Evaluating the locus coeruleus as early marker of Alzheimer's disease
Alzheimer’s disease is characterized by a long asymptomatic stage during which the two pathologic hallmarks, beta-amyloid and tau depositions, accumulate, leading to neurodegeneration and the manifestation of clinical symptoms. Being able to effectively delay disease progression will require early intervention, before irreversible damage has occurred. The critical barrier that needs to be resolved to obtain more success in preventive interventions is to find a biomarker that does not measure end-stage pathology, but precedes Aβ and early tau pathology and can predict who is expected to show an increase in Alzheimer’s disease pathology and a decrease in cognition over the following years. Autopsy data reported deposition of hyperphosphorylated tau pathology in the locus coeruleus early in adulthood and before cortical involvement. This indicates that the locus coeruleus may be a promising marker of risk of Alzheimer’s disease. During this talk, I will provide evidence from structural and functional in vivo imaging of the locus coeruleus supporting locus coeruleus imaging as potential marker and discuss the remaining knowledge gaps.
