Alzheimer's disease (AD) is the common cause of dementia in the elderly. Currently, clinical diagnosis of AD is based on clinical criteria that require the presence of memory impairment and at least one of several other cognitive dysfunctions. Although these criteria have been well accepted, detection of AD patients in early, or at least mild, stage of the disease is still problematic. Previous neuropathological studies have suggested that substantial deposition of diffuse plaques is considered to be the initial pathological change in AD that precedes cognitive deterioration. Thus, molecular positron emission tomography (PET) imaging that can detect diffuse plaques in vivo may be ideal for pre-symptomatic detection of AD patients. The purpose of this multi-center trial is to compare the PET imaging using [11C]BF-227 and [18F]FDG, magnetic resonance imaging (MRI), and psychological cognitive tests among healthy volunteers, mild cognitive impairment, and AD patients.

Male and Female
1)Criteria for Normal volunteers:
Normal Volunteers are examined by FDG-PET, [11C]BF-227-PET, MRI and psychological tests. Male and female volunteers aged more than 35 years old are recruited for this study. They should understand the purpose and rationale of this study.
2)Criteria for Alzheimer disease:
Alzheimer patients diagnosed as a probable AD according to NINCDS-ADRDA are enrolled. MMSE (Mini-mental state examination) is over 18, and apparent cognitive dysfunction is present in the patients. Informed consents are obtained from patients family and possibly from patients themselves.
3)Criteria for Mild Cognitive Impairment
1.Amnestic MCI.
2.No apparent neurological and psychiatric disorders.
3.There are no neurological symptoms.
4.There are no psychiatric symptoms.
5.The patients do not show dementia.
1)The past and present history of alcoholism.
2)The past and present history of epilepsy
3)Education period is less than 6 years.
4)There are no persons who can give any information on patients symptoms.
5)Diabetic patients treated with insulin
6)Patients treated with antidepressants, antipsychotics, and long-term sedative-hypnotics.
7)Severe complication including malignancy, heart failure, hepatic dysfunction, renal dysfunction, endocrine disorders, etc.
8)Other patients and volunteers that investigators and medical doctors need to exclude.

Partially published
Initial PET studies using [11C]BF-227 have been started at Tohoku University and Tokyo Metropolitan Institute of Gerontology. The accumulation patterns of [11C]BF-227 in Alzheimer patients were different from those of normal volunteers. Increased brain areas were consistent with those rich with amyloid plaques. The half of MCI patients showed increased accumulation of [11C]BF227. We also compared PET amyloid imaging to FDG-PET, and the preliminary results suggested the superiority of amyloid imaging.

The repeated measurement of [11C]BF227 would be possible during the study periods. Other PET facilities interested in amyloid imaging would be able to participate in this study.
