Make damn sure your competent? doctor has EXACT PROTOCOLS that prevent frailty post stroke! Doesn't have them; fire him/her and replace your incompetent board of directors!

One overlooked sign of aging may reveal dementia risk years earlier
A common but often overlooked condition could help identify people at risk of developing dementia years before symptoms appear, according to new research.
Researchers have found that frailty—a medical condition characterized by reduced physical resilience and increased vulnerability to illness—was linked to an earlier onset of dementia, even among people with relatively low levels of Alzheimer’s-related brain pathology.
The study, published in the Journal of Neurology, Neurosurgery & Psychiatry, analyzed data from 1,614 community-dwelling older adults who participated in the Rush Memory and Aging Project in Illinois.
Participants were followed for nearly 24 years on average, allowing researchers to examine how frailty influenced the age at which dementia was diagnosed.
Frailty was assessed using a frailty index, which takes into account a wide range of health and functional measures. Researchers classified participants with scores of 0.25 or higher as frail.
The results showed that frailty was associated with developing dementia at a younger age. Overall, frail individuals received a dementia diagnosis approximately two to three years earlier than those who were not frail.
“The best approach to preventing or reducing frailty is a combination of regular physical activity, particularly strength training, and a diet that ensures adequate protein intake,” study co-author Dr. David Ward, a research fellow in aging and geriatric medicine at the Centre for Health Services Research, Faculty of Medicine at the University of Queensland, told Newsweek.
Ward also advised regularly reviewing medications with a doctor and discussing whether chronic conditions could be managed more effectively.
While the study did not prove that reversing frailty prevents dementia, Ward said the findings suggest that maintaining physical health and resilience “could potentially help delay when dementia becomes clinically apparent.”
The association was observed across men and women, regardless of education level or whether participants carried the APOE ε4 gene, one of the strongest known genetic risk factors for Alzheimer’s disease.
To better understand the relationship, the researchers also examined a subgroup of 906 participants who underwent brain autopsies after death.
They compared frailty levels with the amount of neuropathology present in the brain, including markers associated with Alzheimer’s disease and other forms of dementia.
Among people who had relatively low levels of dementia-related brain pathology, frailty was linked to an almost 10 percent earlier age of dementia diagnosis.
Interestingly, the same association was not seen among those with intermediate or high levels of brain pathology.
The findings suggest that frailty may contribute to dementia through pathways that operate independently of the underlying brain changes typically associated with neurodegenerative disease.
In other words, a person’s overall physical health and resilience may influence when dementia symptoms become noticeable, even when brain pathology alone would not fully explain the diagnosis.
Ward said frailty often develops gradually, meaning the earliest signs can be easy to miss.
“These can include walking more slowly, declining strength, reduced activity, persistent tiredness or taking longer to recover from illness,” he said.
Ward also advised anyone experiencing ongoing changes in their physical or day-to-day functioning—particularly if they are affecting routine activities—to speak with a doctor.
“A doctor can assess frailty and identify potentially treatable contributors,” he said.
