When it comes to the brain and IQ, is bigger 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!

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 connection in a normal manner. On the other hand, children and adolescents who suffer from Attention Deficit Hyperactivity Disorder or ADHD show sign 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.
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.
Neanderthal brain: 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.
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 brain 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!

Brain Size and Intelligence - Are the Two Related?

When the vocal cords suffer from the accumulation of non-cancerous and abnormal growth, these are known as vocal cord lesions. These lesions usually cause a variety of voice and speech related problems. These are also known as singer s nodules and nodes, which may be caused by pressure, stress and stretching of the vocal cords. Women between the age of 20 to 50 are more prone to this condition. Here is everything you need to know about the types, causes and treatment of these lesions.

Types: There are three kinds of vocal cord lesions, that is nodules, polyps and cysts. A vocal cord polyps may be caused on one side of the vocal cords and may also lead to many disturbances in one s voice. Another type of vocal cord lesions includes a mass of tissue that may manifest in the sac or membranes around the vocal cord. This cyst can be on the surface of the vocal cord or in the ligaments of the vocal cord. This may require surgical removal as well as voice therapy thereafter. Nodules are the third type of lesion that may form in the vocal folds. These are basically calluses that may disappear once the pressure and overuse of the vocal cords diminish.

Causes: These lesions are usually benign or non-cancerous growths that may be caused due to a variety of reasons. Screaming and overuse of vocal cords are few of the most common reasons for the eruption of such lesions. The heavy use of one s voice can cause quite a bit of trauma to the vocal cords and may lead to problems including lesions and disturbances in one s voice. Conditions like reflux and allergic reactions may also cause vocal cord lesions as a side effect.

Symptoms: From hoarseness to pain, there are a number of symptoms caused by this condition. A low pitch and difficulty while speaking are also some of the common symptoms of this condition. Patients suffering from the growth of such lesions will also find themselves making an effort in order to speak normally and to be heard. Constant throat clearing may be required as well.

Treatment: Besides giving your voice a rest and gargling warm saline water with salt, one can also have the condition checked by the doctor so as to ascertain whether or not it is a serious lesion that may require surgical removal and voice therapy. The doctor will usually prescribe medicines in order to deal with any underlying conditions that may have caused the lesions, including allergic reactions, reflux, sinusitis and other such ailments. One will also have to stop smoking so that there is less chemical pressure on the vocal cord. Finally, one will have to go through voice therapy for more serious lesions.

Vocal Cord Lesions - Causes + Treatment

Speech therapy is a very specific field of medicine where the therapists deal with speech disorders in children and adults, which may be a result of certain mental or personality disorders. These doctors can be essential when it comes to teaching a child how to articulate better and also to be more expressive of his/her feelings. Here is a look at a few of the benefits of a speech therapist in the life of a child suffering from speech impairment.

Improvement of articulation skills: Articulation refers to the movement of the mouth, lips and tongue in such a manner so as to form and pronounce a word properly. Aside from the movement of the mouth, voice modulation also falls within the purview of articulation. A child suffering from speech impairment cannot perform this activity as easily as a healthy child does. This is where a speech therapist comes into play. These specialists can ensure that the child s mouth movement and voice modulation can be in perfect harmony to form words normally.
Language skills: Some form of mental disorders severely limit the number of new words or grammar rules that a child can learn. A speech therapist can aid such children in learning the basic rules of grammar and apply these rules when they speak out. So, it is quite likely that the therapists may also act as teachers for the children and improve their overall vocabulary.
Improvement of listening skills: Difficulty in speaking can sometimes also lead to difficulty in understanding what others are saying. So, if your child has a speech impairment, it may mean that he has problems understanding what you say to him. In such a circumstance, the speech therapist can, for instance, help your child understand the difference between a question and a statement. In the long run, the listening skill will help your child comprehend you better.
Reduction of stammering: Stuttering and stammering are forms of speech impairment that many children suffer from. However, such impairments can be easily rectified by undergoing a few sessions with a speech therapist. The therapist can clear your child s speech and ensure that the stammering disappears by the time he/she grows up.
Treat certain vocal conditions: Your child may be unable to speak clearly due to an issue with his/her vocal chords. If that is the case, speech therapists can sometimes help your child with the same. Abnormal vocal resonance can also be corrected by these specialists. 

