There are several theories as to why these blood vessels may become inappropriately permeable and allow the surrounding brain tissue to become swollen. The "vasogenic" theory posits that elevated blood pressure overcomes the normal capability of blood vessels in the brain to maintain a normal cerebral blood flow .
Marketed as Curanail, Loceryl, Locetar, and Odenil, amorolfine is commonly available in the form of a nail lacquer, containing 5% amorolfine hydrochloride as the active ingredient. It is used to treat onychomycosis (fungal infection of the toe- and fingernails). Amorolfine 5% nail lacquer in once-weekly or twice-weekly applications was shown in ...
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]
Atherosclerosis is characterized by the build-up of plaque inside your blood vessels. It can lead to stenosis, which is a narrowing of your artery walls. Plaque is a fatty substance made up of:
New research in the journal International Immunopharmacology showed that obese people treated with a GLP-1 agonist had a 37 percent lower risk of Alzheimer’s disease, a 41 percent lower risk of ...
The blood–brain barrier is formed by special tight junctions between endothelial cells lining brain blood vessels. Blood vessels of all tissues contain this monolayer of endothelial cells, however only brain endothelial cells have tight junctions preventing passive diffusion of most substances into the brain tissue. [1]
The most definitive diagnostic modality is a biopsy of the affected blood vessel however brain biopsy has a low yield, with up to 30-50% of biopsies being normal in suspected cases. [5] This is due to some cases having an irregular distribution of vessel involvement (making biopsy technically difficult) or larger vessels being unable to be ...
When examining blood oxygen levels, scientists found that lower oxygen levels during sleep was correlated with both higher hippocampal volume and white matter hyperintensities, or areas of brain ...
