Three of the sufferers had gentle cognitive impairment, and one had frontotemporal dementia, the case report authors wrote. They famous that their case report is exclusive in that it is the first report of DVRC that analyzed mind exercise with scans, evaluated the affected person’s CSF and included repeated neuropsychological testing.
