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

Neurodevelopmental disorders refer to any impairment and disorder of the brain and nervous system growth and development. Disorder in the brain and nervous system can affect the emotional, physiological, psychological ability and overall timely development of a child. With advanced technology and continuous study in the medical field, one can now assess the neurodevelopment of his/her children. Neurodevelopmental Assessment concentrates on the overall growth and development of a child including his/her weaknesses and strengths. A complete developmental profile is generated with the help of various tests and examinations. This assessment is used to analyse the various developmental factors including social and communication skills, functional and motor skills, cognition and learning abilities, and language and speech development. Neurodevelopmental Assessment involves a team of child s close people including parents, guardians, and family members who help to understand the medical history if any. It helps doctors to provide appropriate ways to assist the child in his/ her growth and development.

Tests and Examinations

Tests for the Neurodevelopmental Assessment may vary from child to child depending upon their condition. But, there are usually some tests that are done to understand the overall development of the child. These tests may include speech tests, hearing tests, blood tests, physical examinations, and questionnaires, which may be given before or during the assessment process.

Assessment

The assessment processes and sessions may vary depending upon the need of the child. However, usually, there are three major sessions that help the pediatrician understand the concerns of the family and parents. These sessions include consulting about the detailed medical history of the child, understanding the problem and its possible cause, and providing proper ways and treatment options for the patient. 

In the first session, parents and guardians are asked about any medical concern they have and the medical examination of the child is carried out accordingly. A standardized assessment with the child will be carried out by a clinical psychologist and the parents and guardians are asked to complete a questionnaire for the assessment. Depending upon the age, questionnaire may be sent to school for teacher/s to complete.

The next session is usually led by language and speech therapist to discuss and understand the current language and speech concerns of the child. Previous assessments and medical examinations are taken into account to carry out further assessments. An occupational therapist will assess the child s ability to perform self-care activities and other tasks according to his/her age. The session may include the assessment of a child s motor skills and abilities and reflection on any probable sensory-based problems that may be affecting the child s occupational performance.

The last session mainly includes the discussion with the parents and guardians to help them understand the problem, its causes, and treatment options. If the child requires any further assessment or/and recommendations, then the parents are told about that too.

Takeaway
Neurodevelopmental Assessment of children is often performed on kids who do not show the developmental signs according to their age. Parents and guardians should not hesitate to consult their children to clinical psychologist and therapist as the early intervention and assessment can help in the timely growth and development of the children.

Neurodevelopmental Assessment (0-5 Years)  - What Should You Know?

Trigeminal neuralgia is specified by the condition of a chronic pain that influences the trigeminal nerve. This nerve transfers sensation from one s face to his/her brain. If a person is suffering from trigeminal neuralgia, then a gentle stimulation of face (sourced from brushing teeth or applying makeup) might generate a fright of agonizing pain. The affected person might experience short and mild attacks initially. However, the trigeminal neuralgia might progress and generate more-frequently and longer attack of severely critical pain. Women get affected by this situation more than men get and it is more prominently occur in individuals older than 50 years.

Trigeminal neuralgia does not mandatorily mean that you need to experience a lifelong pain. Various types of treatment alternatives are available and so doctors can usually handle the particular condition effectively by taking help of injections, medications or surgery. Various types of triggers might cause the pain regarding trigeminal neuralgia, such as eating, drinking, shaving, brushing teeth, touching face, smiling, washing face etc.

Symptoms

The symptoms of trigeminal neuralgia might comprise of one or more patterns and some of these are described below:

Sequences of serious, jolting or shooting pain that might generate as an electric shock
Spontaneous pain attacks or attacks stimulated by different activities like face touching, speaking, chewing, or brushing teeth. Pain attacks last from a few moments to some minutes.
It is not a comprehensive list because Trigeminal neuralgia hosts various other symptoms as well. If a person feels facial pain, specifically recurring or prolonged pain or if the person does not get relief through the utilization over-the-counter pain relievers, then that person must consult a doctor.
How does Radiofrequency Ablation treat Trigeminal Neuralgia?
Trigeminal Neuralgia is a chronic and painful condition that involves the trigeminal nerve. There are two separate trigeminal nerves on both sides of the face, which carry the sensations like pain from the face to the body. Each nerve has three branches- forehand, midface and chin and trigeminal neuralgia can cause intense pain in any of these areas.

