Sleep Apnea refers to sleep disorder which is characterized by irregular pauses or interruption in breathing during sleep. Every pause usually lasts for a few minutes or seconds and occurs several times at night. This may indicate that your brain as well as rest of your body is not getting sufficient supply of oxygen. Sleep apnea is of two types - Central Sleep Apnea (CSA) and Obstructive Sleep Apnea (OSA).

Obstructive Sleep Apnea- This occurs when the air passage gets blocked, generally when the throat muscles periodically relax and obstruct your air passage during sleep. It is the most common type of sleep apnea and is characterized by snoring.
Central Sleep Apnea- In this case, the airway does not get blocked, but the brain stops passing signals to the muscles that control your breathing.
Mostly people who are diagnosed with a number of underlying medical conditions such as obesity, diabetes, hypertension, chronic nasal congestion etc. are prone to Obstructive Sleep Apnea. Although Central Sleep Apnea is a less common type of sleep disorder, and does not lead to serious complications, various research studies show that Obstructive Sleep Apnea can pose adverse consequences if not treated at the right time.

One such fatal consequence is cardiovascular problems. Sudden drops in the levels of oxygen in blood that happens during Obstructive Sleep Apnea results can lead to increased blood pressure and damage of the cardiovascular system, which in turn increases the chance of a heart attack. Since men are more prone to heart ailments than women, men with sleep apnea are at a greater risk of heart ailments like stroke or heart failure, coronary artery disease and others.

Since Obstructive Sleep Apnea occurs due to interruption in the breathing procedure, it can lead to abnormal irregular heartbeats, known as arrhythmia. Arrhythmia can decrease the level of oxygen in blood and if there s an underlying heart condition, these repetitive encounters of low blood oxygen can even lead to a sudden cardiac arrest.

Most research studies have established a positive correlation between sleep apnea and heart ailment. According to researchers, the risk of untimely death increases as the acuteness of sleep apnea increases. However, there are ways of seeking treatment for this particular sleep disorder. You should consult a doctor immediately and get yourself proper medical assistance to prevent the condition from aggravating.

Can Sleep Apnea Be Fatal?

Epilepsy refers to a disorder in the central nervous system, where the brain starts to function abnormally, resulting in seizures or certain situations where the person starts to behave unusually, at the time even leading to loss of awareness.

A single instance of a seizure doesn t necessarily mean that a person has epilepsy. To be diagnosed with this type of neurological disorder, a minimum of two unprovoked seizures are usually required.

Symptoms

The main symptom of this kind of disease is repeated seizures but there are other instances as well when a person should consider seeing a doctor due to the fact that they might well lead to epileptic tendencies. Some of them are listed below:

The person becomes stiff all of a sudden
Little spells of a blackout or the memory are getting confused
If a person does not respond to questions or instructions for a brief period
A person seems to be in a daze and failing to communicate appropriately for a short span of time
If an individual is carrying out repetitive movements in an inappropriate manner
Causes

Epilepsy occurs when the brain is unable to send signals to other parts of the body, hence restricting our movements.

Though the exact cause is not known, still some generic factors inherited, can make epilepsy more likely happening and they are mentioned below as follows:

Head trauma suffered during a car crash
An injury which has might have occurred before birth
Due to faulty electrical activity in the brain, it is not able to send messages to other parts of the brain
Brain stroke or tumours can also increase the risk of epilepsy
People suffering from a developmental disorder like autism
Epilepsy can also be caused by infectious diseases like AIDS or Meningitis
Who Are Likely To Be More Susceptible To Epilepsy?

Children under the age of 2 years and adults aged more than 65 years are people most likely to get exposed to the risk factors, which might trigger the warning bells for epilepsy.

When Should You Go And Visit A Doctor?

You should visit a doctor or the emergency department of any hospital as and when you have the first seizure. Getting diagnosed with seizure disorder, change in seizure patterns or being affected by frequent seizures, also require immediate medical attention.

How Can Epilepsy Be Prevented?

Epilepsy can easily be prevented or at least the risk can be reduced if you follow certain measures:

Sleep for a minimum of 7 to 9 hours every day. Sleep deprivation is one of the major reasons behind increased number of seizures
Do not get stressed out and try to relax as much as possible
Drugs and alcohol should be avoided
As per doctor s advice, take all your medicines on a regular basis
Maintain a healthy diet
So, we have looked at certain aspects related to epilepsy, from which you could get a fair idea as to why and how this occurs and the ways in which you can prevent yourselves from getting affected

Epilepsy - All The Details Which You Need To Know

There is no trustworthy evidence regarding what causes brain tumors, but there are a few risk factors that have been substantiated through research. Children and young people who receive radiation around the head are susceptible to developing tumors in the brain once they grow up. Also, people with a certain kind of rare genetic condition like neurofibromatosis may develop a brain tumor though such cases are very few in number. Age is also an important factor as people aged over 65 years are diagnosed with brain tumors at quadruple times higher than children and younger people.

