Stroke or Aptly Called Brain Attack

Posted by drugvilla on August 30th, 2019

When the brain cells controlling a particular function of the body loose their capacity to perform it due to sudden sussesion - stoppage of his blood  supply results in it distruction and hence corresponding parts loosing it function called paralysis.Brain controls the half of the body and therefore the paralysis occurs on the side opposite in which this clot has occured in brain.If the area of the brain with a cutting of the blood supply occurs controls movement of the opposite half of the body when it losses movement called hemipegia or half paralysis.Simlarly part of brain controlling speech (left) thus affected then produces loss of speech or aphasia  whereas language controlling area getting affected by such stroke would produce abnormal words,garbage language or strange language occasionally confused as a psychiatric disease.

Stroke if it involves vision area of the brain it produces loss her vision in the opposite part of eye field area.However certain areas of the brain when they get stroke do not produce loss of power in the limbs or speech produce abrupt onset of abnormal psychotic deliarious behavior ,mimicking,acute sight,ksytic illness where is despite having good strength in the limbs a person may not be able to stand in a balanced manner and walks in an unsteady fashion.When cutting of the blood supply occurs in the balancing center of brain call ceribellum it's worth noting that double vision also occurse on a menephestation of brain stroke which also produces difficulty in sorrowing whether the artery suppling the brain gets blocked by clot with in its lumen called as thombosis (inside the artery) or it leaks and rupture called hamrage and this also result in no supply to specific part of the brain.

In both the events there is a clot wheather inside the artery or outside the artery where the leaked blood from the artery clots.As a main road gets blocked the traffic moves towards it's destinations through alternative roads called collotonals.But cutting of the blood supply in brain has a core central area of unrecoverable destraction of brain cells called infract which is surrounded by non functioning of thousands (millions) of unconcious brain cells which can be salvaged.The therapeutic modalities currently in the use focus on preperfusing these unconscious brain cells and helping them to sustain their diminishing energy producing capacity.

Prevention and stroke is by attacking the risk factor specially blood pressure,diabeties and lipid profile management and reducing the cloting tendency of blood by giving blood thinner like medicines.people can still have stroke in the absence of above risk factors requiring detailed investigation. Surgery to restablish the blood supply through artery in a already established full fledged stroke will not give risk to recovery but can prevent future attacks in certain specific situation only.

the scientific neurology world is unanimous in treating brain hamrages by surgery when hamrage occurs in cerebellum whereas opinions are divided when it comes to surgery for brain hamrages in other location and the conclusion is that a very small percentage of brain hamrages get benefitted surgical evacuation of the clot.
