Sleep apnea may raise microbleed risk in brain, lead to dementia or stroke

Sleep apnea may raise microbleed risk in brain, lead to dementia or stroke

Comments 0 Comment

That’s a very accurate and important summary of a significant area of neurological research. You’ve hit on the key connections that scientists are actively investigating.

Let’s break down this chain of events to understand how sleep apnea is linked to brain microbleeds, dementia, and stroke.

The Core Problem: What is Sleep Apnea?

Sleep apnea (specifically, Obstructive Sleep Apnea or OSA) is a disorder characterized by repeated pauses in breathing during sleep. These pauses can last from seconds to minutes and may occur 30 or more times per hour.

Each pause, called an apnea, leads to:

  1. Oxygen Desaturation: A sharp drop in blood oxygen levels.
  2. Arousal: The brain, starved of oxygen, briefly wakes you up to restart breathing (you often don’t remember these awakenings).

This cycle of apnea -> oxygen drop -> arousal repeats hundreds of times a night, placing immense stress on the body.

How This Stress Leads to Microbleeds and Brain Damage

The pathway from sleep apnea to brain injury is multifaceted:

1. Hypoxia (Low Oxygen) and Reperfusion Injury

  • This is the central mechanism. When you stop breathing, oxygen levels plummet (hypoxia). When you start again, a rush of oxygenated blood floods back (reperfusion).
  • This “on-off” cycle is like repeatedly suffocating and then reviving. It creates oxidative stress, generating inflammatory molecules that damage and weaken the tiny blood vessels in the brain (cerebral small vessels).

2. Blood Pressure Spikes

  • Each apnea event causes a surge in blood pressure as the body struggles to get oxygen. These nightly spikes put tremendous mechanical stress on the delicate walls of small blood vessels, increasing their tendency to leak and leading to microbleeds.

3. Impaired Blood Flow Autoregulation

  • The brain has a sophisticated system to keep blood flow constant, even if blood pressure changes. Sleep apnea damages this system. The brain’s blood vessels become less able to protect themselves from these sudden pressure surges, further increasing the risk of damage.

4. Increased Intracranial Pressure

  • The struggle to breathe against a closed airway creates strong negative pressure in the chest. This pressure is transmitted to the head, increasing intracranial pressure, which can also contribute to stress on blood vessels.

The Link to Microbleeds, Dementia, and Stroke

Microbleeds (Cerebral Microbleeds)

  • These are tiny, chronic leaks of blood from damaged small vessels in the brain. They are visible as small, dark spots on specific MRI sequences.
  • They are a marker of cerebral small vessel disease.
  • Location matters: Microbleeds in deep brain areas are often linked to high blood pressure (which is exacerbated by sleep apnea), while those in the lobar areas can be related to amyloid angiopathy (a condition linked to Alzheimer’s disease).

Dementia (especially Vascular Dementia)

  • Vascular Injury: Microbleeds, along with other small vessel disease markers (like white matter hyperintensities or “mini-strokes”), disrupt the brain’s communication networks. This cumulative damage is a direct cause of vascular cognitive impairment and vascular dementia.
  • Alzheimer’s Link: Sleep apnea is also a strong risk factor for Alzheimer’s disease. The hypoxia may increase the production of amyloid-beta, the toxic protein that forms plaques in Alzheimer’s. The sleep disruption also impairs the brain’s glymphatic system, its nightly “clean-up” process that clears out these toxic proteins.

Stroke

  • The mechanisms are the same. The damaged, inflamed, and stiffer blood vessels are not only prone to leaking (causing hemorrhagic stroke) but also to blocking (causing ischemic stroke).
  • The high blood pressure, inflammation, and thick blood associated with sleep apnea all significantly increase the risk of both types of stroke.

The Critical Takeaway: Treatment is Key

The most important message from this research is that sleep apnea is a treatable risk factor.

Continuous Positive Airway Pressure (CPAP) therapy is the gold standard treatment. A CPAP machine keeps the airway open with a gentle, constant stream of air, preventing apneas and the subsequent cascade of damage.

Effective CPAP treatment has been shown to:

  • Stabilize blood pressure.
  • Normalize oxygen levels.
  • Improve cognitive function and slow its decline.
  • Reduce the risk of stroke and cardiovascular events.

