Dr. Omobolanle Ayo, a specialist in cognitive health, has emphasised the role of lifestyle strategies in reducing the risk of dementia, including Alzheimer’s disease, which often runs in families. Her work combines clinical practice with community education, advocating for prevention to be given as much attention as treatment.

“Dementia doesn’t just happen overnight,” Dr. Ayo explained. “It is often the result of small, cumulative changes in the brain and body over decades. But the good news is we can influence many of those changes through lifestyle.”

Drawing on her clinical experience, Dr. Ayo underlined the importance of early intervention. She recommends consistent physical activity, a balanced diet, and mental stimulation to support brain health.

“The brain thrives on engagement,” she said. “Activities that challenge memory, language or coordination—such as learning a new instrument, dancing, or social interaction—help strengthen neural connections.”

Evidence supports her approach. Studies indicate that up to 40 per cent of dementia cases could potentially be delayed or prevented by addressing modifiable factors such as hypertension, obesity and physical inactivity.
Dr Ayo suggests this proportion could increase further if individuals adopt small, sustained habits from an early age.

“We often underestimate the power of prevention because its results are not immediate,” she observed. “But every healthy habit—better sleep, proper nutrition, stress management—is a brick in the wall protecting the brain.”

Through community outreach, Dr Ayo seeks to make scientific knowledge accessible. “Science should never be distant from the people it aims to help,” she said. “That is why I am passionate about translating these findings into something people can use daily.”

Her work also addresses cultural attitudes, noting that dementia is often misunderstood or stigmatised in African societies. Early recognition by families, she explained, enables timely intervention, which can significantly alter outcomes.

Dr Ayo continues to advocate for programmes that promote healthier diets, physical engagement, and social activity among older adults.

“When people realise that boosting brain health is within reach, hope replaces fear,” she added. “That is when real change begins.”
