Why a Brain Health Audit Is Worth Your Time

Most people schedule an annual physical to catch cardiovascular and metabolic risks early. Cognitive health deserves the same proactive attention — yet few of us formally review the lifestyle factors that shape how our brains age. This checklist is designed to fill that gap.

The science of brain aging has matured considerably. Researchers now estimate that roughly 40 percent of dementia cases worldwide may be linked to modifiable risk factors, according to the Lancet Commission on Dementia Prevention, Intervention, and Care. That doesn't mean any individual can guarantee they'll avoid cognitive decline, but it does mean that daily habits carry real weight over time.

If you're new to thinking about this systematically, our evidence-informed starting point on brain health covers the foundational science. This checklist is the practical companion — a structured way to audit where you stand and identify gaps worth discussing with your doctor.

Work through each section honestly. The goal isn't to achieve a perfect score; it's to surface one or two areas where targeted change is both realistic and beneficial.

What You'll Need Before You Begin

This audit requires no equipment or medical tests. You'll get more out of it if you have a few things on hand:

Optional

Recent lab results or health summary

Allows you to check blood pressure, cholesterol, and blood glucose values as you work through the cardiovascular section.

Required

Notebook or digital notes app

Use to record flagged items, follow-up questions, and habit gaps you want to discuss with your provider.

Optional

Current medication list

Helps you review whether any medications you take are associated with cognitive side effects — a question worth raising with your doctor.

Set aside uninterrupted time — rushing through self-reflection produces less useful answers. Consider completing this audit near your annual physical so you can bring findings directly to your provider. Our annual checkup preparation checklist can help you organize questions to raise during that visit.

The Brain Health Checklist

Work through each group below. For every item, ask yourself honestly: Is this an area I'm actively managing, partially addressing, or neglecting? Note anything that prompts a follow-up question for your healthcare provider.

Sleep Quality

Confirm you're regularly getting 7–9 hours of sleep per night, as chronic short sleep is associated with accelerated cognitive aging. Must
Ask your doctor whether you should be screened for obstructive sleep apnea, particularly if you snore, wake frequently, or feel unrefreshed in the morning. Must
Review your sleep environment for light, noise, and temperature conditions that support consistent, uninterrupted rest. Should

Cardiovascular and Metabolic Health

Verify that your blood pressure has been checked within the past year and that readings are within a healthy range for your age. Must
Confirm that blood glucose and cholesterol levels have been assessed by your provider and that any concerns are being actively managed. Must
Discuss with your doctor whether your current cardiovascular health status requires any follow-up screening or lifestyle modification. Should

Physical Activity

Assess whether you're engaging in regular aerobic activity — current guidelines suggest at least 150 minutes of moderate-intensity movement per week for most adults. Must
Evaluate whether you're incorporating resistance or strength training at least twice a week, which supports both brain and metabolic health. Should
Note whether you spend long unbroken stretches sitting and consider whether introducing regular movement breaks is feasible. Should

Diet and Nutrition

Reflect on whether your overall eating pattern emphasizes vegetables, fruits, whole grains, legumes, and healthy fats — dietary patterns associated with reduced cognitive decline risk. Must
Assess your typical alcohol consumption and discuss any concerns with a healthcare provider, as heavy drinking is a documented risk factor for cognitive impairment. Must
Consider whether your diet is high in ultra-processed foods and refined sugars, which emerging research links to poorer brain health outcomes. Should

Mental Stimulation and Social Engagement

Evaluate whether your daily life includes intellectually stimulating activities — reading, learning new skills, creative pursuits, or complex problem-solving. Should
Assess the quality and frequency of your meaningful social connections, as chronic loneliness and social isolation are linked to elevated dementia risk. Must
Identify whether you have at least one community, group, or relationship that provides regular, purposeful social interaction. Should

Stress and Mental Health

Reflect honestly on your chronic stress levels and whether you have reliable, effective strategies for managing them. Must
Screen yourself informally for symptoms of depression or anxiety, recognizing that both are associated with increased dementia risk and are treatable conditions — then discuss findings with a provider. Must
Consider whether mindfulness, relaxation practices, or professional counseling might be beneficial given your current stress load. Nice to have

Sensory Health and Environmental Risk Factors

Confirm that your hearing has been assessed within the past two years — untreated hearing loss is now recognized as a modifiable risk factor for cognitive decline. Must
Verify that your vision is being regularly checked and corrected, as sensory impairment can limit the cognitive stimulation that comes from reading and social interaction. Should
Review any medications you take regularly and ask your provider whether any carry known risks for cognitive function, particularly in older adults. Nice to have

This Checklist Is Not a Diagnostic Tool

No self-audit can diagnose cognitive impairment or predict individual health outcomes. If you or a family member have noticed meaningful changes in memory, language, judgment, or daily functioning, consult a qualified healthcare professional promptly — do not rely on a checklist as a substitute for clinical evaluation. Likewise, if you flag concerns in multiple areas, bring them to your doctor rather than acting on them independently.

Making Sense of Your Results

After working through the checklist, you'll likely notice a pattern: a few areas where your habits are solid, and one or two where there's meaningful room to improve. Resist the urge to overhaul everything at once. Research on behavior change consistently shows that focusing on one or two high-leverage shifts — and sustaining them — outperforms broad but shallow attempts at change.

If you flagged concerns around hearing, it's worth reading about why untreated hearing loss is now considered a modifiable risk factor for cognitive decline. If physical mobility or exercise came up as a gap, our mobility self-check for adults over 55 offers a complementary assessment.

Finally, bring this audit to your next annual physical. A clinician can interpret your flagged items in the context of your personal and family history in ways no checklist can replicate.
