Neurodegenerative disorders (NDDs), such as Parkinson¿s disease (PD), Alzheimer¿s disease (AD), Frontotemporal dementia (FTD) and Amyotrophic Lateral Sclerosis (ALS) are characterized by aggregation and intracellular accumulation of misfolded proteins, which are believed to play a key role in synaptic dysfunction and neuronal death. Protein structural complexes in biofluids have been proposed to mirror pathological conditions suggesting their use as biomarkers for NDDs characterized by protein aggregation. In this framework, we plan to: i) collect a large cohort of NDD and prodromal patients and healthy subjects using standardized clinical and genetics procedures; ii) apply a novel method based on genomics, proteomics and bioinformatic analysis to map protein complexes in biofluids; iii) identify novel circulating biomarkers and correlate them to genetic profiling and disease endophenotypes, and; iv) validate the biological properties in human brain tissue and dopaminergic cultures.
Inclusion criteria for PD patients.
Inclusion criteria forAD patients. Patients will be selected at the Center for Cognitive Disorders and Dementias (CDCD) SCDU Neurology, AOU Maggiore della Carità, Novara. Patients with AD will be included after diagnosis of probable Alzheimer's disease according to the McKhann criteria (2011) and supported by positive biomarkers for amyloidopathy (PET with amyloid tracer or amyloid cerebrospinal fluid dosage).
Inclusion criteria for FTD/ALS patients. For UPO, patients will be selected at the tertiary center Amyotrophic Lateral Sclerosis - SCDU Neurology, AOU Maggiore della Carità, Novara. Patients with amyotrophic lateral sclerosis will be included following a diagnosis according to the El Escorial criteria - revised (2015): in this regard, only patients with a definite or probable diagnosis supported by laboratory will be included. For patients with FTD, they will be selected at both centers mentioned above with a diagnosis according to the Rascovsky criteria (2011). In this group, the diagnosis will be supported by negative biomarkers for amyloidopathy (PET with amyloid tracer or amyloid cerebrospinal fluid dosage). For patients with concomitant ALS and FTD, the El Escorial criteria (2015) associated with the Strong criteria (2017) will be used.
