Serum anti-amyloid-beta antibodies and Alzheimer's disease in elderly Korean patients

초록

Alzheimer's disease (AD) is characterized by the deposition of senile plaques and neurofibrillary tangles in the brain. The presence of the amyloid-beta (A beta) peptide in senile plaques seems to play a central role in the neuropathology of AD. Diagnosis of AD involves neuropsychological examinations or magnetic resonance imaging and, to date, a specific diagnostic marker indicating AD has not been found. This study analysed anti-A beta antibodies from the serum of 153 patients with AD using an enzyme-linked immunosorbent assay method. The levels of anti-A beta antibody from patients in the control group (n = 193) were compared with those of patients with AD. Our results showed a significantly lower anti-A beta antibody level in patients with AD than in the control group. These results showed that the anti-A beta antibody level in serum could potentially be used to diagnose the presence of AD.
