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.
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. If you wish to discuss about any specific problem, you can consult a Neurosurgeon.
She is 63 years old suffering from diabetes-on Insulin+other allopathy medicines but the sugar level running from 70 to 200 and more. Today fasting 90 but PP is going high between 200 to 300. She is on Insulin from last 15 years. Can she be treated with you? And I am also suffering from Slip Disc. L4 L5 S1 and taken 15 days Ayurvedic treatment such as Katibastyi, Malish, Steam bath etc but there is nothing complete and permanent. Please advise us to permanent treatment.
For few days when seating for a long time then suddenly arise tiny pain in lower of hip the where end of spine please suggest me sir.
I am a 30 years old male and since last 3 months I was having pain in right leg whenever I used to walk. My doctor advised me Lumbosacral MRI and my findings are as under: 1. Lumbar lordosis is mildly straightened. 2. Disc desiccation noted at L5-S1 noted. 3. Posterior disco osteophytes complex seen at L5-S1 level causing canal stenosis measuring 7mm and bilateral lateral recess stenosis, causing compression upon traversing S1 nerve roots and mild foramina narrowing with abutting bilateral L5 nerve roots. 4. Mild diffuse disc bulge at L4-5 level causing indentation of thecal sac with early lateral recess stenosis, however no significant neural compression seen.
Beet juice: apart from being a nutritional powerhouse, beet juice is a great source of nitric acid. The latter helps with blood flow in the body. A smooth blood flow, on the other hand, helps the brain in functioning properly. A study has found that people who consume beet juice have an increased circulation in the white matter resulting from an increased brain activity. This juice is sweet in taste and can be consumed every alternate day.
Berry smoothies: acai is a fruit which has a south african origin and hits the top of the list when it comes to brain assisting food. It increases the flow of the blood and dilates the blood vessels. However, this is extremely expensive. Berries also have a similar effect on the brain, but they are less powerful in nature. What can be done is to mix a little ingredient of acai in frozen berries juice and drink the same every day. Frozen berries retain the freshness and the nutritional benefits. This drink will improvise your brain and increase blood flow in the body.
Pomegranate juice: pomegranate is a great antioxidant and it very aptly limits the free radicals from damaging the brain cells. Antioxidants are also credited with increased blood flow and protection of the heart. A healthy cardiovascular system is synonymous to an increased brain function. What is surprising is the fact that pomegranate has more antioxidant content compared to red wine and green tea. Pomegranate juice can be consumed daily during the morning or afternoon.
Carrot juice: carrot is known for its healthy components that are beneficial for the eyes. Recent studies have revealed that they are great for the brain too. Like other colored vegetables, they are a great source of antioxidant and have a high content of beta-carotene. Carrot juice can reduce the inflammation of the brain cells and improve memory. Carrot juice is not at all bitter and the same can be consumed every alternate day after your meal.
Cocoa: a harvard study revealed that two cups of cocoa on a daily basis greatly helps a person in improving memory. Cocoa contains flavanols that keep the blood pressure normal and relaxes the blood vessel linings. Cocoa is also known to be a great antioxidant agent that limits the free radical to affect the brain cells. Cocoa should not be overloaded with sugar and should be consumed hot before starting your day.
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.
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
- 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.
- 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. If you wish to discuss about any specific problem, you can consult a neurosurgeon.
I have small disk. And my lift leg paining I went doctor he proscribed me some pain lure and nerve medication but still my leg paining. How I can get well and don't take medication. Thanks.
Umbilical hernia diet
An umbilical or belly button hernia occurs when a part of the intestines or the abdominal lining protrudes through an opening in the abdominal muscles. The protruding intestines may get squeezed or strangulated resulting in the blood supply getting cut off. Surgery may be required in serious cases of umbilical hernia. Doctors often suggest a special diet for umbilical hernia patients as this helps to prevent further complications.
Foods to avoid
Certain foods are not recommended for people with an umbilical hernia and should be avoided.
