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?

The neurones in the brain are constantly reorganising their connections both functionally and physically according to the environment, your thinking and behaviour. This ability is known as neuroplasticity. Through neuroplasticity the nerve cells of brain can compensate for injury to some parts of the brain and enable a person to recover from stroke, birth abnormalities. It is also beneficial in treating autism, ADD, learning disabilities and helps manage obsessive compulsive disorders.

Here are seven things you should know about neuroplasticity.

Change depends on the attentiveness of the brain: Neuroplasticity changes can only happen if the brain is alert and active. When the brain is active it releases neurochemicals that are necessary for the neurone connections to change. If a person is distracted to inattentive, these changes cannot happen.
The more the effort; the bigger the change: Neuroplasticity changes depend on how motivated the person is to change or learn new tasks. For this reason, when it comes to using neuroplasticity for physiotherapy, it is essential to first deal with any depression or anxiety issues the patient might be having before attempting to rehabilitate them.
It helps strengthen neural connections: Repetition of actions is one of the key elements of neuroplasticity in physiotherapy. Through this, the strength of neurone connections is strengthened to include sensory information, movement and cognitive patterns.
It improves cell to cell connections: This is crucial to a patient s rehabilitation as it increases reliability and makes a person more independent. In turn, this makes behaviour patterns more reliable.
It helps predict actions: A task can usually be broken down into a series of smaller tasks. For example, feeding oneself can be broken down into steps that begin with lifting a spoon and filling it with food to finally putting the spoon into your mouth. Hence, along with completing an action, the brain must also know what to do next. Neuroplasticity helps improve this associative flow and allows the brain to predict the next step.
Changes can be temporary or permanent: Initial changes due to neuroplasticity are temporary ad only if the brain determines the experience to be desired is this change made permanent. This is why when treating mobility issues, patients are not always able to repeat tasks in the same way.
Memory guides the learning: When making new neural connections through neuroplasticity, the brain is taught to discard unsuccessful attempts and only remember the experience of the successful attempts. From here, adjustments are made to improve the connection.

Neuroplasticity - 7 Things You Must Know About it!

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?

Cerebral palsy is the term for a group of neurological disorders that affects one s muscle movement and motor skills.

In most cases, the condition is caused due to a brain impairment that develops while the baby is still in the womb. Cerebral palsy may also occur shortly after or during birth.

Symptoms of Cerebral Palsy:

The signs and symptoms of the condition vary from one individual to another, ranging from mild to severe. The commonly observed ones in children are-

  Difficulty walking
  Difficulty holding on to objects
  Delay in developing motor skills- sitting up straight, rolling over, crawling
  Variation in the muscle tone- too stiff or too floppy
  Delay in development of speech
  Spasticity
  Lack of coordination of the muscles
  Difficulty swallowing and excessive drooling
  Functioning of only one side of the body
  Neurological ailments such as intellectual disabilities, seizures, and others

Types of Cerebral Palsy:

Cerebral palsy can occur in the following forms-

  Spastic cerebral palsy - Causes exaggerated reflexes and muscle stiffness. This is the most common type of cerebral palsy, affecting nearly 80% of the population.
  Dyskinetic cerebral palsy - Causes abnormal, involuntary movement of the legs, arms, and hands. It may also affect the movement of the tongue and face, thereby making it difficult to talk or swallow.
  Hypotonic cerebral palsy - Causes overly relaxed muscles and reduces muscle tone. The legs and arms are easily moveable and appear saggy.
  Ataxic cerebral palsy - This is the least common type. People living with this form of the condition have problems with coordination and balance.

Diagnosis and treatment of cerebral palsy

Cerebral palsy can be diagnosed with the help of the following-

  CT scan
  MRI
  Ultrasound
  Electroencephalogram

Treatment of the condition depends on its severity. Long-term treatment includes physiotherapy, medications and surgery.

  Physiotherapy and occupational therapy helps restore muscle strength and improves muscle tone. You can try stretching exercises to improve flexibility.
  Usually, the doctor prescribes medications in the form of muscle relaxants and sedatives. Muscle relaxants reduce muscle tension, helps relieve discomfort and muscle pain.
  You may need to undergo an orthopaedic surgery in case medications and therapy does not yield positive results. The surgery will aim to release tight muscles and repair bone abnormalities caused due to spasticity.

The specialist as a last resort may recommend SDR or Selective Dorsal Rhizotomy to reduce spasticity and chronic pain. This involves operating the nerves at the base of your spinal column.

There is no permanent cure for cerebral palsy. However, the condition is manageable with the help of drugs, therapy and surgery. The kind of treatment required depends on your overall condition. While some may be able to live with the condition without much assistance, others may require immediate medical intervention. Therefore, it is best to consult an orthopaedic and get help if the symptoms deteriorate over time.

Cerebral Palsy - Symptoms, Types & Treatment Of It!

Acoustic neuroma is the development of noncancerous and slow-growing tumors on the main, vestibular nerve that travels from the inner ear to the brain, connecting the two organs. They are also known as vestibular schwannoma, as it arises from Schwann cells covering the vestibular nerve. It rarely grows rapidly or attains a large enough size that can press against the brain and interfere with the vital functions of the brain. Since the tumor is benign, the patient can be assured that it won t spread to the other parts of the body; however, they can grow large enough to disrupt the normal function of the body.

