a STROKE occurs when the human brain is deprived of blood supply. This can happen when a blood vessel has ruptured (broken) or, as is more common, is blocked by a clot along the direction towards the brain. It could be the right-brain or the left-brain.
The lack of fresh oxygen damages, or even kills, brain cells and disrupts functions controlled by the affected part of the brain. Because the blood brings vital oxygen and nutrients to our brain, while SIMULTANEOUSLY removing carbon dioxide (CO2) and cellular waste, this deprivation can have devastating effects if not treated medically at once.
There are basically TWO MAJOR KINDS of strokes:
Ischemic Strokes and Hemorrhagic Strokes, along with subtypes that run the gamut from lacunar and cerebellar strokes to the so-called "silent stroke." Most attack come silently and suddenly due to the many survival modes the body able to adopt automatically to survive another day. Stroke is just another of survival modes the body activates to prevent further deterioration due to cellular dehydration. Revise earlier postings to learn the dehydrating effects that lead to strokes. My papa restricted his own water intake during his train journey from Malaysia to Singapore recently. His reason was he found the way to the train's toilet shaky and upon reaching Woodlands Checkpoint he was feeling very weak that he could not walk. That's a common mistake many senior citizens made during long journey or traveling, and many had suffered the dehydration effects unknowingly.
The formation of blood clots is considered to be the main risk factor for heart attack or stroke.
Ischemic Strokes The most common type of stroke - comprising 85 % of all strokes - is the ischemic stroke.
This occur when something ( a blood clot, fatty material, or some other organic matter) blocks or obstructs an artery leading to the brain and cuts off the blood supply of oxygen-bearing blood, thereby depriving the brain of the oxygen it needs to function properly.
Located in the part of the human brain on the lower backside of the skull, above the neck, the cerebellum controls balance and coordination. Symptoms of this kind of stroke can mimic those of vertigo or food poisoning -- vomiting, dizziness, difficulty walking straight,etc. As with all strokes, IMMEDIATELY medical ATTENTION is EXTREMELY important to RECOVERY.
Transcient Ischemic Attack (TIA)
One common subtype of an ischemic stroke is a transient ischemic attack (TIA) (sometimes called "a mini stroke" or a "warning stroke"). One senior citizen sister suffered this type of 'baby-stroke' while she went to help her daughter in London to babysit her newborn grandson. To date, one side of her limbs were still in stroke condition.

This is usually very brief and not permanently damaging. Unlike a full-blown stroke, a TIA is a temporary interruption of blood flow to the brain when little bits of foreign matter lodge in small blood vessels in the brain. When this interrupts the smooth flow of blood to an area of the brain, that area ,left or right hemisphere, stops functioning until the bits of vascular rubble are dissolved. Surgery is only a temporary measure to help this condition. Because the real underlying cause is the body chronic dehydration at the cellular level.
These episodes are brief, lasting from minutes to hours, with full recovery within twenty-four hours. They should not, however, be ignored : in the world, more than a third (33%) of individuals , commonly among the senior citizens, who experience a TIA will have a stroke within five(5) years. Reason is simple, as a person gets older the thirst signal grow weaker till the person could not even feel the thirst even though the body is already undergoing chronic dehydration at the cellular level. Please help our senior citizens by monitoring their daily water intake, use water-cure protocol to remind them to drink 10% of daily quota, every 90 minute. They need our reminder and concern to prevent further afflictions.
A hemorrhagic stroke occurs when a damaged or diseased blood vessel in the brain ruptures, resulting in bleeding in the brain. For obvious reasons, this is colloquially know as a "bleeder."
Like most strokes, a hemorrhagic stroke is caused by high blood pressure. Prolonged-dehydration will cause the body to activate higher pressure outside the cells in order to service the cells which were surrounded by cholesterol cells. This is hypertension. Cholesterol forms an essential constituent of all scar tissue formed during wound healing, whether it is a skin-related injury or a lesion in the wall of an artery. Cholesterol is 97% water, acting as "wet-nurse' to the injured cells it is covered until the healing is completed. Due to wrong paradigm in the present medicine schools we have many graduated students continue on the tradition of using anti-cholesterol drugs to bring down the high level cholesterol in the patients. Sad and expensive mistake for all the patients and families, as the trend continue with "business as usual", till death do we part.
Compared to ischemic strokes, however, these kinds (hemorrhagic strokes)of events are relatively rare - only 12% of all strokes are of this type.
