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?

Migraine is the most severe forms of headaches. Migraine attacks usually include nausea, vomiting, and sensitivity to light along with the severe headaches, which are sometimes unbearable. If faced with this condition, there is only one way out to suffer through it, though pain medications do help manage the pain.

Being such a common condition, there is constant research being done about how to help people deal with migraines. In addition to popping pain killers, there is more than what a person can do to reduce the pain.

Identify the triggers: Those who have had migraine for a while would know what triggers the attack. Whether it is chocolates or eggs, get to know what can induce an attack, and if possible, stay away from it.
Stick to a schedule: Whether it is in terms of food or sleep, try and develop a routine and follow it.
Physical workout: Develop an exercise regime to cover at least 30 minutes of physical exercise. Most people see a dramatic difference with a regular exercise routine.
Bid goodbye to smoking: If you are a smoker, work at quitting this habit. It is one of the known triggers and also aggravates regular headaches.
Stress management: Whether you are going through physical or emotional stress, migraine attacks can become more frequent and severe. Manage physical stress by not sitting at the same location for prolonged periods and by doing small exercises to relax the shoulders, knees, and jaws. For emotional stress, identify what helps you relax and follow it. While deep breathing works for some, for others, it could be music. Whatever your relaxation technique may be, ensure that you follow it. Work on improving relationships that stress you out. A regular exercise routine and sleep pattern also helps in reducing physical stress.
Despite these methods, migraine attacks do happen. Follow the next few steps when you know you are getting an attack.

Stop your regular activities and find a calm environment for yourself. Let this place have less of light and sound as they can aggravate migraines.
Sleep if you are able to.
Go for a warm bath if possible.
Try hot or cold compresses, which can numb the senses and reduce the pain.
Have a caffeinated beverage as this will provides relief. Do not have it in excess as you will have hangover effects from the caffeine.
Use only those medications that were prescribed by your doctor. Do not experiment.
Lifestyle changes including exercise, diet, and stress management play a vital role in dealing with migraines.

Migraine - How To Deal With It?

Cerebral ischaemia or brain ischemia is a medical condition that restricts the flow of blood to the brain, resulting in an unmet metabolic demand. This leads to limited oxygen supply in the brain, which could result in the death of brain tissues, cerebral infarction or an ischemic stroke. Thus, a cardiorespiratory arrest, a stroke, and irreversible brain damage are few possible consequences of cerebral ischaemia.

People with compressed blood vessels, low blood pressure, congenital heart defects or sickle cell anaemia have a high risk of developing cerebral ischaemia since compressed blood vessels or very low pressure can lead to restricted blood flow. Also, sickle-shaped cells have a greater tendency to clot, causing obstructed blood flow.

Patients with cerebral ischaemia experience a host of symptoms, such as weakness in the body, problems with coordination and movement, vision and speech impairment and unconsciousness.

Cerebral congestion, on the other hand, refers to the excessive quantity of blood in the brain vessels, causing pressure on the cerebral substance. Cerebral congestion is of two types. It is termed as active when there is too much arterial blood flow and passive when there is undue quantity of venous blood in the veins of the brain. Both conditions cause symptoms, such as a severe headache, insomnia, irritability and unconsciousness. The patient gets little sleep and is disturbed often followed by dreams. When awake, the patient s mental activity in the brain is very high.

Homeopathy is now a well-established school of medicine backed with years of research and practice. Gone are the days when homeopathy was considered no more than an extension of herbal home remedies.

Homeopathic laboratories around the world produce a large number of medicines covering almost all ailments. The benefits of homeopathic treatment are now well established due to its holistic approach and minimal side effects. Homeopathy is undoubtedly a ray of hope for patients with cerebral ischaemia and cerebral congestion, as it delivers a comprehensive treatment plan designed to target the signs and symptoms of the disease and address its non-occurrence.

The medications deal with mild to severe symptoms, including inflammation of the brain, headache, vomiting, insomnia, stroke/convulsions and seizures. The stramonium drug, for example, deals with seizures. Belladonna is an effective remedy for sharp shooting headaches, a common symptom of cerebral congestion. Ferrum is believed to be a valuable remedy for brain ischaemia. Few drugs deal with the symptoms of both ischaemia and congestion nux is a suitable drug for the treatment of ischaemia as well as for passive cerebral congestion. Similarly, phosphorus can be used to treat brain ischaemia and congestion. Zincum metallicum is a highly recommended drug for chronic cases of ischaemia.

