Alzheimers disease (AD) is the most common dementia in elderly people. The pathological hallmark of AD is amyloid plaques and neurofibrillary tangles, which are made up of Aβ42 and p-tau, respectively. Decreased levels of Aβ42 and increased levels of total tau protein (T-tau) and p-tau in CSF are useful and valid tool for the diagnosis and prognosis of AD. In this study, we investigated the correlation between AD CSF biomarkers and grey matter volume and brain microstructural changes using VBM analysis and DTI measurement.
