Ischemic and Hemorrhagic Stroke
Hopefully you never had to endure a situation of someone close to you to suffer from transient ischemic attach (TIA), also known as mini stoke, or from a stroke. In any case, you should be familiar with both kinds of stroke as they both destroy brain tissue and can produce similar long-term effects. But there are important differences in what causes them and in the symptoms that tell you which kind of stroke is happening.
Ischemic Stroke:
According to statistics, 80 percent of strokes belong to the ischemic stroke kind. These mini-strokes occur when blood flow to the brain is blocked by plaque-clogged arteries or by blood clots. This means that blood is not circulating properly inside the brain causing brain cells to die if even for a few minutes no oxygen is transmitted to them via the blood.
- Symptoms: Sudden numbness or weakness, especially on one side of the body; difficulty speaking or understanding speech; trouble seeing in one or both eyes; dizziness and a sudden loss of balance; falling in and out of consciousness; chest pain and shortness of breath. These last three symptoms are less-brain-centered and are more commonly experienced by women.
Hemorrhagic Stroke:
These brain hemorrhages happen when a blood vessel in the brain bursts, spilling blood into the surrounding tissue. There are various causes of these bursts. The most frequent is the rupture of an aneurysm, a weak spot on the wall of an artery that happens to be in your brain-aneurysms can occur elsewhere in the body, too. Experts point out that women are twice as likely as men to have an aneurysm in the brain and are more likely to have multiple aneurysms than men. Two other causes for bleeding in the brain are: hypertension, which can create enough pressure to break an artery wall, and arteriovenous malformation (AVM) in the brain. This is a snarl of defective blood vessels and capillaries whose thin walls are prone to rupture.
- Symptoms: A sudden violent headache, as if cracking a fault like through the brain’s delicate architecture. The patient may also suffer from blurred vision or nausea.
If you ever suspect you might be having a TIA or stroke or believe you are witnessing someone else having one, make sure 911 (or your local emergency unit) be called immediately. Tell the dispatcher that, if possible, you want to be transported to a hospital with a stroke center. Do not attempt to drive to the emergency room yourself. Stroke patients who arrive at the hospital by ambulance are evaluated sooner by an ER physician, get the necessary testing and are admitted to the hospital or intensive-care unit more frequently than those who arrive by taxi or car. Most importantly, bring someone prepared to advocate for you or the patient. Be prepared by being informed and act fast!

The Different Stroke Types
Stroke is a medical condition characterised by interruption of blood supply to the brain. This may happen of a blood vessel is blocked and stops blood from entering the brain or when there is a bleeding.
There are three types of stroke: ischemic stroke, intracerebral haemorrhage and subarachnoid haemorrhage.
Ischemic Stroke
The ischemic stroke is the most common type of stroke. Almost 80% of all stroke cases are of ischemic stroke. The ischemic stroke occurs when a blood vessel in the brain is blocked. Regular supply of fresh blood is vital to brains health. If a blood vessel is blocked, the brain cells cannot receive blood rich of oxygen and nutrients and they stop working. If the blood supply is stopped for more than a few minutes the brain cells start dying. The ischemic stroke may be caused by many reasons but the most common one is narrowing the arteries of the neck and the head. If the blood vessels become too narrow blood cells start to collect and form blood clogs. These clogs may block the blood vessel or dislodge and get closer to the brain and again clog the blood vessel. An ischemic stroke may be also caused by drug abuse, injury, or disorders of blood clotting.
Intracerebral Haemorrhage
The intracerebral haemorrhage stroke occurs when a blood vessel inside the brain bursts. In this case blood just leaks out causing high pressure to the cells that surround the leak. If the blood leaks out rapidly there might be a severe brain damage and even death. The intracerebral haemorrhage usually occurs in selected parts of the brain and that is why the damages may be to selected functions of the body. The intracerebral haemorrhage stroke is caused by high blood pressure and it may occur in people of all ages including children. Overall around 12% of all strokes are of this type.
Subarachnoid Haemorrhage
The subarachnoid haemorrhage occurs when a blood vessel just outside the brain bursts causing blood to leak out. The area of the skull surrounding the brain fills with blood and that is why people experiencing subarachnoid haemorrhage may feel sudden severe headache, neck pain, and nausea or vomiting. This kind of stoke is typical for people of all ages, especially for young adults and teenagers. It is more common for women than for men and is caused by a disease of the arteries. It may develop from birth or in childhood and grow very slowly.

An Introduction To Migraine Headache
Headache is one common problem that everyone faces. Like other sicknesses, even headache has its genres depending upon nature and causes of headache. Headache could be the side effect of some diseases or it may trigger because of constant stress that you may have been facing in your life. Although, most types of headache could be effectively cured but one genre of headache is yet to be offered a permanent cure. Yes! I am talking about migraine pain that is still shrouded with mystery.
Medical science is yet to ascertain exact causes of migraine headache. In most of the cases migraine pain disappears suddenly after troubling you for quite some time. But it may worsen a person’s condition if it is a recurring one. It happens when you are afflicted with classic migraine pain.
In rare cases, the pain is termed as Status Migrainosus. This migraine pain persists till you undergo severe medication and take sufficient rest. This type of migraine completely disrupts your schedule. You are needed to take a break and relax for a couple of days. However, majority of folks suffer from common migraine pain which makes you fall on the bed. You are resilient enough to quickly come back to your routine after a common migraine.
Seeing the gravity of migraine pain, you are not recommended to use over the counter pain killers to subside your pain.
Most of the medical researchers claim that migraine pain could be due to variation in serotonin level. Serotonin is a brain chemical that is said to have its effect on blood vessels going to brain. Blood vessels keep swelling and shrinking due to varying level of serotonin. This variation beyond the normal range results in to migraine. But, factual evidences have not yet proved the perfection of this medical theory regarding migraine.
It’s not necessary that only adults might suffer from migraine, even a child could suffer from migraine if he/she remains in stressful situations. Children afflicted with migraine must not be allowed to use non-prescription pain killers. Such children are suggested to perform breathing exercises and other relaxation exercises.
If you are facing a recurring migraine pain, you must also keep track of the frequency of recurrence. It happens to be of great help for doctors in suggesting medication by ascertaining the gravity level of migraine.
