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?

Of all cancer types that affect the female population, breast cancer is the most common one. Statistics show that above 1 in 8 women in the USA are likely to develop breast cancer (invasive type, which is often severe). Changing lifestyles including prolonged use of birth control, smoking, alcohol abuse, lack of physical activity, dietary changes, etc., have led to an increased incidence. As these are here to stay, the only way is to prevent.

The likelihood of developing breast cancer is determined by risk factors. Some of these risk factors cannot be changed. For instance, age, ethnicity, and history of familial breast cancer. However, there are others, which can be acted upon or modified to reduce the chances of developing breast cancer. 

Some of the preventable risk factors are as follows:

Nicotine abuse: Quitting smoking has multiple benefits for a woman, and one major benefit is the reduced risk of developing breast cancer. Other benefits include reduced incidence of diabetes, heart disease, and other cancers.
Hormone replacement therapy: To the extent possible, avoid prolonged use of birth control pills or hormones for other treatment purposes. In addition to using non-hormonal methods, if not avoidable, constantly monitoring hormone levels is very important. Birth control pills should especially be avoided by women over 35 years of age who smoke. The risk associated with developing cancer reduces as soon as the hormone supplement is stopped.
Weight Management: One of the major risk factors is obesity, and in people with other non-alterable risk factors, it is best to work on weight management from an early age. Talk to your doctor about your ideal BMI and ensure this is maintained.
Physical Activity: Regular physical activity, at least 30 minutes per day, in addition to strength training will help in keeping the body agile and managing weight. It also reduces the risk of breast cancer.
Breastfeeding: Studies have shown that breastfeeding has protective effect against breast cancer; longer a baby is breast fed, greater is the protective benefit.
Screening: Even if not completely preventable, early detection of breast cancer is very important. This will help in less severe treatment and better prognosis. Recommended ages for mammography are as follows: 
In the age of 40 to 44, an annual mammogram is advised along with a discussion with the doctor on the risks.
An annual mammogram for all women in the age of 45   54 is important as most women enter menopause by this time. This needs to be continued annually, as self-breast exams alone cannot detect cancer, thus it is a good practice and anything abnormal will not go undetected.
These will help reduce the risk of developing breast cancer, help in early detection, and improve prognosis.

Breast Cancer - 6 Ways You Can Reduce The Risk!

Q1. What exactly is Laparoscopy?
Laparoscopy is an alternative to 'Open' surgery wherein the abdomen is opened by tiny 'key hole' incisions and surgery is done. 'Scopy' means the use of an endoscope or telescope to see inside the abdomen. This is attached to a camera and a light source and the inside of the abdomen is projected on to a monitor. The surgeon performs surgery looking at this screen. The surgeon makes a total of 2-4 small cuts on the abdomen ranging from half to 1 cm through which the telescope and other thin surgical instruments are passed into the abdomen. When the uterus is removed , known as hysterectomy, there is also a cut at the top of the vagina where the uterus is attached.
Q2. What kind of gynaecological surgeries can be performed by Laparoscopy?
Most surgeries done in gynaecology can now be performed by Laparoscopy and do not require the large incision as for open surgery. Laparoscopy can be done sometimes only for diagnosis and is called Diagnostic Laparoscopy, as in checking whether the tubes are open or not and to look for any causes of infertility or pain outside the uterus. In women who are unable to conceive, Diagnostic Laparoscopy is often combined with Hysteroscopy (endoscope inside the uterus, inserted from below, via the vagina). When laparoscopy is done to perform some surgical procedure inside the abdomen it is called Operative Laparoscopy. This may be for simple procedures like sterilization, minor adhesions, drilling ovaries; or for intermediate or major reasons like fibroids, endometriosis, removal of ovaries or tubes or both or removal of uterus, for staging of cancers or radical surgeries for cancer. However, about 5% of all surgeries including those for cancer or very large tumours may benefit from open surgery.
Q3. Why does an expert surgeon recommend Laparoscopy over Open Surgery?
Laparoscopic surgery has many advantages above open surgery: the incisions are much smaller (open surgery incisions are 8-10 cms long), therefore pain is much less; requirement for pain killers (which can have side-effects like sleepiness, impaired judgement) is lesser; hospital stay is shorter; complications fewer; requirement for blood transfusions infrequent; recovery in terms of physical, emotional and mental state is much better and quicker; return to work is faster with consequent lesser loss of working and earning days. Surgery with laparoscope is more precise because it is magnified view. Further vision is much better because it's like having your eye behind the structure because you can see with the telescope at places where the surgeon's eye cannot reach.
Q4. If the cuts on the abdomen are so small in Laparoscopic surgery, how do you remove the uterus or a large tumour from inside the abdomen?
Quite often if the tumour is not malignant and contains fluid, it is punctured to collapse it into a smaller size. If it is solid, it can be cut into smaller pieces inside the abdomen using a special instrument. The collapsed or cut structures can be removed gently through the 1 cm cut on the abdomen which may be increased a bit if required. After hysterectomy, the uterus can be removed easily from below, through the vagina.
Q5. Will there be much pain or discomfort after Laparoscopic Surgery?
There may be some pain and discomfort in lower abdomen for one day to few days after Laparoscopic surgery but this is much less as compared to open surgery because the incisions on the abdomen are much smaller and there is much less tissue handling inside the abdomen by fine instruments instead of rough, big, gloved hands which can cause tissue injury in open surgery. There may be some pain in the shoulder following laparoscopy. This is not serious and is due to the gas used in the surgery to make space for instruments.
Q6. When can I be discharged from hospital?
Following Diagnostic Laparoscopy or with simple Operative Laparoscopy you can expect to be discharged from hospital latest by the morning after surgery. In most other cases of intermediate or even major surgery, discharge is generally 1-2 days following the surgery unless there is some health issues prior to the surgery or any complication during the surgery. The complication rates for Laparoscopic surgery are not more than for open surgery and depend upon patient factors like anaemia, diabetes, obesity and skill of the surgeon.
Q7. When can I perform routine household activities or return to work after Laparoscopic Surgery?
Recovery after surgery depends upon many factors: presence of health problems before surgery; why the surgery is required; what surgery is being done; problems or complications of surgery, anaesthesia or blood transfusions. If all is well, one can perform routine household activities by 1 week, provided one doesn't feel tired. Although there may not be any harm, it may be unwise to be normally active within 48 hours of procedure. Following Diagnostic Laparoscopy or Operative Laparoscopy for simple procedures, one can return to work in 1 week. For other procedures, a 2-3 week off from work is reasonable. It depends on the type of work you are returning to. Avoid too rapid return to work if it is manually hard or requires standing for long durations of time. Sometimes a surgical procedure brings on a well needed rest and break from a lifetime of work. Mostly, when you return to work depends upon your own body and its signals of tiredness. You need to listen to those signals.


