A brain stroke can affect anyone at any point of time when the supply of blood to the brain is interrupted. It can threaten major physical functions and can prove to be fatally dangerous at times. The brain stem which is placed right above the spinal cord controls the breathing, heartbeat and levels of blood pressure. It is also in charge of controlling some elementary functions such as swallowing, hearing, speech and eye movements. 

What are the different types of strokes?
There are three main kinds of stroke: ischemic strokes, hemorrhagic strokes and transient ischemic attacks. The most common type of brain stroke is the ischemic stroke is caused by narrowing or blocking of arteries to the brain, which prevents the proper supply of blood to the brain. Sometimes it so happens that the blood clot that has formed elsewhere in the body have travelled via the blood vessels and has been trapped in the blood vessel which provides blood to the brain. When the supply of blood to a part of the brain is hindered, the tissue in that area dies off owing to lack of oxygen. The other variant of brain stroke is termed as hemorrhagic stroke is caused when the blood vessels in and around the brain burst or leak. Strokes need to be diagnosed and treated as quickly as possible in order to minimize brain damage.  Remembering the F.A.S.T. acronym can help with recognizing the onset of stroke (Face, Arms, Speed, Time - explained below). 

What are the common symptoms of a brain stroke?
The symptoms of the brain stroke are largely dependent on the area of the brain that has been affected. It can interfere with normal functioning, such as breathing and talking and other functions which human beings can perform without thinking such as eye movements or swallowing. Since all the signals from the brain as well as other parts of the body traverse through the brain stem, the interruption of blood flow often leads to numbness or paralysis in different parts of the body.

Who is likely to have a stroke?
Anyone is at a risk of developing brain stroke although ageing is directly proportional to the risk of having a stroke. Not only that an individual with a family history of brain stroke or transient ischemic attack is at a higher risk of developing stroke. People who have aged over 65 accounts for about 33 percent of all brain strokes. It is important to point here that individuals with high blood pressure, high blood sugar, cholesterol, cancer, autoimmune diseases and some blood disorders are at a higher risk of developing brain stroke.

There are a few factors which can increase the risk of developing stroke beyond any control. But there are certain lifestyle choices as well which aids in controlling the chances of being affected by stroke. It is crucial to refrain from long-term hormone replacement therapies as well as birth control pills, smoking, lack of physical activity, excessive use of alcohol and drug addiction. A brain stroke is a life-threatening medical condition, and when an individual has symptoms that resemble that of stroke, it is crucial to seek immediate medical help.

Treatment for stroke

Treatment depends on the type of stroke.
Ischemic strokes can be treated with 'clot-busting' drugs.
Hemorrhagic strokes can be treated with surgery to repair or block blood vessel weaknesses.
The most effective way to prevent strokes is through maintaining a healthy lifestyle.
What is TPA?
TPA is a thrombolytic or a  Clot Buster  drug. This clot buster is used to break-up the clot that is causing a blockage or disruption in the flow of blood to the brain and helps restore the blood flow to the area of the brain. It is given by intravenous (IV). This can be given only within 4.5 hrs of the onset of symptoms

Time is brain

Remember Every second Loss means brain cells die.
Rush to the nearest Stroke Centre whenever you experience such symptoms.
U can save the brain cells dying if you reach within 4.5 hrs by the CLOT BUSTER. 
Endovascular procedures 
Another treatment option is an endovascular procedure* called mechanical thrombectomy, strongly recommended, in which trained doctors try  removing a large blood clot by sending a wired-caged device called a stent retriever, to the site of the blocked blood vessel in the brain

Stroke prevention
The good news is that 80 percent of all strokes are preventable. It starts with managing key risk factors, including 

High blood pressure,
Cigarette smoking,
Diabetes
Atrial fibrillation and
Physical inactivity.
More than half of all strokes are caused by uncontrolled hypertension or high blood pressure, making it the most important risk factor to control. 
Rehabilitation
The best way to get better after a stroke is to start stroke rehabilitation ("rehab"). In stroke rehab, a team of health professionals works with you to regain skills you lost as the result of a stroke.

Brain Stroke - Things You Must Know!

Chemotherapy has been the remedy for cancer since the late 90s. But in today s world the medical field has been improved so much that new methods have been invented. One of them is Hormonal therapy. It is used to cure some types of breast cancer that are affected by hormones. Receptor proteins in the breast cancer cells attach to estrogen and help the cells grow. This therapy stops the receptors attaching to estrogen in various ways.

When it is used?
Hormonal breast cancer therapy is performed after surgery to prevent the cancer from coming back. It is also applied to treat the cancer that has come back or to prevent the cancer from spreading to other parts of the body. Sometimes, if needed, it starts before the surgery. It takes five years, generally.

How it works?
Hormonal therapy mainly stops estrogen from acting on the cancer cells or lowers the estrogen level. There are different ways to do that.

