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?

Dementia refers to the progressive loss of memory in a human being. It does not refer to any particular disease. It is rather a cumulative representation of symptoms which signify that the person is losing his or her memory. Dementia occurs in seven stages. Read on to read more about them:

In the first stage, there is no cognitive decline and the person is mentally sound. There is no memory loss as well.
In the second stage, there is a very mild cognitive decline leading to normal forgetfulness that is often associated with progressing age.
In the third stage, there is a mild cognitive decline. The person has an increased forgetfulness and may find it difficult to concentrate on things.
In the fourth stage, there is moderate cognitive decline and the person starts forgetting even the most recent events. They cannot even travel alone or manage their own finances.
In the fifth stage, there is moderately severe cognitive decline. The person going through this stage often requires help even with their daily activities. People tend to forget even the most common things like phone and email passwords.
In the sixth stage, there is severe cognitive decline. This stage is also called middle dementia and there is prominent memory loss. People cannot even count from 1 to 10. Their speech becomes slurry. They also start having delusions.
In the seventh stage, there is very severe cognitive decline. This stage is also called late dementia. The psychomotor skills are also lost at this stage and the person may not even be able to walk properly.
Some of the early signs of dementia are listed below:

In the initial days of dementia, the person usually tends to get confused when it comes to choosing the right words. This makes them take much longer time to conclude their speech.
There might also be a change in the mood of the person.
Depression is also one of the early signs.

The person will have a tendency to forget even the most recent events that took place in his or her life. This means that they might remember what happened ten years before but they might not remember what they did in the morning.
Early signs also include failure to sense directions. People often tend to forget their addresses and the landmarks and thus become lost when they travel alone.
Confusion is also one of the common signs and this is directly correlated to the loss of memory because when a person cannot remember familiar faces, it leads to a lot of confusion within his own mind.
So, if you suspect that someone in your house is suffering from dementia, then you must look out for these early signs and seek medical help immediately. Early treatment can keep the condition from worsening.

Dementia - Stages and Early Signs!

What is depression?

It is a state of mind when a person feels very low, loses interest in routine daily activities, feels hopeless and helpless. Many times the person starts thinking about suicide. It is a very dangerous state and needs immediate intervention from mental health professionals.

Assessment of depression:

Anyone feeling very sad cannot be called as a" depressed" person. To confirm the depression, the person needs to undergo assessment tests by either a psychologist or a psychiatrist. A" depression test" is carried out to see the exact intensity of depression.

Symptoms of depression:

Feeling very sad all the time, continuously for more than 15 days: feeling very sad continuously for a period of 15 days or more confirms depression. But just feeling sad sometimes is not depression.

 Crying for no specific reason: a depressed person may cry without any specific reason or provocation. The internal feeling of sadness is so intense, that the person cries without a good reason.
 Feeling worthless and hopeless: a depressed person has very low self esteem. The person thinks that he/she is useless, has no value and respect in the society. A depressed person feels hopeless. He/she thinks that'this is the end of the world' and things cannot improve. The person does not have any hopes about future and may start thinking about committing suicide or may attempt suicide.
 Loss of interest in life: the person loses interest in life. Does not feel like taking part in any activities which she/he were interested in doing earlier. There is nothing to look forward to, in their life.
 Ignoring personal hygiene: the person is so disinterested in life that she/he becomes careless about personal hygiene. They may not take bath for days together, may not even change their clothes or comb their hair or brush their teeth and are least bothered about the general cleanliness.
 Sleep disorders: the depressed person may sleep all the time or may not be able to sleep at all, which affects their overall health.
 Eating disorders: the person with depressive symptoms may stop eating or eat very little or in some cases eat a lot.
 Lack of sexual desire: the person may lose interest in sex and stop interacting with the sexual partner or start avoiding them.
 Feeling like a loser all the time, not wanting to fight back: the person has no self confidence and hence loses all the faith in his/her own abilities. Does not believe that he/she can face difficult situations and also can fight back.
 Becoming antisocial: the person avoids meeting other people and does not interact with people at home.

