Modern methods for the instrumental detection of cognitive impairment in Alzheimer's and dementia patients

Patients with cognitive impairment diseases are no longer fully oriented to time and space. The disease may be the root cause of all cognitive impairments (CI). Depending on the precise diagnosis, different cognitive disorders require different treatments. The three major goals of neuroimaging in Alzheimer's disease (AD) are to detect very early AD at a prodromal stage of moderate cognitive impairment, to differentiate AD from other dementia-causing illnesses, and to forecast the progression of MCI to AD. Consequently, this study's objective is to examine the most sensitive instrumental testing techniques for the early identification of cognitive deterioration in AD and dementia patients.
