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?

Depression is often equated with isolation and brooding but this is not always the case. Many people may actually suffer from depression without showing the typical symptoms of this condition. Hence, this form of depression may go unnoticed for many years. Such cases are known as high-functioning depression. Some of the symptoms of this condition include:

Having difficulty expressing happiness: Though a person may be able to work normally, a person suffering from high-functioning depression will find it difficult to express emotions such as happiness. Thus he or she may not know how to act in the event of a promotion at work, the beginning of a new relationship or any other such happy events. In such cases, the happiness a person experiences from these events is temporary and muted.
Lowered energy levels: Unlike not being able to get out of bed when suffering from typical forms of depression, a person suffering from high-functioning depression can follow his or her usual routine. However, they often find themselves lacking the energy they would normally have and feel the need to put extra effort into their normal tasks. This reduces the amount of satisfaction derived from completing tasks.
Persistent self-doubt: While being self-critical is good to a certain extent, a person suffering from this form of depression is rarely satisfied with their work. Even when recognised by their peers or given an award for their work, they feel that this praise is misguided and have trouble accepting it. Thus, suffering from this condition is akin to swimming a race against the current and with additional unnecessary weights.
Substance abuse: Since this form of depression can go undiagnosed for many years, patients often turn to alcohol and other addictive substances in frustration. This can further delay diagnosis as many of the symptoms of this condition can also be attributed to substance abuse.
Feeling like a failure: Many people suffering from this condition feel as though they are constantly wasting time no matter how much they achieve in a day. This can make them feel hopeless and cause frequent changes in jobs.
The good news is that depression can be cured. Hence if someone around you or you, yourself experience such symptoms, talk to a doctor. Alternatively, you could make a few changes in your lifestyle to lift your mood. Try meditating in the morning or fit in some light exercise into your day. You could even take up a new hobby. However, this cannot replace cognitive therapy and psychological counselling.

 Utilizes the brain: almost everyone uses one half of their brain more and this leads to imbalance. Meditation is believed to sync the left and the right hemispheres, thereby allowing neural connection and great processing power. When logical left and creative right brains start working in harmony, then solving problems becomes easy; and it also increases creativity, deep thinking comes to be known of and concentration and focus magnifies. Highly successful people usually display whole brain synchronization.
 Functional capabilities of brain enhance due to meditation: research backs it that meditation increases the gray matter thickness of the brain regions, thus making the brain smarter, bigger and faster. 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. Meditation helps to transform these beneficial states of mind and help boost the iq.
 Develops intuition and insights: these are generally obtained through listening and developing to the inner voice. Thus meditation forms to be the basic key to tap these latent abilities. The intelligence can be mapped through tests and quizzes and is valuable at each level to stimulate insights and creativity. As per some people, inner intelligence, is considered to be the most important and best success in the world. Successful people including steve jobs have stated that their super revolutionary ideas and business acumen came through their intuition.
 Meditation helps in improving both short and long term memory: the key memory areas hippocampus and frontal lobe show increase in activity during meditation. By stimulating these areas, the short and long term memories are improved.

Can Yoga Improve Your IQ?

Depression is a very unfortunate state to be in, in every sense of the word. It is a sickness of the mind and can only be felt by the person experiencing it. As a matter of fact, it is even worse when depression does not occur on its own, but is rather accompanied by another condition such as fatigue.

There are many cases where depression occurs along with chronic fatigue syndrome. The irony is that when a person is depressed, he or she is unlikely to be willing to get out of bed and when this is compounded by chronic fatigue syndrome, even if the depression alleviates, it would not make much of a difference as it would be a case of  mind willing, flesh weak !

Many of the people who are diagnosed with depression have extreme patterns when it comes to sleep. Either he or she would sleep for extended periods of time and feel lethargic to do anything else. Or, the other situation is generally when he or she is more or less an insomniac and does not get sleep even if he or she would really like to grab a bit of shut-eye!

What are the Symptoms?
When a person is going through depression, it can be said to be of the highest importance to be able to judge the symptoms of the condition soon, so that the person can go and seek treatment. The symptoms, which are being talked about include extreme eating habits, that is, either eating way too much or not enough at all, along with a continuous sense of anxiety which, depending on how severe the case of depression is, can cause a person to have his or her mind clouded by the anxiety which over sweeps all other thoughts. In addition to these symptoms, there are other signs which appear with the onset and continuance of depression. These include disinterest in hobbies, which once appeared enjoyable to take part in.

Chronic fatigue syndrome kills off any urge to partake in any activity, which is voluntary in nature. With the combination of these two conditions, it can be quite possible, rather unfortunately, for a person to find himself or herself to be stuck in a vicious cycle. Sleep disorders, such as sleep apnea can really kill a person s zing and as a result of the same, make it harder for him or her to get out of depression and more likely to fall into depression if he or she has not yet. Curing depression includes changes schedules, engaging in yoga and other similar activities. Dietary changes may also be warranted. However, the recovery should take effect soon!
