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?

A migraine is considered to be one of the worst headaches of all. It causes excruciating pain along with a range of other symptoms. Notably, a migraine pain is very different in nature compared to general headache. A migraine pain is mostly felt on any one side of the brain. Since a migraine is difficult to diagnose, here is a list of 5 signs that will help you to understand, if your headache qualifies as a migraine:

Vision splotches: It is very common among migraine patients to experience blind spots and a sudden flash of light. While this might appear to be a little unusual, it is pretty normal for migraine patients. The visual cortex of the brain is responsible for incidences like these. They often pace up and slow down to cause such unnatural feelings. For cases like this, the nerve gets activated by the optical lobe and crashes immediately resulting in such sensations. These visible auras are felt by both the eyes.
A spinning sensation: A migraine patient often gets a swirling sensation. This requires them to immediately lie down. This is accompanied with nausea and throwing up. Certain migraine-induced changes caused in the brain causes hearing imbalance which is very similar to vertigo. These auras often serve as the onset of a migraine and can last for over one hour before the actual migraine cycle starts. If a person is suffering from these symptoms, it is a clear indication that he is suffering from a migraine.
Light sensitivity: Migraine patients often becomes oversensitive to sound and light. This is perhaps the reason why most migraine sufferers like to spend more time in dark and solicitude. Studies have shown that sudden exposure to light activates the optic nerve fiber which in turn activates the pain receptors in the brain. A study conducted by the Nature Neuroscience journal conducted in the year 2010 showed that even blind person (with a migraine) suffers from a sudden glow of light.
Touch sensitivity: Sensory auras often cause sharp pain from tiniest of touches. This is a condition known as the allodynia. This is a condition by which the spine and the brain get super excited by the inflamed blood vessels. This condition should be reported to a doctor since the most common medicine of a migraine does not work well if a patient is suffering from allodynia.
Funny Face: Aura of the tongue, face and lips are known as cheiro-oral. There is a type of aura that makes even speaking and eating difficult. At time sufferers feel that they are suffering from serious diseases such as brain tumor. If this condition prevails, it makes sense to contact your doctor at the earliest and start medication.

5 Signs You Are Suffering From Migraine

What causes hearing loss? + How to ensure you can help it as you age

The partial or total inability to hear is known as hearing impairment or hearing loss. It can be present at birth, or develop later in life.

There are a number of factors, which may cause hearing loss

1. Age - Age is the biggest factor when it comes to the loss of hearing, and you may lose the ability to hear as you age. This condition is known as presbycusis. It becomes difficult to understand high-frequency sounds like that of a child or a woman when you get old.

2. Noise - When you are exposed to loud noises for a prolonged period of time, it damages your ears. This leads to loss of hearing. 5% of the total population of the world is affected by noise (the degree of suffering varies). It may be a result of continuous exposure to loud music or a sudden exposure to a loud noise like an explosion.

3. Hereditary disorders - Hearing disorder may be inherited by the dominant or recessive genes of parents in the child. 70-80% of these cases inherit from the recessive genes, whereas 20-25% inherit hearing loss from the dominant genes.

4. Trauma - Serious injuries of the head/ears may cause loss of hearing, which may be either temporary or permanent. When damage is caused to the brain, the brain fails to process the message conveyed by the ears. So even if the ears are totally functional, a person may face the problem in hearing.

5. Perinatal problems - The ototoxic effects on the fetus due to excess intake of alcohol during pregnancy lead to hearing the loss in about 64% of the infants born to alcoholic mothers.

Also, premature birth can be associated with hearing loss due to high risk of being exposed to noise in neonatal units.

Knowing about the causes of hearing loss can lead you a step closer to preventing this disorder as you age.

Here are some useful tips that can help prevent hearing loss:

1. Be more aware - You should be diligent and aware of the situations, which may risk your hearing ability and should try to avoid such situations as much as possible. Limit your exposure to sources of hazardous noises like firearms, firecrackers, concerts and clubs.

2. Take precautionary measures - If your occupation calls for working at an environment of loud noises, use earplugs or earmuffs to block out the excessive noise. Also, make sure that you work in a place where employers take all the necessary measures of noise control under the federal or state regulations.

3. Monitor your use of gadgets - Monitor and control the use of hearing devices, and try to reduce the use of headphones/ earphones as much as possible.

In recent times, the advancement of medical science has substantially contributed in comprehending the Alzheimer s disease. Unfortunately, the number of individuals suffering from the disease is expected to rise in the next ten years which pose a threat to the allocation of health care resources and public health. Alzheimer s disease is thought to be a complex disease which influences a person s behavior as well as cognition through numerous mechanisms.

