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?

June is known as the Brain Tumour Month worldwide. It s worthwhile to raise public awareness and educate people about brain tumour, a disease which, though is rare is but can be really deadly. More than 500 new cases are diagnosed with brain tumour every day worldwide. The number of patients with secondary tumours are even higher than 500. However, it is common across all ages.  A primary brain tumour is a tumour that begins in the brain. It can be either malignant, which means it contains cancer cells or benign i.e. does not contain cancer cells. A secondary or metastatic brain tumour is usually cancerous. It starts elsewhere in the body and sends cancerous cells which grow in the brain.

Here are a few facts that each one of us should know about this dangerous disease

Brain tumours can occur at any age.
We don t know what causes brain tumors. Family history and high dose radiation like X-rays increases your risk.
Doctors group brain tumors by grade which means the way the brain cells look under a microscope. A higher grade number means the cells appear more abnormal and the more aggressively the tumour usually behaves.
Brain tumors are graded as grade I, grade II, or grade III, or grade IV.
Symptoms
The symptoms of brain tumour depend on the size, type, and location of the brain tumour. Some common symptoms which should not be ignored are-

Headaches
Seizures
Problems with vision
Vomiting
Mental and personality changes
Balance problems and trouble walking
Problems in speaking
Diagnosis
Brain tumours are diagnosed by the doctor based on the medical history and physical examination along with a slew of specialized tests of the brain and nervous system.

Treatment

Surgery
Radiation therapy
Chemotherapy
Anti-seizure medicines
Steroids
Ventricular peritoneal shunt
Combination of treatments
How can you safeguard yourself?
The primary tool to prevent brain tumours is by controlling your lifestyle. This means eating healthy, exercising, avoiding known carcinogens in your environment, and reducing stress.

Sleep: Sleep is a friend for brain health. An adequate amount of rest with eyes shut keeps your brain health.
Frankincense oil: Along with yoga, meditation, and breathing exercises to reduce stress, inhaling frankincense oil can help alleviate inflammation in the brain.
Anti cancer diet: Consuming a diet rich in cancer-fighting nutrients like antioxidants is critical in preventing brain tumors.
Ketogenic diet: A ketogenic diet is a high protein diet. It reduces oxidative stress and inflammation in the brain which is associated with brain tumours. It also shuts down the nutrient supply to tumors.
Calorie restriction: Dietary restriction, especially fasting has anti-carcinogenic properties just as the ketogenic diet.
Limit exposure to mobile phones: Cell phones use increases risk for brain tumours. So restriction prevents these tumours.

World Brain Tumor Day - 6 Tips To Help You Prevent Yourself Against It!

Your mother has often yelled at you for playing video games for long hours, but obviously you haven t paid heed to it. Such is the obsession with video games that they don t let you rest unless you have championed all the levels in the virtual interface. Here is the source of all problems. Studies have revealed that video games have a direct relation to neuropsychiatric problems. As a result, many health experts across the world consider video game as a kind of health abuse.

People who play action-oriented video games are at higher risks. The more you indulge in these kinds of games, the more they are going to affect the hippocampus section of your brain. It is that part of the brain which is considered to be the centre of your nervous system, memory and emotion. Reduced hippocampus volume may make person vulnerable to multiple neuropsychiatric complications. Let us see some of the signs, which may indicate the onset of certain complications arising from an over indulgence in these games.

1. You spend hours on the computer or related gaming devices and devote lesser hours for your family and friends

2. You get agitated when someone stops you midway through the game

3. You become socially isolated and show signs of occasional mood swings

4. You are unable to keep a track of time once you start playing

5. You repeatedly neglect your studies, resulting in a dip in performance at school

Why does this happen?

All of the above signs indicate that sooner or later you might develop neurological problems. When you spend an excessive number of hours on playing and navigating through the games, the  hippocampus  portion of your brain shows signs of decreased gray matter. As a result, the volume of the hippocampus shrinks, causing severe nerve related disorders such as schizophrenia, Alzheimer s disease, dementia, depression, and overall general stress.

