Acoustic neuroma is a benign tumor that occurs in the primary nerve between the brain and the ear. The tumor progresses very slowly and can influence your balance and hearing. In certain cases, if the tumor becomes very large, then it may also impair vital functions of the body.
Symptoms-
The symptoms of acoustic neuroma tend to develop when the tumor starts to press on the nerve and its adjoining branches. The symptoms of this disorder are  
You may experience hearing loss on one side which might worsen gradually.
You may have problems in balancing yourself.
A continuous ringing sound in the ears.
Persistent dizziness.
If the tumor is large and presses on the nearby nerves, then you may experience numbness of the facial muscles.
In some cases, it may impair the vital functions of the body.
This disorder is caused by a malfunctioning gene. There is no documented reason as to why the gene malfunctions.
The treatment options for this disorder are  
Constant Monitoring: These tumors tend to grow very slowly but might spurt in some cases. In order to prevent damage to your body, they need to be monitored on a regular basis. Imaging tests are recommended on a periodic basis to determine the growth of the tumor.
Radiosurgery: Stereotactic radiosurgery is done to treat acoustic neuroma that is small in size. In this surgery, radiation is directed at the tumor without creating any incision. It is done to limit the growth of the tumor and preserve your hearing.
Surgery: The tumor can be removed by using surgical procedures. It involves administering general anesthesia, followed by removing the tumor through an incision on the skull or the inner ear. Surgery is used to remove the tumor and preserve your hearing abilities. 

Acoustic Neuroma - Everything You Need to Know

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!

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?

Study of the brain has fascinated specialists all over the globe since time immemorial. The brain being the most vital organ for survival and coordination is perhaps the most complex of them all too. This has led to a limited understanding of its working in spite of the available advanced technology. However, with the advent of techniques for diagnosis and treatment, therapeutic strategies are evolving. This is a major step towards rendering Neurosurgery safer than ever in the history of mankind.

Neurosurgery through the 20th Century-

During the beginning of the 20th century, Neurosurgery was considered as a specialty. The clinical-neurologist would draw conclusions related to lesions in the brain through neurological examination and clinical history. It enabled diagnosis of vascular lesions, spinal disorders, and brain tumors. During the second and third decades of the 20th century, vascular pathologies and brain tumors could be diagnosed indirectly through techniques like angiography, ventriculography, and pneumoencephalography. But since the operative techniques were too crude and the lack of skilled professionals were rampant, there were high rates of morbidity and mortality due to neurological conditions. Generally, after diagnosing the nature of brain lesion and its site, surgery was performed with inadequate maintenance and control of intracranial pressure and through not too sophisticated surgical instruments.

During the fifth and sixth decades of the 20th century, chemotherapy and radiation treatment came into the picture for treating malignant brain tumors, thereby reducing mortality to a good extent.

During the seventh decade of the 20th century, Computed Tomography (CT) scan provided a better understanding of the location of lesions in the brain which slightly substantiated the earlier techniques. Then, the procedures for cerebrospinal fluid diversion significantly improved management of intracranial pressure during surgery.

It was only during the last decade of the 20th century that the Neurology saw a giant progressive leap through the introduction of Magnetic Resonance Imaging (MRI) and powerful high magnification microscopes. Combined with Neuroanesthesia and Intracranial Pressure Management, this aided surgeons to work on a relaxed brain. This promoted safe removal of the brain tumor and better management of vascular lesions. Moreover, the understanding of micro-surgical anatomy improved drastically, leading to a boost in confidence levels of the micro-neurosurgeons performing the operation.

Neurosurgery in the 21st Century-

The 21st century is actually a revolutionary era that uses powerful computers in almost all the fields possible. Computer-based applications such as Neuro-imaging, Neuronavigation, Intra-operative Neuro-monitoring, and Neuro-modulation are now used in standard neurosurgical practice as a part of the routine. Extremely powerful CT scans and MRIs are used for diagnosis before surgery. The advent of nanotechnology and its application in Neurosurgery is doing great and has a promising future ahead based on the current study of scenarios. Moreover, there is a possibility of most of the Neurosurgical procedures becoming minimally invasive. Frameless Stereotaxy is another technique that helps in locating the exact position of the tumor, which further helps the neurosurgeon in navigating with great precision the very sensitive, high-risk areas of the brain. Such techniques, to a great extent, have lowered mortality and morbidity, lessened the rate of recovery, and chances of infection related to Neurosurgery.

