The relationship between intelligence and brain size, both among people and between various species, has never been precisely well defined. People often believe that their outstanding psychological capacities must mean that they are superior to all animals as far as brain size is concerned. However, it is not true since whales and elephants have much bigger brains than humans and humans have the same brain-to-body mass proportion as mice do.

Here are a number of ways by which the brain size can be determined:

Encephalization remainder: Since it would be against human instinct to admit loss and defeat, researchers have created a measure to determine the brain size called the encephalization remainder. It is the proportion of actual brain mass with respect to the anticipated cerebrum mass for the animal s size (based on the suspicion that bigger animals require somewhat less brain matter with respect to their size, compared to little animals). By this metric, human beings prove to be the best, with an EQ of 7.5 outperforming the dolphin's 5.3 and the mouse's 0.5.
IQ testing: Without a solitary and evident method for measuring intelligence, some improved tests like IQ (Intelligence Quotient) are by and large acknowledged as a moderately decent working device. IQ estimations are not without issues, and there is a great deal of criticism about their significance. IQ testing uses government sanctioned tests, for example, the WAIS III (Wechsler Adult Intelligence Scale). The normal IQ is somewhere around 90 and 110. The scores beneath the normal may demonstrate changing degrees of pathology, for example, marginal intellectual function, or mental hindrance of different severity. Over the normal range is regularly connected with knowledge, splendour, talent, or genius. However, as with computers of a few eras, size and intellect do not precisely relate. Present day portable computers weighing around one or two kilogrammes can store more data and perform a greater number of assignments than supercomputers from the 1980s that used to possess expansive structures. This is a contrast amongst quantity and quality. Numerous scientists now hold the view that it is not the whole brain, which is bigger in a human with a higher IQ, yet rather certain zones that are denser and might be bigger. A fascinating late revelation is that these ranges can be expanded in size and enhanced in usefulness during the course of our life.
NeuroplasticityIt refers to the dynamic procedure of repair and maintenance that our brains are continually experiencing. We are conceived with around hundred billion neurones, yet lose around two hundred thousand a day to a procedure called pruning. As we develop and grow, pathways in the brain that are not required are detached, and the neurones pass on. However, in a compensatory procedure, new neurones are delivered and more detailed associations are built up between neurones that are more dynamic. This is the procedure of de-cluttering, in which our brains develop to work at most extreme effectiveness. If you wish to discuss about any specific problem, you can consult a Neurologist.

Brain Size - How It Is Related With Intelligence?

A migraine is one of the worst form of headache. It is reported that over 90 percent of people who suffers from a migraine are unable to work. The intense pain totally makes them vulnerable. A mammoth 113 million workdays are wasted globally due to this problem. This being said, if the pain is slowly starting to set in, it is possible to manage it at the workspace.

Here is a convenient guide to do just that:

1. Pain Medication: If you are a migraine patient, it is likely that you have your migraine medication with you. The first step is to try the medication. If on the other hand, the medication is not available basic painkillers can be given a shot to manage the pain. Basic pain medications, such as ibuprofen are easily available over the counter and are capable of providing temporary relief.

2. Educate co-workers: Despite awareness about migraine pain, many organisations continue to turn a deaf ear about the problem. Instead of fighting with the whole organisations, it makes sense to educate your immediate colleague about a migraine. All you require is 1-2 people who have your back.

3. Control the environment: With the onset of the pain, it becomes more and more difficult to resume work. Few environmental changes such as adjusting the monitor to the eye level, using a sachet of odour neutralizer and switching off the nearest light will help you to manage the pain for few hours.

4. Staying hydrated: Migraine tends to increase multifold if the body is not hydrated. It is, therefore, essential to drink as much water as you can. Apart from the water, a few other drinks such as lime juice and green tea can be of great assistance to hold the pain back for quite some time. The best time to drink green tea is in the morning as it helps in improving mental alertness.



5. Small snacks: Although eating during a migraine can be tough because of the buzzing pain it is a good idea to have small snacks throughout the working hours. An empty stomach creates acidity and further aggravates the pain. Small time snacks such cookies and chocolate bar can come really handy at this time.

6. Get enough air: A centralized workplace can be claustrophobic and intensify the pain for many. Get out of the workspace to get some fresh air. A sudden gush of oxygen can be a welcome relief from the monotonous and crowded office floor.

