Abstract
|
|
|
|
We report herein a 78-year-old woman with insidiously progressive cognitive impairment and asymmetric amyloid deposition and neurodegeneration. Brain magnetic resonance imaging revealed remarkable atrophy in the right-sided temporal lobe and hippocampus. Early dynamic 18F-flutemetamol brain amyloid positron-emission tomography images showed decreased uptake in the right temporoparietal regions. Delayed images revealed amyloid deposition which was most remarkable in the right frontotemporoparietal regions. Asymmetries of amyloid burden and neuronal dysfunction are positively correlated in Alzheimer’s disease in cortical regions with high amyloid load.
