ReviewCSF biomarkers in neurodegenerative and vascular dementias.
Neurodegenerative diseases with abnormal protein aggregates such as Alzheimer's disease, tauopathies, synucleinopathies, and prionopathies, together with vascular encephalopathies, are cause of cognitive impairment and dementia. Identification of reliable biomarkers in biological fluids, particularly in the cerebrospinal fluid (CSF), is of extreme importance in optimizing the precise early clinical diagnosis of distinct entities and predicting the outcome in particular settings. ⋯ Correlation of CSF markers and underlying pathological molecular substrates in brain is an exciting field for further study. However, while some dementias such as Creutzfeldt-Jakob disease have accurate CSF biomarkers, other disease types such as dementia with Lewy bodies, vascular dementia, and frontotemporal dementia lack reliable biomarkers for their specific clinical diagnosis.
