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?

Some diseases like Bell s Palsy have a sudden onset. One moment everything is fine and the next, half your face feels paralysed. Bell s Palsy is a viral infection that causes temporary paralysis of one side of the face. The exact cause is unknown but this virus is said to be related to the herpes virus. The sudden onset of this condition can make a person believe that they have suffered a stroke and this condition can last for several months. Many people do not completely recover from this condition. A numb sensation, lack of control over the lips and eyelids, drooping of one side of the face and an inability to smile or blink are some of the symptoms of this condition.

Homeopathy has been used to treat a number of Bell s Palsy cases successfully. However, the results vary from person to person and the extent of nerve damage done. This form of treatment does not address only the visible symptoms but addresses the physical, mental and emotional health of a person as a whole. Since homeopathy has negligible side effects, it can be prescribed to children and adults alike. Some common homeopathic remedies for Bell s Palsy are:

Aconite and Causticum: Aconite is prescribed in the initial stages of this condition especially is paralysis seems to have set in after exposure to a cold draft. Patients who can benefit from aconite often also complain of a tingling sensation on the affected side of the face. On the other hand, causticum is prescribed to treat chronic cases of facial paralysis.
Hypericum: This is the most preferred homoeopathic remedy in cases of paralysis caused due to injury to a nerve. In addition to the symptoms of Bell s Palsy, the patient may also complain of tingling or numbing sensations and burning sensations on the affected side of the face.
Ignatia: Bell s Palsy can also be triggered by grief. In such cases, Ignatia has been proven to be quite effective. It also resolves excessive saliva production and frequent biting of cheeks of the tongue while talking and swallowing.
Cadmium Sulph: Bell s Palsy that develops as a result of a sudden haemorrhagic condition can be treated with Cadmium Sulph. In such cases, the patient may have a distorted face and may face difficulties swallowing food and speaking properly. He or she may also be unable to close the eye on the affected side of the face.
Bacillinum and Causticum: The medicines are prescribed in cases of Bell s Palsy triggered by the suppression of facial eruptions.


5 Natural Homeopathic Medicines For Bell's Palsy

Your mother has often yelled at you for playing video games for long hours, but obviously you haven t paid heed to it. Such is the obsession with video games that they don t let you rest unless you have championed all the levels in the virtual interface. Here is the source of all problems. Studies have revealed that video games have a direct relation to neuropsychiatric problems. As a result, many health experts across the world consider video game as a kind of health abuse.

People who play action-oriented video games are at higher risks. The more you indulge in these kinds of games, the more they are going to affect the hippocampus section of your brain. It is that part of the brain which is considered to be the centre of your nervous system, memory and emotion. Reduced hippocampus volume may make person vulnerable to multiple neuropsychiatric complications. Let us see some of the signs, which may indicate the onset of certain complications arising from an over indulgence in these games.

1. You spend hours on the computer or related gaming devices and devote lesser hours for your family and friends

2. You get agitated when someone stops you midway through the game

3. You become socially isolated and show signs of occasional mood swings

4. You are unable to keep a track of time once you start playing

5. You repeatedly neglect your studies, resulting in a dip in performance at school

Why does this happen?

All of the above signs indicate that sooner or later you might develop neurological problems. When you spend an excessive number of hours on playing and navigating through the games, the  hippocampus  portion of your brain shows signs of decreased gray matter. As a result, the volume of the hippocampus shrinks, causing severe nerve related disorders such as schizophrenia, Alzheimer s disease, dementia, depression, and overall general stress.

One of the biggest reasons behind this is a lack of self-control. Most of the video games will encourage you to steal cars, run away after a theft and kill your enemies. Moreover, if you succeed, you are rewarded. This naturally unleashes a blatant urge for the gratification of all these awkward desires in your real life too. Hence, once you are encountered with the reality, you tend to show violent behavior.

Can Playing Video Games Cause Neurological Problems?

Migraine headache is characterized by a severe headache usually affecting one side of the head. There are other symptoms along with headache like nausea/vomiting, sensitivity to light and sound. Some patients experience neurological phenomena like changes in vision, temporary loss of sensation and altered sensation, a phenomenon known as an aura (flashes of light, zigzag patterns, bright spots, tingling in the arms and the legs). Migraine headache can last for 2 to 3 days. 

