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?

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.

Cure insomnia with natural remedies


Insomnia is the situation where someone is unable to sleep, despite being tired or having had a tough day. It also applies when a person can fall asleep but is unable to stay asleep for long. Sleep apnea, chronic pain, indigestion, stress, medications, hormones, depression, chronic pain and restless leg syndrome are few of the symptoms of insomnia. Insomnia has become quite common and increasing ever so rapidly with our daily stressful lifestyle. There are some simple ways to combat insomnia:

1. Make Sleep a habit : 
There is a general practice to cut the sleep short whenever we go behind the schedule. Be it sitting for an important examination or preparing for a challenging assignment. It is always the sleep whom we sacrifice. This is a very bad practice. We need to remember that adults needs eight to ten hours of sleep for proper mental functioning. So make sleep a habit , try to follow a simple routine. It will help you establishing  regular sleep-wake cycles which will in long run prevent insomnia.

2. Add amino acids to diet: 
Include in your diet, foods that are high in the amino acid called tryptophan because they help calm the nerve. Chicken, tuna and turkey are such types of foods.

3.Drink hot milk: 
It has been an age-old custom to have a glass of warm milk before going to sleep. So, If you are not allergic to dairy products, you can drink a glass of milk before bedtime. It has sedative effect due to presence of tryptophan.

4. Avoid caffeine after noon and Limit alcohol and nicotine intake:
Avoid Coffee, alcohol and food with high fat content and foods which can cause allergies, at least a few hours before your bedtime. Drinking water or coconut water, after drinking alcohol is advisable. This increases the hydration level in the body and helps you sleep. You should also avoid nicotine  which is also a stimulant thus adversely affects normal sleep.

5. Pick magnesium rich foods: 
Foods which are high in magnesium are known to relax our system. Foods like oats, leafy vegetables, sunflower seeds and sesame can be included in your diet for best results against insomnia.

6. Stay away from your phone at bedtime:
It has been postulated that the blue wavelengths produced by your smartphone and other gadgets (and energy-efficient LED light bulbs) significantly suppress the production of melatonin, the hormone that makes you sleepy, according to University of Basel research. So it is better avoiding surfing the phone at bed. You have enough time with it during the whole day. Is not it? Let her sleep too.

7. Practice yoga:
Practice 15 minutes of simple, yoga-like poses (such as neck rolls, shoulder rolls, and arm and back stretches) to help your muscles unwind before hitting the bed. But you should go slowly. “The goal is to loosen your muscles to prepare your body for a good night’s sleep, not increase your heart rate,” 

8. Try aromatherapy:
Studies have shown that aromatherapy aids in sleep. Lavender oil is most commonly used, It's also an inexpensive, nontoxic way to slip into a peaceful slumber. Find a spray with real lavender and spritz it on your pillow before bedtime and it may help you go asleep better.
 
9. Adopt deep breathing exercises:
Practice deep breathing  and relaxation exercises. They are simple and can be performed lying on bed. This will help you let go stress and worries that are troubling you and will therefore calm your nerves.

10. Re-organise your bedroom:
Bedroom should be quiet and dark to have proper sleep. You can use dark window curtains which will cut the lights from outside. You can try using sleep mask. Try not to watch television for at least half an hour before bed. Make your bed comfortable with extra mattress, pillows that are not too soft or too hard. Doing these simple things will make a lot of difference in your sleep habit.

Autism Spectrum Disorder or ASD is a condition associated with brain development. ASD affects the way an individual perceives others and socializes with a group of people. This disorder shows up in early childhood; it includes repetitive and limited behaviour patterns and thus, makes it difficult for the affected child to interact or communicate with others.

The word  spectrum  in ASD refers to a range of signs related to the condition. Some children develop the symptoms of the disorder right from infancy, while others exhibit the same within 12-36 months of birth.

Signs to Watch Out for-

Early signs of Autism Spectrum Disorder in toddlers include-

  Reduced eye contact
  Lack of response (to their name)
  Difficulty learning things
  Trouble communicating
  Speaking in an abnormal tone
  Repeating words, not knowing where to place them in a sentence
  Inability to express feelings/emotions
  Inappropriate approach to social interaction   being aggressive, destructive, or passive
  Difficulty recognizing non-verbal cues
  Lack of coordination
  Oversensitive to touch, sound, or light
  Repetitive movements - spinning, rocking, hand flapping

Every child with ASD has a unique behaviour pattern.

If you notice the above traits in your child and are concerned about his/her development, then you should visit a doctor right away. A specialist can recommend an appropriate line of treatment to manage the symptoms and help your child thrive despite being autistic.

Autism and Nutrition   Is There Really a Link?

Caring for an autistic child can be challenging on many levels, and healthful eating is no exception. A child living with Autism Spectrum Disorder may not be getting enough nutrients, primarily because they are not patient enough to sit through their meals.

