Furthermore, the diagnosis of Mild NCD requires a psychometric performance from -1 standard deviation (SD) relative to a matched normative group whereas MCI requires a comparatively more severe impairment from -1.5SD.

For example, a predominant learning and memory impairment is expected in patients with NCD due to Alzheimer’s Disease (AD), whereas NCD due to cerebrovascular disease is characterized by executive functions and attentional deficits. The profile of cognitive domains affected in NCD can be heterogeneous depending on the disease etiology. While Mild NCD and mild cognitive impairment (MCI) are conceptually similar, Mild NCD encompasses individuals with a milder, possibly earlier stage of cognitive decline compared to MCI. Mild NCD refers to a syndrome of cognitive decline that is of modest severity with minimal impact on daily functions. Mild Neurocognitive Disorder (NCD) is a newly added diagnostic entity recently published in the Diagnostic and Statistical Manual of Mental Disorders, 5 th Edition (DSM-5).