White refined flour foods made from white refined flour have a low fiber content. Eating these foods may cause constipation and should therefore be avoided. This is because constipation causes straining of the abdominal muscles during bowel movements and may cause further protrusion of the intestines through the abdominal muscles in the region of the belly button.
Low fiber fruits and vegetables the low fiber content in these foods can also lead to constipation. Examples of fruits and vegetables with low fiber content include skinless raw fruits, cooked fruits, and canned or cooked vegetables without seeds, hulls or skin.
Fatty foods foods with a high fat content should be avoided. This is because obesity results in greater pressure on the abdominal muscles and can increase the risk of umbilical hernia. Examples of foods with a high fat content include fatty meat such as pork, whole milk, butter, cream, margarine and fried foods.
Sugar limit your calorie intake by cutting down on foods such as pastries, cakes, chocolates and soda pop. Limiting your sugar intake will also help you to lose some weight, taking pressure off your abdominal region.
Foods to include
A special diet is required after umbilical hernia surgery. This will help you to minimize your convalescence time. The special dietary requirements include:
Fruits fresh fruits that have high fiber content and are rich in antioxidants should form a part of every meal. The high fiber content will ensure that you do not get constipated and the antioxidants will help protect your body and boost your immune system. Try to eat different types of fruits so as to get adequate amounts of different vitamins. Citrus fruits, berries, and apples are some examples of fruits with a high fiber and vitamin content.
Vegetables these too have a high fiber content that will guard against the dangers of constipation after an umbilical hernia surgery. They also have high levels of vitamins and minerals and should also be included with every meal.
Lean meat meat is a source of protein, which is essential to the repair of damaged tissue. Lean meat like poultry and fish is an excellent source of low fat protein. Have one good source of low fat protein with every meal.
Low fat dairy products these are a good source of protein and can be alternated with lean meats to provide your body with sufficient protein.
High fiber breakfast foods will aid digestion and so your breakfast should consist of foods made from whole wheat flour, wheat germ, oatmeal, or bran.

Are you experiencing excessive uterine bleeding? Excessive uterine bleeding may occur between a woman’s periods or before the periods, after having sex, or due to the development of spotting or bleeding after attaining menopause. Any menstrual cycle, which lasts longer than 21–35 days is called excessive, and this is an abnormal form of uterine bleeding.
Causes of Excessive Uterine Bleeding:
The various causes of excessive uterine bleeding are as follows:
One of the main causes is hormonal imbalance, as the balance between estrogen and progesterone gets disrupted. This balance is required for the regulation and development of the lining of endometrium or uterus lining. Because of the hormonal imbalance, the endometrium develops excessively causing heavy bleeding.
Uterine fibroids, which are non cancerous tumours, may lead to prolonged and excessive uterine bleeding.
Polyps are small benign developments on the uterus lining which cause heavy bleeding. They occur because of high levels of hormones.
Adenomyosis is a condition which develops when the endometrium glands get embedded in the uterine muscle, leading to excessive uterine bleeding.
Using intrauterine devices or IUDs may cause side effects as well.
Several uterine cancers, ovarian cancers and cervical conditions may be responsible as well. Inherited bleeding disorders such as von Willebrand’s disease is another likely cause.
Several medicines and drugs, including NSAIDs and anticoagulants are a common cause.
There are different ways of treating excessive uterine bleeding, depending upon the cause of bleeding and the patient’s age.
Medications: Several medicines are used for the treatment of abnormal uterine bleeding. Hormonal medicines and birth control pills are used to improve the regularity of periods. Non steroidal anti-inflammatory drugs are also used to manage excessive uterine bleeding. Several antibiotics are also used.
Surgery: In many cases, a woman has to undergo a surgery for the removal of polyps and fibroids, which cause excessive bleeding. Certain fibroids are removed via hysteroscopy and other techniques for treatment are used as well. Endometrial ablation can be carried out to manage the bleeding. This treatment aims at permanent reduction of the excess bleeding. Hysterectomy has to be carried out when other treatments are unsuccessful. This is a serious surgery and after it, a woman will no longer have periods, and she will not be able to conceive a child.
