Amyloid Fibrils

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Alzheimer's Disease: Treatment

Alzheimer's Disease: Treatment

Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Summary

Adequate daily fluid intake may be crucial for brain health in older adults. Lower hydration levels were linked to increased Alzheimer's disease (ADRD) biomarkers like Aβ deposition and cerebrovascular injury.

Area of Science:

Gerontology
Neurology
Neuroscience

Background:

Older adults are at higher risk of dehydration.
The link between hydration status and Alzheimer's disease and related dementias (ADRD) is understudied.
Fluid intake may impact cognitive health and brain aging.

Purpose of the Study:

To investigate the association between daily fluid intake and neuroimaging biomarkers of ADRD in cognitively normal older adults.
To explore hydration's potential role in ADRD pathogenesis.

Main Methods:

Cross-sectional study analyzing daily fluid intake and neuroimaging data (Aβ deposition, cerebrovascular injury).
Participants were 287 cognitively normal older adults.
Statistical analysis to determine correlations between fluid intake and biomarkers.

Main Results:

Lower daily fluid intake was significantly associated with greater brain amyloid-beta (Aβ) deposition.
Reduced fluid intake correlated with increased markers of cerebrovascular injury.
These findings suggest a potential link between hydration and ADRD pathology.

Conclusions:

Hydration may be a modifiable factor influencing ADRD risk or progression.
Further research is needed to confirm causality and explore clinical implications.
Hydration status should be considered in future ADRD research and patient care.
