In vivo Prevalence of Alzheimer Biomarkers in Dementia with Lewy Bodies.

CONCLUSIONS: Reduction in Αβ42 in DLB may be more common (>80% of patients) than previously thought, and ∼40% may have the typical CSF AD biomarker profile. AD biochemistry in DLB may be an evolving process showing increasing frequency with disease progression. PMID: 31311013 [PubMed - as supplied by publisher]

In conclusion, recent research shows physical activity to be a promising intervention for the prevention and non-pharmacological treatment of dementia in that it contributes to the improvement of patients' quality of life. However, results vary according to the particularly characteristics of the exercise under review, such as type, intensity, frequency, and duration. It is therefore important to gain both awareness and understanding of the specific factors that give physical activity its therapeutic potential leading to the development of exercise programs designed specially to treat dementia.

Authors: Eldadah BA, Fazio EM, McLinden KA Abstract In this issue of Alzheimer's &Dementia, Mashour et al. propose the intriguing hypothesis that some manifestations of late-stage dementia are reversible, albeit transiently. Calling this phenomenon paradoxical lucidity, their paper follows a 2018 workshop sponsored by the National Institute on Aging that assessed the state of knowledge on lucidity in dementia and identified areas ripe for further study. The National Institute on Aging has since released two funding opportunity announcements (RFA-AG-20-016 and RFA-AG-20-017) to establish the building blocks of s...

Authors: Wanleenuwat P, Iwanowski P, Kozubski W Abstract Alzheimer's disease (AD) is the most common form of dementia manifesting as alterations in cognitive abilities, behavior and deterioration in memory which is progressive, leading to gradual worsening of symptoms. Major pathological features of AD are accumulations of neuronal amyloid plaques and neurofibrillary tangles, with early lesions appearing primarily in the hippocampus, the area of the brain involved in memory and learning. Cardiovascular related risk factors are believed to play a crucial role in disease development and the acceleration of cognitive ...

AbstractAlthough cognitive and functional impairment are the hallmark features of Alzheimer ’s disease (AD), neuropsychiatric symptoms associated with AD account for increased rates of disability and profoundly impact the quality of life of both patients and their caregivers. This narrative review of current evidence provides practical guidance in diagnosing and managing depression in pa tients with AD using pharmacological and nonpharmacological interventions. After apathy, depression is the second most common neuropsychiatric symptom in AD. Diagnosing late-life depression (LLD), particularly in those affected by AD...

Dysfunction of the blood-brain barrier, allowing molecules and cells not normally present in the central nervous system to enter, is one of the features of dementia. If nothing else, this causes inflammation in the brain as the immune system is roused to try to clear out the unwanted materials. Chronic inflammation in the immune cells of the central nervous system is an important part of the progression of neurodegenerative conditions, and in Alzheimer's disease shows up after the initial accumulation of amyloid-β. This sequence of events may be due in part to amyloid-β causing blood-brain barrier dysfunction, th...
