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!

There are two primary factors that are more likely to cause a stroke in a person i.e age and a family history. While both are inevitable, this necessarily doesn t have to be the fate of a person. Brain stroke is entirely preventable as with the case of other diseases. By working on the potential health risk factors, a stroke can be prevented. Here is a list of few such steps which, when followed can pay rich dividends to a person facing the risk of a brain stroke:

Blood Pressure: Blood pressure is the single most important factor that can increase the chance of a brain stroke. If a perfect blood pressure reading seems too difficult to achieve, a more realistic blood pressure target of 140/190 should be aimed for. Some of the common steps in order to achieve an acceptable blood pressure figure include reducing salt in the diet, exercising on a daily basis, regular intake of fresh fruits & vegetables and fast processed food containing processed fats. Finally, quitting drinking and smoking goes a long way in ensuring that a person is safe from strokes.

Losing Weight: Obesity increases the risk of diabetes and blood pressure subsequently increasing the risk of a stroke. Being overweight, therefore greatly increases the odds of a stroke. A BMI of 25 should be maintained by engaging in activities such as walking, running and playing on a daily basis.

Regular Exercise: Exercise is a clear mandate for people facing an increased risk of brain strokes. A moderate intensity exercise schedule for a minimum of 5 days per week is necessary. Some simple steps in order to achieve this include taking the stairs while climbing, joining a fitness club, 30 minutes of daily walk in a day etc.

Moderate Drink: Surprising as it may sound, moderate drinking on a daily basis can dramatically reduce the risk of a brain stroke. Red wine should be the choice of preference in this case. It should be ensured that the level of drinking does not surpass more than a glass. Regular drinking in excessive quantity can increase the chance of brain stroke.

Check For Atrial Fibrillation: This is a disease that is related to the heart due to an irregular heartbeat. There is a possibility of the clots travelling to the brain causing a brain stroke. Certain possible symptoms of this disease such as palpitation of heart and shortness of breath should be checked with a doctor to negate the chance of brain stroke. Certain blood thinners like warfarin and aspirin can shield against atrial fibrillation. A doctor has to be consulted before starting any medication related to the heart.

Top Ways To Prevent A Brain Stroke

Although surgery is considered to be the first step of treatment in any form of tumor, but its feasibility depends upon the type, size and location of the tumor. It is not necessary that every kind of brain tumor might require surgery.

Indications of Brain Tumor Surgery
- Diagnosis of the type of tumor by taking a sample of the tumor for laboratory examination
- Complete resection of tumor
- Removal of the tumor as much as possible to slow down its growth and improve the symptoms
- Remove the tumor in order to help other treatment
- Provide direct access for other forms of treatment like chemotherapy, radiotherapy etc.
- To relieve pressure caused by tumor on surrounding structures

Types of Brain Tumor Surgery
The different types of surgery that are performed in cases of brain tumor include the following:

Craniotomy: Craniotomy is the most commonly performed procedure to remove brain tumor along with a piece of bone. The removed bone is replaced and the tumor is sent for histopathology (biopsy). The surgery is performed using a high end microscope by any of the following techniques:
- Extended bifrontal craniotomy
- "Eyebrow" craniotomy (supraorbital craniotomy)
- "Keyhole" craniotomy (retro-sigmoid craniotomy)
- Orbitozygomatic craniotomy
- Translabyrinthine craniotomy

Shunt: A narrow piece of flexible tube with a pressure regulated valve in between is called a shunt. This is used to relieve the intracranial pressure caused by obstruction of the natural brain fluid, Cerebrospinal fluid (CSF) pathway by tumor mass. The procedure involves insertion of a drainage system into the brain to remove or drain excess of blocked fluid into the peritoneal cavity.

Stereotactic surgery: This surgery is done by creating a three dimensional image called stereotaxy using computers. It aims to find out the location and position of the tumor. In fact it can also be done to aid tumor removal, implant radiation pellets or for other treatments.