The pressure from the acoustic neuroma on the main nerve can cause loss of hearing, a constant ringing in the ear and unsteadiness. As per a report published by the Acoustic Neuroma Association, 1 out of every 50,000 people suffers from this condition.

Risk factors for acoustic neuroma
Acoustic neuroma does not have quite as many risk factors. The only established risk factor for acoustic neuroma is having a parent who suffers from the rare genetic disorder neurofibromatosis 2 (NF2). However, having said that, neurofibromatosis 2 (NF2) accounts for only 5 percent of the reported cases. In most of the cases, it has been found that the tumors appear spontaneously without any indication of a family member having this disease or any medical history of the same.

The development of noncancerous tumors on the ear nerves as well as other nerves in the body is scientifically supported as a characteristic indication of neurofibromatosis 2 (NF2). Neurofibromatosis 2 (NF2) is also termed as an autosomal dominant disorder, which indicates that the mutated gene can pass from just one parent. Each of the children has a fifty-fifty chance of inheriting the disease.

However, scientists and doctors have failed to identify why specific people get these tumors. They have reached a generic conclusion about the risk factors, which may include:

Loud noises near the ear.
A parathyroid neuroma, which is a similar benign tumor of the thyroid.
A chance of exposure to low levels of radiation in the childhood.
How to diagnose the risk factors for acoustic neuroma?
If you are experiencing loss of hearing or other neurological symptoms, try to keep track of them. Later on, mention them to your doctor for a proper diagnosis. A detailed history of the symptoms will help your doctor. Your doctor will perform a hearing test to check whether you have an acoustic neuroma. Then the doctor may perform a brainstem auditory evoked response tests along with an electronystagmography to detect any changes in eye movement, caused due to the inner ear. MRI and CT scans are also quite common diagnoses methods for acoustic neuroma.

Acoustic Neuroma - What Are The Risk Factors?

Neurological disorders are the diseases of the brain and spine, and the nerves which connect the brain and spine.

Some of the most common types of Neurological disorders are:

Alzheimer s Disease (AD)

Multiple Sclerosis

Epilepsy

Migraines

Parkinson s Disease

Ayurvedic Approach of Neurological Disorders

Ayurveda is an ancient system of medicine which originated in India, having a holistic approach to focus on treating the entire being. Ayurveda treatments are based on vata, pitta, and kapha doshas, whose balance leads to harmony and whose imbalance leads to toxic accumulations inside the body. Ayurveda aims to maintain an equilibrium among the three. It has effective solutions for a number of Neurological Disorders, also called  Vatavyadhi .

Eighty types of Vatavyadhi are described in Ayurvedic texts which can be placed under four categories: Kevala vata (Vata alone), Samsarga (Vata in association with Pitta and Kapha), Avarana (due to entrapment by other Dosha/Dhatu/Mala), and Dhatu Kshaya Janya (neurodegenerative). 

Ayurvedic Treatment

Ayurveda is plant-based systems of medicine. Because of being natural and harmless, it is very popular in treating various diseases. Several herbs have excellent properties to treat panic and anxiety affecting the central nervous system. Nature s gift of herbs and minerals not only alleviates symptoms but ensures cure by regulating neural biokinesis, thus preventing recurrence, relapse, and adversity.

Ayurveda can cure a number of Neurological Disorders like migraine, sinus, Parkinson s disease, anxiety, stress, insomnia, epilepsy, hysteria, cerebral palsy, stroke, etc. For treating these Neurological Disorders Panchakarma therapy is adopted which focuses on holistic treatment for long-lasting results.

Some of the common remedies under Panchakarma therapy are:

Chamomile tea, roots of kava, passion flower, ginseng, Cannabis sativa are all prescribed for anxiety.

Valerian is used as a natural sedative and for treating insomnia and panic attacks.

Ginkgo biloba and Hypericum perforatum have neuroprotective properties and are useful in treating learning dysfunction and improving memory.

Inhaling powder of seeds of Achyranthes aspera or Prickly chaff flower relieves from stiffness and migraine.

Bark powder of Acorus calamus or Sweet flag root enhances memory by curing forgetfulness. When consumed with honey, it is beneficial for anxiety and epilepsy. Equal weights of this powder with ginger powder is recommended for facial paralysis.

Powder of Malabar nut with honey cures epilepsy.

Seed powder of Siris tree is used for treating insanity, psychosis, anxiety, and hysteria.

Coriander extract relieves vertigo and headache.

Juice of Dodder plant or Amarbel is taken in water to improve brain disorders.

Extract of branches of peepal tree cures madness.

Decoction of roots of drumstick plant is given for epilepsy and hysteria.

Velvet bean is effective in treating Parkinson s disease.

Poppy is beneficial in sleeplessness, delirium, convulsion, etc.

Decoction of leaves of guava is used to cure physical and mental deformities.

Leaves of pomegranate, when concentrated in boiling water and given in warm milk, cures fatigue and insomnia.

Leaves of pomegranate and rose petals when concentrated in boiling water and given in ghee, cure madness.

Cloves paste in water is applied on earlobes to cure migraine.

Almonds improve memory, especially when taken at an early age.

Yoga and meditation help in improving mental health by incorporating discipline and relaxation.

Take Away

For reliable cure with minimal side effects, Ayurveda is very well developed for treating many brain-related disorders with an approach of maintaining equilibrium among the three doshas and towards holistic, long-term treatment.
