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?

Rubbery cushions (discs) between the bones (vertebrae) stack up to form the spine. When a nerve between the disc and vertebrae is pressed and inflamed, that condition is called herniated disc. The herniated disc is also referred to as the ruptured disc or the slipped disc. This is caused when the soft jelly is pushed out due to a tear in the exterior. Herniated discs can lead to an irritation of the nerves and result in tremendous pain. It may also cause the arms and legs to become numb and weak. However, some people suffering from this condition may not display any symptoms at all.

Herniated disc generally occur in the lower part of the vertebral column. The herniated disc may also be seen in the thoracic spine or cervical spine. The symptoms of a herniated disc include pain in the legs, feet, or the buttocks, pain in the shoulder blade, tingling of the feet, numbness of the feet and hands, muscle weakness, neck pain or muscle spasm in the neck. Most common causes of herniated discs are aging, excessive weight or lifting of heavy weight.

Prevention of herniated disc

Herniated discs are very commonly found in people who are aged between 35 or 55 years. They are seen more commonly in the men in comparison to the women.
A herniated disc cannot be prevented easily, but there certain things that you can do to reduce the risks. Maintaining the proper techniques of lifting is important. You should not be bending at your waist. You should always bend the knees and keep the back straight. This helps you to use your leg muscles which are very strong to support the weight.
As the saying goes, precaution is better than cure, so here are few precautions that can be taken to avoid herniated discs. Practicing a proper posture can help in reducing the risk of a herniated disc. It is extremely important for an individual to maintain a healthy posture while standing, sitting, walking, and even sleeping. It is imperative that you stretch your muscles when you are sitting in one position for a long time.
Another important thing to avoid is high-heeled shoes, as they are few of the most common causes of a herniated disc. It would be a good idea to go for flat and well cushioned comfortable footwear as they can go a long way in reducing the risk of the herniated disc.
Exercising regularly can go a long way in keeping the muscles of the legs, stomach, and back very strong. You should try to balance your flexibility and strength by exercising regularly. The best form of exercise to avoid herniated disc or ruptured disc is aerobic exercise.
It is true that as you start to age, the chances of getting a herniated disc increase significantly. However, if proper precautions are taken, the stress put on the spine can be effectively reduced, thereby eliminating the risk of a herniated disc. 

Herniated Disc - Is There A Way It Can Be Prevented?

Though breast cancer has become very common, the good news is that more women than ever are living a healthy life to tell their survival stories. They have not just survived, but are thriving. Let us take you through a couple of survivor stories which not just gives strength and hope, but also the immense courage to stand up and fight it. The names are, however, changed to prevent identity.

Help yourself and others too: For most women, getting diagnosed with blood cancer can mean the end of life. While for the medical person, it is just another individual, for the individual, there is an entire world to think of, her world. What will happen to her family, her job, her life in total. Each person is different, and so the approach has to be different. It should not be a routine combo of surgery, chemo, and radiation. While some hospitals do it, giving a personalized touch helps. That is what happened Susan, who had a complete set of people including dietitian and psychiatrist to help her. The change that she saw with this approach led her to give a helping hand to others. She presently helps people fight and overcome breast cancer and has an extremely fulfilling life.

Shrink the tumor, not your life: For a person with two kids, Tina was aghast when she was diagnosed with breast cancer. She was just 31, and her second daughter was just turning 1, she was extremely distraught. But, her family stood with her through those testing times when she would not have time to run with her daughter or walk along with her mother. With immense support from her family, she is now free of cancer and is a Zumba instructor and now spends quality time with her daughter.

An experiment that worked: At 46 years of age, Maya was diagnosed with stage 3 breast cancer. She found a lump in her breast, which turned out to be breast cancer. The doctor said she would need it removed, and she also opted for surgery. What worked for her, though, is the fact that she was advised to try tamoxifen, which was not so strongly recommended during the initial times. She went ahead and tried, and even after 30 years down the line, is still free of cancer.

Two lives saved: At 23, Sonia was diagnosed not just with stage 4 breast cancer, but also with pregnancy. Re-testing yielded negative results. So she went ahead with chemo and radiation, but the abdominal fullness continued, and when tested again, the tests confirmed her pregnancy. She carried it through, and delivered 4 weeks prematurely but is very healthy and cancer-free now.

Breast reduction or breast reduction surgery is a form of cosmetic surgery where the size of disproportionately large breasts is reduced.

Extra large breasts may cause neck pain, back pain and several other physical symptoms. Many women undergo a breast reduction to make life easier. This surgery provides effective results.

The procedure of breast reduction surgery-

Breast reduction surgeries can be conducted in an outpatient facility. You may have to stay for one night at a hospital as well. While performing this surgery, a patient is given general anaesthesia, which will make the patient asleep during the process.

Breast reduction surgery requires about two to five hours to be completed successfully. During the process, the surgeon will create a cut around the nipple and then on the breast. The cut is made in the shape of a keyhole. Extra skin, tissue and fat will be removed from the breast through the keyhole-shaped incision. Drainage tubes are also utilized for removal of excess skin and fat. After the removal is complete, and enough skin has been removed, the breasts are stitched. They are then wrapped in a special gauze. Sometimes, a surgical bra is required to be worn by the patient during the surgery.

Recovery from breast reduction surgery-

After a breast reduction surgery is performed, the patient must take a minimal one week off from any kind of work or school. Some women require two weeks or more to recover. However, this varies from patient to patient, but not more than three weeks are required for recovery.

You will be having a follow-up appointments with your surgeon, where the bandages and stitches on the breasts are removed.

As a part of the recovery process, a woman must abstain from all kinds of physical activities for one month following the surgery. After the surgery, it is likely for a patient to feel tired and experience breast pain. However, this is normal and you can have oral pain killers prescribed by your surgeon to get relief and ease. Heavy lifting should be strictly restricted.

Breast reduction surgery is an efficient cosmetic surgery, which enables women to reduce their breast size and volume. The results of such a surgery are quite satisfactory.

Breast Reduction - Know The Procedure and Recovery!

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.

Breast Cancer - New Advancements That Can Help!

Our spinal disk resembles a jelly donut, wherein the softer insides are protected by the hard exterior. Sometimes, as a result of some injury or an accident the jelly slips out, leading to an extremely painful condition which in medical parlance is known as herniated disc. The pain that you are subjected to, during herniated disc, occurs as the nerves nearby are damaged due to the concussion. Apart from pain, herniated disc is preceded by other symptoms, some of them are:

1. Pain in the arm or the leg
Depending on which part of the body you have suffered the herniated disc, in the neck or in your lower back, this condition is succeeded by intense pain either near the buttocks or near the shoulders. It goes without saying that this pain increases sharply with movement.

2. Numbness
That part of the body where the nerves are damaged due to herniated disc often becomes numb and has no sensation whatsoever.

3. Weakness
Due to herniated disc, the muscles become weak that considerably impairs and curbs mobility.

However, there are various ways by which you can prevent a herniated disc. Some of them are-

1. Exercise
Exercise in any form and even for a short while yields several benefits. Your body invariably gains momentum and agility. If you exercise daily, your spine becomes more stable and strong, thereby preventing a possible herniated disc.

2. Maintaining the right and good posture
A lot depends on the way you sit and walk, in fact more than you can imagine. If you sit badly, it exerts a pressure on the spine and the discs. Subsequently, a good posture does the very reverse and curbs chances of a herniated disc in the future.

3. Keep a tab on the weight
It is always healthy to maintain the right weight, the one that keeps you away from the onset of various diseases. If you are overweight, it puts more pressure on the spine disk, thereby increasing the risk of developing a herniated disc.