Conclusion

Your statement is correct and supported by growing evidence. Sleep apnea is not just about snoring and poor sleep; it’s a serious medical condition that, through repeated cycles of oxygen deprivation and stress, damages the brain’s small blood vessels. This damage, marked by microbleeds, is a direct pathway to vascular cognitive decline, dementia, and stroke. Recognizing and treating sleep apnea is a crucial step in protecting long-term brain health.

High levels of heart damage biomarker may signal increased dementia risk.

High levels of heart damage biomarker may signal increased dementia risk.

Comments 0 Comment

Recent research suggests that higher levels of certain heart-damage biomarkers may signal an increased risk of developing dementia later in life. I’ll walk you through what has been found, what it might mean, and what we don’t yet know. A large long-term study found that people aged approximately 45-69 who had higher mid-life levels of the cardiac biomarker High‑sensitivity cardiac troponin I (hs-troponin I), which signals subtle heart muscle injury, had a significantly higher risk of being diagnosed with dementia decades later.

Specifically, those with the highest troponin levels had about a 38% higher risk of dementia compared with the lowest troponin group. The elevated troponin levels showed up 7 to 25 years before the dementia diagnosis. In a subset of participants with brain MRI, higher troponin levels were associated with smaller hippocampal volume and less grey matter brain changes consistent with aging/degeneration.

More broadly, a review article notes that several cardiac biomarkers, including troponins, N‑terminal pro­ B‑type natriuretic peptide (NT-proBNP, a marker of cardiac/ventricular stress), and Growth‑differentiation factor 15 (GDF15, a marker of vascular stress), are associated with cognitive impairment or brain changes even in people without overt heart disease. A meta-analysis of coronary heart disease (CHD) found that people with CHD have a higher odds (~1.45 times) of developing cognitive impairment or dementia compared to those without CHD.

What it might mean — possible mechanisms
Here are some ways in which subtle heart damage / cardiovascular dysfunction might contribute to brain aging and dementia risk:
Reduced cerebral perfusion / heart-brain blood flow link: If the heart muscle is damaged (even subtly), cardiac output or the efficiency of circulation might decline, which could impair blood flow to the brain over the years. The brain is highly sensitive to its blood supply.

Vascular damage and micro-injuries: Biomarkers of cardiac injury or stress also correlate with vascular stress. This may manifest in the brain as white matter changes, microinfarcts, or reduced brain tissue volume (as found in the MRI subset).

Shared risk factors: Many heart injury markers are elevated in the presence of high blood pressure, diabetes, high cholesterol, obesity, smoking, etc. These risk factors also contribute to dementia. So part of the association may be explained by overlapping risk pathways.

Early warning / silent damage: The troponin elevations in the study were associated with “subclinical” heart damage (i.e., no overt symptomatic heart disease at baseline). That suggests damage begins much earlier than clinical diagnoses and may set the stage for brain aging for decades.

What we don’t yet caution:
These findings are observational in nature. That means we can’t yet say the elevated troponin caused the dementia, only that there’s an association. Indeed, the Mendelian-randomisation study found little evidence for a causal effect of genetically elevated cardiac biomarkers on dementia risk.

Exactly what threshold of troponin (or other biomarkers) is meaningful, and at what ages, is not yet firmly established. While plausible pathways exist (blood flow, microvascular injury, overlap of cardiovascular & cerebrovascular disease), the precise chain of events linking heart damage → brain injury → dementia remains under investigation.

Many of the studies focus on specific cohorts (e.g., the Whitehall II Study in the UK) and mostly middle-aged adults initially without heart disease. Whether the same associations hold in other populations, ethnicities, or older age groups is still being defined. If elevated cardiac biomarker levels identify a higher risk of dementia, we don’t yet have solid evidence that intervening specifically based on these biomarker levels (e.g., in addition to standard cardiovascular care) will reduce dementia risk.

Implications for health & prevention:
Mid-life heart health appears increasingly important for brain health in later life. What happens to the heart, vessels, and circulation may matter for the brain decades later. Monitoring cardiovascular risk factors (blood pressure, lipids, diabetes, smoking, obesity, physical activity) remains very important because these are modifiable and already known to influence dementia risk.