Causes of depression:

There are various factors, which may cause depression:

Family history: a person who has a family history of depression is more likely to have depression. If any of the parents or grandparents were diagnosed with depression then the person is more susceptible to depression.

Trauma: if a person has gone through a'life changing' experience, it can cause depression. Situations, such as a sudden death of a loved one or in case of witnessing devastating natural disasters like earthquake or tsunami or a war survivor, someone who has experienced terrorist attack or when someone has suffered sexual or physical abuse etc. May cause depression.

Health issues: if a person is having terminal illness, that can cause depression as the person has to endure lot of pain and has no hopes about recovery.

Relationship problems: if a person is dissatisfied with his/her close relationships like relation with the spouse, parents, siblings or offsprings, then the person may feel like a failure and feels worthless, unwanted or betrayed.

Financial issues: a person having any financial issue like not able to get a job or loss of job, incurring heavy losses in business or unable to earn enough money to satisfy the basic needs etc. Might get depressed.

Failures in life: failure to pass an examination, failure to achieve targets/goals, failure in love affair etc. May result in depression.

Treatment for depression:

Depression may fall in the category of mild, moderate and severe. But it is very important that the person gets assessed for the severity of depression.

Assessment by a psychiatrist/psychologist/counsellor: a person needs to be assessed by either a psychiatrist or a psychologist or a counsellor, to understand the intensity of depression. These mental health professionals may assess a person by talking to him/her and if required by applying certain'depression assessment' tests.

Medication and counselling: in case of moderate to severe depression, a psychiatrist will prescribe certain medication. Along with the medicines, counselling sessions work very well. In case of mild depression, only counselling also can be helpful.

Depression is treatable: if you come across someone with depressive symptoms, kindly advise them to seek help from a counsellor, psychologist or a psychiatrist.

Depression What You Need to Know About It

A bad habit could range from smoking or drinking to knuckle breaking or nail biting. A bad habit is one that causes or is likely to cause you or the others in your life, harm. Here are eight steps that can help you break your bad habit:

Try to understand your habit: The most important thing to break a bad habit is to know it first. In case that some habit is hurting you then you certainly need to let go of it. You initially need to set your mind about bringing an end to that habit. It is also important to understand how this habit of yours is hurting you or the ones around you.
Change your thinking: Even when we get to know we have some unfortunate habit, more often than not we are not prepared to separate it since we have practised that habit since a long time and it is by all accounts intense to break that one. We have to change our reasoning about the habit and take a look at it in negative viewpoints since a thing having negative perspectives will be simpler to quit.
Begin small: In case that you have a negative behaviour pattern since quite a while then go slow to break it down in light of the fact that a bad habit is hard to separate at once. Try not to attempt to do everything at once since you would not have the capacity to do as such.
Make tiny improvements: Try not to make extreme improvements to your habit since it is your habit and it will some way or another takes its time to break. Rather make little improvements with the goal that it will not aggravate you and soon you will encounter a noteworthy change in your behaviour and afterwards you will separate the habit totally on a more lasting basis.
Change your environment: A few habits are built because of the environment we live in. The steady surrounding makes us construct that habit in a manner that it gets stronger day by day. So in case that you understand that some negative behaviour patterns have overtaken your life and are not going down, attempt to change your surroundings.
Keep a check: Simply going ahead to bring an end to any habit will not give you appropriate results. Keeping a survey helps you in checking on how much of your bad habit you have defeated and how far you are from breaking it completely.
Reward yourself: Offer yourself a reward each time you see that you have stopped behaving in a certain way, or practising a certain habit. This goes a long way in motivating the individual to strive towards that end goal of breaking the habit completely.

Want to Break a Bad Habit - 7 Steps You Must Follow!

