Is excessive syleepiness as we age a warning sign of dementia?

One Large-Scale Study Found That High or Low Sleep Duration Increased Risk of Cognitive Impairment and Dementia. Another Found that Short Sleep Duration in Middle Age Was Associated with Higher Dementia Risk.

To Third Suggests That Sleeping More than 9 Hours a Night is Associated With Neurodegeneration and Dementia.

All these studies relied on participant-repaired Sleep Duration, rather than objective measurement of shake and wakefulness.

Now, A Study Led By Scientists at the University of California, San Francisco, which used shales DEVELOPING DEMINIA.

The Study Appears in the Journal Neurology.

Ben Dunkley, PhD, A Cognitive Neuroscientist, Associate Professor in Medical Imaging at The University of Toronto, Canada, and Chief Science Officer At Myndspan, Who Was Not Involved in This Research, Told Medical News Today That “The Study Rightly Highlights The Bidirectional Relationship Between Sleepiness and Dementia; However, As The Authors Point Out, The Exact Direction of the Relationship Cannot Be Concluded With a correlation Study Such as This.”

Dunkley Explained That:

“Sleep Disturbances Could Indeed Signal Early neurodegenerative changes, acting as precursors to clinical symptoms. Conversley, dementia-related neurological changes might disruption the brain’s sleep-regulating centers, exacerbating Sleepiness. Crucially. CHANGES COULD BE USED TO PREDICT LIFE LIFE DEMENTIA RISK. “

The Study Recruited 733 Community-Dwelling Women from The Study of Osteoporotic Fractures (SOF)All of Whom Were AGED AT LEAST 65, COULD WALK WITOUT ASSISTANCE AND HAD NIGH TWO HIP REPLACEMENTS. The Mean Age of the participants was 82.5 Years.

No participants had cognitive unpaid or dementia at Baseline.

Researchers Gave All Participants An Actigraph, which they wore on their Wrists to Measure Their 24-Hour Sleep-Wake Activity.

For Their Data To Be included in the analysis, participants had to attend the clinic in person, and have at least 3 consecutive days off actigraph measurements at both initial visit and find-year follow-up, as well as complete to Sleep log.

From the data, Remember 5-Year Changes in Night-Time Sleep, Napping and Circadian Rest-Activity Rhythms (Rars-Magnitude, Timing and Regularity of Rest-Activity Patterns).

They identified Three Main Sleep Profiles:

1. Stable Sleep (SS), SEEN IN 321 Women (43.8% of the Cohort), was Characterized by Stable Or Slightly Improved Sleep
2. Declining Nighttime Sleep (DNS) – A Total of 256 Women (34.9%) had decreases in nighttime Sleep Quality and Duration, moderate increases in napping, and worsening circadian rars
3. INCREASING SLEEPINESS (IS) – BEGES 156 Women (21.3%) HAD LARGE INCREASES IN BOYTIME AND NIGHTIME SLEEP DURATION AND QUALITY, AS WELL AS WORLSENING CIRCADIAN RARS.

At the end of the 5-year journal, stress determinated whereher participants had normal cognition, Mild Cognitive Unpaid (MCI), Or Dementia, Based on a Number of Neuropsychological Tests, Physician Diagnosis, Or Admission to Residential Nursing Home Care. Anyone Negative for All Tohe Criteria was Judged to Be Cognitive Normal.

The Rebecchers Adjusted for Age, Education, Race, Body Mass Index, Diabetes, Hypertension, Heart Attack, Use of Antidepressants, and Cognitive Ability at Baseline When Analysing Their Results.

Of The Elderly Cohort, 164 (22.4%) Women Developed MCI and 93 (12.7%) Developed Dementia During the 5-Year Follow-Up.

Women with Amazing 24-Hour Sleepiness Had Approximately Double The Dementia Risk of Those With Stable Sleep Profiles Over The 5 Years. However, Increased Sleepiness was not associated with increased Risk of Mci.

The Refrachers Emphasize that their observational Study Cannot Show The Direction of the Relationship Between Excessive Sleep and Dementia.

Steve Allder, MDM Consultant Neurologist at Re: Cognition Health, Who Was Not Involved in This Study, Told MNT That:

“Older Adults in the preclinical Stages of Dementia May Experience Increased Daytime Sleep As a Response to Brain Changes AFFFECING ARUSAL AND ALErtness. Neurodegeneration in Regions Like the Hypothalamus and Brainstem, which regulates Sleep, could result in Greater Daytime Sleep Needs. Inflammation and vascular risk may (Also) be contribution factor.

“Increased Sleepiness and Frequent Napping May Be Linked To Dementia Due To Several Underlying Factors,” Allder Told MNTAdding That “One Key Reason is Sleep Fragmentation and Neurodegeneration-Poor Nighttime Sleep Quality Can Disrupt Deep Sleep, which is Essential for Clearing Amyloid-Beta, A Protein Associated With Alzheimer’s Disease.”

“Circadian Disruption Also Plays A Role, As Worsening Sleep-Wake Cycles and Irregular Circadian Rhythms Are Associated With Neurodegenerative Changes.

Concurring with the Refectchers’ Suggestion that Increased Sleepiness Might Be A Result of Early Dementia, Allder Also Explained That Excessive Sleepiness Might Acts A Compensatory Mechanism for Brain Dysfunction.

This Study Provides Further Evidence that Altered Sleep Patterns in Older Age May contributes to the Risk of Dementia.

Dunkley offered advice for mainting Good Sleep Patterns.

“Beyond Sleepiness Alone, Disruptions Like Fragmented Sleep, Reduced Sleep Efficient, and Irregular Circadian Rhythms Are Strongly Linked to Dementia Risk,” “He Told Us.

His and His Colleagues’ Experience with People in Real-World Scenarios, He Further Advised, ”Supports Findings That Improving Sleep Quality Through Lifestyle Modifications-Such As Consistenc Enhance Brain Health. “

“Technologies Like Magnetoenchalography (MEG), Combined with Lifestyle Tracking Tools Such As Wearable Sleep Monitor, Enable Individuals to Objectively Monitor Improvements In Their Sleep and Cognitive Health,” Dunkley Also Nothed.
