Understanding Alzheimer’s: Building Awareness and Supporting Cognitive Health

For seniors and caregivers, learning about Alzheimer’s can feel overwhelming. However, understanding the condition, recognizing early signs, and educating ourselves on research-backed strategies can help families feel more prepared. 

What Is Alzheimer’s Disease?

Alzheimer’s is the most common cause of dementia, making up 60-80% of cases. It’s a brain disorder that progresses slowly through three main stages: early, middle, and late. While unique to each individual, the disease typically begins with mild memory lapses and gradually progresses to affect thinking, behavior, and daily life. Individuals can lose the ability to respond to their environment, carry on conversations, and eventually lose control of their movement, requiring around-the-clock care. 

The Alzheimer’s Association identifies 10 warning signs that may indicate Alzheimer’s or other dementias: 

• Memory loss that disrupts daily life 
• Challenges in planning or solving problems 
• Difficulty completing familiar tasks 
• Confusion with time or place 
• Trouble understanding visual images and spatial relationships 
• New problems with words in speaking or writing 
• Misplacing things and losing the ability to retrace steps 
• Decreased or poor judgment 
• Withdrawal from work or social activities 
• Changes in mood and personality 

If you or a loved one experience several warning signs, see a healthcare provider for evaluation. Early detection helps families plan and access support services. 

The Numbers Behind Alzheimer’s

According to the Alzheimer’s Association, over 7 million Americans currently live with Alzheimer’s disease. This number is expected to grow to nearly 13 million by 2050. About 1 in 9 people age 65 and older have Alzheimer’s disease. 

Nearly 12 million family members and caregivers provide unpaid care for people with dementia. In 2024, these caregivers provided 19 billion hours of care valued at more than $413 billion. Women are particularly affected, making up almost two-thirds of both Alzheimer’s patients and caregivers. 

While these numbers seem overwhelming, research offers hope. Studies suggest that certain lifestyle choices may play a role in supporting cognitive well-being. 

Understanding Cognitive Well-Being & Brain Health

Cognitive well-being includes more than memory. It covers our ability to think clearly, process information, make decisions, and stay focused during daily activities. While some cognitive changes are normal with aging, research suggests staying active and engaged may help support brain function. 

Research also shows that several lifestyle factors may support brain health. These strategies can’t guarantee protection, but studies suggest they may help maintain brain function. 

Physical activity  

Regular physical activity is a consistent recommendation from healthcare providers as a way to protect our brain health. Regular physical activity can reduce your risk of cognitive decline and dementia, according to the Centers for Disease Control and Prevention. Research from the University of British Columbia found that regular aerobic exercise appears to boost the size of the hippocampus, the brain area involved in verbal memory and learning. For seniors, moderate activities performed consistently, like walking, swimming, or gardening, may offer additional benefits to brain health. 

Mental stimulation  

Keeping the brain active through learning and challenges may help maintain function. This includes reading, puzzles, games, learning new skills, and creative activities. The key is finding engaging activities that provide appropriate challenges. 

Quality sleep  

Sleep plays a crucial role in brain health. During sleep, the brain clears waste products and forms memories. Creating good sleep routines and comfortable environments benefits both seniors and caregivers. 

Social connections  

Strong social relationships may help protect against cognitive decline. Regular interaction with family, friends, and community provides mental stimulation and emotional support that may benefit brain health. 

Best Foods for Brain Health

Current evidence suggests that heart-healthy eating may also help protect the brain, according to the Alzheimer’s Association. However, it’s important to understand that much of our current evidence comes from large studies that can show an association between factors and outcomes but cannot prove cause and effect. 

Heart-healthy eating includes limiting the intake of sugar and saturated fats and making sure to eat plenty of fruits, vegetables, and whole grains. No one diet is best. The Alzheimer’s Association notes that two diets that have been studied and may be beneficial to lowering the risk of Alzheimer’s are the DASH (Dietary Approaches to Stop Hypertension) diet and the Mediterranean diet. 

Diets that may support brain health: 

The DASH diet emphasizes vegetables, fruits, fat-free or low-fat dairy products, whole grains, fish, poultry, beans, seeds, nuts, and vegetable oils. The DASH diet limits sodium, sweets, sugary beverages, and red meats. 

The Mediterranean diet includes relatively little red meat. It emphasizes whole grains, fruits and vegetables, fish and shellfish, and healthy fats like nuts and olive oil. 

It’s important to remember that insights about potentially modifiable risk factors apply to large population groups, not to individuals. While these dietary patterns show promise in research, more large-scale studies are needed to definitively establish their role in brain health. 

Creating Supportive Environments

Supporting cognitive health includes creating environments that promote both safety and stimulation. Good lighting, organized spaces, and areas for different activities can make meaningful differences. For caregivers, this means balancing safety with independence. 

Having conversations early about future care preferences allows individuals and families to make important decisions together. These discussions, though emotionally challenging, can reduce anxiety for everyone involved, help families prepare for different possibilities, and improve quality of life for both the person with Alzheimer’s and their loved ones. Early planning empowers individuals to express their values and wishes, ensuring their voice remains central to their care throughout the disease journey. 

Understanding Alzheimer’s and cognitive health provides the foundation for informed decisions. While we can’t control every factor affecting brain health, daily choices can have a positive influence on cognitive function as we age. 

For seniors, this means considering how activities, food choices, and social connections might support cognitive well-being. For caregivers, it means creating supportive environments that honor independence while promoting engagement. 

Hope Through Research and Progress 

This is truly a time of unprecedented promise in Alzheimer’s research. Scientists have made remarkable progress in understanding the disease, and the pace of discovery continues to accelerate. The Alzheimer’s Association is currently investing $450 million in over 1,200 active research projects across 56 countries, representing the largest nonprofit funding commitment to Alzheimer’s research worldwide. 

Recent breakthroughs include: 

• Earlier diagnosis: New blood-based biomarker tests may soon allow doctors to detect Alzheimer’s changes years before symptoms appear. 
• Treatment advances: The first disease-modifying drugs have been approved by the FDA, offering hope for slowing cognitive decline in early stages. 
• Prevention research: Large-scale studies are revealing how lifestyle interventions may help reduce risk and protect brain health. 
• Clinical trials: Over 170 studies are currently testing new treatments, with more than three-quarters focused on potentially disease-modifying therapies. 

Additionally, a study conducted by U.S. Pointer recently demonstrated that comprehensive lifestyle interventions targeting nutrition, physical activity, cognitive engagement, and health monitoring can improve cognition in older adults at risk for cognitive decline. 

While we don’t yet have a cure, each research milestone brings us closer to ending Alzheimer’s disease. By staying informed about these developments and supporting ongoing research efforts, families can maintain hope while taking proactive steps to support brain health. The scientific community’s dedication to finding answers continues to grow, offering genuine reasons for optimism about the future.
