Summary

This study looks at how cholesterol and its byproducts relate to different types of dementia, including Alzheimer's and frontotemporal dementia. Researchers will measure these substances in brain tissue, spinal fluid, and blood from 80 adults aged 40-85. The goal is to find patterns that could help diagnose or track dementia progression, not to test a treatment.

Who is studied

We will use samples (CSF and plasma) already collected from patients from Unit 1 over years. We will include 40 AD, 40 FTD and 20 age-matched non demented controls. Clinical and MRI data will be retrospectively collected as well as the levels of markers of neurodegeneration (tau, Abeta42 and phospho-tau) on CSF. Longitudinal study We will recruit 30 AD patients, 20 FTD patients and 10 patients with primary tauopathies (PSP/CBD) from out and inpatients of Neurology 5-Neuropathology Unit. A group of 20 age-matched subjects without neurological and/or psychiatric diseases will be enrolled as controls. The duration of enrolment will be 18 months.
