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 tumor is an uncontrolled and abnormal growth of cells. A brain tumor is thus an abnormal growth and multiplication of cells in the brain. The cell growth can also be in areas adjacent to the brain. The brain tumor may

Have its origin in the brain (Primary brain tumor), or
Its origin may be in some other parts or organs of the body, which gradually spreads to the brain (Secondary/metastatic brain tumor).
Not all brain tumors are harmful and life threatening.

Brain tumors that exist as noncancerous cell growths are known as Benign brain tumors. Benign brain tumors seldom pose any threat to life.

Brain tumors that are cancerous and, thus, harmful, are known as Malignant brain tumors.

Do not neglect any brain tumors (malignant or not). It is better to be safe than to be sorry.

Types of Primary brain tumors:

Based on its cell of origin, primary brain tumors (benign as well as malignant) may be of the following types:

Meningiomas: Brain tumors that originate from the meninges (the membranes that cover the brain and the spinal cord). Meningiomas are seldom malignant.
Acoustic Neuromas: A noncancerous cell growth that has its origin in the vestibulocochlear nerve (the eighth cranial nerve). This nerve connects the brain with the inner ear.
Gliomas: Here, the tumor has its origin in the brain and the spinal cord (glial cells). This type of brain tumors, in most cases (~80%), are malignant.
Primitive Neuroectodermal Tumors (PNETs): Extremely rare, PNETs are malignant tumors that develop in the embryonic cells in the brain.
Medulloblastomas: Medulloblastomas is a malignant brain tumor that mostly affects children. It originates in the cerebellum (lower part of the brain).
Craniopharyngiomas: A benign brain tumor that has its origin near the pituitary gland (base of the brain). Craniopharyngiomas are common in children.
Probability of a secondary brain tumor are more in people who have had;

Kidney cancer
Breast cancer
Lung cancer
Colon cancer
Melanoma
Symptoms:

The symptoms of brain tumor include:

Chronic and regular headaches.
A change in the headache pattern.
Seizures.
A person may experience vision problems (Peripheral vision may be affected, double or blurred vision).
There may be difficulty in hearing.
Nausea and vomiting.
Behavioral and speech problems.
An arm or a leg may lose sensation.
A person has difficulty with balance.
Diagnosis and Treatment:
Though brain tumor can affect anyone and everyone, its chances are higher in

People who are more exposed to ionizing radiation. People having undergone a radiation therapy are equally vulnerable.
Children as well as older people.
People having a family history of brain tumors.
The diagnosis includes;

An imaging test like the MRI, CT scan and PET (Positron Emission Tomography).
Biopsy, whereby samples of the abnormal tissue is collected and examined.
Neurological examination.
Treatment:

Surgery is an effective treatment for brain tumors.
One can also opt for:

Radiations, whereby the abnormal tumor cells are destroyed using protons and x-rays (high-energy beams).
Chemotherapy: In this treatment, the tumor cells are destroyed using strong drugs (taken orally or intravenously).
Radiosurgery.
Targeted drug therapy: This treatment blocks the abnormalities that are characteristically present only in the cancer cells.

Brain Tumors: Types, Symptoms, Diagnosis, and Treatment

Staying up late at night intentionally is not insomnia. If you find it difficult to fall asleep, or cannot sleep soundly for long, then it is indeed a case of insomnia. The inability to sleep can have terrible repercussions on your physical and psychological health.

A number of reasons could cause insomnia. Understanding the causes could help you identify your sleeplessness as insomnia and seek treatment right away.

What Health Issues cause Insomnia?

Here are some health problems of both the mind and body that can keep you awake  

  Stress Chronic stress and worry born out of our tense lives is a direct cause of insomnia. Long-term anxiety, panic disorders, as well as PTSD can induce sleeplessness.

  Irregular Sleep Patterns Your body would hate it if you deviate from the Circadian Rhythm   the body clock. It regulates the functions of your body, including your sleep patterns. But if you defy your body clock by sleeping at irregular hours   suppose you are staying up late to get some extra work done, or you may have opted for a night shift, or if you are experiencing a jet lag   then you will notice that when it is finally time for you to hit the bed, sleep will be elusive.

