Brain cancer is a disease of the brain in which cancer cells (malignant cells) arise in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of mainly non-cancerous cells are called benign tumors. Cancer cells that develop from brain tissue are called primary brain tumors while tumors that spread from other body sites to the brain are termed metastatic or secondary brain tumors.

Prologue:

Brain cancer is actually the abnormal growth and uncontrolled growth of the cancer cells in the brain,that forms a tumor in the brain.Tumours can be either benign or malignant.

Benign brain tumours are abnormal collections of cells that reproduce slowly and usually remain separate from the surrounding normal brain.

Malignant tumours reproduce and grow quickly. Their borders are hard to distinguish from the normal brain around them.

Symptoms:

There are few early symptoms of brain cancer, but as the tumour grows within the confines of the skull, it causes increased intracranial pressure and exerts pressure on the brain, causing signs to develop.

Brain cancer symptoms and signs are varied and depend on the area of the brain involved, but can include:

Headaches.

Seizures.

Nausea and vomiting, which, CANSA reports, may be worse in the morning or after a sudden position change.

Difficulty walking or clumsiness.

Vision changes.

Changes in alertness.

Behavioural impairment.

Causes:

Brain cancer occurs when there is an uncontrolled growth of cancer cells in the brain that form a malignant brain tumor. The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.

What are the risk factors for brain cancer?

Certain inherited conditions, including neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot syndrome

Personal history of cancer or family history of brain cancer

Impaired immune system

Radiation therapy of the head

Treatments Options:

Treatment

Surgery is the main form of treatment for brain tumors that lie within the membranes covering the brain or in parts of the brain that can be removed without damaging critical neurological functions. The goal is to remove the entire tumor, whenever possible, as a tumor may recur if any tumor cells are left behind. Radiation therapy and chemotherapy are generally used as secondary treatment for tumors that cannot be cured through surgery alone.

Stereotactic radiosurgery

Stereotactic radiosurgery is a treatment option that delivers a high concentration of radiation directly to the tumor in order to stop its growth, while delivering only a minimal dose of radiation to the surrounding tissue. Unlike conventional surgery, stereotactic radiosurgery does not require making an incision to remove the tumor. It can be especially effective in patients with many small metastatic brain tumors.

Brain Cancer

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?

The relationship between intelligence and brain size, both among people and between various species, has never been precisely well defined. People often believe that their outstanding psychological capacities must mean that they are superior to all animals as far as brain size is concerned. However, it is not true since whales and elephants have much bigger brains than humans and humans have the same brain-to-body mass proportion as mice do.

Here are a number of ways by which the brain size can be determined:

Encephalization remainder: Since it would be against human instinct to admit loss and defeat, researchers have created a measure to determine the brain size called the encephalization remainder. It is the proportion of actual brain mass with respect to the anticipated cerebrum mass for the animal s size (based on the suspicion that bigger animals require somewhat less brain matter with respect to their size, compared to little animals). By this metric, human beings prove to be the best, with an EQ of 7.5 outperforming the dolphin's 5.3 and the mouse's 0.5.
IQ testing: Without a solitary and evident method for measuring intelligence, some improved tests like IQ (Intelligence Quotient) are by and large acknowledged as a moderately decent working device. IQ estimations are not without issues, and there is a great deal of criticism about their significance. IQ testing uses government sanctioned tests, for example, the WAIS III (Wechsler Adult Intelligence Scale). The normal IQ is somewhere around 90 and 110. The scores beneath the normal may demonstrate changing degrees of pathology, for example, marginal intellectual function, or mental hindrance of different severity. Over the normal range is regularly connected with knowledge, splendour, talent, or genius. However, as with computers of a few eras, size and intellect do not precisely relate. Present day portable computers weighing around one or two kilogrammes can store more data and perform a greater number of assignments than supercomputers from the 1980s that used to possess expansive structures. This is a contrast amongst quantity and quality. Numerous scientists now hold the view that it is not the whole brain, which is bigger in a human with a higher IQ, yet rather certain zones that are denser and might be bigger. A fascinating late revelation is that these ranges can be expanded in size and enhanced in usefulness during the course of our life.
NeuroplasticityIt refers to the dynamic procedure of repair and maintenance that our brains are continually experiencing. We are conceived with around hundred billion neurones, yet lose around two hundred thousand a day to a procedure called pruning. As we develop and grow, pathways in the brain that are not required are detached, and the neurones pass on. However, in a compensatory procedure, new neurones are delivered and more detailed associations are built up between neurones that are more dynamic. This is the procedure of de-cluttering, in which our brains develop to work at most extreme effectiveness. If you wish to discuss about any specific problem, you can consult a Neurologist.

Brain Size - How It Is Related With Intelligence?

Dyslexia is a neurological condition which makes learning a difficult process in children. Children suffering from dyslexia find themselves incapable of reading and learning as compared to their peers. Dyslexia occurs when the brain cannot process graphic symbols. This causes difficulty in recognizing, spelling and also decoding words. The effect of this condition varies from one person to another and is most often a lifelong condition. It can also vary as a result of different ages in people. However, a slower reading level is one common characteristic that is present in all dyslexic children.

