The Religious Orders Study
• > 1,100 older nuns, priests, and brothers without known dementia from across the U.S.
• All agreed to annual cognitive and motor testing• All agreed to brain donation at the time of death• > 95% follow-up of survivors• > 210 persons have developed incident AD• > 90% autopsy rate with > 375 brain autopsies

The Rush Memory and Aging Project … because memories should last a lifetime
• ~ 1,200 residents from about 40 retirement communities and senior housing from across the Chicago area
• All agreed to annual cognitive and motor testing, and blood draw.
• All agreed to donate brain, spinal cord, muscle, and nerve at the time of death
• > 95% follow-up of survivors• > 135 persons have developed incident AD• > 80% autopsy rate with > 180 autopsies to date

AD puzzle (paradigm) over past two decades:
Derivative of these criteria: Clinical (Probable) AD – progressive dementia with memory loss Pathologic AD – density of plaques and tangles “Definite AD” – clinical phenotype and AD pathology

Neurobiol Aging. 1997;18(4 Suppl):S1-2.
“Any Alzheimer’s disease changes in the postmortem brain (i.e., diffuse amyloid or neuritic plaques, neurofibrillary tangles)… are considered to be pathological even in instances where they appear to be incidental.”
![Page 38: Cerebrovascular Disease and the Relation of Alzheimer's ... · Cerebrovascular Disease and the Relation of Alzheimer's Disease Pathology to Cognition David A.

RecommendationAbolish current clinical-pathologic definition of diseaseDefine AD neuropathologically“AD” may:
be clinically silentcause structural changes on neuroimagingcause MCI or dementiacause other clinical manifestations, even in the absence of cognitive
impairmentparkinsonian signsloss of body mass indexloss of odor identificationneuropsychiatric features, e.g., depression?
Public Health burden of “AD” is much larger than currently recognized

Stage I – asymptomatic “widespread” amyloid deposition with or without tangles
Stage II – asymptomatic amyloid deposition with tangles and “significant” structural changes on MRI
Stage III – mild cognitive or motor impairment, or neuropsychiatric features
Stage IV – dementia, usually with motor impairment and neuropsychiatric features

Imagine there’s no Alzheimer’s It's easy if you try
No plaques or tangles Old neurons do not die Imagine all old people Making new memories
Imagine there’s no VaD It isn't hard to do
No strokes or infarcts No WML’s, too
Imagine all old people Planning life ahead
Imagine there’s no LBD I wonder if you can No protein deposits
No α-synuclein Imagine all old people Standing, walking tall
You may say I'm a dreamer But I'm not the only one
I hope someday you'll join usAnd the fight against dementia will be won

No α-synuclein Imagine all old people Standing, walking tall
You may say I'm a dreamer But I'm not the only one
I hope someday you'll join usAnd the fight against dementia will be won

Imagine there’s no Alzheimer’s It's easy if you try
No plaques or tangles Old neurons do not die Imagine all old people Making new memories
Imagine there’s no VaD It isn't hard to do
No strokes or infarcts No WML’s, too
Imagine all old people Planning life ahead
Imagine there’s no LBD I wonder if you can No protein deposits
No α-synuclein Imagine all old people Standing, walking tall
You may say I'm a dreamer But I'm not the only one
I hope someday you'll join usAnd the fight against dementia will be won
