Outline of Final Research Achievements |
Argyrophilic grain dementia (AGD) is a new type of non-Alzheimer dementia (AD) which is the most common cause in mild cognitive impairment of the elderly. AGD is a pathological entity and there are few clinical studies of AGD. Thirty-four patients were clinically diagnosed as AGD based on the MRI findings of focal atrophy of the anterior medial temporal lobes as well as slowly progressive amnesia. Amyloid PET scans using Pittsburgh Compound B (PiB) were performed and revealed negative in 16 (47%) patients with AGD, while they showed positive in all 14 AD patients. Apolipoprotein E4 was tended to be positive in amyloid positive AGD patients. Patients of amyloid negative without E4 may be the core population of AGD. AGD can be diagnosed clinically and will be important as non-AD dementia in the elderly.