Can surgery be deemed as a treatment for Alzheimer s disease?
The surgery is a multicenter clinical trial which is making a new direction in clinical research. It is devised to halt or slow down the problems caused by the disease which gradually erases a lifetime of memories in elderly patients. Though there is no cure for Alzheimer s disease, it has been found that low-voltage electric charges delivered right at the brain. Only the symptomatic therapies for Alzheimer s disease are provided which do not have any effect on the evolution of the disease. The standard medical treatments for Alzheimer s disease include cholinesterase inhibitors along with a partial N-methyl D-aspartate antagonist. In most cases of mild to moderate symptoms of this disease, a combination of treatments is used according to the clinical history, age and condition of the patient.

Mental activity supporting cognition
Many patients having normal cognition or mild impairment have a fear that they may develop AD. Many experts are of the opinion that mentally challenging activities including brain teasers and crossword puzzles can be helpful in reducing the risks in such patients. Clinical trials are under the way for determining whether or not these types of activities have any substantial effect on halting the progression of AD.

Treating AD in its moderate to the severe stage
Numerous studies have shown that blockade of NMDA receptors by memantine can be used safely in combination with ChEls. This combination has been shown to delay the institutionalization in patients with Alzheimer s disease.

Treating secondary symptoms
A variety of behavioral as well as pharmacologic interventions can help in overcoming the clinical manifestations of the disease. These include anxiety, psychotic behavior, depression and agitation among others. The effectiveness of this disease can range from modest to excellent. No particular agent or dose of it can be unanimously accepted to be the sole treatment option for the wide range of clinical issues. Moreover, in the recent time, the FDA has not accepted any psychotropic agent for treating AD.

Along with these treatment options, there are behavioral interventions that can range from patient-centred approaches to caregiver training for helping manage the cognitive and behavioral manifestations of Alzheimer s disease. Last but not the least, it is very crucial to point out the significance of treatment in the early stages of AD in order to cure it better.

Alzheimer's Disease - Can Surgery Help You Treat 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?

One of the common ailments in the elderly people is the Parkinson s. A progressive disorder, when left untreated, results in worsening of the symptoms. Hence, it is essential to understand the treatment options available to manage the condition effectively. You may be suggested surgical therapies if medication is not effective enough to treat the symptoms.

Surgical treatment options can be beneficial for patients who are suffering from symptoms, but they do not help with treating the disease. In the past, surgical methods like Thalamotomy and Pallidotomy were used to destroy brain cells that contributed to the symptoms. While these methods are still used, they are very rare and situational.

Deep Brain Stimulation (DBS), an FDA-approved procedure, has become much more popular as it is much safer and does not involve invasive surgery. Instead of destroying brain cells like traditional methods, DBS involves sending electric pulses to the affected brain cells to reduce the symptoms. It is not a treatment procedure, but a means of bringing down the severity of Parkinson s to allow better and more comfortable treatment.

Deep Brain Simulation   Who are the right candidates?
Deep Brain Simulation is commonly used for Parkinson  s disease, but it is not recommended for everyone. It is a preferred method of treatment for people who have had Parkinson s for at least four years but have complications which include long periods of time where medications do not work, or symptoms return, uncontrolled and involuntary movements or the freezing/stiffness in the body.

Deep Brain Simulation is not recommended for those who have Dementia as it can lead to memory problems. The general rule of thumb that neurosurgeons follow is that Deep Brain Simulation can help with symptoms that do not get better with medication. DBS can help reduce medication requirements for patients as well as reduce the side effects that may occur due to medication.

Disorder specialists and neurosurgeons can conduct tests to determine if DBS is going to be effective for a patient before going ahead with such a procedure. An extensive assessment is necessary to understand the symptoms, the effect of Parkinson's drugs and also brain imaging is done. All of the expected benefits are then evaluated for the patients, and if the procedure can help alleviate the symptoms, DBS is given a green signal by neurosurgeons and patients can undergo the procedure.

How Does Deep Brain Simulation Work?
Deep Brain Simulation is a very complex procedure. Brain cells communicate with the rest of the body through electric signal, and these become irregular and do not work properly when affected by Parkinson's. DBS smoothens the functioning of these brain cells and reduces symptoms through electric pulses through the implantation of a medical device known as neurostimulator which is also referred as brain pacemaker.

But, as with any treatment procedure, DBS has potential risks and side effects, hence discuss with neurosurgeon thoroughly to access the suitability.