Know All About Gynae Laparoscopy Surgery

A broken bone or a fracture can be painful and it requires medical attention for the fracture to heal properly. Proper healing is necessary for the right alignment of the bone. A doctor chooses to either reduce or set the bone in terms of new alignment. The bone reduction can happen manually or surgically depending on the severity of the injury. A Surgical procedure known as the open reduction internal fixation is performed for serious fractures. It ensures that the all the broken pieces are fixed together and the injury can heal properly.
Post the fracture, the bone need to be immobilised for proper healing. This is generally achieved by imposing a cast. For fractures that are not severe in nature, a doctor might choose to impose a temporary cast so that simple motion can happen around the site of the injury. For serious fractures, a permanent cast is placed around the injury site. In the case of a shoulder injury, a patient is required to wear a sling so that the bones are immobilised.


Time Duration of a Therapy Session:
While the exact duration of physiotherapy can vary from individual to individual, it takes a minimum of 2-8 weeks for the fracture to completely heal. Certain fractures take more time to heal. The rate of healing also depends on the severity of the injury, pain threshold level of the patient, extent of work with the physiotherapist, the robustness of the physiotherapy program, extent of the injury of the soft tissue and certain other factors. Typically shoulder and neck injuries heal quicker than a fracture of the legs. The time duration of fracture healing also depends on the type of bone that has been affected.


Physiotherapy in a Hospital:
If the fracture happens in the ankle or leg, a physiotherapist might have to intervene in the hospital in order to teach patient about using assistive devices such as crutches and cane. Things that are taught during this time include using the device in order to climb stairs, right walking posture, getting into a car, taking the device off while sitting and such other techniques.


Physiotherapy at Home:
Physiotherapy can also happen from home if the doctor specifically instructs to do the same. This is typically done for people where the condition is too serious to go outside and get the physiotherapy done. Certain weight bearing restrictions are imposed around this time. The training remains the same as in the case with a hospital.


In the Clinic:
Once the patient becomes mobile enough, a doctor might suggest a patient go to a clinic to get the physiotherapy done. A physiotherapist evaluates certain things such as pain, range of motion, gait, flexibility etc. of the patient before suggesting a certain exercise plan. 




How Long Do You Need Physiotherapy Post-Fractures?

Herniated disc, bulged disc, protruded intervertebral disc (PIVD) are the different names of one condition. This is a condition where- disc in between the two vertebral bodies starts peeping out on one side- anterior or posterior. These discs are just like the bags filled with liquid material, which work like shock-absorbent. There are several hard bony vertebrae in the vertebral column and there is plenty of movements with these vertebrae. When we look on one side to other side, we look upwards, downwards or we twist and even we bend forward or backward in each and every condition, there will be a movement in these bones, these discs decide the free movements of the spine. Along with this- when we walk or run there will be shocks and jerks to all these bones and these bags decide that there won't be any kind of jerks in between the bones. So, these discs are of multiple uses.