Embolization: It is a procedure used to reduce the amount of blood supply to a tumor by blocking the blood flow in the selected arteries. It is generally performed before the main surgery.

Endoscopy and endoscope assisted surgery: Endoscope is a tool, which helps to closely visualize the tissue through small openings in difficult to reach areas. This tool can be used in various brain surgeries to precisely reach the target location without damaging the adjacent structures.

Adjuvant modalities to improve outcome: In addition to above mentioned surgeries, following surgeries may also be performed in relation to brain tumor treatment:
- Laser surgery
- Photodynamic laser surgery
- Ultrasonic aspiration
- Fluorescence guided surgery (FGS)
- Electrophysiological monitoring

Brain Tumor Surgery

Brain surgery involves several medical procedures, which incorporate fixing issues with the brain, including changes in the tissues of the brain, cerebrospinal fluid and brain blood flow. Brain surgery is quite a complicated method of surgery and the type of surgery to be conducted depends on the underlying conditions.

Reasons for Brain Surgery:
Brain surgery is performed for the correction of physical brain abnormalities. These abnormalities could occur because of diseases, birth defects and injuries. A brain surgery is required when the following conditions arise in the brain:

Abnormal blood vessels
Aneurysm
Bleeding
Blood clots in the brain
When the protective tissue or dura is damaged
Epilepsy
Due to nerve damage
Parkinson's disease
Any kind of pressure after an injury
Abscesses
Skull fractures
In case of stroke and tumors
A surgery may not be required for all the above mentioned conditions, but in case of many, a brain surgery is very important as the conditions may worsen health problems.

Types of brain surgeries:

Craniotomy: During this open brain surgery, an incision is made in the scalp, and a hole is created in the skull, near the area, which is being treated. After this process is complete, the hole or bone flap is secured in its place using plates or wires.
Biopsy: This form of brain surgery helps in the removal of a small amount of brain tissues or tumors. After removal, the tissues or tumors are examined under a microscope. The creation of a small incision and a hole in the skull is indicated as a part of this process.
Minimally invasive endonasal endoscopic surgery: This form of brain surgery enables the removal or lesions and tumors via the nose and sinuses. Private parts of the brain can be accessed without creating an incision. An endoscope is utilized in the process which is used to examine tumors all across the brain.
Minimally Invasive neuroendoscopy: This process is similar to the minimally invasive endonasal endoscopic surgery. This method also involves the use of an endoscope for removal of brain tumors. Small, dime sized holes may be made in the skull to access some brain parts.
Risks:
Brain surgeries may be associated with several risks. They may be:

Allergic reactions to anesthesia
Bleeding
Blood clot formations
Swelling of the brain
A state of coma
Impairment in speech, coordination and vision.
Problems in memory
Strokes and seizures
Infections in the brain
A brain surgery is a serious and very complex surgery. There are different kinds of brain surgeries, which are conducted depending on the condition and severity of the disease.

Brain Surgery - When It Is Required?

A tumor is an uncontrolled and abnormal growth of cells. A brain tumor is thus an abnormal growth and multiplication of cells in the brain. The cell growth can also be in areas adjacent to the brain. The brain tumor may

Have its origin in the brain (Primary brain tumor), or
Its origin may be in some other parts or organs of the body, which gradually spreads to the brain (Secondary/metastatic brain tumor).
Not all brain tumors are harmful and life threatening.

Brain tumors that exist as noncancerous cell growths are known as Benign brain tumors. Benign brain tumors seldom pose any threat to life.

Brain tumors that are cancerous and, thus, harmful, are known as Malignant brain tumors.

Do not neglect any brain tumors (malignant or not). It is better to be safe than to be sorry.

