Summary:
The locus coeruleus is the major source of noradrenaline to the brain and contributes to a wide range of physiological and cognitive functions. Neurodegeneration and pathological aggregation of tau protein in the locus coeruleus are early features of progressive supranuclear palsy (PSP). It is proposed to contribute to the clinical expression of the disease, including the PSP Richardson’s syndrome. Researchers investigated whether the tau and neuronal loss are associated with clinical heterogeneity and severity in PSP.