Dyslexia is a strictly neurological condition that has little to do with a person s intelligence. It can also occur as a result of genetic conditions. Early detection of the condition can help in improvement before he or she reaches adolescence. A thorough evaluation process of the child will include the following aspects IQ level, language skills, ability of word recognition, phonological processing, automaticity skills, fluency skills, family history and also knowledge of vocabulary.

The most common symptoms of dyslexia include:

Trouble reading
Very slow progression to milestones such as walking, talking, crawling and learning to ride a bicycle.
Slow development of speech
Trouble with hand-eye coordination
A slow rate of learning when it comes to data
Problem with speech
Very poor concentration span
Children suffering from dyslexia are more prone to developing certain autoimmune diseases such as eczema and asthma.
Dyslexia is sometimes subdivided into a number of categories such as Surface Dyslexia, Rapid Deficit Dyslexia, Visual Dyslexia and Phonological Dyslexia.

There is no medical treatment for dyslexia and help generally includes assigning reading specialists, child psychologist, speech-language pathologists and child neuropsychologists.

Certain practices that you yourself follow when dealing with your dyslexic child are:

Praise your child from time to time
Remind your child that being dyslexic has nothing to do with intelligence levels
Mix with other parents who have dyslexic children and interact with them about ways and strategies to heighten the child s confidence level.
Deal with your child patiently.

Understanding Dyslexia - What All Should You Know


Autism is defined as a neurobiological pervasive development disorder that includes lack of social skills and inability to reciprocate to social interactions. The patient may also have intellectual and cognitive deficits and problems in communication (verbal as well as non-verbal).

Ayurveda is the oldest study of medicine and has proved to be very effective when it comes to managing and treating those affected by autism. The earlier an autistic person resorts to ayurveda, the more effective it is.

Ayurvedic drink recipe for treating the symptoms of autism: (should be taken daily)
1.1/3 cup of yogurt
2.3/4 cup of water
3. Cumin
4. Coriander and
5. Ginger
Or
Diluted fresh pomegranate juice

Ayurveda in curbing aggression:
Autism includes heightened aggression and aversion from social interaction due to a neurological condition that impairs the functioning of the brain. Not all autistic patients are violent towards others, but may express their frustration by self-harm and emotional outbursts. One can curb these emotional outbursts by taking herbal supplements. An ayurvedic herb called brahmi (bacopa monnieri) which is known for its, anti-anxiety, neuroprotection and antioxidant properties can help considerably.

Regular massages using sandalwood, rose, lavender and gotu kola oils are also very calming and relieving, because it stimulates the blood flow and neuronal responses. Massage also helps in increasing eye contact and social relatedness, less stereotypical behavior and improved sleep.

Ayurvedic herbs for autism:
1. Brahmi- scientifically known as bacopa monnieri, brahmi is an important herb that delays the process of forgetting and improves memory. Not only does brahmi improve memory, but also increases the grasping power, intellect and speech and also corrects the abnormality of emotions, personality and mood of an autistic individual. It also helps in performing complex tasks such as comprehension, reasoning and learning.

2. Ashwagandha- scientifically known as withania somnifera, ashwagandha has high affinity for gamma aminobutyric acid (gaba) receptors. Low gaba activity is related to cognitive impairment.

3. Shankhapushpi- scientifically known as convolvulus pluricaulis, shankhapushpi is very effective in improving learning and memory and is highly effective in treating insanity and epilepsy. 

4. Centella asiatica- this ayurvedic herb is used as a medication for insanity, speech disorders and epilepsy, making it a very useful drug for treating autism.

Parkinson's disease is a neurodegenerative condition that affects your brain cells which produce dopamine and thus hampering all kinds of motor functioning and other emotional responses. After the disease is diagnosed, medication and therapy can help to provide relief from the symptoms to a large extent but a permanent cure is not possible.

Causes:

The disorder does not have a definite set of causes. A small percentage of the cases have been related to hereditary factors and others have a range of environmental causes associated with them.

1. Genetic factors:

Specific gene mutations and gene variations have been proved to cause Parkinson's, such as SNCA, PARK2, PARK7, PINK1 and LRRK2. These make or recycle proteins which are linked to the disease.

Research shows that men are at a 1.75 times greater risk of developing the condition than women are. Also, age plays a role with most cases occurring after the age of 60.

2. Environmental factors:

Regular exposure to inorganic insecticides, pesticides, herbicides and heavy metals or other toxins may cause the disorder. In rare cases, Parkinson's disease occurs in the aftermath of a severe head injury or immune disorders.

Symptoms:

The symptoms can be classified into two broad categories-

1. Motor symptoms:

The hand tremors when in resting position
The grip loosens
Walking slows down
Facial muscles freeze partially
Speech is slurred
Balance is disturbed
Swallowing is painful
Urination is abnormally frequent
Dementia-like symptoms are seen
There is involuntary twitching of the fingers and toes
Repetition of the same movement in quick succession is nearly impossible
2. Non-motor symptoms:

Dental problems
Vision impairment
Skin disorders
Panic attacks
Excessive secretion of saliva
Extreme weight loss or gain
Sexual problems
Loss of sense of smell
Lowering of the pitch of the voice
Fatigue
