How Exercise Could Help Slow Alzheimer’s Progression (Updated July 2025)

When someone you love is diagnosed with Alzheimer's, you want to do everything possible to help. The good news? Research shows that something as simple as regular movement can make a real difference in slowing cognitive decline and improving quality of life.

A 2025 Johns Hopkins study of nearly 90,000 adults found that just 35 minutes of weekly exercise reduces dementia risk by 41%—and the benefits keep growing from there. Even more encouraging, researchers have identified the optimal "dose" of exercise for cognitive benefits: about 150 minutes of moderate activity per week, like brisk walking.

This isn't about becoming a fitness fanatic overnight. It's about finding ways to add meaningful movement to daily life, even when Alzheimer's makes everything feel more complicated.

What Exercise Does for the Brain

The amazing chemistry of movement

When someone with Alzheimer's exercises, remarkable changes happen in their brain. Physical activity triggers a surge in brain-derived neurotrophic factor (BDNF)—think of it as fertilizer for brain cells. This boost helps create new neurons in the hippocampus, the brain's memory center. Stanford research shows that exercise uniquely combines multiple brain-protecting mechanisms in ways that nothing else can replicate.

Exercise also releases beneficial molecules called "exerkines" that cross into the brain and help clear out toxic proteins associated with Alzheimer's. At the same time, it shifts the brain's immune system from an inflammatory state to a healing one, actively working to protect brain cells and connections.

Better blood flow, clearer thinking

One of exercise's most important benefits is improving blood flow to the brain. In Alzheimer's patients, the blood-brain barrier—which normally protects the brain—often becomes leaky. Regular physical activity helps maintain this crucial barrier while ensuring the brain gets the oxygen and nutrients it needs to function at its best.

Finding the Right Exercise for Each Stage

Early-stage Alzheimer's: Building habits while you can

In the early stages, when someone still has most of their physical abilities, the goal is establishing sustainable exercise habits. The prescription is straightforward: 150 minutes of moderate activity weekly plus some strength training twice a week.

This could be daily 20-30 minute walks, swimming at the local pool, or joining a senior fitness class. Group activities work particularly well because they combine physical movement with social interaction—both crucial for brain health.

Middle-stage adaptations: Keeping it simple

As cognitive abilities decline, exercise needs to become simpler and more structured. Sessions might be shorter—20-30 minutes—with familiar activities in familiar places. Chair-based exercises, supported walking, and gentle movement to favorite music often work well.

The key is routine. Same time, same place, same activities. This predictability reduces anxiety and makes participation more likely.

Late-stage support: Movement as comfort

In advanced stages, exercise becomes about comfort and connection rather than fitness goals. Even 10-15 minutes of gentle stretching, assisted standing, or swaying to music can provide benefits. Success is measured in moments of calm engagement rather than physical improvements.

Types of Exercise That Help Most

Walking: The simple superstar

Don't underestimate the power of a daily walk. It's accessible, requires no special equipment, and provides both physical and mental benefits. For someone with early-stage Alzheimer's, walking the same route daily can become a comforting routine. As abilities change, walks can be shortened or supported with walking aids.

Tai Chi: Moving meditation

Tai Chi showed remarkable results in recent studies, with participants showing cognitive improvements equivalent to reversing 6 years of decline. This gentle, flowing exercise combines movement, breathing, and meditation in ways that seem particularly beneficial for people with dementia.

Dancing: Joy in movement

Dance therapy demonstrated a 76% reduction in dementia risk in long-term studies. Whether it's ballroom dancing, folk dancing, or simply moving to favorite songs in the living room, dance combines physical activity with music, memory, and often social interaction.

Strength training: Maintaining independence

Twice-weekly resistance training using light weights, resistance bands, or bodyweight exercises helps maintain the muscle strength needed for daily activities. This doesn't mean intense workouts—simple exercises like seated leg lifts or wall push-ups can make a difference.