7. Apply water on the skull: While this might sound like a crazy idea, applying a small amount of water in the middle of the skull can give temporary relief from the throbbing effect of a migraine. If ice is available in the office pantry, make no hesitation in applying it on the migraine side of the forehead. Ice is capable of spreading a cooling effect throughout the forehead and the skull. If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.

Migraine - 7 Ways You Can Deal With at Workplace

Firstly, what you need to realise is that Alzheimer s is not dementia and the main point you need to remember about the difference between the two is that the former is a disease while the latter is a syndrome. Alzheimer s is a neurodegenerative disease, it breaks down the cognitive functions of the brain and reduces a person s ability to function properly. It s one of the foremost reasons for untimely senility in middle-aged to old-aged persons.

It can be a scary time for the patient themselves as well as for friends and family alike but fear not, there are ways to reduce the chances of suffering from this painful predicament. Here are a few easy hacks to keep in mind to stave off the risk of Alzheimer s:

Fix your diet: Cut down on saturated fats and construct a diet combining lots of healthy vitamin and mineral rich foods, fruits and vegetables. Vitamin E is essential as well as vitamin B12 which can also be taken in the form of supplements. Vitamin E can be found in foods like spinach and even nuts. Rush University Medical Centre in Chicago has, after a lot of research, developed the MIND and DASH diets. The Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet collates portions of the DASH (Dietary Approaches to Stop Hypertension) diet to create the perfect combination that has been shown to reduce the risk of Alzheimer s by 53 percent.
Exercise mental and physical: A sedentary lifestyle is one of the major causes of Alzheimer s because it leads to slower brain activity and an overall unhealthy lifestyle. To break out of this you need to regularly exercise and not just physical exercises but also mental exercises such as solving mental maths and crosswords and reading books and newspapers. There are a lot of apps concerning games that help boost brain activity on the market that can help as well. Physical exercise can include swimming, brisk walking, joking and even gardening.
Reduce stress: Stress proves to be a huge issue for the brain contributing to its damage by putting a lot of pressure on it. Try to relax more by improving your sleep cycle, resting as and when required, and not overworking yourself.
Aromatherapy: Essential oils have been shown to work wonders, by reducing stress and relaxing the mind. Lavender, rosemary, lemon and even orange are some great options you can try out. These oils can help rejuvenate damaged brain and nerve cells.
Meditation: Studies have shown that regular meditation helps boost grey matter in the brain, and along with yoga, keeps the minds and bodies of middle-aged people active and better focused contributing to the overall health of the brain.

Life Hacks! How To Beat Alzheimer's

If you are being treated for Parkinson's disease. How can you maximize the effect of Levodopa? The effect of levodopa can be maximized by increasing its absorption from the digestive system. In particular, taking levodopa on an empty stomach is very important. 

Take on an empty stomach: Do not eat anything 1 hour before taking levodopa. Do not eat anything for at least 30 minutes and if possible 1 hour after taking it. Take the pill with 2 glasses of water so that it can dissolve. If taking the levodopa on an empty stomach makes you nauseous, confirm that your medication has the right amount of carbidopa in relation to the levodopa (25%). If you continue to feel nauseous, you can eat a piece of white bread around the time that you take levodopa. Do not apply any butter, yogurt, cheese or similar high protein spreads. Protein can drastically decrease the absorption of levodopa. 
Get your constipation treated: This is critically important too. Being constipated can slow down the passage of levodopa through the digestive system. In most patients, drinking adequate water and taking stool softeners is helpful. 
Get your ulcer treated: It can be difficult to recognize that you have a gastric ulcer. However, if you have a burning sensation in your stomach at any time, or belch frequently, you may have a gastric ulcer. If you think you have an ulcer you should get tested (there is a simple breath test now) and treated with antibiotics (not antacids!) 
Do not take levodopa with iron tablets: The iron binds to levodopa and prevents its absorption. Keep a gap of at least two hours between these two medications. 
Try taking levodopa with orange juice and carbonated water (soda): Mix equal quantities of orange juice and carbonated water (soda). Take your regular levodopa with a glass of this preparation instead of water. The carbonated water hastens disintegration of the tablet, and the acidity of both things helps in levodopa absorption. There are special tablets of levodopa (dispersible levodopa, Madopar) which can be dissolved in this preparation. Talk to your doctor about it.