How Speech Therapy Can Help Your Child Be More Expressive?

Drug addiction is one of the social menaces and in most people, what starts off as a result of peer pressure and trying to be cool ends up affecting lives significantly. It is not just social, but also affects financial, physical, emotional, and social well-being. The small periods of happiness given by the drug is followed by months and years of torment.

The National Institute on Drug Abuse (NIDA) has identified that drug addiction causes chemical and structural changes in the brain, leading to dangerous and self-destructive behaviours. The brain s response to stimulus like pleasure, joy, happiness, and pain are altered with constant drug abuse. For instance, the neurotransmitter called dopamine, which makes one feel good, is usually produced by the brain in small amounts. However, drugs increase this level to 2 to 10 times more, making the person feel extremely high and happy. Since the body is unable to reach the highest level of happiness on its own, the dependency on these drugs to feel good increases.

Repeated use of the drugs leads to increased dependency, wherein the brain refuses to feel good without reaching those high levels of dopamine. The issue is mostly seen in teenagers and young adults but can be seen in any age group.

October 2 is recognised as National Anti-Drug Addiction Day and nationwide campaigns and drives are done to help people overcome addiction. One of the main reasons a drive this size is required is because of the social stigma attached to the problem. Most families shun away from recognising it as a problem that can be easily treated, and so the affected person is sucked deeper into the problem.

Overcoming addiction: One of the main success factors for treating addiction is for the affected person to recognise that he or she is addicted and needs to get rid of the problem.

    There are national toll-free helplines that are set up, which can guide through the whole program. This way, if required, anonymity is maintained and support for overcoming addiction is increased.
    It involves a group effort involving the affected person, family and friends, medical and clinical personnel, and counsellors in some cases.
    Cognitive behavioural therapy: The person is made conscious of the change in behaviour and the way drugs affect it. Healthier patterns to be happy and joyful are discussed.
    In most cases, the underlying reason for reaching out to drugs needs to be addressed also to prevent relapse.
    Group therapies where the person makes friends who have faced similar issues and overcome the problem. This increases their accountability and commitment to getting rid of the problem.

Drug abuse is a national social menace and needs more free admittance and management.

Do you know that all the facts you know and have heard regarding post traumatic stress disorder are not true? Post traumatic stress disorder or PTSD is a mental health condition, which occurs because of a certain traumatic past event, witnessed or experienced by an affected patient. As there are several myths about this condition, it is important for you to get your facts right regarding PTSD.

Myth: Post traumatic stress disorder only affects war veterans.
Fact: Even though PTSD is common among war veterans, the condition is capable of affecting any person. It is expected that almost 70% people of the world gets exposed to some kind of traumatic event during their lifetime, and almost 20% of them end up with this mental condition. The victims of physical abuse and sexual harassment are very likely to develop PTSD. Women are more likely to experience this condition on the basis of traumatic experiences such as rape, beatings, and interpersonal violence.

Myth: People should be able to move on in life after facing a traumatic event. Those who cannot get over and cope are weak people.
Fact: Many people who experience a traumatic event of extreme intensity go through periods of adjustment after the situation. Most people become capable of getting back to normal life after some time of therapy and treatment. However, the stress which is caused due to the trauma gravely affects a person s emotional, mental, and physical well-being. Prolonger trauma is capable of disrupting and altering a person s brain chemistry. The views, perceptions, and thinking patterns of many people change after a traumatic event. This results in PTSD.

Myth: People develop PTSD right after experiencing a traumatic life event.
Fact: The symptoms of PTSD start developing within three months of experiencing an extremely traumatic situation, but they also might not show or appear before several months, or even years in some cases. The symptoms are likely to be experienced for several years after the traumatic event. In some cases, the symptoms may subside or leave, only to reoccur again at a later stage in life. This is common in the case of victims who have experienced extreme situations of child abuse in the past.

Many people do not recognize that they are suffering from PTSD. This is because they may not relate the current symptoms they experience with the past traumatic event. In cases of domestic violence, a victim may fail to realize that his or her prolonged abuse exposure is harmful.
