For which diagnosed neurological condition is a driver considered medically unqualified for driving?

A driver diagnosed with dementia is deemed medically unqualified for driving primarily due to the cognitive impairments associated with the condition. Dementia affects memory, reasoning, and judgment, which are essential for safe driving. Individuals with dementia may experience confusion, impaired decision-making abilities, and lapses in awareness, all of which significantly increase the risk of accidents on the road.

In contrast, a history of a subarachnoid hemorrhage five years ago and transient ischemic attacks that occurred over a year ago may not automatically disqualify a driver, especially if they have since recovered and do not exhibit any ongoing symptoms. Medical assessments regarding these conditions consider the individual's current health status, how well they have managed their recovery, and whether they are still experiencing any neurological deficits. Thus, these conditions do not uniformly render a driver medically unqualified, making dementia the key factor in this question.
