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.

Acoustic neuroma is a benign tumor that occurs in the primary nerve between the brain and the ear. The tumor progresses very slowly and can influence your balance and hearing. In certain cases, if the tumor becomes very large, then it may also impair vital functions of the body.
Symptoms-
The symptoms of acoustic neuroma tend to develop when the tumor starts to press on the nerve and its adjoining branches. The symptoms of this disorder are  
You may experience hearing loss on one side which might worsen gradually.
You may have problems in balancing yourself.
A continuous ringing sound in the ears.
Persistent dizziness.
If the tumor is large and presses on the nearby nerves, then you may experience numbness of the facial muscles.
In some cases, it may impair the vital functions of the body.
This disorder is caused by a malfunctioning gene. There is no documented reason as to why the gene malfunctions.
The treatment options for this disorder are  
Constant Monitoring: These tumors tend to grow very slowly but might spurt in some cases. In order to prevent damage to your body, they need to be monitored on a regular basis. Imaging tests are recommended on a periodic basis to determine the growth of the tumor.
Radiosurgery: Stereotactic radiosurgery is done to treat acoustic neuroma that is small in size. In this surgery, radiation is directed at the tumor without creating any incision. It is done to limit the growth of the tumor and preserve your hearing.
Surgery: The tumor can be removed by using surgical procedures. It involves administering general anesthesia, followed by removing the tumor through an incision on the skull or the inner ear. Surgery is used to remove the tumor and preserve your hearing abilities. 

Acoustic Neuroma - Everything You Need to Know

Polio is a virus that has the potential to infect any parts of the body including, but not limited to nerves and muscles. Primarily there are 3 types of polio namely, non-paralytic, spinal paralytic and bulbar. This disease shows minimal to no symptoms in more than 90 percent of the cases. 5 percent of the cases can show symptoms such as nausea, diarrhea, vomiting, sore throat and abdominal pain. Polio is a communicable disease and can cause massive damage if a proper dosage is not taken. It can spread through air, physical contact with an infected person, coughs etc.

Polio can cause paralysis: Polio has a far-reaching permanent effect on the body. It can cause paralysis on any of the limbs leading to permanent disability. This severely alters a child s life. The far-reaching consequences of the virus can only be negated through vaccination.
Weak muscle: Polio can result in weak muscles, respiratory problems and loss of reflex. If the breathing muscle collapses, it can result in the death of a person. Any of the above-mentioned symptoms can lead to weak body development altering the fate of a child.
It can spread fast and quick: Polio spreads very fast through the air, physical contact, saliva and water. It not only affects a single life but put millions at risk of the disease. A 1916 outbreak of the disease killed 6000 people in the United States and left several thousands of people disabled.
It reduces the risk of infection: 3 dosages Polio vaccination under the age of 6 can save a baby from getting polio in future. The body successfully creates polio antibodies from the vaccines and gets enough ammunition to fight it if the virus attacks it in future.
Social responsibility: Massive amount of awareness campaigns have been run by countries all over the world to permanently eradicate polio from the face of the earth. As per the latest reports, only 3 countries are reported to have babies affected with polio; Afghanistan, Pakistan and Congo. It is, therefore, a social responsibility to take part in the mission of removing polio from the face of the earth once and for all.
Save future generation: Although polio is not known to be a disease which passes through heredity, there still lies a chance for the future generation to get this disease. In order to negate that from happening, it makes sense to get the vaccines on time.
Give your kid a head start: Every kid deserves to have an equal amount of privileges like others. One small mistake on part of the parents can heavily cost a child s future. In order to make sure your kids grow up with any apprehension of polio, it is very important to treat them with polio vaccines.

Polio Vaccination - Why Is It so Important?

Whether it's a child or a grown-up, difficulty in concentrating is often experienced by many people. While, people tend to brush off this particular problem to be nothing worth being concerned about, but sometimes, there may be a more serious underlying issue for which concentration problem is only a mere symptom. Yes, difficulty in concentrating can be a sign of a neurological disorder. Keep on reading to know more about neurological disorder, its symptoms, and treatment.

Reasons behind difficulty in concentrating
Inability to focus properly is a periodic and normal occurrence for many. While sometimes it is the emotional stress or physical tiredness that is responsible for it, at times it is the outcome of hormonal changes in the body, such as during pregnancy or menopause that causes it. However, when experienced in severe degrees, it may be a characteristic of a serious psychological condition called neurological disorder. Affecting both adults and the children, the neurological disorder can be a serious threat if not treated at the right time.

