General inclusion/exclusion criteria are as follows:

- LMCI subjects: MMSE scores between 24-30(inclusive), a memory complaint, have objective memory loss measured by education adjusted scores on Wechsler Memory Scale Logical Memory III story A delayed recall scores (education ≥16 years: ≤8; 6-15 years: ≤4), a CDR of 0.5 with a mandatory requirement of the memory box score being 0.5 or greater, essentially preserved activities of daily living, and an absence of dementia.
- Mild AD: MMSE scores between 20-26 (inclusive), CDR of 0.5 or 1.0, and meets NINCDS/ADRDA criteria for probable AD, have objective memory loss measured by education adjusted scores on Wechsler Memory Scale Logical Memory III story A delayed recall scores (education ≥16 years: ≤8; 6-15 years: ≤4)
Who cannot join
- Subjects taking antidepressant medications with anticholinergic properties will be excluded, and the regular use of narcotic agents have to be limited to < 2 doses per week within 4 weeks of screening. Neuroleptic medications and other drugs with anticholinergic properties, anti-parkinsonian medications are not allowed within 4 weeks of screening. Diuretic drugs should not be started or need to be discontinued 4 weeks prior to screening. Cholinesterase inhibitors and memantine are permitted if the doses are stable for 4 weeks prior to screening for subjects with MCI and AD. Estrogen and estrogen-like compounds and vitamin E are allowed if the dose have been stable for 4 weeks prior to screening. Participants are required to report any medication changes to the site investigators once they are enrolled in the study.

About this study
Alzheimer's disease (AD) may be one of the most pressing problems facing all countries around the world as the population ages.AD is a slowly evolving process that likes begins years to decades before the clinical symptoms area manifest. However, as one would like to identify the disease process at an earlier point in the clinical continuum, the precision of the diagnosis is reduced. Therefore, the challenge is to try to identify the process at the pre-dementia stage and enhance the specificity of the clinical diagnosis through the use of imaging and other biomarkers. Mild cognitive impairment (MCI) represents an attempt to characterize subjects at an early clinical phase of AD and subjects with MCI have been a target for prevention trials. There are two pathological landmarks, in terms of extra-cellular senile plaques and intracellular neurofibrillary tangles. Although present symptomatic treatments provide some benefit to patients with AD, they are not the solution for AD. Up to date, there are still no therapies can alter the underlying nature of the AD process. Therefore, the earlier the intervention takes place, presumably, the greater the protection against further neuronal damage will be appreciated.The Alzheimer's Disease Neuroimaging Initiate (ADNI) is a consortium of universities and medical centers in the United States and Canada established to develop standardized imaging techniques and biomarkers procedures in normal subjects, subjects with MCI and subjects with mild AD. ADNI has been a groundbreaking project, establishing pre-competitive collaboration and real-time data sharing among academia and industry investigators to clarify the relationships among demographic, genetic, clinical, cognitive, neuroimaging and biochemical measures throughout the course of AD neurobiology, in order to facilitate the development of effective therapeutics.This project has exceeded expectations, providing insights into disease mechanisms as well as hugely valuable advances, based primarily on the use of standardized biomarkers, to drug development programs. A number of the leading disease-modifying drug development programs are now employing ADNI methodology toward more efficient trial design, particularly in the critically important early (pre-dementia) AD population

Questions about this trial
What is this clinical trial studying?
A study testing F18-AV45 in people with Alzheimer's Disease, run by Chang Gung Memorial Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 20 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Tzu-Chen YEN, MD,PhD (03-3281200 ext. 2744, yen1110@adm.cgmh.org.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Rate of conversion from NC, EMCI, LMCI to AD. (time frame: three years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jun 2012.