Obesity is the new-age lifestyle disease with multiple ramifications. While its effects on the physical aspects are very evident, the damage it does to the brain are more severe, though not obvious. Read on to know some harmful effects of obesity on the emotional well-being.

Leads to binge eating: There is a certain pleasure in eating sugary and fatty food, and this is lost with depression. Therefore, to get that emotional satisfaction, people tend to eat more chocolates, cookies, milkshakes, and other weight-accumulating food items, which further add to obesity. Greater the weight gained by a person, lesser the response or happiness from such food products.
Increases impulsivity: The area of the brain known as orbitofrontal cortex, which is in charge of controlling impulsivity, shrinks in obese people. This results in people eating more impulsively.
Affects immunity: Obesity is a major cause of inflammation, leading to damage in certain parts of the brain. This impairs the immune system, making the affected person more prone to infections and tissue damage. This leads to increased chances of diabetes, heart disease, stroke, sleeping disorders, eating disorders, etc. The chemical known as C-reactive protein increases as seen on MRIs in obese people, and which is usually seen in patients with chronically increased inflammation.
Effects on memory: As the BMI increases, there is a decrease in scores of memory tests. This effect is more obvious in women after menopause. With increased fat accumulation, more hormones are released, which affects the memory. Increased inflammation also affects cognition and memory.
Increased risk of dementia: With more belly fat accumulating, there is extra stress on the body to burn the visceral fat. This reduces brain size and causes certain hormones to release, which further affects the body s ability to remember things. It has been proven that people with smaller brain size are at greater risk for developing dementia.
Weight loss stress adding to more stress: When obesity sets in and the BMI goes up, there is an added pressure to lose weight, which further ups the stress levels. During these dieting days, the brain is constantly alert and finds ways to eat more. This also leads to excess eating. Moreover, there are indications that there could be genetic changes during this phase, which may leave a permanent mark in the person s composition.
Depression: When a person is not happy with their reflection in the mirror, the chances of feeling good and happy are very less. In this age, where aesthetics plays a major morale booster, an obese image staring back does not help at all.
So, if you have a risk of obesity, watch out. It is not just how you look, but how you feel is also altered.

Obesity - How It Affects The Human Brain?

Alzheimer's disease is a neurological problem that is characterised by a cognitive decline and memory loss. It is a type of neurodegenerative dementia. The symptoms of alzheimer's disease include not being able to absorb and retain new information, lack of reasoning and judging, not being able to take on complex tasks, impaired visuospatial abilities, problems in reading, writing and speech, among many others. If a person has at least two of these symptoms in a debilitating manner, then the diagnosis can be made in favour of alzheimer's disease. The main causes of alzheimer's are shrinkage of the brain size and death of the brain cells. The immune system is also said to trigger this neurodegenerative disease. Let us find out what medical science has found so far.

1. Connections: many a times, in alzheimer's disease, the memory and behaviour of the person changes because the brain is unable to make proper neural connections which can lead to memory loss of how a person behaved and the elements that formed the basis of the patient's cognition. Apparently, the immune system behaves in the same way within the brain and blocks the connection. This happens because there is constant communication between the brain and immune system along neurological lines, which is where the disease first emanates.

2. Inflammation: the brain is prone to inflammation or swelling that is not the normal kind. This inflammation happens as a result of the activation of the infection fighting neurotransmitters and the chemical changes that happen in the brain when an infection strikes. The inflammation usually happens in the plaques or clumps which the brain tries to protect. These clumps are made up of a protein called amyloid. The immune system is responsible for creating this inflammation in the brain of the patient.

3. Pattern recognition receptors: many of these receptors work in different manners and cooperate with each other to create a response in the brain. These prrs can be found in the brain plaques, and they develop the signs of danger which further fuels the inflammation in the brain as a matter of protection.

4. Activation of cells linked with the immune system: when the prrs begin to respond, it basically activates the immune system and the cells of the same. This is the basic reaction that causes the changes in brain which then leads to the attachment of the protein to the tissue that is diseased, in which case alzheimer's disease starts. The inflammation that we had spoken about earlier basically happens in the nervous tissue.

It is important to recognise and act on the initial signs of alzheimer's disease before it progresses beyond one's control.
