Episode notes
MCI Is A Distinct Clinical Syndrome
- Mild cognitive impairment (MCI) is a syndrome between normal aging and dementia, not a single diagnosis.
- MCI often features memory complaints while daily function remains largely preserved.
Normal Aging Versus Pathologic Change
- Aging commonly causes slowed processing, reduced multitasking, and short-term memory lapses.
- Distinguish typical age changes from patterns of decline that suggest MCI by tracking frequency and severity.
MCI Prevalence And Progression Rates
- MCI prevalence in older adults is roughly 10–16% and progression to dementia runs about 8–15% per year.
- Clinical populations progress faster than random community samples, so context matters.
