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?

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.

Trigeminal Neuralgia And Radio-Frequency Ablation - What Causes It?

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.

Problem In Concentrating Could Be A Sign Of Neurological Disorder!

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.

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?

Acoustic vestibular schwannoma or the acoustic neuroma is a kind of tumour. But this tumour is benign which means it is non-cancerous. The vestibular nerve connects your ear to your brain, it is responsible for hearing and balancing. An acoustic neuroma develops on the vestibular nerve. And it can cause hearing impairment.

How does acoustic Vestibular Schwannoma occur? 
The vestibular nerve is lined with Schwann cells. Sometimes, these cells start to develop rapidly. This forms a mound on the nerve, it slowly becomes large enough to prod against the brain, and this adversely affects the actions of the brain.

What are the Symptoms?
In the early phases, the tumour does not trigger any symptoms. They begin to manifest once the tumour starts expanding. Here is a list of the symptoms of acoustic vestibular schwannoma-
  Gradual hearing loss
  Misalignment and losing balance
  Ringing in the ears.
  Regions of numbness in your face
Even though these tumours are benign, sometimes they enlarge to such an extent that they can be harmful to the brain. As soon as you witness the above-mentioned symptoms, book an appointment with a doctor.
With timely treatment and medication, doctors can reverse the growth of an acoustic vestibular schwannoma. 

What triggers this Disease?
The exact cause of this disease is not known. It could be any one of the following-
  A chromosomal anomaly or a malfunctioning gene
  Inhibition in the function of the protein suppressor that regulates the growth of Schwann cells

How is Acoustic Vestibular Schwannoma detected?
Your doctor will recommend these tests-

  Audiometry -
The audiologist will present sounds at different frequencies and you will have to make a gesture whenever you hear a sound. This will reveal the state of your hearing.

  Magnetic Resonance Imaging -
An MRI can detect the presence of a tumour that is 1-2 mms in diameter. If MRI causes pain or discomfort, a CT scan will be done.

Treatment -
If the tumour is tiny, your doctor won t prescribe medicines but your tumour will be monitored and imaged regularly so that the proper action can be taken as soon as it begins to enlarge.

  Surgery -
If the tumour is large, then you might have to undergo surgery. Not only will the tumour be removed, but also care will be taken to preserve the facial nerve so that facial paralysis does not set in.
You will be placed under general anaesthesia. The surgeon will drill a small hole in your skull near the ears and extract the tumour through your inner ears.

  Radiation -
If the tumour is small or if the patient is elderly and surgery can cause complications, doctors suggest radiation therapy. In this therapy, gamma rays are directed towards the tumour to shrink it.
Acoustic vestibular schwannoma can be treated if diagnosed on time. So, if you have noticed any symptoms, talk to a doctor right away.
