A stroke may be called a brain attack. It may happen to any person at any time. A stroke occurs when blood supply to the brain is cut off. The brain cells become oxygen deprived due to the stroke and eventually die. Dead brain cells result in brain dysfunction due to which patients lose control over muscle and memory.

Strokes can be mild to life threatening and requires immediate medical attention. Stroke requires advanced care and should be treated by extensively qualified and experienced medical experts. 

Neurosurgery satisfies all the required clauses for treatment of stroke and accounts for being one of the best ways for management of stroke. Renowned hospitals have a dedicated neurosurgical wing and a team of neurological specialists who know how to deal with stroke the best.

Vascular Neurology
This form of neurology focuses on patients who have undergone a stroke or have experienced symptoms of stroke. A multidisciplinary approach is taken for the prevention of recurrent cerebrovascular conditions.

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. This form of stroke is the more common. The underlying cause of this stroke is known as atherosclerosis, which is a condition where fatty deposits occur in the walls of the blood vessels and cause blockage in them.
Hemorrhagic stroke: This type of stroke occurs when a blood vessel gets weak and ruptures into the brain. This is caused by two types of weak blood vessels known as aneurysm and arteriovenous malformation.
Transient ischemic attack: This type of stroke is also known as a mini stroke. These attacks occur because of blood clots. The blockage caused is temporary or transient in nature.
Treatment of Ischemic stroke

Tissue Plasminogen Activator: This is one of the best ways to treat ischemic strokes. 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 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. 
Treatment of Hemorrhagic stroke

Endovascular procedure: Several endovascular techniques and methods are used so that the weakening of blood vessels is reduced and less bleeding is caused.
Surgical treatment: Different modes of neurosurgery may be undertaken to stop bleeding and for relieving pressure within the skull.

Role of Neurosurgery in Management of 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.


7 Signs You Are Having A Stroke!

5 simple ways to prevent dandruff in winter

Dandruff is becoming increasingly common. This scalp condition can exacerbate in winter since the humidity of the air around you decreases, which results in dry skin and an itchy scalp. But there are certain ways in which you can prevent the onset of dandruff during winters. Read on to find out.

1. Wash your hair with lukewarm water
You may find a shower with hot water a great way to start your day, but unfortunately, it has a negative effect on your scalp. Hot water baths are responsible for scalp irritation and effectively increase inflammation, which ultimately leads to the occurrence of dandruff. So, always opt for lukewarm water to wash your hair in order to maintain the natural moisture level of your scalp.

2. Give your scalp a coconut oil massage
Make it a habit to massage your scalp with 3-5 tablespoons of coconut oil before sleeping at night. Rinse away the oil the following morning using a gentle shampoo. Regularly following this remedy proves to be beneficial in keeping dandruff away from your scalp.

3. Watch your diet
You can ensure that your scalp remains healthy during winters by including moderate amounts of vitamin b, omega 3 fatty acids and zinc in your diet. To get these nutrients eat foods like walnuts, leafy vegetable, and eggs etc. These foods can help in keeping your scalp hydrated, thus preventing the occurrence of dandruff.

4. Stay away from hair styling products
Winter robs away the moisture from your scalp, which makes it highly vulnerable to damage on exposure to harsh chemicals. Most hair styling products (such as hair colours) contain strong chemicals, and if you use them frequently during the winters, you may end up having an itchy scalp resulting in dandruff later.

5. Use conditioners and shampoos containing tea tree oil
Hair care products like shampoos and conditioners made of tea tree oil help in restoring moisture to your scalp, which in turn stops dandruff from occurring. Alternatively, giving your scalp a tea tree oil massage two times every week works wonders for your hair and keeps dandruff at bay.

Seeing a Sudden Rise in DANDRUFF? Here?s What You Need To Do!

High blood pressure can lead to hypertension, which is known to cause a variety of debilitating side effects or symptoms in the life of the patient. It can also lead to a number of related ailments which can affect the various organs of the body. The eyes are one of the organs that are most susceptible to this kind of spike in the body s blood pressure. Let us learn more about the connection between the two.

Retina: When high blood pressure goes untreated for a prolonged period, it can easily start to affect the blood vessels that can be found in the retina. The retina is the third or the inner most layer of the eye which is sensitive towards light and usually helps in refraction. This is where the light reaches so that one can focus clearly on an image. When the blood pressure of the patient stays high for a prolonged basis, there is significant pressure on the blood vessels in this part of the eye which can lead to an eye disease known as hypertensive retinopathy.

Symptoms: Symptoms of this eye disease include lack of clarity and focus when the eye comes to rest on an object, as well as headaches and other vision problems that typically spring from eye strain that one will go through while trying to focus even harder. It may be seen that the symptoms do not appear in the very early stages of this disease.

Diagnosis: The diagnosis of the condition is usually done by an ophthalmologist who will use an ophthalmoscope in order to project light towards the specific part of the eye so that the back of the eyeballs can be examined. The signs that the doctor will look for during the examination include narrowing of the blood vessels in this part of the eye, inflammation of the macula which is the central portion of the retina, and bleeding in the back of the eye. Also, the doctor will check for spots in the retina with the help of cotton swabs and exudates.

Treatment: The best and only way of treating this condition is by keeping one s blood pressure in control with the help of medication prescribed by the doctor.

