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.

Cancer indicates the growth of certain unusual cells, generally uncontrolled in nature, in any part of your body. It may also refer to a malignant tumor and it can affect any organ or any part of your body. There are many different cancers accordingly, such as lung cancer, bladder cancer, skin cancer or blood cancer. Ayurveda offers effective measures for preventing cancer. Read on to find more about the tips and get better prepared to fight this killer:

1) According to Ayurveda, having fresh foods can help you to prevent cancer. Consuming more of green leafy vegetables and fresh fruits may prove to be helpful.

2)Avoiding fat based foods or fried foods can be effective in preventing cancer. Strike off hydrogenated fats (such as cookies, peanut butter, crackers etc) or saturated animal fats from your diet.

3) Exercising on a regular basis may be very helpful. Stretching exercises, walking, breathing exercises and aerobics are considered to be useful preventive measures for cancer.

4) Meditation and yoga are also effective ways to prevent cancer. These can help you to reduce stress and remain calm.

5) Drinking green tea regularly can be very useful for killing any growth of cancerous cells in your body and thus help you to prevent cancer.

6) Cutting down on foods with higher quantities of sugar can help you to prevent cancer.

7) Include foods replete in vitamin D and vitamin C or citrus foods as these help to combat many kinds of cancer.

8) Incorporate spices like turmeric in your daily cooking regimen. The 'curcumin' present in turmeric coupled with a few other accompanying properties can help to prevent the growth of cancer cells in your body.

9) Garlic, whether consumed raw or cooked, can help you to fight the killer that cancer is.

9 Ayurvedic Tips to Prevent Cancer

According to a major study that provides a connection between height and cancer, it is stated that taller people are more prone to developing cancer. Research has found that the risk of developing any kind of cancer in women rises by 18% for an increase of every 10 cm in height. In men, the risk rises by 11%, even though height is not as major a factor as are obesity, smoking and a bad, unhealthy diet.

Several reasons have been put forward for the above statement. One of the reasons is that the number of body cells in taller people is more than people with average height. This leads to an increase in the number of cells which could potentially turn malignant.

While individually analysing the impact of height on different cancer forms, it was found that the highest increase in risk was in skin cancer (30% for every 10 cm increase in height), while a 20% increase was noted in taller women developing breast cancer.

Development of cancer in regions including the colon and rectum is known as colorectal cancer. Long legs have been surprisingly associated with this form of cancer. In comparison with shorter people, it was reported that taller people had a higher risk percentage of developing colorectal cancer. Two hypotheses regarding the formation of colorectal cancer have been developed. One hypothesis is that taller people have longer colons, which in turn result in more surface area where colon cancer can develop. The other hypothesis is that taller people experience increased levels of growth hormones. These particularly affect the length of their legs. The growth hormone called 'insulin-like growth factor 1' is increased during puberty and is considered to be a risk factor for colorectal cancers occurring at later stages.

How to become less prone to cancer

There are various known reasons why cancer takes root in a healthy body. The deadly disease takes away millions of lives worldwide and remedies in food to tackle it are constantly a subject of research. However taking this one food item off your daily diet can help becoming less prone to cancer.

Senior cancer experts stress that sugar feeds cancer. According to his belief, backed by years of research and medical expertise, it is possible to starve cancer out of a person’s body. When sugar breaks down in the body in a non-oxidative manner, adenosine triphosphate (ATP) is generated which causes cancer cells and tumor to grow.

Research states that cancer is a dysfunction of the mitochondria caused by fermentation of sugar in the cells instead of orthodox respiration of normal cells. This can be tackled by limiting the supply, just by cutting down the intake of sugar every day. A small amount of sugar in a healthy and requisite proportion is acceptable but excessive sugar must be avoided in order to choke cancer out from the body.

Specifically, the intake of sugar in processed foods must be cut down. Everything that is sweet isn't sugar! Avoiding processed foods will simply eliminate the bad salts and bad sugars from your diet. Eating at fast food joints too must be cut down completely as the food they serve is frozen and needs a lot of preservatives. You can always switch to fruits if you have a sweet tooth. Diet-wise, consume more green leafy vegetables, developing a plant and natural nutrient based diet is an ideal method to tackle cancer.

Neurodevelopmental disorders refer to any impairment and disorder of the brain and nervous system growth and development. Disorder in the brain and nervous system can affect the emotional, physiological, psychological ability and overall timely development of a child. With advanced technology and continuous study in the medical field, one can now assess the neurodevelopment of his/her children. Neurodevelopmental Assessment concentrates on the overall growth and development of a child including his/her weaknesses and strengths. A complete developmental profile is generated with the help of various tests and examinations. This assessment is used to analyse the various developmental factors including social and communication skills, functional and motor skills, cognition and learning abilities, and language and speech development. Neurodevelopmental Assessment involves a team of child s close people including parents, guardians, and family members who help to understand the medical history if any. It helps doctors to provide appropriate ways to assist the child in his/ her growth and development.

Tests and Examinations

Tests for the Neurodevelopmental Assessment may vary from child to child depending upon their condition. But, there are usually some tests that are done to understand the overall development of the child. These tests may include speech tests, hearing tests, blood tests, physical examinations, and questionnaires, which may be given before or during the assessment process.

Assessment

The assessment processes and sessions may vary depending upon the need of the child. However, usually, there are three major sessions that help the pediatrician understand the concerns of the family and parents. These sessions include consulting about the detailed medical history of the child, understanding the problem and its possible cause, and providing proper ways and treatment options for the patient. 