Blocking Estrogen Receptors: These drugs stop estrogen from helping breast cancer cells.
Tamoxifen: It acts as anti-estrogen in the breast cells, but acts like estrogen in other cells. It lowers the risk of breast cancer and also stops cancer from coming back.
Toremifene: It works in a similar way, but it is only used in metastatic breast cancer. It also decreases the pain and swelling in the muscles and bones.
Fulvestrant: It blocks and damages estrogen receptors. It is given by injections after other drugs stop working.
Lowering Estrogen Levels: These drugs slow the growth of cancer by lowering estrogen levels.
Aromatase Inhibitors: These drugs stop estrogen production in women whose ovaries are not working due to menopause or other treatments. There are three types of this drug- Letrozole, Anastrozole and Exemestane.
Ovarian Suppression: In this method, ovaries are removed or shut down to turn pre-menopausal women to post-menopausal. There are several ways to do this, and they are- Oophorectomy or surgery, LHRH analogs and applying chemotherapy drugs.
There are some other types of hormone therapy that are less common. They were used more in the past. They are:

Megestrol acetate
Androgens
High doses of estrogen
Side Effects:
Unfortunately, Hormonal breast cancer therapy has lots of side effects. They are-

Hot flashes
Mood swings
Vagina discharge or dryness
Developing uterine cancer
Blood clots
Stroke
Night sweat
Headache
Mild nausea
Bone pain
Injection site pain
Muscle pain and joint stiffness and pain
Bone thinning
Menopause
Although hormonal therapy has lots of side effects, they are limited to different kinds of hormonal therapies and it is not necessary that they will surely happen. But it is best to undergo any kind of treatment with a doctor s advice. So patients should consult the doctor first.

Brain mapping is a technique where the biological quantities of a human brain are represented as spatial quantities resulting in maps. As with many other medical technologies, brain mapping is fast-evolving as well. Among several uses, brain mapping is chiefly used while performing surgery on the brain.

When surgery is to be performed on the brain such as surgery for epilepsy, the surgeon would want to comprehend how the brain areas are affected by seizures. The surgical intervention is meant for removing as much as seizure focus as possible while preserving crucial functions like understanding, speech, vision, movement, and sensation.

Why is brain mapping performed?
Brain mapping is a process which helps in identification of functions of various parts of the brain. Mapping the brain by stimulating different areas of the brain areas can aid in creating a map for a particular person. The map allows the doctor in understanding what parts of the brain are responsible for performing critical functions including sensation, movement, speech and other functions.

Which functions of the brain can be mapped electrically?
Typical areas of the brain which have motor, language, visual and sensory functions are needed to be mapped. When current is applied to a single area at a time, the doctor understands which part of the brain is responsible for which function.
When the patient is not able to speak due to the current, then the area is likely to be crucial for language function. If the limbs, face or trunk of the patient stop moving as the current passes, the area that is tested is responsible for movement. On the other hand, if the individual experiences tingling, numbing, and other sensations when the current is applied, it means that a sensory region is discovered.

How is electrical brain mapping performed?
Electrical brain mapping for guiding brain surgery for epilepsy can be performed in two distinct processes: directly during the surgery or in a two-stage procedure.

Two-stage procedure:
In the first stage of the process, the surgeon creates an opening in the skull which helps in exposing the surface of the brain. Small electrical contacts or electrodes are placed on the brain surface even though no brain tissue is removed. As soon as the electrodes are in the right position, the scalp is closed. The electrodes not only record the seizure of the patient electrically but also allow mapping of various areas of the brain. The last stage is surgery where abnormal brain tissues are removed.

Brain mapping process during surgery:
Electrical brain mapping may also be performed during the surgery which exposes part of the brain. This is termed as intraoperative brain mapping since it occurs while performing the main operation. The process of mapping may last for an hour to several hours at a stretch.

Brain mapping is also used to diagnose neurodegenerative diseases like Alzheimer s and Parkinson s. In these cases, the brain map shows extreme shrinkage of the brain due to tissue loss.

Brain Mapping Surgery - Why It Is Performed?

Bone cancer is a cancerous tumour in the bone, destroying the normal bone tissues. Tumours on bone tissues are not always cancerous or malignant, they are mostly benign. Primary bone cancer is when the malignant tumour begins to form in the tissues of the bones, but when these cancerous cells spread to other body parts like breasts, prostate or lungs, it is called metastatic cancer. Primary bone cancer is less common than metastatic cancer.

Bone cancer can be of three different types:

Osteosarcoma: In this case, the malignant tumour arises from the osteoid bone tissue. This occurs mainly in the upper arm and knee areas.

Chondrosarcoma: In this case the cancerous cells form in the cartilaginous tissues, causing a lot of pain. This occurs mostly in the pelvic area.

The Ewing sarcoma generally arises in the bone but it can also form in the soft tissues. Other kinds of soft tissues affecting cancerous cells are known as soft tissue sarcomas.

Causes-

There aren t many clear defined causes; however, several factors have been identified by researchers.

Osteosarcoma is seen to occur more frequently in people who have been through a high external radiation therapy dose.

In people who have frequently been treated with anticancer medications, children tend to be most affected.

Heredity may be an adding cause, although the percentage of hereditary transfer of cancer cells is very low.



People with hereditary bone defects or implants have a higher chance of acquiring bone cancer.

