Alzheimer Disease - Dementia |
| Purpose: |
|
The goal of this project is to develop an early diagnostic test for Alzheimer's disease (AD)
by monitoring loss of neurons and brain size reductions over a period of five years.
|
| Study Summary: |
|
Studies of normal aging and mild cognitive impairment (MCI) show that loss of neurons and
reduction in size of the hippocampal part of the brain predict a person's conversion from
MCI to Alzheimer's disease (AD). Increases in tangle-related abnormal tau proteins,
specifically P-tau231, also appear to be related.
This study will collect neuropsychological data, magnetic resonance imaging (MRI), and
cerebrospinal fluid (CSF) from volunteer participants to measure the relationship between
changes in brain volume, CSF levels, and memory performance.
From the data researchers hope to develop an early diagnostic test for AD.
The study will include 170 participants between the ages of 60 and 80 years, some normal,
some with MCI, some with mild AD, and some with frontotemporal dementia. After initial
screening of volunteers, the researchers will give participants a complete baseline exam and
24-month follow-up exams over a period of five years.

| Criteria: |
|
Inclusion Criteria:
- Males and females, from all racial and ethnic categories between the ages of 60-80
years of age, with English as their first language.
- Residents of the New York City metropolitan area.
- Minimum of 12 years of education.
- Participants will be grouped according to the following classifications: normal
aging, mild cognitive impairment (MCI), Alzheimer's disease (AD), or frontotemporal
dementia (FTD).
- Participants will agree to ApoE genotyping and DNA banking.
Exclusion Criteria:
- Past history or MRI evidence of brain damage including significant trauma, stroke,
hydrocephalus, lacunar infarcts, seizures, mental retardation or serious neurological
disorder.
- Significant history of alcoholism or drug abuse.
- History of psychiatric illness (e.g., schizophrenia, mania or depression).
- Any focal signs or significant neuropathology.
- A score of 4 or greater on the Modified Hachinski Ischemia Scale suggesting
cerebrovascular disease.
- A total score of 16 or more on the Hamilton Depression Scale to exclude possible
cases of primary depression.
- Evidence of clinically relevant and uncontrolled hypertensive, cardiac, pulmonary,
vascular, metabolic or hematologic conditions.
- Physical impairment of such severity as to adversely affect the validity of
psychological testing.
- Hostility or refusal to cooperate.
- Any prosthetic devices (e.g., pacemaker or surgical clips) that could be affected by
the magnetic field employed during MRI imaging.
- History of familial early onset dementia.
