Reversible cerebral vasoconstriction syndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. [1] Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. [1]
Congenital diseases are medical conditions that are present at birth that may be associated with or inherited through genes. [16] Examples of congenital cerebrovascular diseases include arteriovenous malformations, germinal matrix hemorrhage, and CADASIL (cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy).

Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Cranial venous outflow obstruction, also referred to as impaired cranial venous outflow, impaired cerebral venous outflow, cerebral venous impairment is a vascular disorder that involves the impairment of venous drainage from the cerebral veins of the human brain. [1] [2] The cause of cranial venous outflow obstruction is not fully understood.
Encephalopathy is a difficult term because it can be used to denote either a disease or finding (i.e., an observable sign in a person). [citation needed] When referring to a finding, encephalopathy refers to permanent (or degenerative) [11] brain injury, or a reversible one. It can be due to direct injury to the brain, or illness remote from ...
People with vascular dementia may also present with general slowing of processing ability, difficulty shifting sets, and impairment in abstract thinking. Apathy early in the disease is more suggestive of vascular dementia. [2] [5] Rare genetic disorders that cause vascular lesions in the brain have other presentation patterns.
A vascular surgeon permanently connected the artery and vein in Thomas’s left forearm, creating a fistula that would enable the rapid blood flow through the dialysis machine. First, he must ...
It may imitate, and is in turn imitated by, a number of other diseases that affect the blood vessels of the brain diffusely such as fibromuscular dysplasia and thrombotic thrombocytopenic purpura. [3] Primary CNS vasculitis has an incidence of 2.4 cases per 1 million people, with an associated mortality of 8-23% and a 25% risk of severe ...
