Brain edema, BBB disorders / repetitorium

Prerequisites and co-requisites: tissue fluid production, HEB permeability, paraventricular organs.

Edema
Fluid accumulation in the brain - increase in brain volume - due to the pressure-volume curve increase in intracranial pressure

Classification


 * vasogenic
 * cytotoxic
 * osmotic
 * hydrostatic
 * ischemic (combination of vasogenic and cytotoxic)

Consequences - intracranial hypertension - restriction of blood flow to the brain! Symptoms identical to intracranial hypertension.

BBB

 * Development during life (newborns)
 * Disorders - inflammation, ischemia, radiation
 * Increasing system pressure
 * ECT osmolality changes (water poisoning)
 * Drug permeability (ATB, dopamine)
