6D80.0 Dementia due to Alzheimer disease with early onset

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

Dementia due to Alzheimer disease in which symptoms emerge before the age of 65 years. It is relatively rare, representing less than 5% of all cases, and may be genetically determined (autosomal dominant Alzheimer disease). Clinical presentation may be similar to cases with later onset, but progression of cognitive deficits may be more rapid.

coding note

This category should never be used in primary tabulation. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of dementia in diseases classified elsewhere. When dementia is due to multiple aetiologies, code all that apply.
