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?

The neurones in the brain are constantly reorganising their connections both functionally and physically according to the environment, your thinking and behaviour. This ability is known as neuroplasticity. Through neuroplasticity the nerve cells of brain can compensate for injury to some parts of the brain and enable a person to recover from stroke, birth abnormalities. It is also beneficial in treating autism, ADD, learning disabilities and helps manage obsessive compulsive disorders.

Here are seven things you should know about neuroplasticity.

Change depends on the attentiveness of the brain: Neuroplasticity changes can only happen if the brain is alert and active. When the brain is active it releases neurochemicals that are necessary for the neurone connections to change. If a person is distracted to inattentive, these changes cannot happen.
The more the effort; the bigger the change: Neuroplasticity changes depend on how motivated the person is to change or learn new tasks. For this reason, when it comes to using neuroplasticity for physiotherapy, it is essential to first deal with any depression or anxiety issues the patient might be having before attempting to rehabilitate them.
It helps strengthen neural connections: Repetition of actions is one of the key elements of neuroplasticity in physiotherapy. Through this, the strength of neurone connections is strengthened to include sensory information, movement and cognitive patterns.
It improves cell to cell connections: This is crucial to a patient s rehabilitation as it increases reliability and makes a person more independent. In turn, this makes behaviour patterns more reliable.
It helps predict actions: A task can usually be broken down into a series of smaller tasks. For example, feeding oneself can be broken down into steps that begin with lifting a spoon and filling it with food to finally putting the spoon into your mouth. Hence, along with completing an action, the brain must also know what to do next. Neuroplasticity helps improve this associative flow and allows the brain to predict the next step.
Changes can be temporary or permanent: Initial changes due to neuroplasticity are temporary ad only if the brain determines the experience to be desired is this change made permanent. This is why when treating mobility issues, patients are not always able to repeat tasks in the same way.
Memory guides the learning: When making new neural connections through neuroplasticity, the brain is taught to discard unsuccessful attempts and only remember the experience of the successful attempts. From here, adjustments are made to improve the connection.

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?

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?

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!

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.
