When it comes to the brain and the iq, is bigger the better? does size really matter? is there really a connection between the size of your brain and intelligence? with the help of findings by neurologists 
And scientists, we seek to find out!

1. Ailments and the brain: scientists have found that children with autism have a brain that has grown in a disproportionate manner in the very first year of their life. This prevents the child from making connections with normal behaviour. On the other hand, children and adolescents who suffer from attention deficit hyperactivity disorder or adhd have shown signs of having a much smaller brain size. Many scientists have shown that the size of the brain shrinks as we age, and this does not have any visible effect on our cognitive abilities.

2. It's all relative: the size of the brain does not really have a bearing on the way a person's cognition gets shaped. Even large mammals like elephants and whales are finally hunted and tamed by humans who have smaller brains in comparison. The brain is made up of billions of neurons which need to function properly. It may be seen that scientists consider the brain mass in relation with the rest of the body so as to speculate about the cognitive abilities of the person. Why is this required? large animals need a well functioning and proportionate brain size to control and run their organs with proper cognition for satisfactory results, which is what we humans seem to have done.

3. Neanderthal brains: historically, the earliest man or the neanderthals are said to have had larger brains than we do. These people are believed to have brains that are at least 10% larger than the brains that we have in our modern times. The shape of their brain was different too. They were also heavily muscled people which had a bearing on the size and shape of the brain and bodies as well as the lean tissue within the brain. They also survived very successfully for a period of over 200, 000 years, which obviously points to some form of elevated cognition, as per many scientists.

4. Animals: while animals with small brains like lizards and reptiles do not perform too well on iq tests, the animals with bigger brains like elephants and dolphins perform much better. But the medium sized brains of monkeys, lemurs and other animals are said to perform in the best manner. The correlation between the body size and the brain does not seem to hold good here, as per various researches.

So the verdict as per medical science and research stands divided!

Is There an Association Between Brain Size and Intelligence?

Cyclic vomiting syndrome (cvs) is characterized by periodic bouts of nausea and vomiting that happens at cyclical intervals. It affects all ages, but is more common in children. The condition is quite stereotypical in that there are paroxysms or bouts of vomiting that is recurrent and follows days of normal health.

Causes: there is no definite reason identified, but it is said to have a strong hereditary correlation. Studies have shown mitochondrial heteroplasmic (abnormal growth of mitochondria, which is a cellular component) to be one of the factors that can lead to cvs. The genetic correlation, however, is very difficult to establish, specifically because vomiting and nausea are common symptoms that occur with most conditions in children. And cvs is most commonly noted with conditions like infections and emotional excitement. Infection could be either tooth decay or sinusitis or anything else. Lack of sleep, anxiety, holidays, allergies, overeating, certain foods, menstruation - a host of factors have been shown to induce cvs. There is also a strong association with migraine and conditions that lead to excessive production of stress hormones.

Symptoms: the syndrome (a group of symptoms) usually has 4 phases:

1. Symptom-free interval phase: the child is completely normal in this phase, which happens in between bouts.

2. Prodromal phase: prodrome is an indication that a disease or a condition is about to happen. In cvs, this is usually nausea and abdominal pain that can last from a few minutes to a few hours. Treatment in this phase can curb the disease. However, there could be some children in whom this may not manifest and the child may directly start with vomiting.

3. Vomiting phase: repeated bouts of paroxysmal vomiting happen associated with nausea, exertion, fatigue, and drowsiness.

4. Recovery phase: as the nausea and vomiting begin to subside, which may take a couple of days, the child returns back to normal slowly. However, the lethargy and energy levels will take a couple of days to return to normal.

Treatment: treatment again depends on the severity and the phase at which it is being recognized. If a child has repetitive bouts, then the parent and the doctor would have identified a pattern to it.

1. If the causative agent has been identified, for instance, infection or migraine, then managing that takes care of the cvs also.

2. If identified during the prodromal phase, again it can be managed with suitable anti-emetic medications.

3. If identified after full onset, rest and sleep and medications to control nausea and vomiting are required. Adequate hydration with electrolyte replenishment and sedatives can provide additional support.
However, in most cases of childhood csv, the pattern will be identified and that helps in better management, both the child/parent and the podiatrist.

