Reaction Time in Vascular (Multiinfarct) Dementia
Reaction time (RT) is a physiological measurement which has been found to increase with age and cerebral disease (Benton 1977). For the increase in RT in cerebral disease (Klensch 1973), the particular localisation of the lesion (Benton and Joynt, 1958; Howes and Boller 1975) as well as dementing processes have been considered to be responsible (Miller 1974; Pirozzolo et al., 1981). However, it still remains unknown whether the RT is related to diffuse or focal brain disease or is caused by the loss of mental capabilities. To clarify the situation it seems therefore of interest to investigate patients with cerebrovascular disease (CVD) in whom all relevant parameters, focal lesions in the non-dominant and dominant hemispheres as well as dementing processes could be studied.
