Aging, dementia and automobile driving

According to Norwegian law, drivers 70 years and older must carry a health certificate. This is issued by a general practitioner. If the patient is not supposed to drive because of a medical condition, the doctor should report this to the County Health Officer. This can be problematic, not only because assessing whether a patient fulfills the criteria for driving is difficult, but also because the doctor has obligations to both the public and his patient. These problems are discussed, based on assessment of available literature and on personal experience. Dementia is common in old age and affects approximately 15% of persons aged 75 and older. Patients with moderate and severe dementia should certainly not drive. However, some patients with mild dementia can nevertheless be safe drivers. The problem, however, is to identify the safe drivers among patients with mild dementia. The current regulations on dementia and driving are presented briefly.