This is very similar to doing physical exercise which makes the muscles denser and stronger. The increase in functional capabilities of brain is based on the concept of neuroplasticity, which states that our intelligence is not based on genetics and there are some things which can be done to improve the way our brain works. Meditation is a good brain enhancer with an ability to increase intelligence.
 Beneficial brainwave patterns can be seen: meditation can help to guide the brainwaves into beneficial frequencies. The frequencies: alpha, theta and delta when guided can show case a myriad of benefits including idea generation, creativity, cognitive functioning, and intellectual capacity.

How to Build your Self Esteem?

Every person is familiar with the remark  Stop fidgeting  but does anybody ever wonder why do humans fidget? Is there any scientific reason for such an action? This article will throw light on the underlying causes for what is known as fidgeting.

Fidgeting and its underlying causes

Scientific research has revealed that fidgeting has many benefits still most people get annoyed when they see another person twitching and tapping. Most people do this seemingly without any control over their movement when they are ordered to be still. Research shows that there is at least one biological reason to back this action.
Since the same brain area is used for movement and speech, it is only natural that gestures are interlinked with thorough preparation for a speech. People tend to move their hands more when they are looking for a word to say, but are not being able to find it. In a recent study, it was found that school children between the age of 6-8 years who use their hands a lot can come up with the right answers during lessons.
While this is one theory, another neurological theory suggests that a portion of the mental load is off-loaded through the process of fidgeting when people have to tackle complex problems or thoughts. The theory is called cognitive load hypothesis. The offloading mechanism frees up the mental faculties thus, devoting them to the mental process. While this may not be a definitive explanation for fidgeting, it does go to show that there is a link between a person s hand movements and their thought and speech process.
Other reasons for fidgeting

Other than the cognitive advantages, some evidence has also been found linking fidgeting with metabolism. People who fidget are found to have a higher metabolism and lower BMI. This difference can be seen between thin and overweight people. Fidgeting amidst lollygagging during the day helps burn up to 350 calories a day. Also, fidgeting among other incidental physical activity helps keep an individual fit.
Among other reasons, fidgeting also serves as a coping mechanism for people with ADD. If a person is engaged in something that he/she is not interested in then the additional sensory-motor input that is even slightly stimulating or entertaining helps the brain to get completely engaged. This helps to maintain focus on the actual activity being performed by the individual.
So, fidgeting helps distract that part of the brain that is getting bored. This helps the other parts of the brain focus better on the actual activity. This is known as floating attention which perhaps is an evolutionary trait that dates back to prehistoric times. In those times, the ability to focus entirely on a task with undivided attention was not favorable to the human since doing so could make them unaware of the enormous ravenous beast hiding behind the bushes.
Thus, though there is some degree of understanding is there when it comes to fidgeting, more research studies are required to gain further insight. Consult an expert & get answers to your questions!

Fidgeting - Why Do We Do It?

Psychiatric disorders like bipolar disorder or schizophrenia do not appear all of a sudden. There are small changes that happen to an individual over a long period of time until the disease fully develops. These signs and symptoms might be too subtle in the early stage for other people to notice until they become obvious. But an early detection of any irregularity proves to be more beneficial for the patient in the long run.

It is important to know the telltale symptoms of mental disorder to distinguish between what is regular and what is not.

Withdrawal
Everyone needs some quiet time to cool off and relax but if a person continuously withdraws him/herself from social occasions and avoids meeting or speaking to friends, it could be a sign that something is wrong. Losing interest in life, work and people are symptoms of depression and psychotic disorder.

Thinking problems
Having trouble concentrating, remembering, understanding and explaining oneself in a coherent manner are some common signs of mental disorder.

Anxiety
Excessive stress and anxious behavior for a prolonged period are not normal. Frequent heart palpitations, headache, shortness of breath, racing mind and restlessness are cries of help that need to be heard.

Emotional outbursts
Sudden dramatic outbursts for no apparent reason, frequent mood swings and feeling distressed are potent signs of mental illnesses. These kinds of behavior are seen as part of a person's nature and so they are often unnoticed.

Changes in appetite and sleeping patterns
Oversleeping may be a sign of depression and insomnia could be a sign of anxiety. Changes in appetite and not caring about oneself or the world are indicators of a mental problem.