In case of excessive uterine bleeding, you must consult a doctor as soon as possible. This will enable early treatment and prevent the development of further complications.

Breast Cancer Prevention:
Anything that increases your chance of developing cancer is called a cancer risk factor; anything that decreases your chance of developing cancer is called a cancer protective factor.
Some risk factors for cancer can be avoided, but many cannot. For example, both smoking and inheriting certain genes are risk factors for some types of cancer, but only smoking can be avoided. Regular exercise and a healthy diet may be protective factors for some types of cancer. Avoiding risk factors and increasing protective factors may lower your risk but it does not mean that you will not get cancer. Different ways to prevent cancer are being studied, including:
Changing lifestyle or eating habits. Avoiding things known to cause cancer. Taking medicine to treat a precancerous condition or to keep cancer from starting.
General information about breast cancer:
Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. Breast cancer is the second most common type of cancer in india
Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast.
The breast is made up of lobes and ducts. Each breast has 15 to 20 sections called lobes, which have many smaller sections called lobules. Lobules end in dozens of tiny bulbs that can make milk. The lobes, lobules, and bulbs are linked by thin tubes called ducts.
Enlarge Drawing of female breast anatomy showing the lymph nodes, nipple, areola, chest wall, ribs, muscle, fatty tissue, lobe, ducts, and lobules.
Anatomy of the female breast. The nipple and areola are shown on the outside of the breast. The lymph nodes, lobes, lobules, ducts, and other parts of the inside of the breast are also shown.
Each breast also has blood vessels and lymph vessels. The lymph vessels carry an almost colorless fluid called lymph. Lymph vessels lead to organs called lymph nodes. Lymph nodes are small bean-shaped structures that are found throughout the body. They filter lymph and store white blood cells that help fight infection and disease. Clusters of lymph nodes are found near the breast in the axilla (under the arm), above the collarbone, and in the chest.
Avoiding risk factors and increasing protective factors may help prevent cancer. The following are risk factors for breast cancer:
Older agea personal history of breast cancer or benign (noncancer) breast diseasea family history of breast cancerinherited gene changesdense breasts
Exposure of breast tissue to estrogen made in the bodytaking hormone therapy for symptoms of menopause radiation therapy
The following are protective factors for breast cancer:
Less exposure of breast tissue to estrogen made by the bodytaking estrogen-only hormone therapy after hysterectomy,
Estrogen-only hormone therapy after hysterectomyselective estrogen receptor modulatorsaromatase inhibitors and inactivators
Risk-reducing mastectomy ovarian ablationgetting enough exercise
It is not clear whether the following affect the risk of breast cancer:
Factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk
Older age is the main risk factor for most cancers. The chance of getting cancer increases as you get older.
A personal history of breast cancer or benign (noncancer) breast disease
Women with any of the following have an increased risk of breast cancer:
A personal history of invasive breast cancer, ductal carcinoma in situ (dcis), or lobular carcinoma in situ (lcis). A personal history of benign (noncancer) breast disease.
A family history of breast cancer
Women with a family history of breast cancer in a first-degree relative (mother, sister, or daughter) have an increased risk of breast cancer.
Inherited gene changes:
Women who have inherited changes in the brca1 and brca2 genes or in certain other genes have a higher risk of breast cancer, ovarian cancer, and maybe colon cancer. The risk of breast cancer caused by inherited gene changes depends on the type of gene mutation, family history of cancer, and other factors.
Men who have inherited certain changes in the brca2 gene have a higher risk of breast, prostate, and pancreatic cancers, and lymphoma.
Having breast tissue that is dense on a mammogram is a factor in breast cancer risk. The level of risk depends on how dense the breast tissue is. Women with very dense breasts have a higher risk of breast cancer than women with low breast density.
Increased breast density is often an inherited trait, but it may also occur in women who have not had children, have a first pregnancy late in life, take postmenopausal hormones, or drink alcohol.