Symptoms-

The most common and saddening symptom of bone cancer is painful, although not all bone cancers cause pain. Unusual or persistent swelling or pain around a bone maybe a red flag for bone cancer. In case of a situation like this, immediate doctor s opinion is required.

Diagnosis-

Usually, diagnosis of a bone cancer can be made using X-rays; for example, a bone scan, a computed tomography scan, a magnetic imaging procedure positron emission tomography, and an angiogram. Biopsy and blood tests are also helpful in bone cancer diagnosis.

Treatment-

The size, location and stage of cancer, age, and health of the person decide the kind of treatment that should be given to the patient. Various treatment options include chemotherapy, radiation therapy and cryosurgery.

Survival-

The combined survival rate of all sorts of bone cancers is 70%. This percentage may vary with the type of bone cancer and also its stage.

An Overview Of Bone Cancer

Breast cancer begins when the cells that are present in the breast start to go out of control. These cells generally form a tumor which can be seen on mammogram or one can feel it as a lump. The tumor is threatening if the cells can grow into the tissues that surround it or spread to other areas of the body. Breast cancer happens mostly in ladies. Here are a few methods with which you can prevent breast cancer-

Keep your weight in check: Maintaining a healthy weight is important for everyone although, it is easy to tune it out since it is said so often. Being overweight can expand the danger of a wide range of cancers, including breast cancer, particularly after menopause.
Be physically active: Women who are physically active for almost or at least 30 minutes a day have a lower danger of breast cancer. Normal activity is additionally one of the ideal approaches to keep weight under control.
Eat Your Fruits and Vegetables and Avoid Too Much Alcohol: A balanced and healthy diet can bring down the danger of breast cancer. Attempt to eat a considerable measure of fruits and vegetables and keep liquor at moderate levels or lower. While moderate drinking can be useful for the heart in most grown-ups, even low levels of intake can build the danger of breast cancer. If you do not drink, don't feel you have to begin. In case you drink modestly, there is less risk.
Try not to Smoke: Smokers and non-smokers alike know how undesirable smoking is. It brings down a person s quality of life and expands the danger of heart and lung diseases, stroke, and no less than 15 types of cancer, including breast cancer. It additionally causes bad breath, awful teeth, and wrinkles.
Breastfeed, If Possible: Breastfeeding for almost one year or more brings down the danger of breast cancer. It additionally has extraordinary medical advantages for the baby as well, especially in terms of immunity.
Keep away from Birth Control Pills: Contraceptive pills have both dangers and advantages. In many cases, the more young a lady is, the lower the danger is. While ladies are taking birth control pills, they have more chances of falling prey to breast cancer as per various medical studies. This danger leaves rapidly in the wake of stopping the pill. The danger of stroke and heart attack is increased while on the pill, especially if the woman smokes. Long term use can likewise have essential advantages, such as bringing down the danger of ovarian cancer, colon tumor and uterine cancer and undesirable pregnancy. In case you are exceptionally worried about breast cancer, staying away from birth control pills is also an alternative to lower the risk.

Breast Cancer - 6 Ways You Can Prevent It!

The treatment options for bone cancer depends on the type of cancer one is suffering from, the general health of the patient, the stage of cancer and the general preference of the patient. Different treatment options are designed for different types of cancer, based on the diagnosis. Each treatment responds in a different way. An oncologist decides the treatment options considering all the factors mentioned above. For instance, some cancer is best suited to surgery, while some cancer needs radiotherapy or chemotherapy to curb them. In many cases, all three modes of treatment might be required to tackle the growth of the cancer cells.

Surgery:
The goal of surgery is to eradicate the cancer cells in totality along with some surrounding healthy tissues. This involves special techniques to remove a tumor in one piece. Following are the types of surgeries that are available:

Removing the cancer cells sparing the limb: At the very first sight, the surgeon tries to understand whether it is possible to separate cancer cells from the tissues and the nerves. If the same is possible, the surgeon tries to save the limb while getting rid of the cancer cells. For the sake of safety and to ensure that the surgery is effective, the surgeon removes some of the healthy bone from the body and may replace the same with tissue from other parts of the body. To achieve this, a doctor might seek the help from of a bone bank or use a special metal prosthesis.
Surgery that does not involve the limbs: If the bone cancer does not involve the legs and the arm, surgeons can remove the affected bone along with some healthy bone from the surrounding areas. Cancer of the ribs and the spine are good examples of this type.
Surgery that affects the limb: Bone cancer that has spread to a significant extent and is strategically located in such areas that it is very difficult to remove, requires amputation. While this form of treatment is being increasingly discouraged by the wider medical community, it still does exist. In such cases, patients are fitted with artificial limbs and trained to do their job without the use of natural limbs.
Chemotherapy:
This is a form of drug treatment that uses powerful chemicals to kill cancer cells throughout the body. This medication is mostly given through an IV and the medication kills whatever cancer cells it comes across. 

Radiation therapy:
Radiation therapy involves the usage of special X-ray beams that have high power and can kill cancer cells. The patients are required to lie on a table, while a machine moves around the affected area and treats it with high energy X-rays, thereby killing the cancer cells. Radiation therapy is often used in conjunction with chemotherapy to reduce the size of a tumor before operating on it.