In many cases; divorce and separation leads not only to bad blood between the parents, but also in a child alienating himself from one parent. Insulting or belittling one parent without justification or under pressure from the other parent is known as parental alienation syndrome. Parental alienation involves one parent undermining the other and interfering with the child s relationship with the other parent by limiting contact with them, bad mouthing them, forbidding discussion about them etc. This can have a very negative effect on the child s emotional state.

1. Self hatred: For children, hatred is not inborn, but developed by the situations they are in. By bad mouthing a parent and teaching the child to hate the parent, the child himself is harmed. With time, he begins to internalize this hatred and believe that there is something wrong with him that made the alienated parent not want him.

2. Low self esteem: When a child is not allowed to speak his mind and has to bottle up his thoughts, he becomes socially withdrawn. Often the child begins to feel that he is the cause for the rift in the family and makes himself responsible for the separation. This intensifies with time and makes the child lose confidence in himself leading to low self esteem.

3. Lack of trust: When a child is suddenly pulled away from one parent and told how that parent is not a  good person  the child is likely to feel betrayed. This creates a sense of doubt in the child s mind and makes it difficult for him to trust other people. As he grows up, this can affect his own adult relationships as well.

4. Depression: Depression is a commonly seen in children from broken homes and this is intensified in cases of parental alienation. It is rooted in the child s feeling unloved by either one of the parents and built up by the separation. Not being given a chance to speak about their feelings or talk about the situation makes them more depressed and they begin to withdraw into themselves. In many cases, it is noted that alienated children have strained relationships with their own children as well.

5. Substance abuse: Depression is one of the most common triggers for substance abuse. Alienated children often feels trapped and that they have no outlet to vent their feelings and frustrations. This often makes them turn towards drugs for relief and can make them victims of substance abuse.

Effects of Parental Alienation Syndrome on Children

You might be aware that the Parkinson s diseases is related to the nervous system and is a progressive disorder that impairs movement. The cause of the illness is still unknown, but certain factors like environmental triggers and genetics may play a part in this regard. There are several myths about this condition that are prevalent among people. Some of them are listed below along with the facts.

Myth #1: Parkinson s disease occurs only in aged persons
This is one of the biggest misconceptions that people have about this disease. The misconception arises because the disease is usually diagnosed at an old age. But according to various researches that are conducted the disease may start developing at a younger age.

Myth #2: The disease symptoms include only impaired movement
Impaired movement maybe one of the biggest symptoms of the diseases but not the only one. There are other symptoms which affect day-to-day activities but are still unnoticed. These symptoms include constipation, sleep disorders, sweating, abnormal bladder functioning, fatigue, sexual dysfunction, cognitive symptoms, depression and even anxiety. But the symptoms that are non-motor are treatable unlike the problems with movement.

Myth #3: There is no hope for patients who are diagnosed with the disease
Patients who are diagnosed with Parkinson s disease are often told that they do not have any hope towards a cure. It is true that the disease is a progressive one, but it is not true that it cannot be controlled. Certain devices have been discovered which when used sends a signal to the brain which helps in reducing the tremors which are one of the well-known symptoms of the disease. So, no need to lose hope.

Myth #4: Medications are the only way in which you can undertake treatment for Parkinson s disease
Some people believe that they cannot do anything except for taking medications to control the disease. But this is not true. Doing regular exercise and changing your food habits are at many times helpful in treating this particular condition. Have a balanced diet which will have enough fiber is also helpful. To increase your stability and flexibility, a daily workout routine is quite recommendable, and it will even increase your self-confidence and your feeling of independence.

Myth #5: Everything about the disease can be predicted
The disease is not at all predictable. If it were, a cure would have been in place by now. Everything from the symptoms to the treatment procedure varies from person to person. The disease may take years to develop in one individual but may develop instantly in someone else.

Don t go by hearsay evidence about a disease. Medical science has improved a lot over the years. If you have any doubt regarding your health condition reach out to your doctor and clarify them at once.
