Higher Triglycerides Tied to Lower Dementia Risk

Older individuals with elevated triglyceride levels might be at a reduced risk for dementia. Researchers studied over 18,000 seniors without prior dementia diagnoses, monitoring them for six years.

Mild cognitive impairment was diagnosed by a panel of researchers who reviewed each participant´s performance across several tests.

Subtle Test Deficits: A Quiet Prelude to Cognitive Decline?

A recent study reveals a potential predictive indicator for mild cognitive impairment (MCI), often a forerunner to dementia, in individuals reporting subjective cognitive decline yet displaying only subtle test deficits. The investigation, encompassing 439 participants averaging 71 years of age, identified that those with minor test deficits were over four times more likely to progress to MCI compared to their counterparts without such deficits.

Early Concussions Tied to Faster Cognitive Decline

A recent study reveals a link between early-life concussions and faster cognitive decline in later years. Conducted on World War II veteran twins, the research showed that twins with a history of traumatic brain injury (TBI) scored lower on cognitive tests and exhibited quicker decline than their non-injured counterparts.

Long-term Acid Reflux Drugs Linked to Higher Dementia Risk?

Long-term use (over 4.4 years) of proton pump inhibitors, prescribed for acid reflux, may be associated with an increased risk of dementia. However, this research does not establish a direct causation but reveals an association.

Early Odor Detection Loss Linked to Alzheimer’s Gene Variant

Individuals carrying a gene variant associated with Alzheimer's disease, APOE e4, may experience early loss in their ability to detect odors, hinting at future cognitive challenges. The study employed an at-home survey to test over 865 people's sense of smell and cognitive skills at five-year intervals.

Loneliness in Elderly Tied to Brain Volume Reduction

A new study finds a link between social isolation in older adults and decreased brain volume, particularly in areas affected by dementia. Conducted on nearly 9,000 participants without dementia, the research found that those with the least social contact had significantly lower overall brain volume compared to those with more social interactions.

Sleep Apnea and Its Link to Alzheimer’s Associated Brain Changes

A new study uncovers a new link between sleep apnea and brain volume in Alzheimer's susceptible regions. The study found that people with Alzheimer's disease-linked amyloid plaques and severe sleep apnea were more likely to have reduced volumes in memory-associated regions of the brain, like the hippocampus.

Regular Exercise Linked to Lower Parkinson’s Risk

Regular physical activity, from cycling and walking to gardening and household chores, may reduce the risk of developing Parkinson’s disease. The study found that women who exercised the most had a 25% lower rate of Parkinson’s disease compared to those who exercised the least. This study does not establish that exercise directly lowers the risk of developing Parkinson's disease, but it does show a significant association.

This shows a person sleeping and brain activity.

Link Between Sleep Apnea, Deep Sleep Deficit, and Brain Health Risks

A new study reveals a potential link between sleep apnea, reduced time in deep sleep, and brain biomarkers associated with increased risk of conditions like stroke, Alzheimer’s disease, and cognitive decline.

Long COVID’s Lingering Impact: Brain Function Changes Can Persist for Months

People with long COVID have abnormal brain activity during memory tests, months after their initial COVID-19 infection, with less activity in the regions normally used for memory tasks, but more activity in other areas of the brain. Although people who had COVID-19 had cognitive test scores similar to those who never had a history of coronavirus, those who had long COVID had greater brain activation on a working memory task compared to people without prior COVID-19 infections.

Multiple Sclerosis Drug May Delay Earliest Symptoms

Early intervention with the multiple sclerosis treatment Teriflunomide delays the preliminary symptoms of the autoimmune disease, a new study reports. Those who took teriflunomide had a 72% lower risk of experiencing the initial symptoms of MS than those who took a placebo.