Prevention: There are many ways of preventing the onset of this disease, including losing weight so that there is less pressure on the body. Also, one must stick to a healthy diet and exercise regularly after taking recommendations on the appropriate exercises from the doctor. Additionally, it is also important to see a doctor on a regular basis so that there is constant monitoring and regulation of the medicines and the blood pressure.

Blood Pressure - How it Affects Your Eye Sight?

Runny nose is a condition when one s nostrils keep on discharging a fluid. This happens due to congestion and inflammation of the linings of nasal passages and sinuses and is caused mostly by a viral infection known as common cold. Allergy or Sinus infection lead to the swelling of inner linings of nose and sinus. Inflammation caused by virus increases seepage of fluid from the blood vessels into the lining of the nose and also into the nose. This leads to swelling up of nose lining resulting into blockage of air flow and a runny nose.

One can refer to some safe and natural home remedies for runny nose that can give relief from this very uncomfortable condition and help expel the fluid comfortably. If one is experiencing other symptoms like a fever, cough, and or sore throat in addition to runny nose, then visit doctor to treat the underlying cause. Try to determine the reason for a runny nose as the causes of runny noses dictate the potential cure. If it is due to allergies then one can take antihistamine and if is due to cold/sickness then take steam and use decongestants. If it dues to clogging then blow nose and try and clear the irritant. Most of the times, it can be due to sleep deprivation.

One must clean out nose regularly by blowing it through when the nose is runny. If one is not able to get the irritant out of your nostrils, try nasal irrigation product. 
Gently massage nose and area between eyes and earlobes to ease sinus pressure to slow down the flow of a runny nose. Apply light pressure to each nostril, closing and opening them slowly followed by rubbing above eyes and on ear lobes. 
Use steam to ease discomfort by reducing the mucus produced by runny noses. One can take a hot shower or bath, turn on a humidifier, or lean over a bowl of hot water.
Try medication and supplements to further manage symptoms. There are a variety of prescription and over the counter medication to help manage runny nose. Nasal sprays, containing olopatadine, vapour rubs and topical decongestants, Magnesium and zinc supplements can help open up cells and nasal passageway.
Apply pressure down ten times on the corner of the nose very gently to keep one s nose from getting worse. This pressure point can help alleviate sinus congestion and headaches that are due to colds and allergies. The nose should be almost closed each time pressure is applied to the area. The same procedure needs to be done on the area just above
Use salt water to flush out the nasal passages, freeing up mucus. One can either use a syringe or other product designed for nasal irrigation. Soak a hand towel in hot water and place it on the face to alleviate sinus pressure and open up the nasal passages.
A supplement of Magnesium 400mg oral pills can help blood vessels dilate and restore blood vessel responsiveness in the mucous producing glands. Oral Zinc supplements of 15mg benefits intracellular pathways that cause secretions like mucous.

6 Simple Home Remedies To Stop Runny Nose

Pulmonary Function Tests or PFTs are a set of tests that are used to determine, measure or observe the functioning of the lungs. The most common pulmonary function tests used are spirometry, gas diffusion, and lung plethysmography. 

Highlights of pulmonary function tests

A spirometry test is used to measure the amount of air inhaled and exhaled. It also measures the amount of time taken to complete a respiration cycle.
A lung plethysmography measures the amount of air in the lungs after the patient has taken a deep breath. It also measures the amount of air that remains in the lungs after the patient has exhaled as much air as possible.
What does a Pulmonary Function Test measure?
Pulmonary function tests would not only check how well the person is breathing but also how effectively the lungs are able to conduct oxygen to the rest of the body. In addition to air flow, these tests would measure the size and volume of the lung and lung diffusion.

These tests can also be used to measure

Total Lung Capacity   the amount of air present in the lungs after breathing in deeply
Forced Vital Capacity   the amount of air that can be exhaled after breathing in deeply
Minute Volume   the amount of air exhaled per minute
Vital Capacity   the total volume of air that can be breathed out after inhaling as much as possible
Tidal Volume   the amount of air inhaled or exhaled when breathing normally
Maximum voluntary ventilation   the amount of air that can be inhaled and exhaled in one minute
Functional Residual Capacity   the amount of air that remains in the lungs when breathing normally
Forced Expiratory Flow   the flow or volume of air during an exhalation
Peak Expiratory Flow Rate   the rate at which a person can exhale
When are Pulmonary Function Tests recommended?
A physician might recommend a patient undergo a PFT as part of a routine physical check-up. This test would be advised if the patient is experiencing any symptoms associated with lung problems or disorders such as asthma, respiratory infections, chronic obstructive pulmonary disease, COPD. A doctor would also use these tests to monitor and check whether a certain treatment prescribed for a lung disease or condition is working effectively.

Pulmonary function tests are safe as they are non-invasive but it is important to follow the instructions of the doctor or technician before, after and during the test. It is important to make your doctor aware of any surgeries, respiratory infections, chest pains or heart attacks that you might have experienced before the test. If you are taking any medications you might need to follow the advice of the doctor as to whether you can take them before the test.

Your doctor would also advice you on how to prepare for the test such as not eating a large meal, avoiding caffeine and wearing loose-fitting clothes. If you have any doubts, concerns or queries discuss them with your doctor.
