Persons aged 65 years and over diagnosed with Alzheimer’s disease or other types of dementia, persons receiving treatment for Alzheimer’s disease or other types of dementia (ICD-9-CM codes 331.0, 331.1, 331.11, 331.19, 331.2, 331.7, 290.10, 290.11, 290.12, 290.13, 290.20, 290.21, 290.3, 290.40, 290.41, 290.42, 290.43, 294.0, 294.1, 294.10, 294.11, 294.8, 797 in any field on the claim)
From the 2007 Medicare Current Beneficiary Survey:
Has a doctor ever told you that you (the person) had Alzheimer's disease?
Has a doctor ever told you that you (the person) had any type of dementia other than Alzheimer's disease?
Awareness of dementia was defined as an affirmative response by the respondent or their proxy to either of the questions shown in the Questions section.
Adults aged 65 years and older were defined as having Alzheimer’s disease or another dementia if they have at least one Medicare claim with a diagnostic code for Alzheimer's disease or another dementia (as specified in the Numerator and Denominator). Only beneficiaries with claims data that occurred before the Medicare Care Beneficiary Survey (MCBS) survey date were included.