  Depression Depression is a horrific psychological disorder that makes a person lose interest in life itself. And one of the indicators of depression is loss of sleep. It is not just depression, but also other illnesses that cause psychological turbulence such as bipolar disorder and obsessive-compulsive disorders, triggering insomnia.

  Breathing Issues Sleep apnoea is a dangerous disorder that stops your breathing multiple times every night and will wake you up every time. Yet you will possibly not even remember waking up. However, this does disturb the quality of your sleep and affects your health adversely.

  Dementia Dementia is accompanied by a gradual loss of memory. But sometimes people who are suffering from dementia display anxiety, restlessness or even aggressive behaviour when it is time for them to go to bed. This is called the sundown syndrome and it might even keep them up all night.

  Pain Pain is one of the commonest reasons for losing sleep. Pain can originate due to any number of reasons   arthritis, a sprained joint, an injury, or if you are undergoing chemotherapy or radiotherapy, then it may keep you awake at night. This is actually a vicious circle because the inability to sleep will aggravate your pain. Talk to your doctor who will prescribe the appropriate pain medication.

  Parkinson s disease This disease is another reason behind insomnia. Parkinson s disease interferes with your nerve signals and this might cause disruption in your sleep.

  Menopause When a woman inches closer to her menopause, her body reduces the production of oestrogen and progesterone. This imbalance of hormones can trigger sleep loss.

How long can you go without sleeping?

There is no data on how long a human can function without sleep. The longest someone stayed awake is 11 days. Usually, the body cannot last that long without some sound shut-eye. Your brain flushes out the waste matter its cells produce during sleep. That is why even 24 hours without sleep can make your brain sluggish and disoriented. If you stay awake for more than 48 hours at a stretch, your cognitive abilities will start failing you. Sleep is instrumental to a healthy mind and body. If you are experiencing insomnia, talk to a doctor immediately or look up some remedies.

Health Problems That Keep You Awake!

Migraine, the extreme headache that comes back to haunt its victims every chance it gets, can actually be managed with a controlled diet. Of course, medication is the solution, and so is surgery with botulinum toxin in extreme chronic cases. But let s try lifestyle changes before going for any of that.

Symptoms of Migraine:

Pain on the sides of the head is the characteristic symptoms of migraine, but there are others:

A throbbing sensation in the head.

Nausea from constant pain.

Photosensitivity.

More than the usual aversion to loud noises.

Sweating, stomachache, and diarrhea rarely come with the more common symptoms of migraines, as stated above.

Causes of Migraine:

Migraine is often genetic. Pain triggers include:

Hormonal changes, as in during menstruation or pregnancy or puberty.

Emotional disturbances like anxiety, depression, shock, or even excitement.

Poor posture that puts stress on the neck or head.

Tiredness or lack of sleep.

Side-effects of medication such as sleeping pills, some contraceptive pills, and medication for hormone replacement therapy.

External triggers like second-hand smoke, loud noises, very bright lights, lack of oxygen in a poorly ventilated room, dust, any strong smell.

Food Triggers

Foods that trigger migraines include:

Aged cheese with high tyramine: Blue cheese, cheddar, feta, mozzarella, brie, parmesan, gorgonzola, English stilton, Swiss cheese,

Alcohol: Red wine, scotch, champagne, beer, and vodka trigger migraine by dehydrating the body and/or due to the sulfite preservative in them.

Food preservatives: Nitrite or nitrate compounds in preserved foods like ham, sausages, hotdogs, bacon, pepperoni, and deli meat.

MSG: Monosodium glutamate in soy sauce or anything labeled  hydrolyzed  is a trigger.

Sourdough: Baked yeast products like bread, rolls, donuts, and cakes.

Nuts: Peanuts, peanut butter, dried fruits, and some seeds and nuts trigger migraine in not all but some people.

