Cystatin C, a protein inhibitor of lysosomal cysteine proteinases, was demonstrated by immunohistochemical techniques to be present in the birefringent amyloid deposits of the small arteries in the cerebrum, cerebellum, and leptomeninges of 10 Icelandic individuals with hereditary cerebral

Accumulation of amyloid-β protein (Aβ) in the brain is thought to be a causal event in Alzheimer's disease (AD). Immunotherapy targeting Aβ holds great promise for reducing Aβ in the brain. Here, we evaluated the efficacy and safety of anti-Aβ single-chain antibody (scFv59) delivery via recombinant

OBJECTIVE To investigate whether cortical superficial siderosis (cSS) is associated with increased risk of future first-ever symptomatic lobar intracerebral hemorrhage (ICH) in patients with cerebral amyloid angiopathy (CAA) presenting with neurologic symptoms and without ICH. METHODS Consecutive

Human hereditary cerebral hemorrhage with amyloidosis of the Dutch type (HCHWA-D), an autosomal dominant form of cerebral amyloid angiopathy (CAA), is characterized by extensive amyloid deposition in the small leptomeningeal arteries and cortical arterioles, which lead to an early death of those

To clarify where and how beta-amyloid begins to deposit in senile plaques, we examined the ultrastructural localization of amyloid beta protein (Abeta) in diffuse plaques of brains with hereditary cerebral hemorrhage with amyloidosis-Dutch type. Alzheimer disease (AD), and from nondemented aged

Four cases of spontaneous intracranial hemorrhage (ICH) are described in which the diagnosis of a cerebral amyloid angiopathy (CAA) was made in the biopsy specimens. In one further case CAA was detected on autopsy after intracranial hemorrhage (ICH). Amyloidotic degeneration of the vessel walls

Cerebral amyloid angiopathy (CAA) is an important cause of spontaneous intracerebral hemorrhage in the elderly. A few case reports of CAA-related intracerebral hemorrhage after head injury, usually following a fall, have been published. More rarely, it may occur in the setting of a traffic accident,

Cerebral amyloid angiopathy (CAA) is the second most common cause of non-traumatic intracerebral haemorrhage (ICH) accounting for 12-15% of lobar haemorrhages in the elderly. Definitive diagnosis of CAA requires histological evaluation. We aimed to evaluate the spectrum of cerebrovascular changes in

Background: Amyloid precursor protein (APP) is highly expressed in platelets. APP is the precursor to amyloid beta (Aβ) peptides that accumulate in cerebral amyloid angiopathy and plaques in Alzheimer disease. APP and its metabolites

Cerebral amyloid angiopathy (CAA) predisposes to symptomatic intracerebral hemorrhage (sICH) after combined thrombolytic and anticoagulant treatment of acute myocardial infarction. However, the role of CAA in stroke thrombolysis has not been established. Here, we describe a confirmed case of

Amyloid-β-related angiitis (ABRA), a subtype of cerebral amyloid angiopathy (CAA), is vasculitis occurring in relation to amyloid-β (Aβ) deposition in the walls of intracranial blood vessels. ABRA is presumed to be caused by some immune response to the deposited Aβ. An 81-year-old man on oral

When most doctors encounter older patients with transient focal neurological symptoms, they usually suspect a diagnosis of transient ischemic attacks or some of their known mimics (including migraine auras or focal seizures). This article emphasizes new observations on transient focal neurological

OBJECTIVE To assess the interaction of cerebral amyloid angiopathy (CAA) and arterial hypertension as cofactors for intracerebral hemorrhage (ICH). METHODS The authors investigated 129 postmortem brains of hypertensive patients with and without ICH. Sixty-four patients had had deep (n = 40) or lobar

Cerebral amyloid angiopathy (CAA) is a degenerative disorder characterized by amyloid-β (Aβ) deposition in the brain microvessels. CAA is also known to contribute not only to cortical microbleeds but also lobar hemorrhages. This retrospective study examined CAA pathologically in patients who

A 92-year-old man died of multiple lobar hemorrhage with amyloid-β protein (Aβ)-related angiitis (ABRA) with an unusual pathological appearance. Although he had shown relatively rapid progressive dementia, starting 1 year before death, there was no detailed clinical investigation, and no