The treatment is comprehensive and long term and shows substantive results. Regular follow-ups and consultation with a homeopath specialist is the key to an effective treatment.

Autism in children is a condition that is characterized by limiting social intelligence, unequal skill development across sectors, and repetitive behavioural patterns. These children may show awkwardness when dealing or speaking with people, as they seem to fail to understand what other people feel. Hence, they are unable to deal out emotional responses in kind. They themselves are very troubled, sometimes, by stimuli that are considered normal by other people, including certain visions, touches, smells and sounds.

The skill set of an autistic child forms and develops unequally. While they are not very social, they sometimes gain intense intellectual abilities in the field of math, music, chess, art and related matters which require the brain to visualize and function.

There are further ways to diagnose underlying autism in a child, and diagnosis is extremely necessary for early treatment and cure. These warning signs are-

  An autistic child will shy away from both tactile and non-tactile contact. Some children may naturally be scared of being touched by a stranger, but autistic children will not even look or smile at you when you are feeding them. They cannot maintain eye contact, and neither will they show signs of affection like small smiles or cuddles, or loving glances.

  Lack of auditory communication - This is another area of communication where an autistic child will be found lacking. Even above and beyond not responding to visual and tactile stimuli, she/he will completely forego aural communication as well. They will not respond to familiar sounds around and go even to the extent of not recognizing or being able to respond to their own name.

  If you point at things in the distance, there is a lack of communication with your child as well. These children do not have the ability to maintain a connection long enough to follow your hand and record what it is gesturing at. Either the child does not feel enough of a connection to you to actually feel your stimulus worth pursuing, or she/he does not have the power or attention span to keep following with eyes the trail your fingers have created.

  The child does not use a lot of aural communication her/himself as well too. She/he does not call out often or call you by acronyms like mother and does not make small whimpering noises like most infants do, in search for some warmth and affection.

She/he does not seem to have a natural affinity for physical touch and love and does not seem to be able to show very much love her/himself through cuddles or disappointment expressed if you get sick.

Autism is a disease that has now spread to a whole range of behavioural peculiarities, termed collectively as the Autism Spectrum Disorder. If diagnosed sufficiently early, this condition can be helped to a great extent. Make sure to monitor your child for the above signs, and contact a doctor immediately if you see cause for concern.

The Ways You Can Identify An Autistic Child!

Sleep apnea is a disorder which is characterized as interruptions in breathing when you are sleeping. These interruptions or pauses in breathing usually last for about 10 to 20 seconds and may be repeated over 100 times alongside the duration of your sleep. This condition leads to poor sleep resulting in drowsiness, fatigue and poor concentration throughout the day.

Sleep apnea can be classified as:
1. Central sleep apnea: Central sleep apnea impairs the central nervous system wherein the brain fails to control muscles which regulate breathing while you sleep.
2. Obstructive sleep apnea: This type of sleep apnea occurs when the soft tissues present in the back of the throat block the airway and thus resulting in loud snoring.

Signs and symptoms
The various signs and symptoms of sleep apnea are
1. Loud and chronic snoring during sleeping
2. Interruptions in breathing
3. Shortness of breath during sleep
4. Fatigue during the day
5. Choking and gasping during sleep
6. Extreme irritability and drowsiness
7. Experiencing headaches in the morning
8. impaired concentration and forgetfulness
9. Chronic sore throat and dry mouth
10. Depression

The various risk factors for sleep apnea are:
1. If you are overweight
2. If you are male
3. If you are over the age of 40
4. If you have a large tongue and tonsils
5. If someone in your family has sleep apnea
6. Nasal obstruction due to sinus problems

There are certain prevention measures to control sleep apnea, they are:
1. Limit smoking: Smoking may cause you to retain fluid in the throat which contributes to sleep apnea.
2. Exercise: You should exercise regularly to keep off weight as being overweight increases the chances of getting affected by sleep apnea.
3. Schedule your sleep: You should get enough sleep every day so that your body is refreshed and revitalized. Getting enough sleep, thus helps in preventing sleep apnea.

Risk Factors Associated with Sleep Apnea

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.
