trials.
Why it matters
In over 10,000 older people followed for 8 years, women showed less cognitive decline than men, and poor physical function, physical inactivity and smoking were linked to faster decline in some cognitive domains. The study describes factors associated with cognitive decline but does not test any treatment or cure for Alzheimer's disease.
-
There were 1 561 940 patients, including 17 963 hospitalized for ruptured AAA, 304 980 for AMI, 1 181 648 for stroke, 19 675 for aortic dissection, and 37 674 for SAH.
-
The plush toy used in this study offered marginally greater value for money than PARO in improving agitation.
Why it matters
This randomized controlled trial found no statistically significant between-group differences in agitation levels after using PARO, a plush toy, or usual care. PARO was $50.47 more expensive per resident than usual care, so it did not show a significant benefit for reducing agitation.
-
Long-term adherence to the MIND diet was moderately associated with better verbal memory in later life.
-
Patients with dementia are significantly more likely to be disenrolled from hospice following a long enrollment period compared with patients without dementia.
-
As aging is associated with cognitive decline, particularly in the executive functions, it is essential to effectively improve cognition in older adults.
-
Preliminary findings of our pilot study suggested that cognitive decline in psychomotor speed and executive function is possibly prevented by intradialytic CT and ET.
-
Our results suggest that adherence to the MeDi is associated with better cognitive performance and lower dementia rates in Greek elders.
Why it matters
This longitudinal study found that each unit increase in the Mediterranean dietary score was associated with a lower likelihood of dementia and better performance in some cognitive domains. The findings support the Mediterranean diet as potentially protective against cognitive decline in a Greek population.
-
Our findings suggest that older patients with reduced preoperative cognitive functions or who develop postoperative delirium are at risk of developing dementia within 5 years after cardiac surgery.
-
Risk of dementia, especially vascular or mixed dementia, may be increased with high SUA levels in elderly people.
-
There is a dearth of good-quality evidence investigating the cancer-dementia prevalence and its implications for successful cancer treatment.
-
Of all studies included in this systematic review, results from the highest quality studies, which were two randomized controlled trials, demonstrated that multi-domain CCT could lead to increases in hippocampal functional connectivity.
-
Depression is an accepted risk factor for dementia, but it is unclear if this relationship is causal.
-
69/100
Use of VR in hospitalized patients significantly reduces pain versus a control distraction condition.
-
Elderly patients with a hip fracture are vulnerable for delirium, especially when the patient has dementia.
-
Lifestyle for Brain Health (LIBRA) may help in identifying and monitoring risk status in dementia-prevention programmes, by targeting modifiable, lifestyle-related risk factors.
Why it matters
In 949 adults aged 50-81 from the Maastricht Ageing Study, followed for up to 16 years, each one-point rise in the LIBRA lifestyle-risk score was linked to a 19% higher risk of dementia and a 9% higher risk of cognitive impairment. The score predicted faster slowing of processing speed, but not decline in memory or executive function. The authors say it "may help in identifying and monitoring risk status" in prevention programmes. The study did not test whether changing these lifestyle factors lowers risk.