Symptoms: The symptoms depend on the stage of a migraine attack. The stages of a migraine attack can be: 

Prodrome, Aura, Headache or attack, and Postdrome. 
Prodorme: One to two days prior to the migraine attack, patient may experience; 
Mood swings. 
Cravings for food. 
Increased yawning. 
Stiff neck. 
Constipation and frequent thirst and urination. 
In case of an aura (during or before a migraine), there may be visual, motor, speech, and sensory illusions and disturbances such as, 

Loss of vision. 
A strange sensation of needles pricking an arm or a leg. 
One side of the body becomes weak and numb. 
There are visual illusions such as the appearance of flashes of light, zigzag patterns, bright spots. 
There is a problem in hearing and speaking. 
In some cases, there may be a hemiplegic migraine (the limb becomes weak). 
During a Migraine Attack (lasts for 4 to 72 hours), there may be 

A throbbing pain on either one or both sides of the head 
Blurred vision, light-headedness. 
Nausea and vomiting 
Sensitivity to light and sound 
Sensitivity to touch and smell (though rare) 
In Postdrome (after a migraine), there can be 

Mood swings. 
A person may be sensitive to light and sound. 
Dizziness and weakness 
Confusion 
Extreme fatigue 
An amalgamation of environmental and genetic factors may be responsible for a migraine. Trigger varies for each patient: 

Stress and extreme physical exertion 
Obesity 
Alcohol and caffeinated drinks and beverages 
Salty and processed foods 
Altered sleeping habits 
Hormonal alterations in women (Constant fluctuation in the level of oestrogen) 
Oral contraceptives and certain vasodilators (nitroglycerin) 
Preservatives like MSG (monosodium glutamate) and Aspartame (sweetener) 
Sunshine, certain odours, travel, etc can trigger migraine. 
Treatment and Prevention: 

Medicines under supervision to abort an attack of migraine and special drugs to stop attacks. 
Lifestyle changes are helpful to decrease attacks: 
Avoid your trigger for migraine. 
Follow regular sleep -wake cycle. 
Regular exercise, meditation. 
Avoidance of alcohol, caffeine containing beverages. 
Other treatment options that can be availed from pain specialist: 
Transcutaneous supraorbital nerve stimulation 
Intramuscular stimulation. 
Botulinum toxin injection. 
Occipital nerve block.

Migraine Pain - Facts About It!

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

Depression is possibly regarded as the first sign of Alzheimer s disease. According to a research, the connection between Alzheimer s disease and depression is very interesting. It has been found that the life of people who are suffering from dementia is affected in 2 different ways. Individuals who have suffered from depression in their lives are at a greater risk of developing dementia. It has also been observed that people suffering from dementia also have depression. The health condition should be treated immediately because if it is ignored it can damage the quality of life and result in worst conditions like memory loss. Temperament, as well as behavioral changes, may precede memory problems in people with the disease.

Risk factor of dementia
The significant risk factor for dementia or common form of Alzheimer s is developing depression at a younger age. The other reasons for the link are not very clear, however, it has been speculated that the inflammation that occurs in depression is a contributing factor to the Alzheimer s disease. The risk of dementia also increases with certain proteins which spiral with depression. The common signs of Alzheimer s disease include lack of appetite, sadness, agitation, weight loss, and anxiety. People suffering from this condition are unable to tell if they are depressed, but their actions help in communicating a message. It is always better to seek the assistance of a physician as doctors can make use of tools to assess the neurological disorder.

Best way to treat patients with Alzheimer s
The best way to treat patients suffering from dementia and who are depressed is to engage them in activities. It is important that they step out and do some exercises. They should go out in the sunshine. It is necessary to engage them in activities and conversations and help them to lead a higher quality of life. Some of the symptoms of dementia and depression are alike but not all of them. The major symptoms of depression include feeling tired most of the times, feeling restless, irritable, feeling worthless/guilty, unplanned weight gain and trouble in focusing. These symptoms often occur for more than 2 weeks or longer.

Difficulties caused by Alzheimer s disease
In the case of Alzheimer s disease, it becomes very difficult for the individual to communicate, learn or remember mainly because the damage is caused to the brain. Due to the brain damage, there is a possibility of changes in the personality and moods of individuals suffering from this health condition. The quality of life is affected by depression as well as Alzheimer s disease. Hence, it is always better to treat the condition immediately. For that reason, it is very important to set up a pleasant environment around and help patients suffering from this condition by helping them do enjoyable tasks and make them feel positive about life.
