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?

Brain health is essential for people of all ages. Of late MIND and DASH are two popular approaches that are leading the way dietary requirement for brain health. MIND stands for Mediterranean Intervention for Neurodegenerative Delay whereas DASH stands for Dietary Approaches to Stop Hypertension. Both the approaches argue that diet plays a crucial role in maintaining overall brain health. Here is a list of 8 diet changes that can boost the brain health without having to take any other brain supplements:

Leafy green vegetables: Leafy vegetables are tried and tested source of natural brain tonic. Vegetables such as spinach, kale, collard greens and arugula should be thoroughly washed and chopped. They can be consumed with salads, pasta, and soups.
Pulses: Pulses such as lentils, beans and peas can be consumed with salads to maintain brain health. Alternatively, they can be consumed along with burgers to give it a twist. They can also be used to make patties. A mixture of black beans, onions and peppers can be mashed along with some spices to form the main entr e of the patties.
Whole grains: A batch of brown rice, quinoa, oats or faro can be prepared and consumed to upgrade brain health. While grains comprises of fibre and makes for a very fulfilling meal. Whole grain can be prepared in batches so that it can be consumed throughout the week along with salad and soup.
Home-made snacks: A snack made from walnuts, pumpkin, almonds and pistachios can serve as a quick snack during long drives and small breaks in between meetings. A small portion of these snacks will not only boost brain health but give a sense of fulfilment.
Berries: Frozen berries are known to be extremely beneficial for brain health. They can be mixed with smoothies and consumed during breakfast and or in the form of snacks. Berries are a nice addition to oatmeal as well.
Olive oil: the butter or the refine oil can be traded with olive oil while preparing vegetables and meats. It can also be used as a base for homemade vinaigrettes. Olive oil serves the purpose of good health and has hardly any side effect on the body.
Poultry items: One can become a lot creative when it comes to consuming poultry items. Chicken breasts for instance, when cooked with garlic and onion in a pressure cooker, can be a real agent for brain maintaining brain health. One can add some flavour and consume it along with sandwiches and salads.
Fish: One fish should be consumed once in every week. Salmon fish is known to have a great effect on mental health.

8 Diet Changes That Can Boost Your Brain Health

What is schizophrenia?
We all know it as a debilitating mental illness that plagues people across the globe. Schizophrenic patients often feel like they are being overtaken by situations and events that are beyond their control. They may complain of seeing people who are not there or hearing voices where there are none. This happens because the neurotransmitters in the brain of the patient do not function appropriately. There are various types, causes and symptoms of this disease. Read up to know more.

Symptoms: psychotic symptoms like delusion are common in patients suffering from this disease. Also, the patient may be severely blunted in the emotional sense, and may bear a lost look and wear a feeling of loss or absence at all times. The thought process or cognition of the patient may also suffer in such cases. Poor concentration and lack of coordination are some symptoms of this kind of suffering. Hallucinations and distorted thought processes also characterise the patient to a great extent. The patient may also display certain typical symptoms like social withdrawal, extreme apathy, and lack of motivation. The patient will also be in an emotionally numb state once the delusions have lessened.

Causes: so what causes schizophrenia, really? while no tests or conclusive examinations exist to pin point the exact diagnosis or cause of the disease, there are many factors that can contribute to the development and progression of the same. Hereditary factors play up in many cases while chemical imbalances in the brain also lead to this condition. The serotonin levels and the functioning of the neurotransmitters are the most significant causes of this disease, in such cases. Excessive abuse of drugs like lsd and cannabis can also contribute to this condition, while family relations and a dysfunctional environment can also lead to this disease.

Types: there are many different kinds of schizophrenia. One of them is paranoid schizophrenia, which makes the patient highly suspicious. Disorganised schizophrenia can lead to incoherence in speech and thought. Catatonic schizophrenia can cause social withdrawal while residual schizophrenia can lead to a complete lack of motivation. Finally, schizoaffective disorder can lead to major mood swings.

The various kinds of schizophrenia are characterised by varying degrees of mood swings, depression, paranoia and delusional thinking. The progression of the disease can be checked with the help of cognitive behavioural therapy, which can help in reprogramming the brain of the patient to a great degree. Rehabilitation programs as well as case management can help in the long run. But the key here is to recognise the symptoms early on and get the treatment or counselling started to reduce the symptoms and their spread.

Schizophrenia: Types, Causes and Symptoms

In order to determine whether a person is having a drug problem, there are several signs, which can be interpreted to know about the exact drug abuse state of a person. Drug abuse requires immediate attention before it becomes more problematic. There are several patterns and stages of drug use that have been listed below:

1. Hard drug use: Heroin, cocaine and methamphetamine fall under the category of hard drugs and are the most dangerous drugs. There are severe effects on the health and behavior of a user of hard drugs. Some people use these kinds of drugs for recreational purposes, but some can get addicted just after using them once. Such people usually isolate themselves from society and possess a high-risk behavior.

2. Frequent drug use: Frequency alone cannot determine whether a person is addicted to a certain drug. Some people may take drugs only once and twice a week, but still suffer from acute addiction. Frequency of drug use may indicate tolerance and a person may require more with each day. Frequent drug users usually keep on continuing the habit and it is hard for them to quit.

