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 recognized as a mood disorder characterized by the prolonged feeling of sadness and loss of interest in otherwise regular activities. The symptoms include loss of sleep and appetite, loss of interest, persistent feeling of sadness and lowered self-esteem. These symptoms should last for a minimum of 4 weeks for the individual to be diagnosed with depression. Sometimes, at its later stages, depression can also be accompanied by suicidal tendencies.

How it can be treated?

Role of anti-depressants: Depression has become rather common in the present day scenario. The treatment varies from prescription drugs to therapy. People who have depression are usually given mood enhancers and anti-depressants. Antidepressants are medicines used to help people who have depression. With the help of these depression medications, most people can achieve significant recovery from depression. Most antidepressants are believed to work by slowing the removal of certain chemicals from the brain. These chemicals are called neurotransmitters (such as serotonin and norepinephrine). Neurotransmitters are needed for normal brain function and are involved in the control of mood and in other responses and functions, such as eating, sleep, pain, and thinking. Antidepressants help people with depression by making these natural chemicals more available to the brain. By restoring the brain s chemical balance, antidepressants help relieve the symptoms of depression. Specifically, antidepressant drugs help reduce the extreme sadness, hopelessness, and lack of interest in life that are typical in people with depression. However, these are but short-term solutions to depression and don t necessarily cure the individual completely. For the treatment to be effective, the drug intake must be combined with therapeutic techniques to solve the problem at the root level.
Therapy: Different therapeutic techniques are used to treat depression depending majorly on the individual, the cause of depression and general history and state of mind. Research suggests that client centered therapy and cognitive behavioral therapy are a good start with an average case of depression. The therapists usually incorporate several other methods based on the client s need to get maximum effect. Adlerian techniques, where individuals are made to comprehend the thoughts and emotions which influence their lifestyles and adopt a more productive and positive way of life, are rather helpful with most clients who suffer from depression.
Note
Depression is a fairly common mental health disorder today, affecting a large population. Depression must be acknowledged as a proper mood disorder and not just a passing phase. It is completely curable with proper medicine and therapeutic sessions. The individual is able to move over the feelings of unhappiness and lack of interest with proper care and acceptance from loved ones in addition to therapy and the drugs, of course.

Depression - Is it Curable?

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

The first question when you greet somebody is 'how are you' and this often refers to our state of well-being. While most answers would be great, awesome or good, we usually think of how we are doing physically. While some of us may talk about physical conditions (say things like feverish, have a cold, etc.), not many would think of talking about mental health conditions. However, mental health is very important for overall well-being. 

Can you think of someone who is severely depressed or anxious all the time and have a good physical health? Chances are very bleak, and if you consider the overall health as a mix of mental and physical balance, this is not possible. Read on to understand how important mental health is and why you should start paying more attention to it.

Improved physical health: If someone is in a stressed state, it is obvious that they would not be able to do the activities they enjoy. Being affected mentally also leads to reduced immunity and sleep disturbances, making the person prone to infections and other disorders. Stress is one of the main risk factors for chronic medical conditions like heart disease and diabetes.
Improved prognosis: Most often, doctors focus on treating the physical aspects of a person s health. However, with recent emphasis on mental health, more and more doctors are looking at wholesome measures to improve a person s health. Results show that when a person s mental health is also addressed, the physical ailments respond very well.
Improved productivity: People with unattended mental health disorders often resort to absence from work and/or school, can have financial instability, be homeless and can fall repeatedly. Being mentally healthy provides overall changed perspective of life and therefore improves productivity.
Improved personal relationships: Children of people affected with mental illness are prone to neglect, abuse, rejection, and behavioural issues. There is also social isolation, which may lead into adulthood, and these children may also have emotional health problems. Others in the close circle including spouses, siblings, parents, close friends and colleagues would be clearly affected by a person who is mentally unhealthy.
Social effects: These people are highly prone to social crimes like rape, murder, theft, violence, etc. They may not be able to afford their treatment and/or resort to these crimes to assert themselves.
Improved quality of life: Life expectancy is higher in people who are mentally healthy. Even with mild symptoms of anxiety and depression, this is reduced, and the chances of a happier, healthier life are reduced.
Whatever the effect, mental health needs to be addressed as equally as we do physical problems, using medications, counselling, or lifestyle changes.

Mental Health - 6 Reasons Why You Should Take it Seriously!