Smoked or Dried Fish

Tomatoes

Onions

Citrus Fruits: Like lemon, orange, grapefruit, Greek citron, etc.

Beans: Like lima, fava, pinto, snow peas, lentils, pole, and broad beans.

Caffeine: Anything more than 200mg of caffeine can trigger migraines.

Artificial sweeteners: Due to aspartame or sucralose content.

Chocolate: Due to beta-phenylethylamine

Avoiding these food items can alleviate symptoms of migraine. This is why one should avoid these foods in their diet. However, it is advisable to consult a Dietician or Nutritionist before avoiding or taking any food item.

Food Which Help to Cure Migraine

The elimination of diet tactics is not enough to manage migraines. There are foods that must be included in the diet. They are:

Salmon: For the vitamins, and omega 3 fatty acids that reduce inflammation and blood pressure.

Dark chocolate: Due to the magnesium content.

Fresh figs: Due to potassium and electrolytes. Avoid dried figs as they contain tyramine.

Shrimp: Due to astaxanthin and vitamins and minerals to help with inflammation.

Carrots: Beta-carotene helps.

Sweet potatoes: Vitamin C, niacin, pantothenic acid, phosphorus, Vitamin B group, manganese, copper, and potassium to the rescue.

Collard Greens

Kale

Quinoa

Ginger

Fresh fruits: Like bananas and apples.

Herbs: Like feverfew, butterbur.

Conclusion

Avoiding trigger foods, having migraines relieving foods, and having plenty of water along with enough sleep and some exercise can manage migraines well enough to not need medication.

All The Foods That Trigger Or Alleviate Migraine!

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?

Nerve pain or peripheral neuropathy, as it is medically known, is characterized by pain, numbness and weakness that arise out of nerve damage. This pain is usually restricted to the feet and the hands.

What are the common causes?

Diabetes is the most common cause for this condition. However, other causes, such as injuries, infections and prolonged exposure to certain toxins can also trigger nerve pain.

How can you control nerve pain?

Nerve pain can be managed and taken care of at home taking into consideration the points that have been mentioned below:

Topical Painkillers: Certain over the counter ointments and creams can help relieve nerve pain. These medications act as local anesthetics; that is they numb the area of the pain. Capsaicin, a derivative of chili peppers, is one of the major ingredients used in these medicines. Others use botanical oils as the major ingredients.

Painkillers: There are painkillers available OTC which can curb nerve pain. However, painkillers such as ibuprofen, aspirin and acetaminophen do not really work well for severe pain of the nerves.

Supplements: The lack of Vitamin B12 is considered to be a very important cause, and at times, a catalyst for nerve pain. In a case such as this, Vitamin B12 supplements or injections might be administered. Although more research needs to go into this, but certain supplements, especially gamma-linolenic and alpha-lipoic acid can help soothe nerve pain caused by diabetes.

Acupuncture: This time-honored Chinese approach is a proven alleviator of nerve pain. Acupuncture releases chemicals which numb the pain, or prevent the pain signals from travelling to the brain.

Physical Therapy and Massages: Physical Therapy can especially heal and strengthen weak muscles that can stem from acute nerve damage and pain. Though more evidence is needed, according to a few sufferers of this condition, massages can be helpful with the tremendously painful muscle spasms that can so often result from nerve pain.

Relaxation Techniques: In combination with the abovementioned approaches, relaxation techniques can go a long way in relieving debilitating neural pain. Besides being helpful with dealing and reducing a few stress phases of life which can cause nerve pain, these techniques might actually root out the actual pain itself.

Lifestyle Modifications: This one s always a winner! Eating a well-balanced diet that guarantees all nutrients in uniform amounts can never go wrong. Regular exercises for about 30-45 minutes can remedy different types of pain; nerve pain being one of them. Try and limit alcohol intake (a peg once a week won t harm one, but binge drinking can play the ultimate spoilsport and make all health plans go topsy-turvy!). Abstain from smoking or chewing tobacco as this is usually the primary contributor towards any medical condition or disorder.
