ObjectiveTo study the changes of biomarkers in cerebrospinal fluid (CSF) in cerebral amyloid angiopathy (CAA) dementia and Alzheimer's disease.MethodsLevels of amyloid protein β (Aβ42, Aβ40) and phosphorylated Tau-protein (P-tau) in CSF and ratio of Aβ42/Aβ40 were tested in 5 cases with CAA dementia and 20 cases with Alzheimer's disease collected at Peking Union Medical College Hospital from December 2001 to March 2011.ResultsThe levels of Aβ42, Aβ40, and P-tau in CSF and ratio of Aβ42/Aβ40 were (660.4±265.2) ng/L, (7111.0±1033.4) ng/L, (71.8±51.5) ng/L, and 0.077±0.033, respectively in CAA dementia and (663.6±365.6) ng/L, (5115.0±2931.1) ng/L, (47.7±38.8) ng/L, and 0.192±0.140, respectively in Alzheimer's disease patients. There were no statistically significant differences between CAA dementia and Alzheimer's disease in terms of these CSF biomarkers (all P>0.05).ConclusionMeasurements of CSF biomarkers may not be helpful in differential diagnosis of CAA and Alzheimer's disease.
