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.

Acoustic Vestibular Schwannoma - All You Must Know About 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!

Polio is a virus that has the potential to infect any parts of the body including, but not limited to nerves and muscles. Primarily there are 3 types of polio namely, non-paralytic, spinal paralytic and bulbar. This disease shows minimal to no symptoms in more than 90 percent of the cases. 5 percent of the cases can show symptoms such as nausea, diarrhea, vomiting, sore throat and abdominal pain. Polio is a communicable disease and can cause massive damage if a proper dosage is not taken. It can spread through air, physical contact with an infected person, coughs etc.

Polio can cause paralysis: Polio has a far-reaching permanent effect on the body. It can cause paralysis on any of the limbs leading to permanent disability. This severely alters a child s life. The far-reaching consequences of the virus can only be negated through vaccination.
Weak muscle: Polio can result in weak muscles, respiratory problems and loss of reflex. If the breathing muscle collapses, it can result in the death of a person. Any of the above-mentioned symptoms can lead to weak body development altering the fate of a child.
It can spread fast and quick: Polio spreads very fast through the air, physical contact, saliva and water. It not only affects a single life but put millions at risk of the disease. A 1916 outbreak of the disease killed 6000 people in the United States and left several thousands of people disabled.
It reduces the risk of infection: 3 dosages Polio vaccination under the age of 6 can save a baby from getting polio in future. The body successfully creates polio antibodies from the vaccines and gets enough ammunition to fight it if the virus attacks it in future.
Social responsibility: Massive amount of awareness campaigns have been run by countries all over the world to permanently eradicate polio from the face of the earth. As per the latest reports, only 3 countries are reported to have babies affected with polio; Afghanistan, Pakistan and Congo. It is, therefore, a social responsibility to take part in the mission of removing polio from the face of the earth once and for all.
Save future generation: Although polio is not known to be a disease which passes through heredity, there still lies a chance for the future generation to get this disease. In order to negate that from happening, it makes sense to get the vaccines on time.
Give your kid a head start: Every kid deserves to have an equal amount of privileges like others. One small mistake on part of the parents can heavily cost a child s future. In order to make sure your kids grow up with any apprehension of polio, it is very important to treat them with polio vaccines.

Polio Vaccination - Why Is It so Important?

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.

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?

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.
