How Early is Early Alzheimer’s Disease?
02:00pm to 04:00pm

In the last years, the concept that any disease-modifying treatment for neurodegenerative disorders should be started before irreversible neuronal damage occurs became widely accepted. As a consequence, it is increasingly important to make the diagnosis as early in the disease process as possible, often in rather young cases. The presence of cerebral amyloid pathology, the marker of Alzheimer’s disease, as determined by positron emission tomography or cerebrospinal fluid abnormalities, is found in healthy people from the fifties on. Cerebral amyloid pathology is associated with APOE genotype and cognitive impairment. It seems a there is long 20- to 30-year interval between the first development of amyloid positivity and the onset of dementia, suggesting a promising time window opportunity for prevention.


The seminar is free, and all are welcome (including members of the public) without needing to book a place.
