Summary
This case report highlights cerebral amyloid angiopathy in an elderly patient presenting with stroke-like symptoms. Early diagnosis is crucial as antiplatelet drugs may increase microbleed risk in these individuals.
Area of Science:
- Neurology
- Neuroradiology
- Geriatrics
Background:
- Cerebral amyloid angiopathy (CAA) is a common cause of non-traumatic intracerebral hemorrhage in the elderly.
- CAA is associated with cognitive decline and dementia.
- Acute cerebrovascular events can mimic other neurological conditions.
Purpose of the Study:
- To describe a case of an elderly patient with CAA and dementia presenting with acute cerebrovascular symptoms.
- To emphasize the importance of accurate diagnosis in managing patients with CAA.
- To highlight the potential risks associated with antiplatelet therapy in this population.
Main Methods:
- Case report of an elderly patient.
- Clinical presentation review.
- Computed tomography (CT) and magnetic resonance imaging (MRI) analysis.
- Review of diagnostic criteria for CAA.
Main Results:
- Patient presented with symptoms suggestive of an acute cerebrovascular event.
- CT scan indicated a possible ischemic event.
- MRI revealed diffuse parenchymal lesions and hemosiderin deposits, confirming CAA.
- The patient had associated dementia.
Conclusions:
- Accurate diagnosis of cerebral amyloid angiopathy is critical in elderly patients with cerebrovascular events.
- Antiplatelet therapy, including aspirin, may be associated with an increased risk of microbleeding in patients with CAA.
- Careful consideration of anticoagulation and antiplatelet strategies is necessary in this patient group.

01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
01:19Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
01:26Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...