Neurological disorder
Neurological disorder refers to any condition that happens due to the dysfunction of the nervous system or the parts of the brain. Depending on the location of the damage to the nerve or in the spinal column or the brain, different areas controlling the vision, movement, thinking or hearing can be severely affected. The decreased ability to focus on something or loss of concentration power being one of the many symptoms of neurological disorders among the various complications it causes.

Causes behind neurological disorder
Many reasons lead to neurological disorder or its associated symptoms like difficulty in focusing. From lifestyle-related issues to nutrition related causes, physical injuries to some infections, complications during childbirth, and genetics to environmental influences, numerous factors can be responsible for such disorder. Depending on the type of neurological disorder, the symptoms can vary from to another, while for some difficulty concentrating can be a symptom, for some, the symptoms can be more of physical difficulties such as problems in walking or difficulty speaking or seeing, etc.

Dealing with difficulty concentrating
Once the cause of the neurological disorder is determined, there are various treatment options, offered by the doctors. To deal with the neurological disorder as the cause of difficulty concentrating one may need medications and treatment provided by the medical professionals. However, there are a few tips that one can keep in mind, such as minimizing multitasking and focusing on one single thing or thought at one time or dividing tasks into small steps, etc.

Difficulty in concentrating means the ability to focus on thoughts or action decreasing. In case one experience this issue on a long term basis or excessively, visiting the neurologist as soon as possible should be the best thing to do.

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.

Obesity - How It Affects The Human Brain?

Trigeminal neuralgia is specified by the condition of a chronic pain that influences the trigeminal nerve. This nerve transfers sensation from one s face to his/her brain. If a person is suffering from trigeminal neuralgia, then a gentle stimulation of face (sourced from brushing teeth or applying makeup) might generate a fright of agonizing pain. The affected person might experience short and mild attacks initially. However, the trigeminal neuralgia might progress and generate more-frequently and longer attack of severely critical pain. Women get affected by this situation more than men get and it is more prominently occur in individuals older than 50 years.

Trigeminal neuralgia does not mandatorily mean that you need to experience a lifelong pain. Various types of treatment alternatives are available and so doctors can usually handle the particular condition effectively by taking help of injections, medications or surgery. Various types of triggers might cause the pain regarding trigeminal neuralgia, such as eating, drinking, shaving, brushing teeth, touching face, smiling, washing face etc.

Symptoms

The symptoms of trigeminal neuralgia might comprise of one or more patterns and some of these are described below:

Sequences of serious, jolting or shooting pain that might generate as an electric shock
Spontaneous pain attacks or attacks stimulated by different activities like face touching, speaking, chewing, or brushing teeth. Pain attacks last from a few moments to some minutes.
It is not a comprehensive list because Trigeminal neuralgia hosts various other symptoms as well. If a person feels facial pain, specifically recurring or prolonged pain or if the person does not get relief through the utilization over-the-counter pain relievers, then that person must consult a doctor.
How does Radiofrequency Ablation treat Trigeminal Neuralgia?
Trigeminal Neuralgia is a chronic and painful condition that involves the trigeminal nerve. There are two separate trigeminal nerves on both sides of the face, which carry the sensations like pain from the face to the body. Each nerve has three branches- forehand, midface and chin and trigeminal neuralgia can cause intense pain in any of these areas.

Causes-

This occurs when the trigeminal nerve functioning is disrupted. When the blood vessel/artery and the trigeminal nerve at the base of your brain come in contact, it puts pressure on the nerves and causes pain.
It also occurs as a result of ageing or multiple sclerosis
A disorder that damages the myelin sheath protecting the nerves can trigger pain
Sometimes pain occurs from tumors, which compresses the trigeminal nerves
Surgical strokes, facial trauma or strokes can also be the root cause of excruciating pain
Triggers-

Shaving
Touching your face
Eating and drinking
Putting on makeup
Brushing
Washing your face
Symptoms-
The pain can be mild and for a shorter duration or it can happen frequently for longer durations. Some experience the pain in cycles where it can come and go for days or even for weeks. Gradually the intensity of the pain lessens.

Cure by Radio-frequency Ablation
The treatment of trigeminal neuralgia is often a challenging process in clinical practice. When medicines do not prove as effective, surgery is the desired option.

Procedure-

After applying local anaesthesia, the Pain Specialist carefully inserts a needle through the corner of your mouth to reach the trigeminal nerve
The doctors then wake up the patient after stimulating the nerves and ask them to feel the stimulation at the same place where they undergo pain. This confirms their targeted location
Once you fall asleep again, the Pain Specialist uses radiofrequency heat to injure the nerve enough to create numbness and removes the pain
How Effective is Radio-frequency Ablation?
The pain is cured almost in 98% of the patients. 50% of patients report recurrence of pain after about two years. Hence the procedure can be repeated in the same patient if necessary.
