Stroke - Symptom, Treatment And Causes

Stoke happens when the blood supply to the brain is either reduced or interrupted. When this condition happens, the brain cells do not get adequate oxygen or nutrients which causes the tissues in the brain to die. As being said, strokes occur due to impaired blood supply to the brain. So it happens either the blood supply channel has been blocked or some blood vessel in the brain has ruptured.

There are mainly three types of stroke:

  • Ischemic stroke
  • Hemorrhagic stroke and
  • TIA (Transient Ischemic Attack)

Ischemic Stroke

This is the most common form of stroke, which account for more than 85% of strokes all across the globe. This type of stroke is a result of blocked or narrowed arteries, which sends blood to the brain. Arterial stenosis (narrowing) subsequently results in severe, reduction in blood flow to the brain. The block in arteries often happens because of blood clots. These clots can either get formed inside the main arteries that connect to the brain, or even in the narrowing arteries that are within the brain. These clots are mostly formed by fatty deposits within the arteries, which are medically known as plaque.

Hemorrhagic stroke

This kind of stroke happens mainly due to leaking or bursting arteries that spilled blood inside the brain. The leaked blood from the arteries puts pressure inside the brain and damages the cerebral tissues. Blood vessels during a hemorrhagic stroke can burst in the middle of the brain or near the surface of the brain cells, leaking blood into the cellular space between the brain and the skull. Hemorrhagic stroke can happen because of conditions such as trauma, hypertension, weakening in the vessel walls (aneurysm) or because of blood thinning medications like heparin and others. Intracerebral hemorrhage is the most prevalent type of hemorrhagic stroke. Subarachnoid hemorrhage, which is less common is the next type that happens during a stroke. In this case bleeding happens in the area the area between the brain and the thin tissue that separates it from the cranial bones, medically referred as the subarachnoid space.

TIA (Transient Ischemic Attack)

TAIs are a little different from the other two forms of strokes. In this case the blood flow to the brain gets interrupted for a very brief period of time as it happens in ischemic strokes. TAIs are often caused by small blood clots in the arteries. However, nevertheless TAIs are also considered as medical emergencies, since they can be real warnings for future strokes. It has been found left untreated TAI patients have major strokes within a period of one year after getting affected with TAI.

Since it’s an absolute medical emergency, call a doctor immediately, if found that you or anyone near you has been identified with symptoms of stroke.

7 Signs You Are Having A Stroke!
Stroke is a condition known to all for its deadly impact. Even if the affected person survives, the after-effects can be immensely debilitating right from affecting movement to speech. Being informed, you can protect yourself and your loved ones from both ischemic and hemorrhagic stroke. Here are the common signs of stroke that you should be aware of: Numbing of arms and legs: Many people wake up and find that their arms and legs are numb and they tend to assume that it is due to compression of the nerve. But the actual reality is that the flow of blood through the arteries running up to the spine is reduced, and it has led to weakness or numbness on either side of the body. Double vision and blurriness: Vision problems can also be a strong indicator of stroke even though most people think it is due to long hours of work or aging. When you see two images of the same object, it doesn t have to mean that you are reading too much. It could mean that the blood vessel in charge of supplying oxygen to the eyes has been disrupted or blocked. Slurred speech: Some medicines, particular painkillers can cause speech issues. But this is not the case always; if it is not a side effect that you typically experience after taking painkillers, you should consult a healthcare expert without any delay. Confusion and trouble over thinking and articulating: When you find yourself in a state where you cannot recall the right word to explain the right thing, you may rest assured that it is an issue stemming from the stroke. If you find yourself to struggle thinking or finding a word very commonly, then you are heading for big trouble. Balance problems: Some people have balance issues, and they think it is due to the dose of alcohol, but experts say it is crucial to identify whether this assumption is correct. You will never have delayed balance problems, and therefore, you cannot blame a drink that you had last day. So, if you have balance issues without any identifiable reason, it is advisable to call a doctor. A headache that becomes intolerable at times: Headaches can be a sign of a migraine but in case you are not prone to this ailment, then the debilitating headache could indicate a stroke. Migraine headaches can also mean stroke since both of them have similar signs and symptoms. Fatigue that won t let you stay upright: If you are not doing any physically strenuous job but still feel tired most of the time, it could be a warning sign of stroke. If it continues for over a week, it is recommended that you consult an expert immediately. Equipped with this knowledge, stay aware and pay attention to the indications your body gives to take care of yourself.

