A Simple, Targeted Exercise Can Reduce Alzheimer’s Risk

Alzheimer’s disease affects millions of older adults worldwide, and this number is expected to double by 2060. However, research has shown that certain steps, including specific types of exercise, can help lower the risk of developing dementia.

Recent studies have revealed that dual-task exercises, in particular, provide greater benefits in fighting dementia.

Dual-Task Exercises

In this context, physical therapist Dr. Heather Sandison emphasized the importance of dual-task exercises, explaining that this type of workout involves engaging both the body and the mind cognitively.

For example, walking while conversing with another person can be considered a form of dual-task exercise.

A study published in 2022 in the journal Alzheimer’s Disease investigated how dual-task training—activities that combine physical movement with mental challenges—affects older adults experiencing cognitive decline.

The study’s results showed that participating in two to five sessions per week, each lasting between 30 and 120 minutes, led to significant improvements in memory, attention, problem-solving, balance, and walking speed.

Remarkably, researchers also found that these exercises reduced levels of beta-amyloid, a protein associated with Alzheimer’s disease.

Coordination of Movement and Focus

Researchers explain that this type of exercise forces the brain to process information, coordinate movements, and maintain focus simultaneously.

This simultaneous demand activates multiple brain networks, strengthens neural connections, and enhances neuroplasticity—the brain’s ability to adapt and form new pathways. Over time, this mental and physical synergy may help preserve cognitive skills and physical independence, making it a valuable tool for dementia prevention.

However, experts strongly emphasize that there is no single method guaranteed to protect against Alzheimer’s disease. Only through a regular combination of dual-task exercises, a balanced diet, social engagement, and management of health conditions like hypertension and diabetes can the risk be reduced.

Studies indicate that approximately 35% of dementia risk factors are modifiable, including midlife hypertension, obesity, smoking, social isolation, hearing loss, depression, diabetes, and physical inactivity.