Our spine is inverted  S  shaped. There are two main curvatures in the spine which are free to move- Cervical and Lumbar curvatures. These curvatures of the spine are maintained due to the spaces in between the two vertebrae. Whenever there is a loss or change (specially reduction) of this space between two vertebrae- pressure will be exerted on the intervertebral discs. This uneven pressure on the disc causes- protrusion/bulge/herniation of the disc- this is the condition known as SLIPPED DISC, in layman language. Why does disc slip

Generally, slipped disc condition is diagnosed by its signs and symptoms. When slipped disc starts exerting pressure on the nerves surround the disc- the nerve will be excited which gives the sensation of- Pain, Burning or Numbness in the related area of the nerve. This sensation can travel long far away to the areas, which are being supplied by the nerve and can be limited to a particular location in neck or back even. Sign & Symptoms of Slipped Disc.

Ayurveda about Slipped Disc

Where modern medical (Surgical) sciences believes that this is a problem of just bones and joints of the vertebral disc besides this Ayurveda takes a  Wholistic  (Complete and wholesome) approach towards this and tells that this is a problem at three levels-

Mamsa Dhatu, Asthi Dhatu, Majja Dhatu!!
These are different tissue levels according to Ayurveda- Mamsa is muscles, Asthi represents bones and the Majja denotes everything which is in between and in the bones.
Mamsa (the muscles) starts stiffening due to the dryness   improper diet and imbalanced lifestyle and deteriorate the curvature of the spine- which leads to the deterioration of the intervertebral discs.
Asthi (the bony tissue) is affected due to the muscles.
Majja (the disc and the neural tissue- spine) is compressed due to the pressure and all effects.
So, we need to treat the condition, wisely and in a wholesome manner, rather just to removal of the protruded tissues (Laminotomy) and this is the basic reason- there are risks associated with the surgery of the spine and in almost more than 45% cases patients had to go for a second surgery to stay pain free. Why Surgery for spine doesn t succeed. Secondly, this is a mechanical problem so medicines alone can give you temporary relief rather than the cure-  So better you save your money and invest it on complete cure for the problem, rather than just taking the pain killers and medicines which were indicated in epilepsy to just reduce the signs and symptoms.



Slipped Disc - How Can Ayurveda Avert It?

Even though brain aneurysms are becoming common these days, not all of them are required to be treated. In some cases, the physician may choose to observe an aneurysm closely before adopting any treatment measure. But in patients in whom an aneurysm has progressed to a severe level, there are two treatment options:

Open surgical clipping
Endovascular therapy or coiling
Open surgical clipping for brain aneurysms:
This procedure is typically performed by a neurosurgeon who makes an incision in the head. An opening in the bone is made, and then a clip is positioned by dissecting through the spaces of the brain. This aids in preventing the flow of blood into an aneurysm. In this procedure, the patient is required to stay in the hospital for two to three nights after which he or she is discharged.

Considerable modifications have been made in the open surgery techniques in the recent years. Neurosurgeons are now able to perform eye brow incisions or mini craniotomies for clipping an aneurysm. In these procedures, a small incision is cut out in the skin above the eyebrow for making a window. A tiny clip is placed across the mouth of an aneurysm to help it heal. But it is worthy of mention here that these are all invasive procedures and take relatively longer time to recover compared to the coiling process.

Endovascular coiling:

This treatment is also performed by a neurosurgeon, and it has been proved that this process is exceptionally suitable for patients with a ruptured aneurysm. Endovascular coiling is often done in coalesce with an angiogram, where a catheter is inserted into the vessel over the hip, which is then gradually carried to the vessels of the brain and finally to an aneurysm.
Then the coils are packed to the point where it rises from the blood vessel, which prevents the blood from flowing intothe blood vessel. Most patients undergoing this minimally invasive procedure can go home the day following the surgery. The success rate of this process is very high, and over 125,000 patients have been treated all across the globe with the help of detachable platinum coils.
Over the last few years, a substantial amount of advancements have taken place in the endovascular techniques. Recent developments show the use of flow diverting embolization devices, which are similar to a stent and are placed in the primary vessel, adjacent to an aneurysm. It diverts the flow away from an aneurysm and therefore, allows the neurosurgeons to treat the brain aneurysms, which were previously considered inaccessible and untreatable.
Both the procedures are quite efficient in treating a brain aneurysm. The most suitable option is dependent on a host of factors such as size, shape, location and overall health condition of the patient.