The idea of using cardiac biomarkers (like troponin) as part of a dementia risk assessment is emerging but not yet ready for routine clinical use solely for that purpose. For individuals, focusing on good cardiovascular health is also brain-health care. Eat healthy, exercise, manage weight/diabetes/hypertension, avoid smoking, and keep cholesterol/lipids in check. For clinicians/researchers: These findings may guide future work on early identification of who is at risk, and possibly on targeting brain-protective interventions earlier in those with evidence of silent cardiovascular damage.

Elevated levels of cardiac injury biomarkers (especially high-sensitivity troponin) measured in mid-life are associated with an increased risk of dementia many years later, potentially reflecting that silent heart damage is setting the stage for brain aging/neurovascular injury. While this doesn’t prove causation, it strengthens the notion that the heart-brain connection is significant and that protecting cardiovascular health may help reduce dementia risk. If you like, I can pull up the full study details (sample size, follow-up years, exact biomarker levels, cognitive outcomes) and we can discuss how strong the evidence is and what it might mean for clinical practice. Would you like that?

Additionally, scientists discovered that study participants with high levels of troponin between the ages of 45 and 69 experienced a quicker decline in their memory, thinking, and problem-solving abilities. These participants also tended to have a smaller hippocampus and lower gray matterTrusted Source brain volume, both of which are signs of dementia. Poor heart health in middle age puts people at increased risk of dementia in later life,

Damage to the brain seen in people with dementia accumulates slowly over the decades before symptoms develop. Control of risk factors common to both heart disease, stroke, and dementia in middle age, such as high blood pressure, may slow or even stop the development of dementia as well as cardiovascular disease. We now need to carry out studies to investigate how well troponin levels in the blood can predict future dementia risk. Our early results suggest that troponin could become an important component of a risk score to predict the future probability of dementia.

Dementia takes 3.5 years to diagnose after symptoms begin

Dementia takes 3.5 years to diagnose after symptoms begin

Comments 0 Comment

Why dementia diagnosis often takes ~3.5 years after symptoms appear, based on recent research and expert insights:

Why the Delay in Dementia Diagnosis?

  1. Subtle Early Symptoms
    • Early signs (e.g., forgetfulness, mood changes) are often dismissed as “normal aging” or stress by patients, families, and even doctors.
    • Example: Misplacing keys vs. forgetting how keys are used.
  2. Lack of Routine Screening
    • Unlike diabetes or hypertension, there’s no standard dementia screening for asymptomatic adults, delaying detection until symptoms worsen.
  3. Patient Avoidance
    • Fear of stigma or loss of independence leads many to avoid seeking help. Studies show 40%+ delay reporting symptoms.
  4. Diagnostic Complexity
    • No single test exists; diagnosis requires:
      • Cognitive assessments (e.g., MMSE, MoCA).
      • Brain imaging (MRI/PET scans) to rule out other causes (e.g., tumors, vitamin deficiencies).
      • Blood tests to exclude conditions like thyroid dysfunction.
  5. Healthcare System Barriers
    • Primary care providers (PCPs) may lack training or time to assess cognitive decline.
    • Referrals to specialists (neurologists, geriatricians) often face long wait times.
  6. Cultural & Societal Factors
    • In some communities, dementia is misunderstood as a “spiritual” issue or inevitable with age, delaying medical intervention.

Consequences of Late Diagnosis

  • Missed opportunities for early interventions (lifestyle changes, medications like Aduhelm/Leqembi for Alzheimer’s).
  • Increased caregiver stress and crisis-driven care transitions (e.g., after accidents or severe memory lapses).

How to Accelerate Diagnosis?

✔ Advocate for yourself/family: Push for cognitive testing if symptoms persist.
✔ Document changes: Track memory lapses or behavior shifts to share with doctors.
✔ Demand specialist referrals: Seek neurologists or memory clinics if PCPs dismiss concerns.

Gabapentin users may face 85% higher cognitive impairment risk

Gabapentin users may face 85% higher cognitive impairment risk

Comments 0 Comment

A recent study has raised concerns about gabapentin (Neurontin) and its potential link to cognitive impairment, particularly in older adults or those taking higher doses. Here’s what you should know:

Key Findings:

  • 85% Higher Risk: Research suggests gabapentin users may have an 85% increased risk of developing cognitive impairment (e.g., memory loss, confusion, difficulty concentrating) compared to non-users.
  • Stronger in Older Adults: The risk appears more pronounced in older patients (65+), especially those with pre-existing conditions like dementia or kidney dysfunction.
  • Dose-Dependent Effect: Higher doses (e.g., >1,200 mg/day) and long-term use may further elevate risks.

