Use mild cognitive impairment (MCI), amnestic MCI, and single non-memory domain MCI to frame the working diagnosis and next step; treat it as a safety constraint before prescribing or reassuring. Make amnestic MCI the checkpoint that determines whether you escalate testing, narrow the differential, or change treatment.

Mild cognitive impairment, or MCI, is a state of cognitive decline where an individual experiences noticeable changes in memory or thinking; Specific subtype where memory loss is the standout, primary feature; Memory remains relatively intact, but there is a selective drop in a single, different cognitive area—like language skills, executive functioning, or visuospatial abilities; These changes don't significantly interfere with their daily activities or independent living, meaning the criteria for a full dementia diagnosis aren't met; While other cognitive areas might show minor changes, the memory deficit is prominent, and this particular form frequently serves as a precursor to Alzheimer’s disease
