The cholesterol is produced in the astrocytes and shipped to neurons where it activates amyloid production through a process called substrate presentation. The process required apoE. Cholesterol's regulation of Tau production is less well understood, but knocking out the cholesterol synthesis enzyme SREBP2 decreased Tau phosphorylation.
The direct relationship between cholesterol and dementia is still unclear, though elevated levels of specifically LDL cholesterol are considered a risk factor for dementia, says Peter Gliebus, M.D ...
More than one type of dementia, known as mixed dementia, may exist together in about 10% of dementia cases. [2] The most common type of mixed dementia is Alzheimer's disease and vascular dementia.