If your child has ASD, you should definitely reach out to a paediatrician. He/she will most likely prescribe a  special diet  to provide your child with the essential nutrients.

  Switch to a casein-free, gluten-free diet. Exclude foods such as   fishes, eggs, seafood, soy products, nuts etc. Children with ASD have an abnormally leaky gut, and these food items often cause inflammation in the gut. This further deteriorates the symptoms.
  The doctor may recommend a low-fat, high-protein ketogenic diet   cottage cheese, avocados, poultry meat, coconut oil etc.
  Serve your child a good portion of vitamin-rich foods   cereals, fruit juice, oatmeal etc. However, make sure that you are aware of any allergic reaction your child may have before incorporating these in their diet.

Health experts state that for children living with this condition, a balanced, nutritious diet can make all the difference in the world   it can improve their learning ability, help them to express themselves more and process information better.

Early Signs Of ASD In Toddlers!

The most powerful and amazing organ in our body is the brain. It differs from many other organs of our body not only by its shape, but also by its special type of cell called neurons. When these cells gets affected or dead it can never be reverted or regenerated which is the most exclusive nature found only in brain cells. The cells in other parts of our body has the capacity to regenerate (can be replaced or new one can be grown or produced), but brain cells are exception. Hence any damage to the brain, injury or trauma is really a crucial thing to be considered with utmost care.

Brain surgeries really need skill, proper training, confidence and intelligence to perform this highly complicated and risky surgery.

Purpose:
Brain surgeries are performed to:

Remove the brain tissues that are grown abnormally
Aneurysm is clipped to prevent flow of blood cliff off an aneurysm
Biopsy purpose or to remove the tumour
Make a nerve free
Drain the abnormal blood or clot collection or to drain any excessive fluid collection caused by infection.
To implant artificial electronic device as a treatment for conditions like Parkinson's disease
Types:

Biopsy: A part of brain tissue is removed for the brain or whole tumour is removed.
Craniotomy: The skull bone is opened to remove tumour, an aneurysm and drain fluid or blood from infection.
Minimally invasive endonasal endoscopic surgery: Endoscopic devices are inserted through the nose to remove the lesions or tumour.
Minimally invasive neuroendoscopy: Similar to endonasal surgery but small incision is made.
Risks:

Anaesthesia risks like breathing difficulty, allergic reaction to medications, excessive bleeding or clots and infection.
Risk related to the brain surgeries are seizures, coma, swelling of brain, infection to brain or meanings, surgical wound infection that intrudes to the brain structures, abnormal clot formation and bleeding.
General risks include muscle weakness, disturbances in memory, speech, vision, coordination, balance and other functions that are controlled by the brain.

Brain Surgery - Know The Purpose Behind It!

Whether it's a child or a grown-up, difficulty in concentrating is often experienced by many people. While, people tend to brush off this particular problem to be nothing worth being concerned about, but sometimes, there may be a more serious underlying issue for which concentration problem is only a mere symptom. Yes, difficulty in concentrating can be a sign of a neurological disorder. Keep on reading to know more about neurological disorder, its symptoms, and treatment.

Reasons behind difficulty in concentrating
Inability to focus properly is a periodic and normal occurrence for many. While sometimes it is the emotional stress or physical tiredness that is responsible for it, at times it is the outcome of hormonal changes in the body, such as during pregnancy or menopause that causes it. However, when experienced in severe degrees, it may be a characteristic of a serious psychological condition called neurological disorder. Affecting both adults and the children, the neurological disorder can be a serious threat if not treated at the right time.

Neurological disorder
Neurological disorder refers to any condition that happens due to the dysfunction of the nervous system or the parts of the brain. Depending on the location of the damage to the nerve or in the spinal column or the brain, different areas controlling the vision, movement, thinking or hearing can be severely affected. The decreased ability to focus on something or loss of concentration power being one of the many symptoms of neurological disorders among the various complications it causes.

Causes behind neurological disorder
Many reasons lead to neurological disorder or its associated symptoms like difficulty in focusing. From lifestyle-related issues to nutrition related causes, physical injuries to some infections, complications during childbirth, and genetics to environmental influences, numerous factors can be responsible for such disorder. Depending on the type of neurological disorder, the symptoms can vary from to another, while for some difficulty concentrating can be a symptom, for some, the symptoms can be more of physical difficulties such as problems in walking or difficulty speaking or seeing, etc.

Dealing with difficulty concentrating
Once the cause of the neurological disorder is determined, there are various treatment options, offered by the doctors. To deal with the neurological disorder as the cause of difficulty concentrating one may need medications and treatment provided by the medical professionals. However, there are a few tips that one can keep in mind, such as minimizing multitasking and focusing on one single thing or thought at one time or dividing tasks into small steps, etc.

Difficulty in concentrating means the ability to focus on thoughts or action decreasing. In case one experience this issue on a long term basis or excessively, visiting the neurologist as soon as possible should be the best thing to do.
