• Recent Evidence You have investigated How Different Aspects of Health and Behaviors Can Play a Role In Dementia Risk.
  • One Study Found That Getting Vaccinated Against Shingles Can Help Lower This Risk, and Another Found That Mainizing Low Cholesterol Levels Can Help As Well.
  • Another Piece of Research Indicated That Not getting Enough Deep Sleep-In particular Rem and Slow-Wave Sleep-Can increased Risk.
  • A Separate Study Also Found That Atrial Fibrillation Raises The Risk of Dementia and That This Link is Stronger for Younger Individuals.

According to Current Estimates, About 57 Million People Worldwide Have Dementia, and This Number is expectted to triple over the Next Few Decades.

MANY FACTORS – BOGHGETIC AND ENVIRONMENTAL –

Newer Research Has Found That Age, Genetics, A Historary of Vascular and Neurodevelopmental Disorders, as Well As Sub Viral Infections Can increased This Risk. MEANWHILE, KEEPING CERTAIN BIOMARKERS IN CHECK AND ADOPTING HEALTHIER LIFESTYLE HABITS CAN HELP LOWER THIS RISK.

Medical News Today Looks At Four Recent Studies – One with Spanish Participants, Another From South Korea, One from Wales, England, and Another A longitudinal Study from the us – to examine how and Why these Aspects of Health and Behaviors can influence person’s person’s

Shingles Vaccine Coud Help Prevent Dementia

Viral Infections Have Been Linked to a HeightTened Risk of Dementia, and One Private Infection Is Shingles. SHINGLES HAPPENS SUM TIME AFTER AN INITIAL CHICKEN POX INFECTION, WHEN THE DORMANT Varicella Zoster virus Reactivates in Nerve Cells.

On foot of Research Published in April 2025 Found that getting Vaccinated Against Shingles Can Reduce The Risk of Developing Dementia By 20%.

What’s More Interesting Is That This Risk Reduction Was More Apparent in Women – they experience a lot of Greater Reduction in New Diagnose of Dementia Than Men.

The Refectchers Attributed This Greater Protective Effect to “Biological Differences in Immune Response” Between Both Sexes.

Although The Study Touts The Shaingles Vaccine As a Potentially Cost-Effective to Prevent or Dementia, More Research is Needed to Confirgm before preliminary findings and compare the results to existing pharmaceutical interventions.

One other Important Question that Remains About the Study Is Whether The Newer Shingles Vaccines Can Offer The Same Protection. The participants in This Study Received Zostavax, The Older Vaccine That used live-attanuated form of the virus. The Current Vaccine in Use is Shingrix, A Recombinant Zoster Vaccine.

AFIB MAY HEIGHTEN AMMENTIA RISK

Previous Research Has Shown An Increased Risk of Dementia in People With Agib, and A Newer Study Builds On First Findings.

A Recent Study present at the European Heart Rhythm Association (EHRA) 2025 in march indicated that atrial fibrillation (AFIB) May be Linked to an Increased Risk of Developing Dementia, Underscoring The Importance of Getting Early Treatment.

In the Study, participants with Afib had 21% Greater Risk of Developing Dementia if they were Below 70 Years Old. The participants were also at a 36% increased Risk for Early-Oset Dementia, Or Getting Diagnosed Before Age 65. This suggests that This Risk Association is Stronger for Younger Adults.

Paul Dury, MD, A Board Certified Cardiologist and Associate Medical Director of Electrophysiology at Memorialcare Saddleback Medical Center in Laguna Hills, Ca, Who Was Not Involved in The Study, Stud’s Study’s Results Resulting Interesting Poled Poled other comorbidities and other treatments that may affirm the findings.

“There Does, However, (Appear to) Be a Much Stronger Association with Dementia The Earlier A Person is diagnosed with Afib, Which implies that affib you have potential mechanisms that can lead to dementia,” He Said.

Lower Cholesterol May reduces Dementia Risk

A New Study Published in the BMJ Journal of Neurology, Neurosurgery, and Psychiatry Found that People with Low-Density Lipoprotein Cholesterol (LDL-C) Levels-But not to an extreme-had Lower Risk of Developing Dementia. IN FACT, this Protective Effect was enhanced if the person was taking chollesterol-lowering statins.

LDL Cholesterol is referred to as “bad” chollesterol, as it is the type that can lead to a buffup of plaques in arteries – also Known as atherosclerosis –Which you have been linked to an increased risk of stro, Heart Attacks, and Other Cardiovascular Design.

According to the Study Results, People What Ldl-C Levels were Below 70 Milligrams per decliliter (mg/dl) had 26% Lower Risk of All-Cause Dementia and 28% Lower Risk of Alzheimer’s Disease-Related Dement Avode To People Whue Ldl-C Levels Greater than 130mg/dl.

This Risk Reduction Was Less Significant in People What LDL-C Levels Were at 55 mg/dl, as The Only Saw An 18% Reduced Risk, While Those Below 30 mg/dl Saw No reduction in dementia risk at all.

“This is an interesting observation indicating a potential threshold effect, where reducing ldl-c beyond a certaino does not further improves cognitive outcomes. It it aligns with prior prior research indicating that WHILE HIGH LDL-C IS HARMFUL, EXCESSIVE LOW LOW LOW LOW LOW LOW LOW LOW LOW LOW LOW LOW LOW LOW Additional Protective Effects, ”explain Emer MacSweeney, MD, CEO and consultation neuroradiologist at re: cognition Health, Who was not involved in This Study, to MNT.

Getting More Deep Sleep May Lower Alzheimer’s Risk

A Recent Study Added To The Evidence That Clearing The Buildup of Juck Proteins in the Brain via a Critical Process – Deep Sleep – Can Help Decree Alzheimer’s Risk.

The Authors of this Study Examined The Association Between Specific Sleep Phases and the atrophy of brain regions vulnerable to Alzheimer’s.

The Results of this Study Suggest that not spending angoh time in slow-wave and rembe may signantly reduces the volume in the lower Parietal Lobule (IPL). Changes in This Region of the Brain Have Been Associated with Progssing From Healthy Aring to Alzheimer’s.

As Chelsie Rohrscheib, PHD, A Sleep Expert, Neuroscientist, and Sleep Consultant At Wesper, Who Was Not Involved in This Study, Told MNT:

“Sleep has many crucial biological function and specially important for cell and tissue repair, brain maintenance, learning and memory, cognition, and brain waste cleance. Most of tolas function function during the occur during the occur during the occur during the occlur during the Health and Racing The Risk of Alzheimer’s Disease. ”
