Amnesia epidemiology and demographics
Introduction
Overview
Overview
Memory impairment tends to increase with age. Forty percent of the population over age sixty have some degree of memory loss. Amnesia and mild cognitive impairment is more prevalent in middle-aged to older Non-Hispanic Black and older Latino as compared to non-Hispanic Whites.
Epidemiology and Demographics
Epidemiology and Demographics
Prevalence
- The prevalence of dissociative amnesia is 1,000 to 2,600 per 100,000 (1.0% to 2.6%) of the overall population.[1]
- Prevalence of Alzheimer’s disease is 20% over the age of 85.[2]
- The prevalence of dissociative fugue is approximately 0.2%. This might be underestimated as dissociative fugue is under diagnosed.[3]
- Worldwide prevalence of Korsakoff Syndrome is 0-2% and 1-2% in the United States. Prevalence is higher in elderly living by themselves, psychiatric inpatients and the homeless.[4]
Incidence
- Worldwide, the incidence of transient global amnesia is approximately 2.9– 10 per 100,000 cases per year. [5]
- Incidence of dissociative disorder is higher in substance abuse cases.[6]
Gender
- Higher prevalence of Alzheimer’s disease is seen in women than men.[7]
- Males are more affected by Korsakoff Syndrome than females.
Race
- Memory loss and mild cognitive impairment is more prevalent in middle-aged to older Non-Hispanic Black and older Latino as compared to non-Hispanic Whites.[8]
