35% of the risk of dementia is linked to modifiable factors.

Walking while talking to someone is an important exercise for brain health       

Specific and simple exercise reduces the risk of Alzheimer's.

Alzheimer's disease affects millions of older adults worldwide, and this number is expected to double by 2060. However, research has shown that there are steps you can take to reduce the risk of dementia through specific types of exercise. New research has revealed that dual-task exercise, in particular, has greater benefits in combating dementia.

Dual-task exercise

In this context, physical therapist Dr. Heather Sandison emphasized the importance of dual-task exercise, explaining that this type of exercise requires engaging the body cognitively and mentally. For example, walking while talking to someone else can be a form of dual-task exercise. A 2022 study published in the Journal of Alzheimer's Disease investigated how dual-task training, activities that combine physical movement with mental challenges, affects older adults with cognitive decline.

The study's findings revealed that two to five weekly sessions, each lasting 30 to 120 minutes, led to significant improvements in memory, attention, problem-solving, balance, and walking speed. Surprisingly, the researchers discovered that it reduced levels of beta-amyloid, a protein associated with Alzheimer's disease.

Simultaneous coordination of movement and concentration

The researchers explain that this type of exercise forces the brain to simultaneously process information, coordinate movement, and maintain focus. This simultaneous demand also activates multiple brain networks, strengthens neural connections, and promotes neuroplasticity, the brain's ability to adapt and form new pathways. Over time, this mental-physical synergy can help maintain both cognitive skills and physical independence, making it a valuable tool for dementia prevention.

However, experts strongly emphasize that no single habit guarantees protection against Alzheimer's disease. Only by regularly combining dual-tasking exercise with other healthy choices, such as a balanced diet, social engagement, and managing health conditions such as high blood pressure and diabetes, can the risk of developing Alzheimer's be reduced.

Studies have found that approximately 35% of the risk of dementia is linked to modifiable factors, such as middle-aged high blood pressure, obesity, smoking, social isolation, hearing loss, depression, diabetes, and physical inactivity.