Types of Primary brain tumors:

Based on its cell of origin, primary brain tumors (benign as well as malignant) may be of the following types:

Meningiomas: Brain tumors that originate from the meninges (the membranes that cover the brain and the spinal cord). Meningiomas are seldom malignant.
Acoustic Neuromas: A noncancerous cell growth that has its origin in the vestibulocochlear nerve (the eighth cranial nerve). This nerve connects the brain with the inner ear.
Gliomas: Here, the tumor has its origin in the brain and the spinal cord (glial cells). This type of brain tumors, in most cases (~80%), are malignant.
Primitive Neuroectodermal Tumors (PNETs): Extremely rare, PNETs are malignant tumors that develop in the embryonic cells in the brain.
Medulloblastomas: Medulloblastomas is a malignant brain tumor that mostly affects children. It originates in the cerebellum (lower part of the brain).
Craniopharyngiomas: A benign brain tumor that has its origin near the pituitary gland (base of the brain). Craniopharyngiomas are common in children.
Probability of a secondary brain tumor are more in people who have had;

Kidney cancer
Breast cancer
Lung cancer
Colon cancer
Melanoma
Symptoms:

The symptoms of brain tumor include:

Chronic and regular headaches.
A change in the headache pattern.
Seizures.
A person may experience vision problems (Peripheral vision may be affected, double or blurred vision).
There may be difficulty in hearing.
Nausea and vomiting.
Behavioral and speech problems.
An arm or a leg may lose sensation.
A person has difficulty with balance.
Diagnosis and Treatment:
Though brain tumor can affect anyone and everyone, its chances are higher in

People who are more exposed to ionizing radiation. People having undergone a radiation therapy are equally vulnerable.
Children as well as older people.
People having a family history of brain tumors.
The diagnosis includes;

An imaging test like the MRI, CT scan and PET (Positron Emission Tomography).
Biopsy, whereby samples of the abnormal tissue is collected and examined.
Neurological examination.
Treatment:

Surgery is an effective treatment for brain tumors.
One can also opt for:

Radiations, whereby the abnormal tumor cells are destroyed using protons and x-rays (high-energy beams).
Chemotherapy: In this treatment, the tumor cells are destroyed using strong drugs (taken orally or intravenously).
Radiosurgery.
Targeted drug therapy: This treatment blocks the abnormalities that are characteristically present only in the cancer cells.

Brain Tumors: Types, Symptoms, Diagnosis, and Treatment

The most powerful and amazing organ in our body is the brain. It differs from many other organs of our body not only by its shape, but also by its special type of cell called neurons. When these cells gets affected or dead it can never be reverted or regenerated which is the most exclusive nature found only in brain cells. The cells in other parts of our body has the capacity to regenerate (can be replaced or new one can be grown or produced), but brain cells are exception. Hence any damage to the brain, injury or trauma is really a crucial thing to be considered with utmost care.

Brain surgeries really need skill, proper training, confidence and intelligence to perform this highly complicated and risky surgery.

Purpose:
Brain surgeries are performed to:

Remove the brain tissues that are grown abnormally
Aneurysm is clipped to prevent flow of blood cliff off an aneurysm
Biopsy purpose or to remove the tumour
Make a nerve free
Drain the abnormal blood or clot collection or to drain any excessive fluid collection caused by infection.
To implant artificial electronic device as a treatment for conditions like Parkinson's disease
Types:

Biopsy: A part of brain tissue is removed for the brain or whole tumour is removed.
Craniotomy: The skull bone is opened to remove tumour, an aneurysm and drain fluid or blood from infection.
Minimally invasive endonasal endoscopic surgery: Endoscopic devices are inserted through the nose to remove the lesions or tumour.
Minimally invasive neuroendoscopy: Similar to endonasal surgery but small incision is made.
Risks:

Anaesthesia risks like breathing difficulty, allergic reaction to medications, excessive bleeding or clots and infection.
Risk related to the brain surgeries are seizures, coma, swelling of brain, infection to brain or meanings, surgical wound infection that intrudes to the brain structures, abnormal clot formation and bleeding.
General risks include muscle weakness, disturbances in memory, speech, vision, coordination, balance and other functions that are controlled by the brain.
