Abnormal liver enzyme levels detected by commonly used blood tests may be linked to Alzheimer’s disease diagnosis and multiple biomarkers of the disease, according to a recent study. The findings were published July 31 in JAMA Network Open. Led by NIA-supported scientific teams at Duke University and Indiana University, the research was based on the rationale that abnormal changes in liver enzymes are associated with heart disease and metabolic disorders like diabetes, which are known risk factors for Alzheimer’s.
High blood pressure is linked to a lot of common health problems, most notably stroke and heart disease. Scientists have also established a link between high blood pressure and increased dementia risk. But a new study finds that an uptick in blood pressure — even as early as your 30s — could lead to a higher dementia risk later on.
In a nationwide study, researchers used magnetic resonance imaging (MRI) to scan the brains of hundreds of participants in the National Institutes of Health’s Systolic Blood Pressure Intervention Trial (SPRINT) and found that intensively controlling a person’s blood pressure was more effective at slowing the accumulation of white matter lesions than standard treatment of high blood pressure. The results complement a previous study published by the same research group which showed that intensive treatment significantly lowered the chances that participants developed mild cognitive impairment.
More and more studies are showing how regular exercise benefits the brain, and in particular, the aging brain. What’s less clear is how exactly exercise counters the cognitive decline that comes with aging and diseases like Alzheimer’s.
Following a healthy lifestyle is associated with a lower risk of dementia in cognitively healthy older adults at varying levels of genetic risk for Alzheimer’s disease and related dementias, according to a study published online July 14 in JAMA. Funded in part by NIA, the study is the first to examine the relationship between multiple genetic risk factors for dementia and multiple lifestyle factors.
