Seniors

runs a red light, is T-boned by another vehicle and is arrested for DUI because the investigating officer determines she is "impaired" and possibly under the influence of a narcotic. (she was not!) A night in jail for a person with dementia is not an ideal situation, to say nothing of the costs involved in proving their innocence!

Getting lost is certainly a concern .... most communities have "Project Life Saver" bracelets available for the person to wear, so the authorities can track them in case they do get lost.

Driving in fact can be a very immediate threat for an impaired individual. If the illness progresses taking the keys is a must, sooner rather then later, before something disastrous occurs.