Making Exercise Safe and Enjoyable

Creating a safe environment

Safety is paramount when someone has cognitive impairment. Remove trip hazards like loose rugs, ensure good lighting, and create clear pathways for movement. If someone tends to wander, channeling that energy into purposeful walking in safe spaces can be beneficial.

For outdoor activities, consider GPS tracking devices and always ensure proper identification is worn. Create familiar routes that naturally loop back to the starting point.

The art of motivation

Getting someone with dementia to exercise requires creativity and patience. Never ask, "Do you want to exercise?"—the answer is usually no. Instead, try statements like "It's time for our walk" or frame activities around past interests. The former gardener might enjoy "checking the flowers" while doing squats.

Music is incredibly motivating. Play favorite songs from their younger years during movement activities. One study found that participants' daily walks became so routine they happened "automatically," requiring no conscious decision.

Programs That Work

Professional programs

Mayo Clinic's HABIT program combines physical activity with cognitive training and is covered by Medicare. The Otago Exercise Programme, designed to prevent falls, shows impressive results with 35-40% reduction in falls among participants.

Community resources

Many YMCAs offer specialized classes for people with cognitive impairment. Adult day programs often integrate movement throughout the day. SilverSneakers, available through many Medicare Advantage plans, provides access to fitness classes and online programs designed for older adults.

Technology helpers

Virtual options expanded during the pandemic and continue to offer accessibility. Apps can provide guided exercises, though they typically need caregiver support for setup. The key is finding technology that helps rather than complicates daily life.

Supporting the Caregiver

You're in this together

Caregiving is exhausting, and adding exercise to an already overwhelming schedule might seem impossible. But here's the thing: when you exercise together, everyone benefits. The person with dementia gets physical activity and social connection, while you get stress relief and better health to sustain your caregiving journey.

Managing challenges

When resistance occurs—and it will—try indirect approaches. Start by exercising nearby and gradually invite participation. If agitation happens during activity, redirect to something calming and try again later. Sometimes breaking exercise into several 5-minute sessions works better than longer periods.

Real caregivers report that establishing movement routines reduced wandering behaviors and improved mood for the rest of the day. One husband described how his wife felt proud to "keep up" with him on walks, transforming potential resistance into partnership.

Understanding Medicare Coverage

What's covered

Medicare covers medically necessary physical and occupational therapy with no annual limits. After meeting your deductible, you pay 20% of costs. The key is having proper documentation linking exercise to specific medical needs—not just "general fitness" but "fall prevention" or "gait training."

Medicare Advantage plans often include fitness benefits like SilverSneakers, providing access to thousands of fitness locations and specialized classes for seniors.

Making the most of benefits

Work with healthcare providers to document how exercise addresses specific medical needs. Physical therapists can design home exercise programs and teach family members safe techniques. Occupational therapists can adapt exercises to support daily living activities.

The Social Side of Movement

Exercise as connection

Group exercise programs consistently show better outcomes than solo activities. Participants describe "pleasant social situations" where they can "laugh and tell jokes" while moving. The shared experience of managing challenges reduces isolation and creates meaningful connections.

Even simple programs pairing people with dementia with volunteers or intergenerational activities can provide motivation that keeps people moving when everything else feels difficult.

Looking Forward

The research continues

Scientists are exploring personalized exercise programs based on genetic factors and biomarkers. New research into "exercise mimetics"—medications that replicate some benefits of physical activity—offers hope for those who can't exercise traditionally.

But researchers emphasize that nothing replaces actual movement when it's possible. The human connection, the sense of accomplishment, and the immediate mood benefits of real physical activity remain irreplaceable.

How a Solace Advocate Can Support Your Exercise Journey

Creating and maintaining an exercise routine for someone with Alzheimer's can feel overwhelming—especially when you're already managing doctor appointments, medication schedules, and daily care needs. This is where a Solace advocate becomes invaluable.

