In a new study, supported by Swedish Brain Power, researchers compared measurements with PET scanner of the brain with measurement of beta-amyloid in the spinal fluid to see how they match. The results suggest that it is not completely identical forms of beta amyloid found in the brain and spinal fluid.
– This may justify that in some unclear cases, the diagnosis should perform amyloid PET scan to complement the cerebrospinal fluid sample. The findings are also important because it is increasingly common to include amyloid-PET studies of patients in new drug studies, says the study’s coordinator Brain Power researcher Agneta Nordberg, professor in the Department of Neurobiology, Care Sciences and Society, Center for Alzheimer’s Research, Karolinska Institutet.
Doctoral student Antoine Leuzy at the same institution is the study’s first author.
