  2. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    Cerebral perfusion pressure is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion). It must be maintained within narrow limits; too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), and too much could raise intracranial pressure.

  3. Cranial venous outflow obstruction - Wikipedia

    en.wikipedia.org/wiki/Cranial_venous_outflow...

    Impaired cranial venous outflow can lead to increased venous pressure, decreased cerebrospinal fluid (CSF) absorption, brain cortex hypoperfusion, brain edema, blood–brain barrier (BBB) disruption, inflammatory reactions, hemorrhagic complications, and increased intracranial pressure. [1]

  4. Cerebral vasculitis - Wikipedia

    en.wikipedia.org/wiki/Cerebral_vasculitis

    Possible secondary causes of cerebral vasculitis are infections such as with varicella zoster virus (chicken pox or shingles), systemic auto-immune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, medications and drugs (amphetamine, cocaine and heroin), some forms of cancer (lymphomas, leukemia and lung cancer) and ...

  5. Brain ischemia - Wikipedia

    en.wikipedia.org/wiki/Brain_ischemia

    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.

  6. Cerebral perfusion pressure - Wikipedia

    en.wikipedia.org/wiki/Cerebral_perfusion_pressure

    Cerebral perfusion pressure, or CPP, is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion).It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), and too much could raise intracranial pressure (ICP).

  7. Normal pressure hydrocephalus - Wikipedia

    en.wikipedia.org/wiki/Normal_pressure_hydrocephalus

    The fluid build-up causes the ventricles to enlarge and the pressure inside the head to increase, compressing surrounding brain tissue and leading to neurological complications. Although the cause of idiopathic (also referred to as primary ) NPH remains unclear, it has been associated with various co-morbidities including hypertension, diabetes ...

  8. Vertebrobasilar insufficiency - Wikipedia

    en.wikipedia.org/wiki/Vertebrobasilar_insufficiency

    Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex. [1]

  9. Intracranial pressure - Wikipedia

    en.wikipedia.org/wiki/Intracranial_pressure

    Idiopathic or unknown cause (idiopathic intracranial hypertension, a common cause in otherwise well people especially younger women) [citation needed] Craniosynostosis; One of the most damaging aspects of brain trauma and other conditions, directly correlated with poor outcome, is an elevated intracranial pressure.
