A recent study has revealed critical predictors for dementia that may significantly assist in early detection and intervention. The findings indicate that newly diagnosed patients exhibit notably different behaviors regarding financial assistance from family members. Specifically, 25% of respondents with a dementia diagnosis sought financial help from their children, in stark contrast to only 2% of those without such a diagnosis. This trend underscores the profound impact dementia has on both the individual and their families.
Millions of Americans currently face the risk of developing dementia, making it essential to identify and understand the contributing factors. The research highlights that early detection, alongside proactive lifestyle changes, can delay the onset of dementia and alleviate its effects. Cognitive ability, lifestyle choices, and overall physical health can indicate dementia risk up to two decades prior to the appearance of symptoms.
Several common risk factors were identified in the study. A history of limited work experience or a lack of private health insurance by age 60 significantly increases the likelihood of developing dementia. Additionally, having diabetes, experiencing a stroke, and maintaining poor physical health are all notable risk factors. The study also emphasizes the importance of physical activity; individuals who do not exercise regularly are at heightened risk.
Clifford Segil, a clinician involved in the study, remarked on the findings:
“This report noted in common sense language risk factors which I see increase people getting dementia which included a stroke, poor health, diabetes. I was surprised to see data support a history of only working for a few years or not having private health insurance at age 60 being increased risk factors for developing dementia. Refreshing to read an article on dementia not supporting early diagnosis with a blood test which clinicians like me strongly disagree should be done.”
Segil further emphasized that lifestyle modifications could play a significant role in preventing dementia:
“This paper advised performing physical exercise, working additional years, engaging in hobbies and novel information activities after retirement, and maintaining good physical health are likely to prevent someone from developing dementia. I think these lifestyle modifications should be shared with anyone trying to avoid getting memory loss or dementia as they age.”
The study also pointed out that genetic factors contribute significantly to the risk of cognitive impairment and dementia. Certain genes can be strong indicators of future cognitive decline. Moreover, individuals with a body mass index (BMI) of 35 or more at age 60 and those who either abstain from alcohol or consume it excessively are also at increased risk.
Segil cautioned that while factors like physical activity and social engagement correlate with lower dementia risk, the study does not definitively conclude whether these behaviors prevent cognitive decline or merely reflect better baseline cognitive health.
