After a blow ischedmique, the fact how much time takes of ordinary one for the brain growth to peak &the amplifier; to lower itself?I ask this question for the case of a big blow ischedmique in which around 2/3 left side of the brain was diminished. Probably it takes longer for the brain growth to lower itself for a big blow than a blow minor.
A continuation question is, which is the mechanism by which the brain growth lowers itself? Does the growth lower itself only because of the death of cells of brain?
Good day.
After a blow ischedmique, there is in does two types of growth of brain (aka the cerebral edema) that arrives.
1. First, there is the intracellular edema, that also is called the edema of cytotoxic. When a cell of cerveau's provision of oxygen is interrupted, the cell no longer is able to regulate the concentration of its own edlectrolytes. Consequently, while the cell dies, the water hastes in the cell of the compartments extracellulaires. This event arrives in some hours (2-3 hrs) after the blow arrives.
2. The second type of edema is called the edema of vasogenic (aka the edema interstitiel) and arrives later than the edema of cytotoxic. In this case, after a blow ischedmique, the sanguine vessels break down downstream and begin fleeing water and proteins in the sector of dead brain. These events arrive with 6-12 hours and the progress for almost 3 days.
When someone has a big blow, the this is the quick progression of edema interstitiel that is potentially mortal. The estimated summit of edema interstitiel is almost 3 days, but realistic it this is almost 3-5 days.
Finally as the neurones and its cells supporting die and are replaced with scar fabric, the edema of cytotoxic lowers itself. Also, as the sanguine vessels repair themselves or or die, the leakiness of the sanguine vessels lowers themselves also. Thus, reply to your question, the growth resolution is not directly because of the neurone death, but the this is had rather to the decrease of inflammation and the gradual repair of the sanguine vessels.
Hope that I could reply to your question!
Do you mean a paralytic blow?
Practically there is the small remedy for a paralysis itself resultant of a blow (ie., the cerebral thrombose).
A brain cell this of once dead means is of a permanent dead manner! The source (the sources) : Doctor
