In simple words when an artery in the brain is blocked it causes Ischemic stroke.
The arteries carry blood to all the organs in our body including heart, lungs and brain. If any artery is blocked, then the part of the brain does not get sufficient blood/oxygen and hence that part of the brain stop functioning. If the person does not get proper & immediate treatment then slowly other organs of the body may also stop functioning – Since the brain controls the functioning of different organs in our body.
Ischemic stroke can be due to various reasons. The most common reason is contraction in the arteries that go to the neck and brain. It can be due to the accumulation of atherosclerosis, cholesterol or triglyceride that can block the arteries. Another reasons could be sometimes arteries develop blood clot due to irregular heart beat, heart attack or asymmetry in the shape of heart valves, which hinders the blood supply and cause stroke.
Sometimes Ischemic stroke can be due to any accident, tension or death of a loved one.
As we said earlier brain controls the functioning of various organs,when there is an Ischemic stoke it leads to other health problems such as brain atrophy, contraction of brain, Alzheimer, multiple scleroses, cerebral palsy etc.
In Ischemic stroke doctors usually suggest physiotherapy. Alternative medicine suggests electro magnetic field therapy which can dissolve the blood clot in arteries and normalize the blood circulation. However these are not complete solution as they cannot revive the brain cells that are dead, but these therapies can definitely controls any further damage.
In this regard RTMS ( repetitive transcranial magnetic stimulation ) and PEMF ( pulse electro magnetic field) are worth mentioning. The patient is required to wear a helmet like device for 1-2 hours and sleep. Through magnetic stimulation these devices try to energise the brain cells. RTMS & PEMF have been found to be beneficial in many brain related problems.