Take Away-

A number of techniques for diagnosis and precise location of the tumor in the brain have made Neurosurgery much safer today, due to advancement in science and technology, than it ever had been in the history of mankind.

Advancements In Neurosurgery - Know How Safe It Is!

Your mother has often yelled at you for playing video games for long hours, but obviously you haven t paid heed to it. Such is the obsession with video games that they don t let you rest unless you have championed all the levels in the virtual interface. Here is the source of all problems. Studies have revealed that video games have a direct relation to neuropsychiatric problems. As a result, many health experts across the world consider video game as a kind of health abuse.

People who play action-oriented video games are at higher risks. The more you indulge in these kinds of games, the more they are going to affect the hippocampus section of your brain. It is that part of the brain which is considered to be the centre of your nervous system, memory and emotion. Reduced hippocampus volume may make person vulnerable to multiple neuropsychiatric complications. Let us see some of the signs, which may indicate the onset of certain complications arising from an over indulgence in these games.

1. You spend hours on the computer or related gaming devices and devote lesser hours for your family and friends

2. You get agitated when someone stops you midway through the game

3. You become socially isolated and show signs of occasional mood swings

4. You are unable to keep a track of time once you start playing

5. You repeatedly neglect your studies, resulting in a dip in performance at school

Why does this happen?

All of the above signs indicate that sooner or later you might develop neurological problems. When you spend an excessive number of hours on playing and navigating through the games, the  hippocampus  portion of your brain shows signs of decreased gray matter. As a result, the volume of the hippocampus shrinks, causing severe nerve related disorders such as schizophrenia, Alzheimer s disease, dementia, depression, and overall general stress.

One of the biggest reasons behind this is a lack of self-control. Most of the video games will encourage you to steal cars, run away after a theft and kill your enemies. Moreover, if you succeed, you are rewarded. This naturally unleashes a blatant urge for the gratification of all these awkward desires in your real life too. Hence, once you are encountered with the reality, you tend to show violent behavior.

Can Playing Video Games Cause Neurological Problems?

Acoustic vestibular schwannoma or the acoustic neuroma is a kind of tumour. But this tumour is benign which means it is non-cancerous. The vestibular nerve connects your ear to your brain, it is responsible for hearing and balancing. An acoustic neuroma develops on the vestibular nerve. And it can cause hearing impairment.

How does acoustic Vestibular Schwannoma occur? 
The vestibular nerve is lined with Schwann cells. Sometimes, these cells start to develop rapidly. This forms a mound on the nerve, it slowly becomes large enough to prod against the brain, and this adversely affects the actions of the brain.

What are the Symptoms?
In the early phases, the tumour does not trigger any symptoms. They begin to manifest once the tumour starts expanding. Here is a list of the symptoms of acoustic vestibular schwannoma-
  Gradual hearing loss
  Misalignment and losing balance
  Ringing in the ears.
  Regions of numbness in your face
Even though these tumours are benign, sometimes they enlarge to such an extent that they can be harmful to the brain. As soon as you witness the above-mentioned symptoms, book an appointment with a doctor.
With timely treatment and medication, doctors can reverse the growth of an acoustic vestibular schwannoma. 

What triggers this Disease?
The exact cause of this disease is not known. It could be any one of the following-
  A chromosomal anomaly or a malfunctioning gene
  Inhibition in the function of the protein suppressor that regulates the growth of Schwann cells

How is Acoustic Vestibular Schwannoma detected?
Your doctor will recommend these tests-

  Audiometry -
The audiologist will present sounds at different frequencies and you will have to make a gesture whenever you hear a sound. This will reveal the state of your hearing.

  Magnetic Resonance Imaging -
An MRI can detect the presence of a tumour that is 1-2 mms in diameter. If MRI causes pain or discomfort, a CT scan will be done.

Treatment -
If the tumour is tiny, your doctor won t prescribe medicines but your tumour will be monitored and imaged regularly so that the proper action can be taken as soon as it begins to enlarge.

  Surgery -
If the tumour is large, then you might have to undergo surgery. Not only will the tumour be removed, but also care will be taken to preserve the facial nerve so that facial paralysis does not set in.
You will be placed under general anaesthesia. The surgeon will drill a small hole in your skull near the ears and extract the tumour through your inner ears.

  Radiation -
If the tumour is small or if the patient is elderly and surgery can cause complications, doctors suggest radiation therapy. In this therapy, gamma rays are directed towards the tumour to shrink it.
Acoustic vestibular schwannoma can be treated if diagnosed on time. So, if you have noticed any symptoms, talk to a doctor right away.