One of the biggest reasons behind this is a lack of self-control. Most of the video games will encourage you to steal cars, run away after a theft and kill your enemies. Moreover, if you succeed, you are rewarded. This naturally unleashes a blatant urge for the gratification of all these awkward desires in your real life too. Hence, once you are encountered with the reality, you tend to show violent behavior.

Can Ayurveda Treat Cancer?

The development of abnormal cells that can spread to other areas of the body is known as cancer. It has about 100 types and includes cancer of the skin, lung, prostate gland and so on. Compared to normal body cells that follow a proper path of cell division, growth, and termination, cancer cells don't die but continue to develop and divide.

Holistic treatment of cancer involves purification and strengthening of body's immune system.

Ayurvedic treatment of cancer comprises an all-around approach keeping in mind your temperament and body characteristics, the affected energies in the body as well as the tissues involved. More importantly, the treatment focuses not only on the malignant spot but your entire body system. This is because Ayurveda believes in restoring harmony to your entire being for the ailment to be treated effectively so as to prevent its recurrence.

The treatment plan involves the purification of the body and of the toxins that influence the cells to attack your body. Certain blood cleansing herbs are administered alongside the recommendation of a detoxifying diet. To stimulate blood flow in your body, herbs that improve blood circulation are prescribed by a practitioner. This renders an efficient removal of toxins, prevents stagnant blood from forming and assists in the healing process of your tissues. Since it's a debilitating disease, herbs and minerals that boost your immunity are also suggested.

What are the holistic methods of treating cancer according to Ayurveda?

The treatment methods for cancer include:

- Elimination of toxins from the body through Panchakarma (a therapy that involves five cleansing procedures)
- Abstinence from lifestyle and foods that lead to the imbalance of the tridosha namely, vata (air), pitta (heat) and kapha (water and earth forces)
- Restitution of the functions of your digestive system
- Rejuvenation through a special form of treatment called rasayanas
- Recommendations on Ayurvedic preparations that can be taken along with radiotherapy or chemotherapy
- Suggestions on Ayurvedic medications for minimizing the side effects of the various cancer therapies

In addition to these, treatment also involves suggesting ways to relax the mind. Yoga, meditation, and praanayam (an ancient practice involving ways to control your breath) are some of the ways that are recommended for bringing about deep personal healing for cancer patients.

Can Ayurveda Treat Cancer?

Acoustic neuroma is the development of noncancerous and slow-growing tumors on the main, vestibular nerve that travels from the inner ear to the brain, connecting the two organs. They are also known as vestibular schwannoma, as it arises from Schwann cells covering the vestibular nerve. It rarely grows rapidly or attains a large enough size that can press against the brain and interfere with the vital functions of the brain. Since the tumor is benign, the patient can be assured that it won t spread to the other parts of the body; however, they can grow large enough to disrupt the normal function of the body.

The pressure from the acoustic neuroma on the main nerve can cause loss of hearing, a constant ringing in the ear and unsteadiness. As per a report published by the Acoustic Neuroma Association, 1 out of every 50,000 people suffers from this condition.

Risk factors for acoustic neuroma
Acoustic neuroma does not have quite as many risk factors. The only established risk factor for acoustic neuroma is having a parent who suffers from the rare genetic disorder neurofibromatosis 2 (NF2). However, having said that, neurofibromatosis 2 (NF2) accounts for only 5 percent of the reported cases. In most of the cases, it has been found that the tumors appear spontaneously without any indication of a family member having this disease or any medical history of the same.

The development of noncancerous tumors on the ear nerves as well as other nerves in the body is scientifically supported as a characteristic indication of neurofibromatosis 2 (NF2). Neurofibromatosis 2 (NF2) is also termed as an autosomal dominant disorder, which indicates that the mutated gene can pass from just one parent. Each of the children has a fifty-fifty chance of inheriting the disease.