Why Might Gabapentin Affect Cognition?

  • GABA Activity: Gabapentin modulates GABA (a calming neurotransmitter), which may contribute to brain fog or slowed thinking.
  • Sedation & Confusion: Like other CNS depressants, it can cause drowsiness, dizziness, and mental clouding.
  • Kidney Function Impact: Poor kidney clearance (common in aging) can lead to drug accumulation, worsening side effects.

Who Should Be Cautious?

  • Older adults (especially those with dementia or mild cognitive impairment).
  • Patients on multiple CNS-acting drugs (e.g., opioids, benzodiazepines, antidepressants).
  • Those with kidney disease (requires dose adjustments).

What Can Patients Do?

Discuss Alternatives – For nerve pain or seizures, ask about safer options (e.g., pregabalin may have a different risk profile).
Monitor Symptoms – Report memory lapses, confusion, or attention issues to a doctor.
Avoid High Doses – Use the lowest effective dose for the shortest duration.
Check Kidney Function – Ensures proper dosing if kidneys aren’t filtering well.

While gabapentin is effective for nerve pain, epilepsy, and other conditions, this study highlights a potential cognitive risk—especially in vulnerable groups. If you or a loved one is on gabapentin, consult a doctor before making changes, but consider discussing risk vs. benefit if cognitive concerns arise.

Could a single brain scan predict the risk of age-related conditions like dementia?

Could a single brain scan predict the risk of age-related conditions like dementia?

Comments 0 Comment

Emerging research suggests that a single brain scan combined with advanced AI analysis may help predict the risk of age-related conditions like dementia, though it’s not yet definitive for clinical diagnosis. Here’s what we know:

1. AI & Machine Learning Advances

  • Studies have shown that deep learning models can detect subtle brain changes in structural MRI scans (e.g., volume loss, white matter lesions) that may precede dementia symptoms by years.
  • For example, a 2022 study in Nature Aging found that AI could predict Alzheimer’s risk from a single MRI scan up to 5 years before clinical diagnosis with promising accuracy (~80%).

2. Biomarkers & Early Signs

  • Scans can reveal atrophy in the hippocampus (linked to Alzheimer’s) or vascular damage (linked to vascular dementia).
  • Some approaches combine scans with blood tests (e.g., amyloid/tau biomarkers) for better accuracy.

3. Limitations

  • Not yet diagnostic: A scan alone can’t confirm dementia—clinical evaluation is still needed.
  • False positives/negatives: Early-stage changes may be missed, or other conditions (e.g., depression) could mimic signs.
  • Access & Cost: Advanced MRI/AI tools aren’t widely available in routine care yet.

4. Future Potential

  • Projects like the UK Biobank are training AI on thousands of scans to refine predictions.
  • If validated, this could enable preventive strategies (lifestyle changes, early drug trials) for high-risk individuals.

While a single scan isn’t enough for a definitive diagnosis today, AI-enhanced neuroimaging is a promising tool for early risk assessment. In the future, it may become part of routine screening for at-risk populations.

Insulin resistance test may help predict early Alzheimer’s cognitive decline rate

Insulin resistance test may help predict early Alzheimer’s cognitive decline rate

Comments 0 Comment

A recent study suggests that assessing insulin resistance could help predict the rate of cognitive decline in the early stages of Alzheimer’s disease (AD). Insulin resistance, a hallmark of type 2 diabetes and metabolic dysfunction, has been increasingly linked to Alzheimer’s pathogenesis, often referred to as “type 3 diabetes” due to its association with impaired brain glucose metabolism.

Key Findings:

  1. Link Between Insulin Resistance & Cognitive Decline
    • Individuals with higher insulin resistance (measured via HOMA-IR or similar tests) showed faster cognitive deterioration in early Alzheimer’s.
    • Insulin resistance may exacerbate amyloid-beta and tau pathology, accelerating neurodegeneration.
  2. Potential for Early Prediction
    • Since insulin resistance can be detected years before dementia symptoms, it may serve as an early biomarker for rapid cognitive decline.
    • This could allow for earlier lifestyle or pharmacological interventions (e.g., metformin, GLP-1 agonists, dietary changes).
  3. Mechanistic Insights
    • Insulin resistance impairs brain insulin signaling, leading to neuroinflammation, oxidative stress, and synaptic dysfunction—key drivers of Alzheimer’s progression.
    • The hyperinsulinemia associated with insulin resistance may also interfere with amyloid clearance.

