The Impact of Vascular Risk Factors on Cerebral Amyloid Angiopathy: A Cohort Study in Hereditary Cerebral Amyloid Angiopathy and a Systemic Review in Sporadic Cerebral Amyloid Angiopathy.

Introduction: Cerebral amyloid angiopathy (CAA) has a remarkably variable disease course, even in monogenetic hereditary forms. Our aim was to investigate the prevalence of vascular risk factors and their effect on disease onset and course in Dutch-type hereditary (D-)CAA and sporadic CAA.

Methods: We performed a cohort study in D-CAA to investigate the association between vascular risk factors (hypertension, hypercholesterolemia, smoking, and alcohol use) and age of intracerebral hemorrhage (ICH) onset and time of ICH recurrence with survival analyses.

Neuropsychiatric symptoms with focus on apathy and irritability in sporadic and hereditary cerebral amyloid angiopathy.

Background: Neuropsychiatric symptoms (NPS) may affect cognition, but their burden in cerebral amyloid angiopathy (CAA), one of the main causes of intracerebral hemorrhage (ICH) and dementia in the elderly, remains unclear. We investigated NPS, with emphasis on apathy and irritability in sporadic (sCAA) and Dutch-type hereditary (D-)CAA.

Methods: We included patients with sCAA and (pre)symptomatic D-CAA, and controls from four prospective cohort studies.
