Brief Summary:

Cerebral amyloid angiopathy (CAA) is one of the major types of cerebral small vessel disease, and a leading cause of spontaneous intracerebral hemorrhage and cognitive decline in elderly patients. Although increasingly detected, a number of aspects including the pathophysiology, the clinical and neuroradiological phenotype and the disease course are still under investigation. The incomplete knowledge of the disease limits the implementation of evidence based guidelines on patient's clinical management and the development of treatments able to prevent or reduce disease progression.

The SENECA (SEarchiNg biomarkErs of Cerebral Angiopathy) project is the first Italian multicentre cohort study aimed at better defining the disease natural history and identifying clinical and neuroradiological markers of disease progression. By a multidisciplinary approach and the collection of a large and well phenotyped series and biorepository of CAA patients, the study is ultimately expected to improve the diagnosis and the knowledge of CAA pathophysiological mechanisms.

Condition or disease Intervention/treatment
Cerebral Amyloid Angiopathy Other: CAA patients data collection

Detailed Description:
The SENECA is an Italian multicenter network integrating the experience of neurologists, neuroradiologists, neuro-ophthalmologists and biologists and allowing the standardized collection of a well-characterized wide series of sporadic and familial CAA patients.

Official Title: SEarchiNg biomarkErs Cerebral Amyloid Angiopathy (SENECA): Italian Network for the Study of CAA
Estimated Study Start Date : May 1, 2020
Estimated Primary Completion Date : December 31, 2022
Estimated Study Completion Date : December 31, 2024

Group/Cohort Intervention/treatment
Cerebral amyloid angiopathy (CAA)
Cerebral amyloid angiopathy (CAA) patients
Other: CAA patients data collection
Demographic and clinical data of each patient, including index event that led to the diagnosis (cerebrovascular disease, dementia, gait disturbance, TFNE, seizures, headache), vascular risk factors, history of brain injury or neurosurgery, familial history, and pharmacological treatment will be collected by neurologists in charge.
Other Name: Prognostic factors evaluation

Primary Outcome Measures :
  1. Clinical and neuroradiological phenotype [ Time Frame: 24 months ]
    description of the phenotypic characteristics of a large population of CAA patients collected in Italy

Secondary Outcome Measures :
  1. severity of the neuroradiological picture [ Time Frame: 24 months ]
    Evaluation of the severity of the neuroradiological picture (presence and site of WMHs, CMBs, cSS, CMIs, EPVS ,global cortical atrophy and SAH)

Biospecimen Retention:   Samples With DNA
A peripheral blood withdrawal for APOE allele screening will be performed in all patients, after informed consent obtainment. Additionally, cases with early onset clinical manifestations and/or rapid clinical progression and/or relatives with a diagnosis of CAA or presenting early onset CAA clinical features will be addressed to the genetic screening of Amyloid Precursor Protein (APP) and Transthyretin (TTR) gene. A subgroup of patients will undergo at T0, T1 and T2 a whole venous blood withdrawal, to collect serum and plasma samples, evaluate the platelet concentration of Aβ40 by thioflavin T (ThT) assay and Western blot analysis and the inflammatory and endothelial profile of CAA patients by ELISA or Bio-Plex Panels
