A silent stroke (or asymptomatic cerebral infarction) is a stroke that does not have any outward symptoms associated with stroke, and the patient is typically unaware they have suffered a stroke. Despite not causing identifiable symptoms, a silent stroke still causes damage to the brain and places the patient at increased risk for both ...
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
If symptoms last less than 24 hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. [3] Hemorrhagic stroke may also be associated with a severe headache. [3] The symptoms of stroke can be permanent. [5] Long-term complications may include pneumonia and loss of bladder control. [3]
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Ischemia is a vascular disease involving an interruption in the arterial blood supply to a tissue, organ, or extremity that, if untreated, can lead to tissue death. It can be caused by embolism, thrombosis of an atherosclerotic artery, or trauma. Venous problems like venous outflow obstruction and low-flow states can cause acute arterial ischemia.
The recurrent artery of Heubner, Heubner's artery or distal medial striate artery [1] is a branch of the anterior cerebral artery.It supplies the head of the caudate nucleus and adjacent part of the anterior limb of internal capsule, olfactory regions, [2] and parts of the putamen and septal nuclei.
At least one person is dead after an outburst of severe weather blitzed the central United States late Monday into Monday night, including an EF4 twister that hit Barnsdall, Oklahoma, marking the ...
Other causes of intraparenchymal hemorrhage include hemorrhagic transformation of infarction which is usually in a classic vascular distribution and is seen in approximately 24 to 48 hours following the ischemic event. This hemorrhage rarely extends into the ventricular system.
