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?

Parkinson s disease usually develops at a very slow rate and the early signs of this disease often go unnoticed. As the condition progresses, the symptoms become more prominent. Parkinson s disease affects the nervous system and cannot be completely cured. However, with proper treatment, its rate of progression can be slowed and this condition can be managed. The earlier a diagnosis is made, the more effective treatment will be. Thus, it is important to be able to recognize the signs the symptoms of this disease.

The signs and symptoms of Parkinson s disease vary from person to person. In most cases, symptoms begin on one side of the body and are worse on that side even after it begins to be noticed on the other side. These symptoms can include:

Tremors
Involuntary shaking of a part of the body is usually the first sign of Parkinson s the hands are most affected by this symptom. These tremors can be felt while performing an activity or even when the hand is at rest. In some cases, it can even keep a person from performing normal tasks such as writing. Tremors caused by Parkinson s can also take the form of an uncontrollable back and forth rubbing movement between the thumb and forefinger.

Slow Movements
This is also known as bradykinesia. As the disease progresses, it can slow down movement and reduce the person s ability to move. Simple tasks such as walking can become more difficult and take much longer. The person s steps may become shorter and they may also drag their feet as they walk. Parkinson s patients may also find it difficult to get in and out of chairs.

Rigidity
Parkinson s can make muscles stiff and difficult to move. This can affect the muscles of any part of the body. This rigidity can limit the person s range of movement and make moving the affected muscles very painful.

Loss of certain movements
In addition to muscle rigidity, the person may not be able to make certain movements that we take for granted. For example, he or she may not be able to blink or smile. Swinging the arms while walking may also become more difficult.

Changes to speech
Parkinson s can make a person speak slower and reduce his or her natural volume. The person s speech may also sound slurred. In addition, they may find it difficult to speak with inflections due to which their speech may appear to be monotonic.

Imbalance
Parkinson s may affect a person s posture and balance. In many cases, Parkinson s patients develop a stoop. The loss of balance can make climbing stairs difficult and cause them to fall easily.

Parkinson's Disease - Signs And Symptoms You Should Know About It!

Antibiotics are something which have changed are lives for eternity as well as for the better, to say the very least. With each day that passes, there are greater strides of advancement which are made in the field. Of late, it is said that antibiotics also have the potential to stop new cells in the brain from growing, which is quite a risk when it comes to their usage among people are sick.

Research has found that if the brain of the person under treatment is subject to sustained use of antibiotics, it is true that the brain can lose its functionality for a quicker time than what one would consider to be normal. So it can be said, this usually is not the advisable way to go.

Like most testing practices when it comes to medication, antibiotics which were tested on the brains of the subjects i.e. those of mice had an effect of mitigating their high-level memory. How this happened to be is rather interesting, to say the very least.

How dangerous can antibiotics be?
It is often said that eating right does wonder for a person s brain. Well, the mice that were not treated with the antibiotics were seen to lose the healthy bacteria present in their stomachs. In addition to this, they lost new brain cells. This led on to them performing worse in mental tests than their peers who had had some antibiotics administered to them on a consistent basis.

Now a cynic may point out that what is seen to be true for mice may really not hold true when it comes to humans being considered. However, if it is taken into due account that a lot of path-breaking research is carried out on mice, there is quite some credence to the results of the study.

To supplement the evidence even further, it was also seen that for mice which were in possession of low levels of monocytes, which are a type of white blood cells. It was seen that there was a great dependency on monocytes for the generation of white blood cells. The part of the brain which is hindered by generating new cells on account of the sustained use of antibiotics is the hippocampus.

Antibiotics are the proverbial shot in the arm which can aid recovery by destroying the threat to a person s wellness. However, it is to be considered that they are not safe in general as there is collateral damage!

Antibiotics - Can They Stop The Growth Of Brain Cells?

Neurology is the branch of science and medicine dealing with the central and peripheral nervous system. The nervous system is made of the brain and spinal cord. The disorders, illness or injuries of the nervous system can become problematic for people suffering from them. One of the worst diseases of the nervous system is Parkinson s disease.

It is a progressive disorder affecting the central nervous system that leads to slowing down of movement and slurring of speech over a period of time. It is a condition where the nerve cells in the brain producing dopamine (a neurotransmitter) are affected.