However, scientists and doctors have failed to identify why specific people get these tumors. They have reached a generic conclusion about the risk factors, which may include:

Loud noises near the ear.
A parathyroid neuroma, which is a similar benign tumor of the thyroid.
A chance of exposure to low levels of radiation in the childhood.
How to diagnose the risk factors for acoustic neuroma?
If you are experiencing loss of hearing or other neurological symptoms, try to keep track of them. Later on, mention them to your doctor for a proper diagnosis. A detailed history of the symptoms will help your doctor. Your doctor will perform a hearing test to check whether you have an acoustic neuroma. Then the doctor may perform a brainstem auditory evoked response tests along with an electronystagmography to detect any changes in eye movement, caused due to the inner ear. MRI and CT scans are also quite common diagnoses methods for acoustic neuroma.

Acoustic Neuroma - What Are The Risk Factors?

Study of the brain has fascinated specialists all over the globe since time immemorial. The brain being the most vital organ for survival and coordination is perhaps the most complex of them all too. This has led to a limited understanding of its working in spite of the available advanced technology. However, with the advent of techniques for diagnosis and treatment, therapeutic strategies are evolving. This is a major step towards rendering Neurosurgery safer than ever in the history of mankind.

Neurosurgery through the 20th Century-

During the beginning of the 20th century, Neurosurgery was considered as a specialty. The clinical-neurologist would draw conclusions related to lesions in the brain through neurological examination and clinical history. It enabled diagnosis of vascular lesions, spinal disorders, and brain tumors. During the second and third decades of the 20th century, vascular pathologies and brain tumors could be diagnosed indirectly through techniques like angiography, ventriculography, and pneumoencephalography. But since the operative techniques were too crude and the lack of skilled professionals were rampant, there were high rates of morbidity and mortality due to neurological conditions. Generally, after diagnosing the nature of brain lesion and its site, surgery was performed with inadequate maintenance and control of intracranial pressure and through not too sophisticated surgical instruments.

During the fifth and sixth decades of the 20th century, chemotherapy and radiation treatment came into the picture for treating malignant brain tumors, thereby reducing mortality to a good extent.

During the seventh decade of the 20th century, Computed Tomography (CT) scan provided a better understanding of the location of lesions in the brain which slightly substantiated the earlier techniques. Then, the procedures for cerebrospinal fluid diversion significantly improved management of intracranial pressure during surgery.

It was only during the last decade of the 20th century that the Neurology saw a giant progressive leap through the introduction of Magnetic Resonance Imaging (MRI) and powerful high magnification microscopes. Combined with Neuroanesthesia and Intracranial Pressure Management, this aided surgeons to work on a relaxed brain. This promoted safe removal of the brain tumor and better management of vascular lesions. Moreover, the understanding of micro-surgical anatomy improved drastically, leading to a boost in confidence levels of the micro-neurosurgeons performing the operation.

Neurosurgery in the 21st Century-

The 21st century is actually a revolutionary era that uses powerful computers in almost all the fields possible. Computer-based applications such as Neuro-imaging, Neuronavigation, Intra-operative Neuro-monitoring, and Neuro-modulation are now used in standard neurosurgical practice as a part of the routine. Extremely powerful CT scans and MRIs are used for diagnosis before surgery. The advent of nanotechnology and its application in Neurosurgery is doing great and has a promising future ahead based on the current study of scenarios. Moreover, there is a possibility of most of the Neurosurgical procedures becoming minimally invasive. Frameless Stereotaxy is another technique that helps in locating the exact position of the tumor, which further helps the neurosurgeon in navigating with great precision the very sensitive, high-risk areas of the brain. Such techniques, to a great extent, have lowered mortality and morbidity, lessened the rate of recovery, and chances of infection related to Neurosurgery.

Take Away-

A number of techniques for diagnosis and precise location of the tumor in the brain have made Neurosurgery much safer today, due to advancement in science and technology, than it ever had been in the history of mankind.
