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?

Every person suffering from migraine will agree that -  although medications can control the head-piercing pain that each attack brings with it, preventing the onset of the pain altogether is the best way to deal with it.

Epilepsy is a disease that affects the brain's nerve cells and triggers the release of abnormal electrical signals. This can cause temporary malfunctioning of the other brain cells and result in sudden loss of consciousness. Epilepsy can affect both children and adults.

Epilepsy can be treated in a number of ways. One of the most preferred forms of treatment is homeopathy. Homeopathy addresses both the physical symptoms of the disease and the underlying factors triggering it. Another big advantage of homeopathic treatment is that it has negligible side effects.

A few homeopathic remedies that can be used to treat epilepsy are:

Cicuta
Cicuta is very effective when used to treat cases of epilepsy where convulsions are marked by violent, body distortions. This can include the horrific backward bending of the spine. These convulsions also make the person's face turn blue and trigger a locked jaw. This can also be used to effectively treat epilepsy cases triggered by head injuries and worms.

Artemisia vulgaris
This is used to often treat cases of petit mal epilepsy which are characterized by staring into space, leaning forwards or backwards and stopping a sentence abruptly. It also addresses fear that triggers epileptic attacks.

Stramonium
Convulsions triggered by exposure to bright lights or shiny objects can be treated with this homeopathic remedy. In such cases, the patient may not lose consciousness but experiences jerks in the muscles of the upper body.

Cuprum met
This homeopathic remedy is used to treat seizures that are preceded by experiencing an aura in the knees. Other symptoms that characterize this sort of an epileptic attack are spasms that begin in the fingers and toes and gradually spread to the rest of the body and jerking of muscles. This can also be used to treat convulsions that accompany menstruation and follow the delivery of a baby.

Bufo rana
Not all epileptic attacks occur you are awake. Attacks that occur in your sleep can be treated with bufo rana. Such epileptic attacks are accompanied by experiencing an aura in the genital regions. This is especially helpful for women who experience seizures during menstruation.

Hyoscyamus
Some epileptic fits are followed by a deep sleep. This type of epileptic attacks can be treated with hyoscyamus. Other symptoms addresses by this homeopathic medicine are fidgeting with bed clothes, fidgeting with fingers and muscular twitching.

These homeopathic remedies can be taken on their own or in combination with other medicines.

Top Homeopathic Remedies for Epilepsy Treatment

Injuries are very common, especially head injuries are one of the leading causes of death and disability in adults. As per surveys conducted, 1.7 million people suffer from head injuries every year and this estimation is increasing day by day.

There are several types of head injuries from mild as a cut, bruise, bump, contusion to severe ones caused due to a concussion, fractured skull bone, deep cut, internal bleeding, brain damage, etc.

A head injury is a comprehensive term which consists of an array of injuries that damage the skull, scalp, brain, and blood vessels and tissues in the head. It is generally referred to as a traumatic brain injury (TBI) and brain injury, depending upon the type and extent of trauma.

Causes of Head Injury-

A head injury can occur due to many reasons. Some common causes of these head injuries are:

Vehicle accidents

Domestic violence

Street fights

Fall from height

Child abuse

Subdural hematomas

Brain hemorrhages

Symptoms of Head Injury-

A head injury is followed by various symptoms depending upon the intensity of the injury. Here is a list of all the possible symptoms of brain injuries:

Nausea and vomiting.

Fatigue or sleepiness.

Extreme headache.

Confusion.

Loss of muscle control or paralysis in the part of the body controlled by the part of the brain that is affected.

Coma.

Dilation of the pupils and related visual problems; Blurred vision, photosensitivity, blindness, loss of muscle control in the eyes.

Cerebrospinal fluids might come out of the ears and nose, sometimes accompanied by blood.

Problem breathing.

Low pulse rate.

Increase in blood pressure.

Difficulty in swallowing.

Loss of hearing.

Problems in cognitive functions.

Numbness or tingling in the limbs.

Loss of bladder and bowel control due to loss of control over muscle functions.

Loss of consciousness.

Treatment of Head Injury-

Diagnosis of a brain injury has to be detailed and very quick at the same time. It always comes under emergency cases. Some of the steps involved are:

Cardiac and pulmonary function test.

Glasgow Coma Scale test.

Pupil dilation and corneal function test.

Brain stem reflex tests.

The most common way of diagnosis is the use of CT scans and MRI scans.

A severe head injury often needs surgery to reverse symptoms like chronic fatigue, bleeding, or loss of bodily function. Diagnosis involves finding out the type and severity of the injury and treatment involves removing the problem surgically.

Take Away-

Head injuries take time to heal, but medical treatment along with neurosurgery can aid the process of recovery and also help a person to lead a healthy life in the future. Most young patients recover fully, while some older patients or patients with preexisting neurological conditions live with a degree of disability.

All You Must Know About Head Injury & Its Treatment!

Obesity is the new-age lifestyle disease with multiple ramifications. While its effects on the physical aspects are very evident, the damage it does to the brain are more severe, though not obvious. Read on to know some harmful effects of obesity on the emotional well-being.

Leads to binge eating: There is a certain pleasure in eating sugary and fatty food, and this is lost with depression. Therefore, to get that emotional satisfaction, people tend to eat more chocolates, cookies, milkshakes, and other weight-accumulating food items, which further add to obesity. Greater the weight gained by a person, lesser the response or happiness from such food products.
Increases impulsivity: The area of the brain known as orbitofrontal cortex, which is in charge of controlling impulsivity, shrinks in obese people. This results in people eating more impulsively.
Affects immunity: Obesity is a major cause of inflammation, leading to damage in certain parts of the brain. This impairs the immune system, making the affected person more prone to infections and tissue damage. This leads to increased chances of diabetes, heart disease, stroke, sleeping disorders, eating disorders, etc. The chemical known as C-reactive protein increases as seen on MRIs in obese people, and which is usually seen in patients with chronically increased inflammation.
Effects on memory: As the BMI increases, there is a decrease in scores of memory tests. This effect is more obvious in women after menopause. With increased fat accumulation, more hormones are released, which affects the memory. Increased inflammation also affects cognition and memory.
Increased risk of dementia: With more belly fat accumulating, there is extra stress on the body to burn the visceral fat. This reduces brain size and causes certain hormones to release, which further affects the body s ability to remember things. It has been proven that people with smaller brain size are at greater risk for developing dementia.
Weight loss stress adding to more stress: When obesity sets in and the BMI goes up, there is an added pressure to lose weight, which further ups the stress levels. During these dieting days, the brain is constantly alert and finds ways to eat more. This also leads to excess eating. Moreover, there are indications that there could be genetic changes during this phase, which may leave a permanent mark in the person s composition.
Depression: When a person is not happy with their reflection in the mirror, the chances of feeling good and happy are very less. In this age, where aesthetics plays a major morale booster, an obese image staring back does not help at all.
So, if you have a risk of obesity, watch out. It is not just how you look, but how you feel is also altered.