Exposure of breast tissue to estrogen made in the body
Estrogen is a hormone made by the body. It helps the body develop and maintain female sex characteristics. Being exposed to estrogen over a long time may increase the risk of breast cancer. Estrogen levels are highest during the years a woman is menstruating.
A woman's exposure to estrogen is increased in the following ways:
Early menstruation: beginning to have menstrual periods at age 11 or younger increases the number of years the breast tissue is exposed to estrogen. Starting menopause at a later age: the more years a woman menstruates, the longer her breast tissue is exposed to estrogen. Older age at first birth or never having given birth: because estrogen levels are lower during pregnancy, breast tissue is exposed to more estrogen in women who become pregnant for the first time after age 35 or who never become pregnant.
Taking hormone therapy for symptoms of menopause:
Hormones, such as estrogen and progesterone, can be made into a pill form in a laboratory. Estrogen, progestin, or both may be given to replace the estrogen no longer made by the ovaries in postmenopausal women or women who have had their ovaries removed. This is called hormone replacement therapy (hrt) or hormone therapy (ht). Combination hrt/ht is estrogen combined with progestin. This type of hrt/ht increases the risk of breast cancer. Studies show that when women stop taking estrogen combined with progestin, the risk of breast cancer decreases.
Radiation therapy to the breast or chest:
Radiation therapy to the chest for the treatment of cancer increases the risk of breast cancer, starting 10 years after treatment. The risk of breast cancer depends on the dose of radiation and the age at which it is given. The risk is highest if radiation treatment was used during puberty, when breasts are forming.
Radiation therapy to treat cancer in one breast does not appear to increase the risk of cancer in the other breast.
For women who have inherited changes in the brca1 and brca2 genes, exposure to radiation, such as that from chest x-rays, may further increase the risk of breast cancer, especially in women who were x-rayed before 20 years of age.
Obesity increases the risk of breast cancer, especially in postmenopausal women who have not used hormone replacement therapy.
Drinking alcohol increases the risk of breast cancer. The level of risk rises as the amount of alcohol consumed rises.
The following are protective factors for breast cancer:
Less exposure of breast tissue to estrogen made by the body
Decreasing the length of time a woman's breast tissue is exposed to estrogen may help prevent breast cancer. Exposure to estrogen is reduced in the following ways:
Early pregnancy: estrogen levels are lower during pregnancy. Women who have a full-term pregnancy before age 20 have a lower risk of breast cancer than women who have not had children or who give birth to their first child after age 35. Breast-feeding: estrogen levels may remain lower while a woman is breast-feeding. Women who breastfed have a lower risk of breast cancer than women who have had children but did not breastfeed.
Taking estrogen-only hormone therapy after hysterectomy, selective estrogen receptor modulators, or aromatase inhibitors and inactivators
Estrogen-only hormone therapy after hysterectomy
Hormone therapy with estrogen only may be given to women who have had a hysterectomy. In these women, estrogen-only therapy after menopause may decrease the risk of breast cancer. There is an increased risk of stroke and heart and blood vessel disease in postmenopausal women who take estrogen after a hysterectomy.
Selective estrogen receptor modulators:
Tamoxifen and raloxifene belong to the family of drugs called selective estrogen receptor modulators (serms). Serms act like estrogen on some tissues in the body, but block the effect of estrogen on other tissues.
Treatment with tamoxifen lowers the risk of estrogen receptor-positive (er-positive) breast cancer and ductal carcinoma in situ in premenopausal and postmenopausal women at high risk. Treatment with raloxifene also lowers the risk of breast cancer in postmenopausal women. With either drug, the reduced risk lasts for several years or longer after treatment is stopped. Lower rates of broken bones have been noted in patients taking raloxifene.
Taking tamoxifen increases the risk of hot flashes, endometrial cancer, stroke, cataracts, and blood clots (especially in the lungs and legs). The risk of having these problems increases with age. Women younger than 50 years who have a high risk of breast cancer may benefit the most from taking tamoxifen. The risk of having these problems decreases after tamoxifen is stopped.
