Background: Driving cessation is a likely consequence of progressive dementia. Patients and families can benefit from support through this transition, both to safeguard the patient and public and to help preserve healthy social activity of the patient., Methods: To provide appropriate supportive information, we developed a 35-page manual ('Supporting family caregivers of older drivers with dementia') available as a free download from our department website. We then informed municipal governments of its availability, tracked website access metrics, and followed up 7 months later with a postal survey to the heads of each municipal government's department of welfare for older citizens., Results: From February to September 2010, the manual was accessed 33 494 times. Of the 1750 municipalities sent surveys, we received 1067 responses (61%). The responses showed that 943 professionals (94.6%) were able to obtain information they needed from the manual, 247 (23%) had used the manual to help residents during the 7 months, and 89% of those who used the manual used it to provide relevant advice to family caregivers. The responses also showed that significantly more use occurred in towns and villages as opposed to cities, consistent with the limited public transportation options in smaller municipalities (P = 0.002)., Conclusions: We anticipate that use of this manual will raise general awareness of this social health issue and facilitate collaborations to provide more social support for those with dementia and their family members., (© 2017 Japanese Psychogeriatric Society.)

Background: Assessing driving aptitude in dementia patients is critically important for both patient and public safety. However, there have been only a few reports on the driving behaviours and accident risk of patients with dementia, especially frontotemporal lobar degeneration (FTLD). Therefore, we compared the characteristics of driving behaviours in patients with FTLD and those with Alzheimer's disease (AD)., Methods: The subjects were 28 FTLD and 67 AD patients who visited the Department of Psychiatry, Kochi Medical School Hospital. We conducted semi-structured interviews with their families and caregivers about traffic accident history and changes in patient driving behaviours after dementia onset and then compared the findings between the two groups., Results: Overall changes in driving behaviours were reported in 89% (25/28) and 76% (51/67) of the FTLD and AD patients, respectively (P = 0.17). In the FTLD group, difficulty in judging inter-vehicle distances, ignoring road signs and traffic signals, and distraction were reported in 50% (14/28), 61% (17/28), and 50% (14/28) of patients, respectively, and 75% (21/28) patients had caused a traffic accident after dementia onset. The risk of causing an accident was higher in the FTLD group than in the AD group (odds ratio = 10.4, 95% confidence interval = 3.7-29.1). In addition, the mean duration between dementia onset and a traffic accident was 1.35 years in the FTLD group compared with 3.0 years in the AD group (P < 0.01)., Conclusions: Patients with FTLD were more likely to show dangerous driving behaviours than those with AD, and the risk of causing a traffic accident may be higher in patients with FTLD from an early disease stage., (© 2015 The Authors.

As a result of the growing proportion of drivers aged 65 years and older, it is estimated that the number of elderly drivers with dementia is increasing in Japan. Since June 2002, if a driver is found to be "demented", his/her driving license shall be revoked in Japan. However, there are no consensus guidelines for demented drivers. Between September 1995 and September 2001, we evaluated 30 drivers with dementia (19 males and 11 females, mean age of 69.4 years) in out patients clinic of the Kochi Medical School Hospital and related hospitals. Clinical Diagnosis was Alzheimer's disease in 20, vascular dementia in 3, mixed type dementia in 2, frontotemporal lobar degeneration in 4, other type dementia in 1. We analyzed their driving behavior and family's attitude. Seventy-three point three percent of 30 drivers with dementia continued to drive after diagnosis. In follow-up periods, number of drivers continuing driving was decreased to 13 (43.3%), while six drivers (27.3%) had a traffic accident or violation. Our study suggests that several important medical and social factors should be considered for the management of drivers with dementia. A consensus medical guideline for demented drivers has to be established.