In the first session, parents and guardians are asked about any medical concern they have and the medical examination of the child is carried out accordingly. A standardized assessment with the child will be carried out by a clinical psychologist and the parents and guardians are asked to complete a questionnaire for the assessment. Depending upon the age, questionnaire may be sent to school for teacher/s to complete.

The next session is usually led by language and speech therapist to discuss and understand the current language and speech concerns of the child. Previous assessments and medical examinations are taken into account to carry out further assessments. An occupational therapist will assess the child s ability to perform self-care activities and other tasks according to his/her age. The session may include the assessment of a child s motor skills and abilities and reflection on any probable sensory-based problems that may be affecting the child s occupational performance.

The last session mainly includes the discussion with the parents and guardians to help them understand the problem, its causes, and treatment options. If the child requires any further assessment or/and recommendations, then the parents are told about that too.

Takeaway
Neurodevelopmental Assessment of children is often performed on kids who do not show the developmental signs according to their age. Parents and guardians should not hesitate to consult their children to clinical psychologist and therapist as the early intervention and assessment can help in the timely growth and development of the children.

Neurodevelopmental Assessment (0-5 Years)  - What Should You Know?

Brain tumor refers to the development of unusual cells in the brain or around the nearby tissues and structures. Pediatric Brain Tumor means the development of these unusual cells in the brain of children. There are two types of brain tumors: Benign or non-cancerous and malignant or Cancerous. Tumors like ependymoma and medulloblastoma are quite common among children. The treatment of the tumor is determined by its severity, type, location, age, and overall health of the child. The treatment of Brain Tumor in children is different from the adult s treatment. One should ensure to consult with the pediatrician with the specialty in cancer and neurology. Brain Tumors in children are Primary Brain Tumors that develop in the brain or nearby tissues. This Primary Brain Tumor develops when the usual cells have DNA mutations or alterations. The alterations in the DNA permit the cells to develop and distribute or split with an increased rate and destroy the healthy cells. This leads to the development and collection of unusual cells forming a tumor. In most Primary Brain Tumor cases, the cause is not clear. Children with a family history of the genetic syndrome and Brain Tumor are more prone to the problem.

Symptoms-

The symptoms of the Pediatric Brain Tumor depend upon the severity, location, and type. There are a number of symptoms that are really common and are shared by other diseases. Other than this, there are symptoms which are possibly the signs of Brain Tumor among children. Adults and parents should consult a doctor if they find their children having the symptoms and signs for an unusual time.

Hearing issues

Frequent and severe headache

Fuller fontanel (soft spot) on the baby s skull

Vomiting or nausea

Behavior changes

Seizures

Sudden vision problems like double vision

Abnormal or strange eye movement

Increased heaviness or pressure in the head

Irritability

Slurred speech

Difficulty in swallowing

Weakness

Loss of appetite

Drooping on one side of the face

Difficulty feeding in babies

Loss of sensation on one side of the body

Imbalance or difficulty in balancing

Difficulty in walking

Diagnosis-

The diagnosis for the Pediatric Brain Tumor includes many lab tests. The doctor may initiate with some neurological examination like hearing, vision, reflexes, balance, and coordination. Any abnormality in these tests will lead to further examinations. There are some imaging tests that are used to determine the size and location of the tumor in the brain. These tests include MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography), and CT (Computerized Tomography). After the confirmation of the presence of a Brain Tumor, the specialist will further move to the Biopsy. It includes the removal of a sample tissue for analysis or testing. The type of biopsy that will be performed on the patient depends upon the location of the tumor. Other than the biopsy, the tumor tissue can be examined for molecular basis and genetic mutations. After that, Drug therapy can be designed according to the individual s requirements. It is important for the doctor and the patient to know if the tumor has been spread through cancer in other parts of the body. If it is true, then the doctor will perform more tests and examinations to know the root and initial location of cancer for further treatment.

Treatment-

The treatment of the Pediatric Brain Tumor is determined by the severity, location, size of the tumor, and age and health of the child. There is a number of treatments available with modern technology but their usage depends upon the patient s requirement.

Surgery that is used when the location of the tumor is approachable via surgery. When the brain tumor is small, it can be completely removed by the surgery. But when the tumor tissues are located nearby sensitive areas of the brain, then the surgery becomes risky and maximum tumor tissues are tried to be removed through surgery. The risk of the surgery depends upon the location of the tumor. An example can be vision loss if it is anywhere near the nerves connected to the eyes.

Targeted Drug Therapy helps to destroy the abnormalities of the cancer cells resulting in the destruction of the cancer cells.

Radiation therapy is used to kill the tumor cells by using high-energy beams. Radiation therapy can either be given by an external machine (external beam radiation) or in exceptional cases, radiation is positioned within the body (brachytherapy) near the tumor.

Chemotherapy includes the consumption of drugs to destroy the tumor cells. These drugs can be consumed in tablet form but for children, the drugs are mostly injected (intravenous chemotherapy).

Stereotactic Radio Surgery includes various radiation beams to perform extremely focused radiation therapy to destroy the tumor cells located in a small part.

Proton Beam Therapy carries higher targeted radiation doses to the tumor cells with minimum exposure of radiation to the healthy cells and tissues. It decreases the chance of development of fresh cancer cells.

Take Away-

Pediatric Brain Tumor is the development of unusual cells in the brain or around it. Although this is a life-threatening problem, however, with advanced technology, it can be treated successfully. There are no specific causes discovered by specialists but genetic mutations and family history cause it. The symptoms can be really common like headache and nausea but can also be specific like difficulty in coordination, reflexes, speech, and many more. The timely diagnosis and treatment can give a new life to the child and reduces the chance of development of fresh tumor cells in the future.
