I had a severe headache last night couldn’t sleep whole night for the pain. So I went and had a bath around 6AM in the morning but failed to manage the pain. My wife woke up at 7 AM and found me so disturbed with the pain. She poured some Navaratna menthol hair oil on my head and gave me a massage. The pain reduced little bit after the massage and then I slept.
Today while reading an article about brain attacks in a local magazine, I thought of writing something about this common and highly increasing problem.
Every year millions of people from around the world are dying by strokes. Though people often thinks that strokes happen only to the elderly people, but 20 to 30 percent of all strokes occur in people under 45 years of age. Strokes are the second most common cause of death after cancer. Heart disease comes a close third.
In fact since most strokes kill brain cells from a lack of oxygen to the brain, strokes cause more disability in adults then any other disease. After a stroke some people can’t walk, others may have difficulty seeing or talking. People are affected differently, depending on what part of the brain was hit and how large an area was affected.
Most of the strokes are ischaemic, caused by a blockage in an artery leading to the brain. Around 20 percent of strokes are haemorrhagic, caused by bleeding in the brain or in the space between the brain and the skull.
Many of the same factors behind heart disease contribute to stroke. High blood pressure and high cholesterol can cause artery walls to become coated with plaque. In the narrowed arteries, a blood clot can form on the plaque and stop the flow of blood or move in to a brain artery and block it. Very high BP can also cause blood vessels in the brain to burst, resulting in haemorrhagic stroke. Uncontrolled diabetes, excessive weight, smoking all adds to the risk. Heart disease itself can increase your chance of having a stroke.
Treatment:
An MRI or CT scan can confirm the presence and location of a clot in a key artery leading to the brain. Doctors now have drugs that can break up a clot and help someone with ischaemic strokes. But the same medicine cannot be used for a haemorrhagic stroke; it makes the bleeding worse. Clot busting drugs only works if they are given within three hours of the onset of symptoms.
How do you recognize a stroke:
The main symptoms come on suddenly. They may include weakness, confusion, and difficulty in speaking or understanding speech and an inability to see properly. Some people also get a sudden, severe headache or experience dizziness. The symptoms depend on which part of the brain is affected.
As soon as you have the attack, rush to a hospital, which have an imaging center for MRI or CT scan. Once the doctor establishes that the patient has had a stroke, and which kind of stroke it is, they can determine the course of treatment.
Early warning signal:
Some strokes go unnoticed because they are short episodes lasting up to 24 hours. These are sometime calls stroke warnings or mini strokes. The medical term is TIA. The symptoms of TIA are like those of regular strokes, but they don’t last long. Because people generally seem to recover well from TISs, they often ignore them or put off doing anything about them.
It is important to pay attention to mini strokes. Even when people have a mini stroke and recover with no disability. According to a medical journal, 30 percent of people who have TIAs gone on to have full-blown stroke with in five years.
So for stroke patients, timely hospitalization is the key to recovery.
