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?

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?

Antibiotics are something which have changed are lives for eternity as well as for the better, to say the very least. With each day that passes, there are greater strides of advancement which are made in the field. Of late, it is said that antibiotics also have the potential to stop new cells in the brain from growing, which is quite a risk when it comes to their usage among people are sick.

Research has found that if the brain of the person under treatment is subject to sustained use of antibiotics, it is true that the brain can lose its functionality for a quicker time than what one would consider to be normal. So it can be said, this usually is not the advisable way to go.

Like most testing practices when it comes to medication, antibiotics which were tested on the brains of the subjects i.e. those of mice had an effect of mitigating their high-level memory. How this happened to be is rather interesting, to say the very least.

How dangerous can antibiotics be?
It is often said that eating right does wonder for a person s brain. Well, the mice that were not treated with the antibiotics were seen to lose the healthy bacteria present in their stomachs. In addition to this, they lost new brain cells. This led on to them performing worse in mental tests than their peers who had had some antibiotics administered to them on a consistent basis.

Now a cynic may point out that what is seen to be true for mice may really not hold true when it comes to humans being considered. However, if it is taken into due account that a lot of path-breaking research is carried out on mice, there is quite some credence to the results of the study.

To supplement the evidence even further, it was also seen that for mice which were in possession of low levels of monocytes, which are a type of white blood cells. It was seen that there was a great dependency on monocytes for the generation of white blood cells. The part of the brain which is hindered by generating new cells on account of the sustained use of antibiotics is the hippocampus.

Antibiotics are the proverbial shot in the arm which can aid recovery by destroying the threat to a person s wellness. However, it is to be considered that they are not safe in general as there is collateral damage!

Antibiotics - Can They Stop The Growth Of Brain Cells?

Neurological disorders are the diseases of the brain and spine, and the nerves which connect the brain and spine.

Some of the most common types of Neurological disorders are:

Alzheimer s Disease (AD)

Multiple Sclerosis

Epilepsy

Migraines

Parkinson s Disease

Ayurvedic Approach of Neurological Disorders

Ayurveda is an ancient system of medicine which originated in India, having a holistic approach to focus on treating the entire being. Ayurveda treatments are based on vata, pitta, and kapha doshas, whose balance leads to harmony and whose imbalance leads to toxic accumulations inside the body. Ayurveda aims to maintain an equilibrium among the three. It has effective solutions for a number of Neurological Disorders, also called  Vatavyadhi .

Eighty types of Vatavyadhi are described in Ayurvedic texts which can be placed under four categories: Kevala vata (Vata alone), Samsarga (Vata in association with Pitta and Kapha), Avarana (due to entrapment by other Dosha/Dhatu/Mala), and Dhatu Kshaya Janya (neurodegenerative). 

Ayurvedic Treatment

Ayurveda is plant-based systems of medicine. Because of being natural and harmless, it is very popular in treating various diseases. Several herbs have excellent properties to treat panic and anxiety affecting the central nervous system. Nature s gift of herbs and minerals not only alleviates symptoms but ensures cure by regulating neural biokinesis, thus preventing recurrence, relapse, and adversity.

Ayurveda can cure a number of Neurological Disorders like migraine, sinus, Parkinson s disease, anxiety, stress, insomnia, epilepsy, hysteria, cerebral palsy, stroke, etc. For treating these Neurological Disorders Panchakarma therapy is adopted which focuses on holistic treatment for long-lasting results.

Some of the common remedies under Panchakarma therapy are:

Chamomile tea, roots of kava, passion flower, ginseng, Cannabis sativa are all prescribed for anxiety.

Valerian is used as a natural sedative and for treating insomnia and panic attacks.

Ginkgo biloba and Hypericum perforatum have neuroprotective properties and are useful in treating learning dysfunction and improving memory.

Inhaling powder of seeds of Achyranthes aspera or Prickly chaff flower relieves from stiffness and migraine.

Bark powder of Acorus calamus or Sweet flag root enhances memory by curing forgetfulness. When consumed with honey, it is beneficial for anxiety and epilepsy. Equal weights of this powder with ginger powder is recommended for facial paralysis.

