Driving is considered a critical life skill and is closely associated with independence, allowing you to travel anywhere without relying on others. Driving requires precise coordination between the brain, eyes, hands, and legs, along with attention, judgement, and quick decision-making. This means that subtle changes in a person’s driving habits should be inspected closely, as they may give a glimpse into their cognitive health .
Let’s understand from a specialist why driving habits are not simply a matter of personal choice, such as deciding whether to drive fast or slowly, take a shortcut, or stick to familiar routes. In some cases, subtle changes in these habits demonstrate the earliest effects of changes happening within the brain . Dr J D Mukherji, chairman and head of neurology at Max Super Speciality Hospital, Saket, New Delhi, spoke about the possible connection between changes in driving habits and Alzheimer’s disease.
Researchers found that individuals with biological markers associated with preclinical Alzheimer’s disease showed a gradual increase in unsafe driving behaviours over time, despite not having noticeable cognitive symptoms. Finally, the expert highlighted the study findings that demonstrate that changes in driving behaviour may emerge years before memory problems become clinically apparent, providing another window for recognising early changes in the brain. Since there is currently no cure, much of the focus remains on early detection. As per the neurologist, one of the most concerning characteristics of this neurodegenerative condition is that it develops slowly over many years.

The neurologist cited a study published in Alzheimer’s & Dementia on November 23, 2022, which examined whether changes in driving behaviour could occur before noticeable cognitive symptoms or a formal Alzheimer’s diagnosis. He elaborated on the findings of the study, “It examined natural driving patterns among 137 cognitively normal adults aged 65 years and above using vehicle monitoring systems. Alzheimer’s is a progressive disease, which means its symptoms gradually worsen over time.