Your exercise coordinator and cheerleader

A Solace advocate can help you develop a realistic exercise plan that fits your loved one's current abilities and your family's schedule. They understand both the medical benefits of physical activity and the practical challenges families face. Your advocate can research local programs, connect you with dementia-friendly fitness classes, and even help you understand which activities Medicare might cover.

When your loved one resists exercise—and most do at some point—your advocate has strategies that work. They've seen what motivates people in similar situations and can suggest creative approaches you might not have considered. Maybe it's finding the right music, timing activities around medication schedules, or connecting exercise to cherished memories.

Navigating insurance and resources

Understanding what Medicare covers for exercise-related services can be confusing. Your Solace advocate can explain your benefits, help you get referrals for physical or occupational therapy, and work with your healthcare team to document medical necessity for coverage. They can also help you appeal denied claims—with Solace's 54% success rate in overturning insurance denials.

Beyond insurance, advocates know about community resources you might not discover on your own. They can connect you with local support groups where other families share exercise tips, find transportation services for getting to fitness programs, or locate specialized equipment that might help your loved one stay active safely.

Supporting the whole family

Your advocate understands that caregiver wellbeing directly impacts your loved one's care. They can help you find respite services so you can attend exercise classes together, connect you with caregiver support groups, or simply provide emotional support when establishing new routines feels impossible.

When health changes require adjusting exercise plans, your advocate helps coordinate between doctors, therapists, and family members to ensure everyone stays on the same page. They attend appointments virtually when needed, ask the right questions about exercise safety, and help translate medical recommendations into practical daily activities.

Making it sustainable

Perhaps most importantly, a Solace advocate helps make exercise a sustainable part of your family's routine rather than another stressful obligation. They work with you long-term, adjusting approaches as needs change and celebrating small victories along the way. Because when exercise becomes a source of connection and joy rather than conflict, everyone benefits.

A Message of Hope

Here's what the research tells us clearly: exercise is one of the most powerful tools we have against Alzheimer's disease. The optimal amount is about 150 minutes of moderate activity weekly, but even 35 minutes provides significant benefits. More importantly, it's never too late to start, and every movement counts.

This isn't about perfection or becoming an athlete. It's about finding moments of joyful movement that honor the person's abilities and preferences. Whether it's dancing to beloved songs, walking in a favorite park, or doing gentle stretches while watching TV, each moment of activity is a victory.

For families facing Alzheimer's, remember: you don't have to do this alone. Healthcare providers, community programs, and Medicare benefits can all support your efforts to keep your loved one moving. Exercise isn't just medicine for the body—it's a way to maintain connection, dignity, and quality of life throughout this challenging journey.

Every step matters. Every movement is meaningful. And there's always hope in motion.

FAQ: Frequently Asked Questions About Exercise and Alzheimer’s Disease

Can exercise slow the progression of Alzheimer’s disease?

Yes, physical exercise may help slow the progression of Alzheimer’s disease, particularly in its early stages. While it won’t reverse cognitive decline, regular movement appears to enhance memory, mood, and daily function. This effect is likely due to increased synaptic plasticity, improved blood flow to the brain, and the reduction of neuroinflammation. Studies suggest that exercise also helps promote the clearance of amyloid beta, a protein linked to plaque buildup in Alzheimer’s, and supports mitochondrial health through biological pathways like sirt1-foxo1/3-pink1-parkin.

What are the benefits of aerobic exercise for Alzheimer’s patients?

Aerobic exercise such as walking, swimming, or cycling increases blood circulation and oxygen delivery to the brain. This helps maintain brain volume and supports neurogenesis, particularly in the hippocampus, which governs memory. Aerobic activity is also associated with elevated levels of brain-derived neurotrophic factor (BDNF), which protects neurons and promotes new connections. For individuals with Alzheimer’s disease, aerobic exercise has been shown to improve attention, mood, and mental flexibility while also enhancing cardiovascular health.

Is strength training helpful for cognitive function in Alzheimer’s?