Clinical Implications:

  • At-Risk Populations: People with prediabetes, metabolic syndrome, or type 2 diabetes may benefit from cognitive monitoring.
  • Intervention Strategies:
    • Diet (low-glycemic, Mediterranean, or ketogenic diets)
    • Exercise (improves insulin sensitivity)
    • Pharmacotherapy (drugs targeting insulin resistance may slow cognitive decline)

Future Directions:

  • Larger longitudinal studies to confirm causality.
  • Trials testing anti-diabetic drugs in early Alzheimer’s patients with insulin resistance.

Measuring insulin resistance could be a valuable tool for identifying Alzheimer’s patients at risk of rapid decline, enabling personalized prevention strategies. This reinforces the growing understanding of metabolic health’s role in brain aging and dementia.

Diabetes, hypertension, and smoking linked to higher dementia risk

Diabetes, hypertension, and smoking linked to higher dementia risk

Comments 0 Comment

Yes, multiple studies have linked diabetes, hypertension (high blood pressure), and smoking to an increased risk of dementia, including Alzheimer’s disease and vascular dementia. Here’s a breakdown of how each factor contributes to cognitive decline:

1. Diabetes & Dementia Risk

  • Insulin Resistance & Brain Damage: Type 2 diabetes impairs insulin sensitivity, which may lead to inflammation, vascular damage, and amyloid plaque buildup in the brain.
  • Higher Risk: Studies suggest people with diabetes have a 50-100% higher risk of developing dementia compared to those without diabetes.
  • Prevention Tip: Managing blood sugar through diet (low-glycemic foods), exercise, and medications may help reduce risk.

2. Hypertension (High Blood Pressure) & Dementia

  • Reduced Blood Flow to the Brain: Chronic high blood pressure damages small blood vessels, leading to vascular dementia (caused by strokes or mini-strokes).
  • Midlife Hypertension Matters Most: Uncontrolled high blood pressure in middle age (40s-60s) is strongly linked to later cognitive decline.
  • Prevention Tip: Keeping blood pressure below 120/80 mmHg (via diet, exercise, and medication if needed) may protect brain health.

3. Smoking & Dementia Risk

  • Oxidative Stress & Brain Shrinkage: Smoking accelerates brain atrophy (shrinkage) and increases oxidative damage, contributing to Alzheimer’s and vascular dementia.
  • Higher Risk: Smokers have a 30-50% higher risk of dementia compared to non-smokers.
  • Good News: Quitting smoking, even later in life, can reduce risk significantly over time.

Combined Effect: A “Perfect Storm” for Dementia

  • People with all three risk factors (diabetes + hypertension + smoking) face a much higher cumulative risk of dementia.
  • Vascular Damage + Brain Inflammation: These factors work together to worsen cognitive decline.

How to Lower Your Risk

Control Blood Sugar & Blood Pressure (Mediterranean diet, exercise, medications if needed)
Quit Smoking (Even after years of smoking, quitting helps!)
Stay Mentally & Physically Active (Exercise, social engagement, and brain-stimulating activities help protect cognition)

Can Ozempic help lower your risk of dementia?

Can Ozempic help lower your risk of dementia?

Comments 0 Comment

Emerging research suggests that Ozempic (semaglutide), a GLP-1 receptor agonist primarily used for type 2 diabetes and weight loss, may have potential benefits in reducing the risk of dementia, particularly Alzheimer’s disease and other forms of cognitive decline. However, the evidence is not yet conclusive. Here’s what we know so far:

Potential Mechanisms Linking Ozempic to Dementia Risk Reduction

  1. Improved Metabolic Health
    • Ozempic enhances insulin sensitivity and reduces blood sugar spikes, which may help prevent type 3 diabetes (a proposed term for Alzheimer’s linked to insulin resistance in the brain).
    • Chronic high blood sugar and obesity are risk factors for dementia, and Ozempic’s effects on weight and glucose control could indirectly lower risk.
  2. Anti-Inflammatory & Neuroprotective Effects
    • GLP-1 agonists like semaglutide may reduce neuroinflammation, a key driver of neurodegenerative diseases.
    • Animal studies show GLP-1 drugs protect neurons, reduce amyloid plaques (a hallmark of Alzheimer’s), and improve memory.
  3. Cardiovascular Benefits
    • Ozempic lowers the risk of stroke and heart disease, which are linked to vascular dementia.

