A new study published in The Lancet Public Health has shown that daily walking can significantly reduce the risk of cognitive decline, particularly among individuals genetically predisposed to Alzheimer’s disease. Researchers found that consistent walking was associated with a lower risk of serious health issues, including dementia.
Doctors in the UAE emphasize the benefits of walking, highlighting its positive impact on cardiovascular health and blood flow to the brain. Walking stimulates brain-derived neurotrophic factor (BDNF), which supports neuron growth and survival, helping maintain memory and cognitive function.
“Daily walking among older adults helps maintain cognitive function and delays dementia,” said Dr Noha Abdulwahid, Specialist Neurology at Medcare Royal Specialty Hospital. She added that individuals carrying the APOE e4 gene variant may experience even greater benefits.
Experts recommend around 7,000 steps per day to lower the risk of chronic diseases and cognitive decline. “At least 35 minutes per week of moderate-to-vigorous walking can reduce dementia risk by up to 41 percent,” Dr Abdulwahid noted.
Alzheimer’s disease is the most common form of dementia in the UAE and a growing public health concern. Dr Poonam C. Awatare of International Modern Hospital Dubai said the country spends an estimated US$1.35 billion annually on dementia care. Across the MENA region, dementia cases are projected to rise by 367 percent by 2050.
Personal stories underscore the disease’s impact. Anam Rizvi described how her mother gradually lost memory and recognition of family members. Similarly, Rami Abadi recalled his father struggling with coordination, balance, and frequent falls due to Alzheimer’s.
Lifestyle choices, including walking, diet, and mental engagement, can help mitigate these risks. Dr Asma Mushtaque of Burjeel Medical Center recommended daily walking to control blood pressure, diabetes, and cholesterol, all linked to dementia. She also suggested a Mediterranean-style diet, adequate vitamin D, regular cognitive activity, and sufficient sleep.
Exercise supports brain health by stimulating neurotrophic factors, enhancing synaptic plasticity, and reducing inflammation and oxidative stress, said Dr Awatare. Even modest activity, such as 3,800 steps per day or five extra minutes of walking, can significantly lower dementia risk.
Walking for 30 minutes most days is an effective starting point. Combining walking with resistance, balance, and flexibility exercises, alongside mental stimulation, healthy diet, and stress management, offers comprehensive protection for brain function.
“Walking is one of the easiest, safest, and most cost-effective ways to support brain health,” Dr Awatare said. While it cannot fully prevent Alzheimer’s, evidence shows it can delay onset, slow cognitive decline, and complement other lifestyle strategies.