3. Early drug use: Some people start taking drugs at an early age during adolescence, and they are likely to develop severe drug problems later in life. People who take drugs before the age of fifteen turn out to be addicts as they grow up. The earlier a person uses drugs, the earlier he becomes addicted. Early drug use is a common phenomenon in today's world.

4. Solitary drug use: Using drugs and addictive substances while a person is alone may result in fatal addiction and various problems in life. Teenagers using alcohol, marijuana and cigarettes are prone to serious drug problems during adulthood. Solitary drug users are usually poor in studies and have a violent or abusive behavior.

5. Escapist drug use: Many people use drugs for dealing with stress, several problems in life or for building self esteem. These are used as a substitute for escapism, which allows a person to escape from reality to a place where nothing bothers them and they can be at peace. Such people are likely to develop drug problems. Some people may experiment with drugs just for the sake of trying, but slowly they may like it and get addicted. This causes several problems in life, and a drug problem arises. Such drug problems may affect the health in many severe ways.

Drugs are used in several patterns. All people do not use drugs in the same pattern and frequency. The pattern of drug use by a person lets the doctor determine the level of drug abuse he is on, or if he is addicted.

Patterns of Drug Abuse

Parkinson s disease usually develops at a very slow rate and the early signs of this disease often go unnoticed. As the condition progresses, the symptoms become more prominent. Parkinson s disease affects the nervous system and cannot be completely cured. However, with proper treatment, its rate of progression can be slowed and this condition can be managed. The earlier a diagnosis is made, the more effective treatment will be. Thus, it is important to be able to recognize the signs the symptoms of this disease.

The signs and symptoms of Parkinson s disease vary from person to person. In most cases, symptoms begin on one side of the body and are worse on that side even after it begins to be noticed on the other side. These symptoms can include:

Tremors
Involuntary shaking of a part of the body is usually the first sign of Parkinson s the hands are most affected by this symptom. These tremors can be felt while performing an activity or even when the hand is at rest. In some cases, it can even keep a person from performing normal tasks such as writing. Tremors caused by Parkinson s can also take the form of an uncontrollable back and forth rubbing movement between the thumb and forefinger.

Slow Movements
This is also known as bradykinesia. As the disease progresses, it can slow down movement and reduce the person s ability to move. Simple tasks such as walking can become more difficult and take much longer. The person s steps may become shorter and they may also drag their feet as they walk. Parkinson s patients may also find it difficult to get in and out of chairs.

Rigidity
Parkinson s can make muscles stiff and difficult to move. This can affect the muscles of any part of the body. This rigidity can limit the person s range of movement and make moving the affected muscles very painful.

Loss of certain movements
In addition to muscle rigidity, the person may not be able to make certain movements that we take for granted. For example, he or she may not be able to blink or smile. Swinging the arms while walking may also become more difficult.

Changes to speech
Parkinson s can make a person speak slower and reduce his or her natural volume. The person s speech may also sound slurred. In addition, they may find it difficult to speak with inflections due to which their speech may appear to be monotonic.

Imbalance
Parkinson s may affect a person s posture and balance. In many cases, Parkinson s patients develop a stoop. The loss of balance can make climbing stairs difficult and cause them to fall easily.

Parkinson's Disease - Signs And Symptoms You Should Know About It!

Schizophrenia is a mental disorder which is characterized by disturbed mental thoughts in the patient, paranoia, phobias, hallucination, slow dementia and etc. As it is clear from this brief definition, Schizophrenia is a serious mental illness which can leave a patient stranded from performing basic day-to-day activities or even keeping healthy relationships with their close ones. 

Even though there is no particular age where people are vulnerable from suffering from this disease, yet from a common observation and study conducted on the patients, it has been observed that schizophrenia hit men in their early 20 s and early 30 s in case of women. The study also feels that it is impossible for a schizophrenic to be of age younger than 12 or older than 40. According to another study conducted by the universities, the life of a schizophrenic patient is not guaranteed. 

Symptoms of Schizophrenia:

As mentioned above, there is a common pattern in each schizophrenic patient, however, it is next to impossible to diagnose schizophrenia in teenagers since the onset of the disease is symbolized by the patient's constant change of friends or decrease of performance in school, both of which is normal in teen years. Schizophrenics also isolate themselves and become moody which again, is a common instinct of the teenager. However, apart from these, there are other differentiating symptoms as mentioned below which help in the accurate diagnosis of the disease. 

Hallucinating
Delusional
Emotionally dull and disconnected with their loved ones
Negative social life and academic performance
Dementia
Disability of remembering easy-to-learn and remember things
Causes of Schizophrnia

According to the researchers, there are more than one reasons for this disease. Read them all below:

Genetic mutation and inheritance- genetics play an important role in this disease. It needs more than one mutational combination of schizophrenia to happen and that is why it is observed in less than 1% of the population only. Those who have had a family history of schizophrenia are very hard to inherit the disease because patients hardly ever reach the stage of life called marriage. But a family history of psychosis is sure a determining factor. 
Neurotic reason- this reason includes the brain chemistry and important brain chemical such as- dopamine and glutamate.
Drug abuse- it has been revealed that consuming hallucinating and mind-altering drugs during teenage years are greatly responsible for the increase in the number of schizophrenia cases in early 20 s.
Treatment

As it was mentioned above, there is absolutely no way to cure schizophrenia known to man as of yet. However, the only way to approach it medically is by managing its symptoms separately. Such as:

Antipsychotic medication
Psychotherapies Self-help groups
Nursing care
