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, 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?

Alternating between being happy and sad as you go through life's ups and downs is normal, but if you're sad most of the time, it could be a sign of being depressed.  Depression takes the joy out of all your activities, and can make merely getting through a day feel overwhelming. The first step to overcoming this problem is to understand its symptoms and causes.  Not everyone experiences depression the same way, but here are a few questions that can help tell you if you are depressed or not.

Do you feel helpless?
It is common for depressed people to feel helpless and that everything around them is out of their control. As a result, the person may either stop participating in activities all together or try to control things they can't. Both situations are cyclic and lead to further depression.

Have you lost interest in daily activities?
The feeling of helplessness is one of the main reasons depressed people lose interest in activities. Another reason is that activities that were once enjoyed now do not seem interesting enough. In most cases, this leads to the person isolating himself and withdrawing from all his family and friends.

Do you often feel angry or irritated?
Depression is almost always accompanied by irritability and anger. Small annoyances that would usually be overlooked quickly, take on an inappropriate significance. This can lead to poor impulse control, substance abuse and anxiety disorder. In most cases, anger and depression are related by the person trying to take accountability for things that are out of his control and hence feeling helpless.

Is there a change in your sleep pattern?
Your sleep quality is very closely related to the way you feel. Depressed people often suffer either from insomnia or oversleeping. Depressed people can have trouble going to sleep as well as staying asleep. This can cause drowsiness and lethargy during the day. Sleep apnea is also linked with depression. As you can imagine, if this is left untreated, it will only worsen your depression.

Do you feel tired?
When the body does not get adequate sleep, you begin the day feeling tired. Thus, depressed people often feel fatigued and complain of a number of muscle and joint pains.  This is because the body has not had enough time to regenerate cells during the night. This is usually complemented by complains of persistent headache and stomach aches, both of which are emotionally connected to the way you feel.

The nature of depression is such that it lowers a person's self-esteem to the point of interfering with his ability to seek help. Hence, if you have a positive response to the above questions, it is time to address your problem before it worsens.

How To Recognize Depression In Adults

Depression is a very common emotion you might have experienced at least once during your lifetime. Depression refers to a state of mind when you are feeling low due to persistent sadness and loss of interest. But if the depression is chronic and long lasting for you, then it indicates that you are suffering from clinical depression. Under clinical depression, it is preferable that you go through a proper treatment course by a certified therapist. The Most common types of depressions are:

-Major depression

Under this type of a depression you will be depressed for most days of the week and if this condition extends for a period greater than 2 weeks, then it is a case of major depression. The most common method to treat a major depression is to talk to a mental health specialist and take medications called antidepressants (only after a prescription by a certified doctor).

-Persistent depressive disorder

This is a more severe and long lasting type of depression which is identified if you are depressed over a period longer than 2 hours. The most common symptoms of this type of a disorder are - change in your appetite, too much or too little sleep, lack of energy or fatigue, low self-esteem, trouble concentrating or making decisions, feeling hopeless among others.

-Bipolar disorder

If you are experiencing extreme ups and downs of mood abruptly and without any apparent reason, then you might be suffering from this disorder. This disorder is commonly known as a maniac depression, because during an up phase you will be extremely happy, joyful outgoing and talkative but during the low phase you will be sad, tired and depressed.

-Seasonal affective disorder

This type of a depression might bother you only during the winter season. This happens whenever the days are shorter and your body is not able to get enough of sunlight. This mostly happens in the case of people who are very fond of sunlight, and they prefer the sunshine over dark periods of the night. This disorder is treated by SAD antidepressants and everyday light therapy of 15 to 20 minutes.

-Psychotic depression

Under this type of a depression, you will have a major depression along with some psychotic symptoms like - hallucinations, delusions, and paranoia. Hallucinations mean viewing things that are not there, in reality, delusions are false beliefs or misconceptions and paranoia is the constant fear that somebody is going to harm you.



5 Types of Common Depression

Role of relationship problems in depression and suicides - 
Almost everyday we read about people ending their lives by committing suicides from celebrities to common man to even children . Although this is not permitted in any religion and there is a legal debate on whether it should be legalized, the fact remains that people are driven towards this unfortunate step. Let's take a look at the common reasons for suicides to become so very common.

1) Lack of intimacy- We see that although we are surrounded by people most of people are having friends only on Facebook. Even among the people we interact everyday nobody wants to open up with anyone or allow you to open up with them.The fact that you are surrounded by people who don't share themselves with you intimately starts pulling your mind downwards. Work colleagues are bothered only about work, family is only bothered about the income you are generating, partners are obsessed with how much you can spend on them, friends are occupied with what benefits you can share with them. Therefore all in all, despite having all relationships, people feel left out and alone like as if their inner self has been left unwanted and uncared of. The monotony of mechanical life hastens the culmination of this abuse into drastic steps like suicide.

2) High demands- People are often left to fend with high demands from them from their social circle. Many people cannot attempt this and some who attempt are not able to make it. This leaves them with a feeling of failure which is often frowned and looked down upon whether it is a student or a professional. It is no surprise that today even below 10 years olds are successfully attempting suicides.

3) Inappropriate planning- Planning is a key necessity for successful results whether it is financial or relationships. but unfortunately many people are unable to obtain the correct know how which will enable to implement their plans successfully.

4) Inability to cope- Many people plan to do things but are unable to cope with the harsh realities that come with the plans. To some it may be unseen to some unbearable. So although they set out on doing something the journey is not what they had expected.

5) Lack of results- Sometimes although everything is planned well, executed well and completed well it does not fetch us the rewards that may seem appropriate to the level of efforts. This is something that is very difficult to deal for most people and is a result of many unfortunate casualties.

6) Lack of desire-It is very important to have something to look forward to in life. But unfortunately in an age where drinking water and using the toilet cost s money many people cannot think of having something to look forward to and hence this unfortunate step.

Therefore, you have to be very prudent in what we are doing today because we can never predict which way our lives may go and even importantly which way you may yourself go based purely on circumstances beyond our control dependent on the choices we make today or others make for us. Although suicide is not a sensible solution to any problem it does remain a common reality. If you are feeling suicidal please remember to seek help.