Types of Brain Tumours-

A primary brain tumor originates in the brain, and they may or may not be cancerous. Some tumors can be benign, which do not spread in the surrounding tissues and are not very malicious. However, that does not signify that they will not cause any harm over time. Sometimes these tumors can be severe and cause a threat to the life of the sufferer. The National Cancer Institute reports that approximately there were 23, 380 fresh cases of brain tumors in 2014.

Identifying the Symptoms of Brain Tumors...

The symptoms of the brain tumor are dependent on various factors such as the size, type as well as the exact location of the tumor. These symptoms are triggered when any tumor is pressed or clashed against a nerve or disturbs a part of the brain. Symptoms are also felt when any tumor particle blocks the fluid flowing around the brain or when there is a swelling in the brain owing to the build-up of fluid.

Common symptoms include- headaches that get worse in the morning, nausea along with vomiting, an alteration in the speech, hearing and imbalances in walking and movement, mood swings, change in personality and ability to concentrate or remember things and seizures or convulsions.

Treatment for Brain Tumor-

Surgery is normally the most usual treatment for brain tumors, and the patient is given anaesthesia, and the scalp is shaved before the surgery. Then, craniotomy is performed to open the skull, and the surgeon removes a bone piece out of the skull. Then the tumor is removed as much as possible. The bone is then restored back, and the incision on the scalp is closed. Sometimes surgery is not viable in case the tumor has developed in the brain stem or some other complex parts.

Neurosurgeons can surgically remove some tumors completely (called resection or complete removal). If the tumor is near sensitive areas of the brain, neurosurgeons will only be able to remove part of it (called partial removal). Even partial removals can relieve symptoms and facilitate or increase the effectiveness of other treatments.

The role of surgery in treating brain tumors

Surgery can provide:

- The complete removal of some brain tumors
- A sample to enable doctors to diagnosis the tumor and recommend the most appropriate treatment
- Better quality of life:
- Reduced symptoms and improved ability to function (e.g., to think, speak or see better)
- Less pressure within the skull from the tumor
- A longer life

In case you or any of your near ones is affected with brain tumor, you should visit the doctor to know the possible treatments other than surgery and other important questions related to brain tumor.

Brain Tumor - Causes, Symptoms and Treatment

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!

Brain tumours vary in shape and size and the same is the case with their symptoms. The location of the tumour affects the symptoms greatly. Just like in any other type of a malignant tumour, brain tumour has a rapid growth and proliferation of abnormal cells that may have its origin in affected site or areas adjacent to it. As per studies, every 2 in 1,00,000 people are said to be affected by brain tumour in India. However, it may come as a relief to some as not all brain tumors are cancerous or life threatening. Some are benign tumors and seldom pose any threat to the affected individual.

Types of Brain Tumor
Brain tumors may be primary or secondary.

Primary brain tumor: Here the abnormal mass of cells that originated in the brain do not metastasize to the other organs. Based on their location in the brain, the primary brain tumors may be of the following types.
Gliomas: One of the most common types of primary brain tumors, gliomas can have their origin in the spinal cord or the brain. Some of the common types of gliomas include Astrocytomas (originates in the cerebrum of the brain), Glioblastomas (these tumors form from the Astrocytes which form the supportive tissues of the brain), Ependymoma (these develop from the ependymal cells which are present within the CNS), Oligodendrogliomas (these tumors are found to arise from the oligodendrocytes).
Schwannomas: Also called as Acoustic neuromas, these primary brain tumors form on the nerves that play an important role in regulating the balance and hearing from the inner ear to the brain.
Meningiomas: These type of tumors are usually benign and have their origin in the meninges (membranes surrounding the spinal cord and the brain).
Primitive neuroectodermal tumors (PNETs): Primitive neuroectodermal tumors (PNETs) are rare malignant tumors that originate from the fetal (embryonic) cells in the brain.
Pituitary adenomas: As the name suggests, these tumors arise from the pituitary gland located at the base of the brain.
Medulloblastomas: Common among the children, these malignant primary tumors develop in the brain (lower back) and gradually spread via the spinal fluid.
Other types of primary brain tumors include Craniopharyngiomas and the Germ cell tumors.
Secondary brain tumors: Unlike the primary brain tumors, these tumors have their origin in the other body parts and organs (mostly in the lungs, skin, colon, breast, and kidney) and then gradually metastasize to the brain. The secondary brain tumors are found to be more common.
Symptoms or warning signs associated with brain tumors:
Some of the signs and symptoms that may be indicative of a brain tumor include

People with brain tumors often get seizures (due to the irritation caused by the tumors in the brain).
A headache (mild to severe depending on the part of the brain affected by the tumor).
A person experiences numbness or a tingling sensation in the legs and arms.
There may be difficulties in walking or balancing.
A person finds it difficult to concentrate.
There may be some problems with hearing, speech or even vision.
A person may experience weakness restricted to only one part of the body.
The symptoms may not necessarily indicate a brain tumor but it is always wise not to neglect the symptoms either.

Brain Tumor - What Are The Types?

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.