Powder of Malabar nut with honey cures epilepsy.

Seed powder of Siris tree is used for treating insanity, psychosis, anxiety, and hysteria.

Coriander extract relieves vertigo and headache.

Juice of Dodder plant or Amarbel is taken in water to improve brain disorders.

Extract of branches of peepal tree cures madness.

Decoction of roots of drumstick plant is given for epilepsy and hysteria.

Velvet bean is effective in treating Parkinson s disease.

Poppy is beneficial in sleeplessness, delirium, convulsion, etc.

Decoction of leaves of guava is used to cure physical and mental deformities.

Leaves of pomegranate, when concentrated in boiling water and given in warm milk, cures fatigue and insomnia.

Leaves of pomegranate and rose petals when concentrated in boiling water and given in ghee, cure madness.

Cloves paste in water is applied on earlobes to cure migraine.

Almonds improve memory, especially when taken at an early age.

Yoga and meditation help in improving mental health by incorporating discipline and relaxation.

Take Away

For reliable cure with minimal side effects, Ayurveda is very well developed for treating many brain-related disorders with an approach of maintaining equilibrium among the three doshas and towards holistic, long-term treatment.

Neurological Disorders - How Ayurveda Can Assist?

Cerebral palsy is the term for a group of neurological disorders that affects one s muscle movement and motor skills.

In most cases, the condition is caused due to a brain impairment that develops while the baby is still in the womb. Cerebral palsy may also occur shortly after or during birth.

Symptoms of Cerebral Palsy:

The signs and symptoms of the condition vary from one individual to another, ranging from mild to severe. The commonly observed ones in children are-

  Difficulty walking
  Difficulty holding on to objects
  Delay in developing motor skills- sitting up straight, rolling over, crawling
  Variation in the muscle tone- too stiff or too floppy
  Delay in development of speech
  Spasticity
  Lack of coordination of the muscles
  Difficulty swallowing and excessive drooling
  Functioning of only one side of the body
  Neurological ailments such as intellectual disabilities, seizures, and others

Types of Cerebral Palsy:

Cerebral palsy can occur in the following forms-

  Spastic cerebral palsy - Causes exaggerated reflexes and muscle stiffness. This is the most common type of cerebral palsy, affecting nearly 80% of the population.
  Dyskinetic cerebral palsy - Causes abnormal, involuntary movement of the legs, arms, and hands. It may also affect the movement of the tongue and face, thereby making it difficult to talk or swallow.
  Hypotonic cerebral palsy - Causes overly relaxed muscles and reduces muscle tone. The legs and arms are easily moveable and appear saggy.
  Ataxic cerebral palsy - This is the least common type. People living with this form of the condition have problems with coordination and balance.

Diagnosis and treatment of cerebral palsy

Cerebral palsy can be diagnosed with the help of the following-

  CT scan
  MRI
  Ultrasound
  Electroencephalogram

Treatment of the condition depends on its severity. Long-term treatment includes physiotherapy, medications and surgery.

  Physiotherapy and occupational therapy helps restore muscle strength and improves muscle tone. You can try stretching exercises to improve flexibility.
  Usually, the doctor prescribes medications in the form of muscle relaxants and sedatives. Muscle relaxants reduce muscle tension, helps relieve discomfort and muscle pain.
  You may need to undergo an orthopaedic surgery in case medications and therapy does not yield positive results. The surgery will aim to release tight muscles and repair bone abnormalities caused due to spasticity.

The specialist as a last resort may recommend SDR or Selective Dorsal Rhizotomy to reduce spasticity and chronic pain. This involves operating the nerves at the base of your spinal column.

There is no permanent cure for cerebral palsy. However, the condition is manageable with the help of drugs, therapy and surgery. The kind of treatment required depends on your overall condition. While some may be able to live with the condition without much assistance, others may require immediate medical intervention. Therefore, it is best to consult an orthopaedic and get help if the symptoms deteriorate over time.

Cerebral Palsy - Symptoms, Types & Treatment Of It!

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.
