PET with amyloid ligands should not be applied routinely in early diagnostics of Alzheimer's disease

Abstract

Recent diagnostic criteria for Alzheimer's disease incorporate biomarkers in order to increase the diagnostic accuracy. In a recent Cochrane review the ligand (11)C-PiB showed a high sensitivity, but low specificity for detecting patients with mild cognitive impairment who would develop Alzheimer's dementia. Given the evolution of Alzheimer pathology, these findings are not surprising. With current limited treatment options for MCI, (11)C-PiB-PET cannot be recommended for routine use in MCI and should be used only in selected cases where a positive scan will alter management.

Alzheimer's Disease: Amyloid Beta

Alzheimer's disease is a neurodegenerative disease associated with the accumulation of amyloid plaques in the brain; these plaques are comprised of amyloid beta deposits. Here is the latest research in this field.

Alzheimer's Disease: APP

Amyloid precursor protein (APP) proteolysis is critical for the development of Alzheimer's disease, a neurodegenerative disease associated with accumulation of amyloid plaques in the brain. Here is the latest research on APP and Alzheimer's disease.

Alzheimer's Disease: Neuroimaging

Neuroimaging can help identify pathological hallmarks of Alzheimer's disease (AD). Here is the latest research on neuroimaging modalities, including magnetic resonance imaging and positron emission tomography, in AD.

Alzheimer's Disease: Early Markers

Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive cognitive and behavioral decline. Targeting markers in the earliest stages of the disease may mitigate the progression of AD. This feed focuses on early diagnosis and markers, as well as environmental, pharmacological, and drug-response biomarkers associated with this disease.
