Higher brain functions (HBF) required for automobile driving can be broadly classified into “attention ( information processing speed, reaction time, etc.) ,” “visuospatial function,” “language,” “executive function,” and “memory.” Many reports suggest that the Trail Making Test (TMT), Symbol Digit Modalities Test (SDMT), Digit Symbol of the Wechsler Adult Intelligence Scale (WAIS), Rey-Osterrieth Complex figure (ROCF), reaction time test, and Stroke Drivers Screening Assessment (SDSA) , etc. are important for understanding the degree of HBF. “Indication and judgment of neuropsychological examination associated with automobile driving when higher brain dysfunction is suspected due to stroke or traumatic brain injury, etc.” was published by the Japan Society for Higher Brain Dysfunction. The flowcharts were divided according to the presence or absence of aphasia, and the evaluation was performed in the following order : (1) dementia, (2) unilateral spatial neglect, (3) attention and processing speed, (4) composition ability, (5) executive function, and (6) apraxia（in patients with aphasia）. In particular, the evaluation of (3) emphasizes the Japanese version of the TMT (TMT-J). It is undesirable to judge only the values of the results. It is necessary to understand the whole picture of the patient from the medical history, brain imaging, information of daily life, social life, etc., and judge it comprehensively.