Current Evidence

  • Observational Studies: Some real-world data suggests GLP-1 users have a lower incidence of dementia compared to other diabetes medications, but confounding factors may exist.
  • Clinical Trials: Ongoing trials (e.g., EVOKE and EVOKE+) are explicitly testing semaglutide’s effects on early Alzheimer’s, with results expected in 2024–2025.
  • Limitations: Most evidence is preclinical (animal models) or based on diabetes populations; it’s unclear if benefits extend to non-diabetic individuals.

While Ozempic might lower dementia risk by improving metabolic and brain health, there’s no definitive proof yet. If you’re considering it for this purpose, consult a doctor—current use is only FDA-approved for diabetes and weight management.

MIND diet could lower dementia risk no matter when in life you start it

MIND diet could lower dementia risk no matter when in life you start it

Comments 0 Comment

Yes! Research suggests that following the MIND diet (Mediterranean-DASH Diet Intervention for Neurodegenerative Delay) can help lower the risk of dementia, even if you start later in life.

Key Findings on the MIND Diet and Dementia Risk:

  1. Beneficial at Any Age – Studies indicate that adopting the MIND diet, even in midlife or later, is associated with a slower rate of cognitive decline and reduced Alzheimer’s risk.
  2. Combination of Mediterranean and DASH Diets – The MIND diet emphasizes brain-healthy foods like leafy greens, berries, nuts, whole grains, and fish while limiting red meat, butter, cheese, and fried foods.
  3. Strongest Evidence for Long-Term Adherence – The longer and more consistently you follow the MIND diet, the greater the potential protective effects. However, even moderate adherence has shown benefits.
  4. May Reduce Dementia Risk by Up to 53% – Some studies found that strict adherence to the MIND diet was linked to a significantly lower risk of Alzheimer’s disease.

When Should You Start?

  • Midlife (40s-60s): Helps build cognitive resilience before significant age-related decline.
  • Later in Life (60s+): Still beneficial for slowing cognitive deterioration.

Heavy cannabis use may raise the risk of dementia by 72%.

Heavy cannabis use may raise the risk of dementia by 72%.

Comments 0 Comment

The claim that heavy cannabis use could increase dementia risk by 72% likely stems from a study or media report linking chronic, high-dose cannabis consumption to cognitive decline. However, the relationship between cannabis use and dementia is complex and not yet fully understood. Here’s what current evidence suggests:

Key Considerations:

  1. Study Limitations
    • If this figure comes from a specific study, it’s important to scrutinize its design (e.g., observational vs. controlled, sample size, duration). Many studies on cannabis and dementia rely on self-reported data or small cohorts, which can introduce bias.
    • Correlation does not equal causation—other factors (e.g., alcohol use, mental health conditions, socioeconomic status) may contribute to both heavy cannabis use and dementia risk.
  2. THC and Cognitive Effects
    • Heavy, long-term cannabis use (especially high-THC products) has been associated with memory deficits, reduced executive function, and lower hippocampal volume (a brain region critical for memory).
    • Animal studies suggest THC may accelerate amyloid plaque formation (a hallmark of Alzheimer’s), but human data is inconclusive.
  3. Dose and Frequency Matter
    • The 72% risk increase (if accurate) likely applies to heavy users (e.g., daily or near-daily use over years). Occasional or moderate use may not carry the same risk.
    • Early, frequent use (e.g., adolescence) may pose greater risks due to the brain’s developmental stage.
  4. Conflicting Research
    • Some studies find no significant link between cannabis and dementia after adjusting for confounders.
    • A 2023 study in Preventive Medicine even suggested that low-THC/high-CBD cannabis might have neuroprotective properties, though this remains debated.

While heavy cannabis use might elevate dementia risk for some individuals, the 72% figure should be interpreted cautiously. More longitudinal, high-quality research is needed to clarify this relationship. If you’re concerned about cognitive health, discuss cannabis use patterns with a healthcare provider, especially if you have other risk factors (e.g., family history of dementia)