Taking raloxifene increases the risk of blood clots in the lungs and legs, but does not appear to increase the risk of endometrial cancer. In postmenopausal women with osteoporosis (decreased bone density), raloxifene lowers the risk of breast cancer for women who have a high or low risk of breast cancer. It is not known if raloxifene would have the same effect in women who do not have osteoporosis. Talk with your doctor about the risks and benefits of taking this drug.
Aromatase inhibitors and inactivators:
Aromatase inhibitors (anastrozole, letrozole) and inactivators (exemestane) lower the risk of a new breast cancer in women who have a history of breast cancer. Aromatase inhibitors also decrease the risk of breast cancer in women with the following conditions:
Postmenopausal women with a personal history of breast cancer. Women with no personal history of breast cancer who are 60 years and older, have a history of ductal carcinoma in situ with mastectomy, or have a high risk of breast cancer based on the gail model tool (a tool used to estimate the risk of breast cancer).
In women with an increased risk of breast cancer, taking aromatase inhibitors decreases the amount of estrogen made by the body. Before menopause, estrogen is made by the ovaries and other tissues in a woman's body, including the brain, fat tissue, and skin. After menopause, the ovaries stop making estrogen, but the other tissues do not. Aromatase inhibitors block the action of an enzyme called aromatase, which is used to make all of the body's estrogen. Aromatase inactivators stop the enzyme from working.
Possible harms from taking aromatase inhibitors include muscle and joint pain, osteoporosis, hot flashes, and feeling very tired.
Some women who have a high risk of breast cancer may choose to have a risk-reducing mastectomy (the removal of both breasts when there are no signs of cancer). The risk of breast cancer is much lower in these women and most feel less anxious about their risk of breast cancer. However, it is very important to have a cancer risk assessment and counseling about the different ways to prevent breast cancer before making this decision.
The ovaries make most of the estrogen that is made by the body. Treatments that stop or lower the amount of estrogen made by the ovaries include surgery to remove the ovaries, radiation therapy, or taking certain drugs. This is called ovarian ablation.
Premenopausal women who have a high risk of breast cancer due to certain changes in the brca1 and brca2 genes may choose to have a risk-reducing oophorectomy (the removal of both ovaries when there are no signs of cancer). This decreases the amount of estrogen made by the body and lowers the risk of breast cancer. Risk-reducing oophorectomy also lowers the risk of breast cancer in normal premenopausal women and in women with an increased risk of breast cancer due to radiation to the chest. However, it is very important to have a cancer risk assessment and counseling before making this decision. The sudden drop in estrogen levels may cause the symptoms of menopause to begin. These include hot flashes, trouble sleeping, anxiety, and depression. Long-term effects include decreased sex drive, vaginal dryness, and decreased bone density.
Getting enough exercise:
Women who exercise four or more hours a week have a lower risk of breast cancer. The effect of exercise on breast cancer risk may be greatest in premenopausal women who have normal or low body weight.
It is not clear whether the following affect the risk of breast cancer:
Certain oral contraceptives contain estrogen. Some studies have shown that taking oral contraceptives (" the pill") may slightly increase the risk of breast cancer in current users. This risk decreases over time. Other studies have not shown an increased risk of breast cancer in women who take oral contraceptives.
Progestin -only contraceptives that are injected or implanted do not appear to increase the risk of breast cancer. More studies are needed to know whether progestin-only oral contraceptives increase the risk of breast cancer.
Studies have not proven that being exposed to certain substances in the environment, such as chemicals, increases the risk of breast cancer.
Studies have shown that some factors do not affect the risk of breast cancer.
The following do not affect the risk of breast cancer:
Having an abortion. Making diet changes such as eating less fat or more fruits and vegetables. Taking vitamins, including fenretinide (a type of vitamin a). Cigarette smoking, both active and passive (inhaling secondhand smoke). Using underarm deodorant or antiperspirant. Taking statins (cholesterol -lowering drugs). Taking bisphosphonates (drugs used to treat osteoporosis and hypercalcemia) by mouth or by intravenous infusion.
Cancer prevention clinical trials are used to study ways to prevent cancer.
