[48] [51] [52] MSC treatment also appears to improve the control of cerebral blood flow and blood–brain barrier permeability, [53] [54] as well as what is currently thought to be the most important mechanism of MSC treatment after stroke, the activation of endogenous neuroprotection and neurorestoration pathways by the release of cytokines ...
Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
Cerebral amyloid angiopathy may cause intraparenchymal hemorrhage even in patients without elevated blood pressure. Unlike hypertension, cerebral amyloid angiopathy does not typically affect blood vessels to deep brain structures. Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2]
[13] [14] [15] Hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes. [13] [16] Bleeding may occur due to a ruptured brain aneurysm. [13] Diagnosis is typically based on a physical exam and supported by medical imaging such as a CT scan or MRI scan. [9]
Transcranial doppler ultrasound analyzer of blood velocity. Transcranial Doppler (TCD) and transcranial color Doppler (TCCD) are types of Doppler ultrasonography that measure the velocity of blood flow through the brain's blood vessels by measuring the echoes of ultrasound waves moving transcranially (through the cranium).
Cerebral softening, also known as encephalomalacia, is a localized softening of the substance of the brain, due to bleeding or inflammation. Three varieties, distinguished by their color and representing different stages of the disease progress, are known respectively as red, yellow, and white softening.
People require double antiplatelet therapy for a period of up to 3 months after the procedure and aspirin therapy for up to 1 year. In a systematic analysis of 19 studies with 207 cases, there was an 87% improvement in overall symptom rate and 90% cure rate for treatment of papilledema.
Cranial ultrasound is a technique for scanning the brain using high-frequency sound waves. It is used almost exclusively in babies because their fontanelle (the soft spot on the skull) provides an "acoustic window". A different form of ultrasound-based brain scanning, transcranial Doppler, can be used in any age group.