Strength training supports cognitive function by improving executive skills such as planning and attention. This type of exercise has been linked to increased muscle mass, which contributes to the release of irisin, a hormone associated with hippocampal growth and neurogenesis. Additionally, resistance training enhances insulin sensitivity and mitochondrial function—two areas frequently impaired in Alzheimer’s disease. Studies also indicate that strength training can help maintain independence, which has profound psychological benefits for patients.

How does physical exercise reduce the risk of developing Alzheimer’s?

Exercise contributes to dementia prevention through multiple mechanisms. It enhances vascular health by promoting angiogenesis and maintaining the integrity of the blood-brain barrier. Regular physical activity reduces systemic inflammation and oxidative stress, both of which are tied to Alzheimer’s progression. It also increases protective factors like NGF and BDNF that help neurons thrive. Starting an exercise habit even in midlife significantly reduces the likelihood of developing Alzheimer’s later on, according to long-term cohort studies.

What are the recommended physical activity levels to prevent dementia?

For dementia prevention, health authorities such as the World Health Organization recommend at least 150 to 300 minutes of moderate-intensity aerobic activity per week, or 75 to 150 minutes of vigorous-intensity aerobic activity. Strength training should also be included at least twice a week, and older adults are encouraged to integrate exercises that enhance balance and coordination to prevent falls. These guidelines are aimed at adults over 65, but the benefits begin to accrue well before that age.

What types of balance and coordination exercises are best for Alzheimer's patients?

Exercises that challenge balance and coordination, like tai chi and yoga, are especially useful for Alzheimer’s patients because they promote both physical and mental agility. Simple tasks such as heel-to-toe walking, standing leg lifts, and navigating obstacle courses can help prevent falls and support motor memory. Activities that combine cognitive and physical tasks, like walking while conversing or playing movement-based games, also stimulate neural circuits and may contribute to slowing cognitive decline.

Is high-intensity interval training (HIIT) safe or beneficial for Alzheimer’s patients?

High-intensity interval training, or HIIT, has shown some promise in improving cardiovascular and cognitive function, even in older adults. It increases the production of vascular endothelial growth factor (VEGF), enhances mitochondrial performance, and may reduce oxidative stress. However, HIIT should only be pursued under medical supervision, especially for individuals with Alzheimer’s disease. Modified versions involving short bursts of activity followed by rest can provide benefits while minimizing risk. For most, low to moderate-intensity routines remain the safest and most sustainable.

Can swimming serve as therapy for individuals with Alzheimer’s?

Swimming is an excellent therapeutic exercise for those with Alzheimer’s disease. It provides low-impact, full-body movement that is easy on joints and helps improve circulation, flexibility, and mood. The repetitive nature of swimming can be calming, while the resistance of water offers mild strength training benefits. When performed in a safe, familiar setting, swimming can also reduce agitation and anxiety, contributing to a better emotional state and a greater sense of well-being.

When is the best time to start exercising to help prevent Alzheimer’s disease?

The most effective time to begin exercising for Alzheimer’s prevention is during midlife, typically between the ages of 40 and 60. Establishing an active lifestyle during this window appears to significantly lower risk. However, beginning to exercise at any age provides benefits. In early Alzheimer’s, physical activity can help maintain daily functioning and slow the rate of decline. Even in later stages, it contributes to better sleep, improved mood, and reduced behavioral symptoms. It is never too late to start.

Are there physical activity guidelines for caregivers of Alzheimer’s patients?

Caregivers should prioritize their own physical activity not only for personal health, but because their well-being directly affects the quality of care they provide. Moderate exercise helps caregivers manage stress, sleep better, and reduce the risk of burnout. Many caregivers benefit from participating in joint exercise routines with their loved ones, fostering shared engagement and mutual motivation. Guidelines recommend the same 150 minutes per week of moderate aerobic activity, and caregivers can explore local support networks that offer specialized group classes or respite-based fitness options.