Some of the early signs of Parkinson s include:

Tremor: If you have noticed a slight shaking of your hands or limbs, then Parkinson s might be the cause. The trembling can range from mild to severe as the disease progresses. The back-and-forth rubbing of your thumb and forefinger is known as pill-rolling tremor. One of the most prominent signs is your hand shaking even when it is rested.
Bradykinesia (slow movement): As the disease progresses, you may find it difficult to move your hands or legs or going from one place to another. Even making the smallest movement will require an increased effort on your part.
Rigid Muscles: The muscles in your body can become stiff causing you pain and making it difficult to perform physical activities.
Masked Face: Your face may experience spasms or become stiff periodically. It can also lead to complete paralysis on one side of the face.
Stooping or improper balance: Having Parkinson s disease can make your body posture imbalanced resulting in stooping or hunching over.
Decreased Automatic Movements: You may experience difficulty in smiling, blinking or swinging your arms while walking.
Alteration in voice or speaking: Your voice can become soft or you may slur while talking. You can also experience a monotonous voice.
Writing may become small: You can experience changes in your handwriting as it becomes small and crowded.
Loss of Smell: The smell of food sitting right in front of you may not register in your olfactory resulting in loss of appetite.
Constipation: Having Parkinson s disease can lead to patients experiencing irritable bowel syndrome.
Have Trouble Sleeping: It might be difficult to fall asleep for people suffering from Parkinson s. Also, there are sudden movements during the sleeping process.
Dizziness: People suffering from Parkinson s may faint from time to time.
These were some of the symptoms and signs by which you can tell whether a person has Parkinson s or not. However, as of now it is not curable and can only be treated with medicines. But, early detection can definitely help in preventing it from affecting the whole body.

Parkinson's Disease - Are You Aware Of These Signs?

Women are not really sure about frozen embryos  ability to result in pregnancy. Ironically, the success of Frozen Embryo Transfer has dramatically improved over the last few years. In the days gone by, the chance of women getting pregnant through the use of frozen embryos seemed to be on the lower side compared to that from the transfer of fresh embryos. Recent data related to this suggests that this is no longer the case.

Reasons behind the low success rate of frozen embryo transfer in the past
Previously during the frozen embryo transfer process, the embryos which had to get frozen were the ones that did not get chosen for the fresh embryo transfer initially. The reason being that the embryologist had gone ahead to choose the best possible embryos for getting them transferred initially. As far as the fresh embryo transfer is concerned, quality of embryo has got a major effect on the chance of a woman getting pregnant. On the other hand, if quality of embryos frozen is not good, the rate of survival after it gets thawed along with the rate of pregnancy would be on the lower side.

The second important reason is the amount of embryos that got transferred. Let us consider a couple who produce four very good quality embryos. Two of them are transferred during fresh In Vitro Fertilization Process and the remaining two are frozen. This leads to pregnancy and the woman gives birth to a baby. Later on, the couple once again decides to go for pregnancy by using the frozen embryos. Though only one embryo survives after getting thawed. The frozen embryo transfer is that of a single embryo. The success rate of a frozen embryo transfer through a single embryo is always going to be on the lower side than what it will be when multiple embryo transfer is involved.

Finally the method of freezing embryos has seen a sea change quite a number of years ago. Nowadays the freezing of embryos takes place by a fast method, known as vitrification. This process has got a much better survival rate when embryos get thawed along with good rates of pregnancy when those particular embryos are transferred in a much better manner.

Studies about high success rate of frozen embryo transfer
There have been studies performed in women, who have had quite a vigorous stimulation of their ovaries and were considered to be at high risk for Ovarian Hyperstimulation Syndrome. The physicians took the decision of skipping the process of embryo transfer and instead go ahead to freeze all the embryos for use at a later stage.

This tends to significantly decrease the risk of having serious Ovarian Hyperstimulation Syndrome along with decrease in complications. Other cases involved, physicians deciding to move on with a fresh embryo transfer depite the risk of Ovarian Hyperstimulation Syndrome. In both the scenarios the couples have quite a large number of embryos and the embryos selected for transfer were the best embryos.

The studies have shown no difference in the rates of pregnancy between fresh or frozen embryos or for that matter higher rate of pregnancy with frozen embryos.

How Successful Is Frozen Embryo Transfer?

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.
