| Annotation | Dementia may contribute significantly to driving impairment commonly associated with older people. A brief, reliable and sensitive screening method to identify drivers who may have cognitive impairment due to Alzheimer's disease (AD) or other dementing illnesses is needed for settings including driver's licence renewing offices. Control and demented participants at the Washington University Alzheimer's Disease Research Center (ADRC) between March and November 1995 were evaluated for their ability to identify traffic signs correctly. After initially testing 39 traffic signs, 10 signs were selected based on scorer reliability and their ability to discriminate cognitively normal individuals from those with dementia. 66 cognitively normal people (average age 78) and 70 with dementia (average age 76) were tested. The Traffic Sign Naming Test successfully identified 74% of those with mild or moderate dementia of the Alzheimer type (DAT) from cognitively healthy older people of comparable age, sex, education and socio-economic status. 11% of the healthy drivers were misclassified as demented. The test may be useful in identifying older drivers in need of further assessment of their driving skills. (RH). |