What Tests Can Be Done To Identify The Stroke?
Strokes occur when blood to the brain gets interrupted or reduced. When this occurs, brain cells begin to die as they don't get enough nutrients and oxygen. Such life-threatening episodes can strike you anytime. There are certain signs that can help you to clearly recognise an occurrence of stroke: Face drooping on one side Weakness or numbness on one side of the body, usually a leg or an arm You're unable to think or say anything clearly You experience slurred speech Difficulty in moving your tongue You get a sudden and severe headache Causes A stroke occurs when the blood supply to your brain is interrupted or reduced. This deprives your brain of oxygen and nutrients, which can cause your brain cells to die. A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke). Some people may experience only a temporary disruption of blood flow to their brain (transient ischemic attack, or TIA). What Tests can be Done to Identify the Stroke? There are certain tests that you can do to identify these warning signs. To identify facial weakness, the smile test is used wherein you're simply asked to show your teeth to check for any changes in this facial expression - a lopsided smile. To check for weakness in the body, the arm test is performed in which you raise both your arms to the same height. In case you're unable to do so, you may be experiencing arm weakness, a sign of stroke. For slurring of speech, you may be asked to repeat sentences such as 'Don't cry over spilt milk' or 'The pen is mightier than the sword'. Stroke can also be identified through the walk test wherein with the help of another person, you walk across the room to check for changes in your step. If not treated in time, strokes can cause permanent brain damage. More importantly, unlike heart attacks, anxiety may not always be the cause of your stroke symptoms. That's why, being aware of these symptoms and recognising them on time can help you to quickly seek medical assistance. Endocrine causes of hypertension leading to stroke frequently go undiagnosed in cases such as Pheochromocytoma, Conn's syndrome, Cushing's syndrome, etc.

Stroke Due To Hypertension - How To Prevent It?
High blood pressure, which is often a result of hypertension, is the leading risk factor for a stroke, which in turn leads to severe and long-term disability, including death. Managing your blood-sugar levels is the most critical thing you can do to lessen your risk of a stroke, and you should leave no stone unturned in keeping your blood pressure at optimum levels. What causes a stroke A stroke, which is often referred to as a brain attack, takes place when the supply of blood to a particular region of the brain is cut off. The brain cells which are deprived of the oxygen and glucose die, and when the ailment is not caught early, a permanent damage to the brain can follow. How is high blood pressure related to a stroke Uncontrolled blood pressure levels can increase the risk of a stroke by about four to six times. With the passage of time, hypertension causes atherosclerosis as well as hardening of major arteries. This often results in blockages of small blood vessels present in the brain. With high blood pressure for a long period of time, the blood vessels of the brain become weak and burst. This way the risk of a stroke is directly related to the high levels of blood pressure. What can you do to keep your blood pressure under control There is a lot you can do to keep the chance of a stroke at bay. But the first thing you should try doing is keeping your blood pressure level normal. Some simple lifestyle changes can help you to lead a risk-free life and therefore, you should first aim at shedding off those extra pounds along your waistline. In general, a man with a waistline measuring over 40 inches and a woman with that over 35 inches is at a higher risk of suffering from high blood pressure as well as a stroke. You should exercise regularly for at least half an hour and eat a well-regulated diet loaded with fibre, proteins, potassium and Omega-3 fatty acids. Stay away from junk food and maintain a food diary where you can jot down your honest food habits. It is very important to lower down your high blood pressure in order to avoid risks of stroke. But if you fail to do so even after following a healthy routine, then it is crucial to consult a doctor who can help you by prescribing medications that are right for your medical condition.

