ADNI: Alzheimer's Disease Neuroimaging Initiative
Study Overview |
Current Status: |
No longer recruiting |
Purpose: |
The purpose of this study is to examine how brain imaging technology can be used with other tests to measure the progression of mild cognitive impairment (MCI) and early Alzheimer’s disease (AD). This information will aid future clinical trials by providing a standard assessment tool to measure the effects of treatments being studied. |

Inclusion Criteria:
Participants will be classified as either MCI patients, AD patients, or normal controls. General Inclusion Criteria will apply to all groups, with specific criteria for each group as described below:
General (applies to each category):
- Between 55 and 90 years of age (Currently, ADNI sites are only recruiting volunteers age 70-90 among people with no memory problems)
- Study partner or caregiver to accompany patient to all scheduled visits
- Fluent in English or Spanish
- Permitted medications stable for at least 4 weeks prior to screening
- Adequate visual and auditory acuity to allow neuropsychological testing
- Good general health with no additional diseases expected to interfere with the study
- Women must be two years post-menopausal or surgically sterile
- Willing and able to complete all baseline assessments, and to participate in the 2-3 year protocol
- Willing to undergo neuroimaging and provide DNA and plasma samples as specified
- Completed 6 grades of education or sufficient work history to exclude mental retardation
- Modified Hachinski score <=4
- Geriatric Depression Scale <6
Specific Criteria for MCI and AD patients:
- Memory complaint by patient or study partner
- Abnormal memory function score on Wechsler Memory Scale (adjusted for education)
- Mini-Mental State Exam score between 24 and 30 (MCI) or 20 and 26 (AD)
- Clinical Dementia Rating = 0.5; Memory Box score at least 0.5 (MCI) or 1.0 (AD)
Exclusion Criteria:
- Any significant neurologic disease other than Alzheimer's disease
- Abnormal baseline MRI
- Presence of pacemakers, aneurysm clips, artificial heart valves, ear implants, metal fragments or foreign objects in the eyes, skin, or body
- Major depression, bipolar disorder, history of schizophrenia
- History of alcohol or substance abuse or dependency within the past 2 years
- Any significant systemic illness or unstable medical condition which could lead to difficulty complying with the protocol
- Clinically significant laboratory abnormalities
- Residence in skilled nursing facility
- Participation in clinical studies involving neuropsychological measures being collected more than one time per year
Specific Exclusion Criteria for MCI and AD:
- Psychotic features, agitation or behavioral problems within the last 3 months which could lead to difficulty complying with the protocol.

Study Description
N/A, Natural History, Longitudinal, Prospective Study
This study will test whether serial magnetic resonance imaging (MRI), positron emission tomography (PET), other biological markers, and clinical and neuropsychological assessment can be combined to measure the progression of mild cognitive impairment (MCI) and early Alzheimer’s disease (AD). The information obtained by studying changes in the brain images of MCI and AD patients and healthy individuals, as well as other assessment tools, will be used to determine the best methods for measuring treatment effects in patients with MCI and AD.
Approximately 800 participants, ranging in age from 55 to 90, will be recruited for the study: 400 patients with MCI, 200 with early AD, and 200 normal controls. Patients with MCI and normal controls will be followed for 3 years, and those with AD will be followed for 2 years. At 6-month intervals all participants will be seen in person or contacted by telephone. All participants will undergo repeated scanning and blood and urine biomarkers will be collected at the time of each scan. All patients will be asked if they are willing to undergo lumbar puncture at baseline and year one, with the goal of a minimum of 20% and as many as 50% of each group providing CSF samples for analysis and storage for future analyses.
NOTE: Beginning in Spring 2007 a subset of the ADNI participants will be offered the opportunity to participate in a supplemental study. The PIB (Pittsburgh Compound B) study provides imaging of amyloid plaque burden. PIB PET scans will be conducted in 24 control, 48 MCI, and 24 AD participants at approximately 16 ADNI PET sites. For entering participants with no previous PET FDG scans, controls and MCI participants will be scanned with PIB at entry (baseline), 12, 24, and 36 months, and AD participants will be scanned with PIB at entry (baseline), 12, and 24 months. For participants who have undergone previous (baseline and 6 month) PET FDG scans, controls and MCI participants will be scanned with PIB at 12, 24, and 36 months, and AD participants will be scanned with PIB at 12 and 24 months.

Precautions:
PET - The primary risk related to PET is that of radiation exposure. The radiation exposure for the study has been limited to a maximum of 35mCi (or 7 PET studies) per patient, which will keep the dosage well below acceptable limits. There is also minor risk associated with venipuncture and radioisotope injection (pain and bruising or painful infiltration of a failed injection).
MRI - There are no proven biologic risks associated with MRI scanning (all patients will be screened for medical contraindications as described in Exclusion Criteria). There is a slight risk of anxiety due to claustrophobia and noise.
Lumbar Puncture - This procedure may cause pain, usually temporary and confined to the lower back. Headache may occur in about 5% of elderly people. In about 1-4% a persistent low-pressure headache may develop (lower rates of post-LP headache have been noted in elderly patients, and when atraumatic--Sprotte--needles are used). If a post-LP headache persists it may need additional treatment. Potential but rare risks include infection, damage to nerves in the back, bleeding into the CSF space, and death (the risk of these is much less than 1%).
Blood Draw - Risks include pain from the needle, bruising or infection at the site of the venipuncture, or fainting as a response to blood draw.
