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?

4 Life Lessons to Learn from Kangana Ranaut

Despite being an outsider in the industry, Kangana Ranaut has made her mark in Bollywood. The 'Queen of Bollywood' bagged the National Award in the best actress category for the third time for her double act in the commercial hit Tanu Weds Manu Returns. Ranaut is one of the highest paid actresses in India and is known for playing emotionally intense roles in films like Gangster and Woh Lamhe. But behind the fame and the glory, lies a story of struggle and constant perseverance. Kangana's rise to fame did not happen overnight, and her travails and triumphs have quite a few important lessons stored for all of us.

Here are 4 inspiring life lessons to take away from Kangana's real life story.

1. Be Yourself

Accept yourself and embrace the person you are. Making desperate attempts to fit in a social circle or trying to make people like you could turn depressing. Be yourself and don't compromise on your identity and be afraid to have a mind of your own. Kangana has constantly inspired us to be rebellious and to question stereotypes and sexism.

'People in the industry treated me like I didn't deserve to be spoken to and I was some unwanted object. I couldn't speak English fluently and people made fun of me for that. So dealing with rejection became a part of life...Today, when people say that I have made it and made it on my own.'

She said on an interview with Daily News and Analysis

2. Deal with your relationship problems

Stop tolerating abuse. Your partner is supposed to love and support you and not hurt you physically or emotionally. Don't be afraid of getting out of a relationship. It might be difficult and hard to deal with but it's best to get over with and start afresh. Ranaut was in a relationship with Aditya Pancholi, which turned sour after he assaulted her. Later she was also in a relationship with Adhyayan Suman and Nicholas Lafferty, an English doctor, which did not last either, but she always moved on with her head held high, personifying dignity.

3. Beat the odds

There might situations when your family does not support your career choices but don't let that stop you from going ahead with it. Believe in yourself and work hard on your goals. Kangana Ranaut inspires us to not give up easily. In spite of being an industry outsider, Ranaut made her mark with remarkable performances in Fashion, Queen, Woh Lamhe and Tanu Weds Manu. She quit pursuing medical and went for modeling instead and refused to take financial aid from her father. In short, don't give up on your dreams no matter how difficult it gets.

4. There is no end to learning

You can always continue with your interests even if you have a very busy professional life. Make time for your hobbies and interests as they expand your outlook. Ranaut learns Kathak as she enjoys dancing and considers it as a form of therapy. She also did a course on the technical aspects of filmmaking from New York Film Academy. She did not let her stardom affect her personal interests and wants to have a normal life.

'I don't want to lose my rights as a common person to learn and grow'

She said on an interview with Filmfare.



4 Life Lessons to Learn from Kangana Ranaut

Depression can be caused because of many reasons. However, it can get worse or be triggered due to nutritional deficiency. However nutritional deficiencies and depression act in a vicious cycle. Depressed people often receive less or improper food which leads to malnutrition which again aggravate depression. Thus, both conditions should be treated simultaneously. Read further to know how:

Omega-3 fatty acids: An Omega-3 unsaturated fat deficiency can cause depression. That shows exactly how much fish, salmon, halibut or flaxseeds and walnuts we have to expend to be at an ideal level. These basic minerals lessen aggravation and take up a basic part in our mental health, particularly memory and disposition.
Vitamin D: Vitamin D deficiency is a noteworthy problem that specialists and general physicians perceive to be dangerous. This lack has been connected to depression, dementia and mental imbalance. The majority of our Vitamin D levels drop off during the fall and winter months, since daylight is the best source of vitamin D.
Magnesium: Odds are great that you are magnesium inadequate since a lot of people are. Sugar, phosphoric acid, perpetual anxiety, anti-infection agents and diuretics contain magnesium. Magnesium is infrequently alluded to as the anxiety counteracting agent.
Vitamin B complex: B vitamins like vitamin B6 and vitamin B12 have some great medical advantages, including decreased heart diseases and healthy skin and nails. Again, a vitamin B deficiency may affect your emotional wellness. Every one in four depressed or stressed woman suffers from vitamin B12 deficiency.
Folate: Individuals with a low folate level have just a seven percent reaction to treatment with antidepressants. Those with high folate levels have a reaction of 44 percent. That is the reason a lot of specialists are currently endorsing a folate called Deplin to treat dejection.
Amino acids: Amino acids are the building blocks of protein that help your mind work efficiently. An amino acid deficiency may make you feel slow, foggy, unfocused, and discouraged. Great sources of amino acids include meat, eggs, beans, seeds, and nuts.
Iron: Iron deficiency is truly common in women. Around 20 percent of the women and 50 percent of pregnant women are iron deficient. Just 3 percent of men are iron deficient. The most widely recognized type of side effect is the decreasing number of red platelets brought on by the lack of iron. The side effects include weakness, concentration issues and a foggy mind.
Zinc: Zinc is used by more proteins (a person has more than 300) than some other minerals. It is important to most of the body s systems. It also helps our stomach to determine what food items or nutrients to keep and what to dispose off.
Therefore, it is very important for a person to consume the right amount of nutrients that a human needs. Their deficiency not only causes depression, but also many other diseases and illnesses.

Nutritional Deficiency - Can it Cause Depression?

Depression, or major depressive disorder, is a mental health condition marked by an extended sense of sadness and despair that affects how a person thinks, feels and functions. It affects the way you think and brings about changes in your physical and emotional self. In severe cases, depression makes it extremely difficult for you in carrying out your daily activities. Yes, the condition may significantly interfere with a person's daily life and may prompt thoughts of suicide. There is no instant cure for this disorder; rather it requires a more long term approach to treat this disease.
Symptoms-
The symptoms of depression are:
Feeling of emptiness and sadness.
Violent outbursts of anger.
Disturbances in sleep patterns, resulting in insomnia in few cases.
Constant tiredness and fatigue.
Constantly agitated and anxious.
Drastic changes in your appetite (usually appetite decreases).
Physical problems such as headache and back pain.
Constant feeling of worthlessness and guilt.
Recurrent thoughts of suicide and violence.
Causes-
Although scientists agree that depression is a brain disorder, the debate continues about exact causes. Many factors may contribute to the onset of depression, including genetic characteristics, changes in hormone levels, certain medical illnesses, stress, grief, or substance abuse. Any of these factors alone or in combination can bring about the specific changes in brain chemistry that lead to the many symptoms of depression, bipolar disorder and related conditions.
Treatments-
Psychological counselling and medications are the preferred treatment alternatives for depression. The medications that are used to treat depression are antidepressants and serotonin reuptake inhibitors. It is important to consult a psychologist before opting for any treatment procedure. The doctor will carry out a thorough diagnosis and then prescribe treatment accordingly.
Psychotherapy is another treatment process that is used to treat depression; this involves you talking about your condition to a doctor. It can help you find better and feasible ways to find solutions to problems and set realistic goals in life.
Electroconvulsive therapy is another mode of treatment that uses electric currents to modify the functioning of the neurotransmitters.


Symptoms and Treatments of Depression

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?

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!
