Alzheimer's disease: lifestyle factors and early language warning signs

Medical experts are highlighting the importance of lifestyle and early linguistic indicators in managing Alzheimer's disease. In France, between 1 and 1.4 million people live with Alzheimer's or related disorders, with approximately 225,000 new diagnoses annually.

Neurologists suggest that for the vast majority of late-onset cases—estimated at over 95%—lifestyle factors such as diet, vascular health, physical activity, and tobacco or alcohol use play a more significant role than genetics. The World Health Organization indicates that up to 45% of dementia risk could be avoided or delayed through these lifestyle interventions.

Beyond diet, subtle changes in language can serve as early warning signs before significant memory loss occurs. Key indicators to monitor include frequent pauses mid-sentence, the use of vague vocabulary (such as “thing” or “stuff”), difficulty naming familiar objects (anomia), semantic substitutions (e.g., saying “knife” instead of “fork”), and a general decrease in speech speed or structural coherence.