Causes-

This occurs when the trigeminal nerve functioning is disrupted. When the blood vessel/artery and the trigeminal nerve at the base of your brain come in contact, it puts pressure on the nerves and causes pain.
It also occurs as a result of ageing or multiple sclerosis
A disorder that damages the myelin sheath protecting the nerves can trigger pain
Sometimes pain occurs from tumors, which compresses the trigeminal nerves
Surgical strokes, facial trauma or strokes can also be the root cause of excruciating pain
Triggers-

Shaving
Touching your face
Eating and drinking
Putting on makeup
Brushing
Washing your face
Symptoms-
The pain can be mild and for a shorter duration or it can happen frequently for longer durations. Some experience the pain in cycles where it can come and go for days or even for weeks. Gradually the intensity of the pain lessens.

Cure by Radio-frequency Ablation
The treatment of trigeminal neuralgia is often a challenging process in clinical practice. When medicines do not prove as effective, surgery is the desired option.

Procedure-

After applying local anaesthesia, the Pain Specialist carefully inserts a needle through the corner of your mouth to reach the trigeminal nerve
The doctors then wake up the patient after stimulating the nerves and ask them to feel the stimulation at the same place where they undergo pain. This confirms their targeted location
Once you fall asleep again, the Pain Specialist uses radiofrequency heat to injure the nerve enough to create numbness and removes the pain
How Effective is Radio-frequency Ablation?
The pain is cured almost in 98% of the patients. 50% of patients report recurrence of pain after about two years. Hence the procedure can be repeated in the same patient if necessary.

Trigeminal Neuralgia And Radio-Frequency Ablation - What Causes It?

Surgery to remove abnormal growths of the brain, peripheral nervous system or the spine or any disorder can be tricky because the brain and the skull that shields it are complex areas. In the old days, open surgery was the only way to access the brain or spinal cord. But, with the invention of laparoscopy, keyhole surgery to treat neurological issues is gaining ground.

What is Neuroendoscopy? 
Neuroendoscopy is a surgical procedure that is favoured by doctors and patients alike because it is minimally invasive.
Before the surgery, you will be administered general anaesthesia so that you will be unconscious during the entire duration. During the surgery, the surgeon will drill a minute hole into your skull just above the eyebrows. You skull also has two natural openings. That is why the surgeon may make use of the nose or the mouth to access the region that needs to be operated upon.

Neuroendoscopy is useful because -

  It lets the surgeon reach regions that are not accessible with open surgery
  The tumour can be removed without any damage being done to surrounding tissues

An endoscope is a delicate device with a high-resolution camera mounted on it. There is an eyepiece on the other end. The device is also fitted with a light. When it is inserted into the brain, it lights up the passage and the eyepiece allows the surgeon to take a look inside. The camera sends a live feed of the path it is traversing and this guides the surgeon. When the tumour is reached, it is gently removed with other surgical instruments that too were inserted through the cavities or the drilled hole.

Benefits of Neuroscopy -
There are several advantages of relying on laparoscopy -

  The patient endures less pain
  Fewer chances of infection
  Faster recovery
  Very little scarring of tissues

Which Disorders call for Neuroendoscopy?
Any of the following disorders can be put to rights with a neuroendoscopic surgery -

  Pituitary tumours
  Rathke s cleft cysts
  Pineal area tumours
  Ventricular tumours
  Skull base tumours
  Brain inflammation triggered by an infection
  Chordomas
  Cerebrospinal fluid fistulas
  Trigeminal neuralgia
  Cerebral aneurysm

After Surgery-
Once you undergo the neuroendoscopic surgery, you will have to be rehabilitated so that your condition can be monitored round the clock. Neuroendoscopy is a state of the art clean and efficient surgery that is beneficial to both surgeons as well as the patients.

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.