3 Types Of Stroke You Should Know!

3 Types Of Stroke You Should Know!
A stroke may be called a brain attack. It may happen to any person at any time. A stroke occurs when there is a vascular event in the brain causing a blockage of blood vessels or a rupture of vessels causing hemorrhage. The brain cells are starved of food and oxygen or are assaulted by a barrage of harmful agents released as a result of hemorrhage, suffering reversible or irreversible damage. Dead or disabled brain cells result in brain dysfunction due to which patients may lose control over parts of the body or lose the capacity to speak, think or remember. Strokes can be mild to severe and require immediate medical attention. Stroke requires advanced care and a stroke patient is ideally treated by a multidisciplinary team of experts. At various stages of treatment, the attention of doctors specializing in Neurology, Neurosurgery, Critical Care, Medicine, Radiology and Physical Medicine may be required. Besides, good nursing care and physiotherapy are essential for better recovery from stroke. Types of Stroke- Ischemic Stroke: This kind of stroke occurs when there is a blockage in a blood vessel, which supplies blood to the brain. The commonly seen underlying causes are atherosclerosis (which is a condition where fatty deposits occur in the walls of the blood vessels) or embolism (blood clot formed elsewhere reaches the brain circulation and blocks a smaller blood vessel). Other rarer causes of ischemic stroke are trauma, hypotension, vasospasm, etc.. Hemorrhagic Stroke: This type of stroke occurs when a blood vessel ruptures into the brain. This can be caused by high blood pressure, weakened vessel wall due to atherosclerosis, or vascular malformations like aneurysms, AVM, or cavernomas. Transient Ischemic Attack: This type of stroke is also known as a mini-stroke. The blockage caused is temporary or transient in nature, and may happen repeatedly. Treatment of Stroke: A. General Treatment: Most cases require supportive management to prevent the secondary complications of stroke, so that the patient gets adequate time for the brain tissue to recover functions. Medicines are administered to control brain pressure, prevent convulsions and aid brain tissue recovery. Paralysis of muscles, difficulty in eating, drinking, breathing, controlling urine etc. make the patient highly dependent. Physiotherapy is essential for good recovery of impaired functions. It is essential for family and friends to encourage the patient and involve themselves in supportive care to prevent depression from setting in and for robust rehabilitation. B. Specific Treatment of Ischemic Stroke Tissue Plasminogen Activator: This is one of the best ways to treat ischemic strokes presenting early. This medicine is given to the patient intravenously. It dissolves the blood clot and improves blood flow to the area of the brain which is affected. The medicine should be given within three to four hours after stroke symptoms appear. Endovascular procedure: This is again useful only if the patient reaches early. This is a process by which the blood clot is removed using a catheter, which gets inserted into the area of the blocked blood vessel. It helps in restoring blood flow to that area. Decompressive craniectomy: Large ischemic strokes cause a rise of brain pressure which may cause death. To reduce brain pressure, decompressive craniectomy surgery may be required if medicines alone are not effective. In this, a large part of the skull on one side or in the front may be removed to allow space for a swelling brain and relieve intracranial pressure. C. Specific Treatment of Hemorrhagic stroke Surgical treatment: Different modes of neurosurgery may be undertaken to remove blood clots, repair vascular malformations and for relieving pressure within the skull. The need for surgery depends on the cause, location and volume of hemorrhage besides other factors. It is an important decision, and the family needs to consult with the neurosurgeon and understand the implications thoroughly before agreeing or disagreeing for treatment. Endovascular coiling or embolisation: Act as standalone treatment or as an additional aid to surgery especially in vascular malformations like aneurysms or AVMs.

How To Prevent Brain Stroke?
As the famous quote says, 'prevention is better than cure', let us take you through some preventive measures to keep you and your loved ones away from the dreadful consequences of brain stroke. Brain stroke occurs due to an interruption in the regular blood flow to the brain or rupture of a blood vessel causing brain cells in the affected area to die or become disabled. Stroke is a vascular disease, so anything that keeps the blood vessels healthy can reduce the risk of stroke. Top 8 things that will reduce the likelihood of having a brain stroke: Eat well: Having good eating habits are not just good for a healthy outlook of the body, but also benefits the body in many other ways. Eating plenty of fresh fruits and vegetables, lots of fibre, reducing salt and saturated fat intake can keep blood vessels healthy and reduce the risk of stroke. Stay Active: Regular exercising not just makes you feel and look good, but also reduces the odds of developing a brain stroke. Exercising regularly keeps the heart and brain vessels healthy. Say no to Smoking and drugs: Yes! The more you smoke, the more are the chances of suffering a deadly brain stroke. Control your blood pressure: The ideal blood pressure for a healthy person is 120/80 mm of mercury. Regular check-up of blood pressure is advisable to control the chances of suffering a stroke as high blood pressure can directly cause a brain hemorrhage. Drink in limits: Limit the amount of alcohol you consume. Chronic alcoholics suffer from malnutrition and liver problems which compound the chances of stroke and its severity. Alcoholic liver disease causes blood clotting to be impaired, increasing the chances of stroke.Consulting a de-addiction specialist is the best option in case you are not able to control your alcohol intake. Cholesterol: People suffering from high cholesterol are at higher risk of strokes as the cholesterol can deposit in the wall of arteries in the body making the arteries narrow and the body more prone to suffer a stroke. Reducing saturated fat like red meat, dairy fat etc., and increasing MUFA like mustard or olive oil can help reduce cholesterol. Diabetes: uncontrolled high blood sugar over long periods is one of the most prominent reasons behind stroke. One should get his sugar level checked regularly, especially if there is diabetes in the family. Stress: Prolonged stress generally leads to high blood pressure and reduced body immunity, and hence becomes a reason for stroke. Consultation with a doctor and/or psychiatrist is advisable in case a person if suffering from stress or depression. Ultimately, improving your health and taking charge of your life should be the top most priority and should never be ignored at any cost.

If the doctors have suggested surgery it is mos likely that the stroke is causing brain swelling and the resultant increase in pressure is causing threat to life. Surgery is therefore life saving. Unfortunately it has no implication on physical recovery since that is dependent on the size of the stroke and part of the brain that is affected.
