BACKGROUND: Disease-specific biomarkers should reflect a fundamental feature of neuropathology and be validated in neuropathologically confirmed cases. Several synaptic proteins have been described in cerebrospinal fluid (CSF) of patients with dementia. In Lewy body disease alpha-synuclein is incorporated within Lewy bodies and alpha-, beta- and gamma-synucleins in dystrophic neuritis. These pathological changes are expected to be seen in CSF. METHODS: A total of 25 CSF post-mortem samples (8 control and 17 subjects with dementia) were used to quantify alpha- and gamma-synucleins and IgG. RESULTS: We describe for the first time the presence of gamma-synuclein in CSF. There is an elevation of both alpha- and gamma-synucleins in CSF from elderly individuals with Alzheimer's disease, Lewy body disease (LBD) and vascular dementia (CVD), compared to normal controls. gamma-Synuclein showed a greater elevation in LBD, IgG in CVD. The elevation of alpha- and gamma-synucleins was seen from Braak stage III onwards and remained stable until Braak stage VI. These results were not influenced by age at death or post-mortem delay. CONCLUSIONS: The reported increases in alpha- and gamma-synucleins and IgG in the ventricular CSF of individuals with dementia are novel findings. They now need to be explored further using a greater number of cases in each subgroup, using lumbar CSF samples to determine their applicability and relevance to a clinical diagnostic setting. It needs to be established whether using these markers may help to discriminate LBD from other types of neurodegenerative and vascular dementias.
