Several recent studies have provided substantial support for the proposal that a decrease in inhibitory processing may play an important role in cognitive changes occurring in the early stages of Dementia of the Alzheimer Type (DAT). The question addressed by the present study was whether these deficits are the result of the failure of a general inhibitory(More)
A growing number of studies report a deterioration of the executive function (EF) in dementia of the Alzheimer type (DAT). To evaluate EFs in DAT, a new version of the Tower of London (TOL) task, originally developed by Shallice (1982), was adapted. The new version of the test was built up in its easiest possible feature in order to be administrable to(More)
AIMS Our purpose was to identify cognitive tools associated with unsafe driving among elderly drivers of varying cognitive levels. METHODS Twenty drivers with early-stage dementia of the Alzheimer type and 56 nondemented drivers aged 65-85 were recruited. Various cognitive processes were measured and unsafe driving was evaluated during an in-traffic road(More)
BACKGROUND Personal responses to stressful life events are suspected of increasing the risk of serious traffic accidents. METHODS We analyzed data from a French cohort study (the GAZEL cohort), including a retrospective driving behavior questionnaire, from 13,915 participants (10,542 men age 52-62 years and 3373 women age 47-62 years in 2001). Follow-up(More)
STUDY OBJECTIVE The use of connections who have the authority to cancel penalties related to traffic violations seems to be very frequent in France. This study aimed at describing risk taking driving behaviours associated in France with using connections to have traffic tickets cancelled (ticket fixing). DESIGN Retrospective study on driving behaviour and(More)
The type A behavior pattern (TABP), characterized by impatience, time urgency, and hostility, was originally developed in relation to coronary heart disease. Since 1986, there has been a debate on whether the TABP is also associated with risky driving behaviors leading to increased risks in road traffic accidents (RTAs). The authors examined prospectively(More)
OBJECTIVES To identify factors associated with driving restriction in elderly men and women. DESIGN Prospective cohort study of French drivers from 2003 to 2009. SETTING The Three-City Cohort of Bordeaux, a prospective study of 2,104 people aged 65 and older. PARTICIPANTS Five hundred twenty-three drivers with a mean age of 76 (273 male, 250 female).(More)
BACKGROUND AND OBJECTIVE To assess the influence of medical conditions on road traffic accidents among a cohort of middle-aged workers and pensioners. STUDY DESIGN AND SETTING A longitudinal study of 13,548 participants from a cohort study of French workers. Follow-up data covered the 1989-2000 period. Adjusted hazards ratios (HR(adj)) for serious(More)
To investigate the contribution of inhibitory deficits in the deterioration of executive function abilities in Alzheimer's disease (AD), a modified version of the Stroop test was submitted to 44 AD patients and 44 elderly controls. Half of the subjects performed successively the Interference Stroop task, the two control tasks and the Reverse Stroop task,(More)
