Epilepsy is a disorder in the central nervous system characterized by recurrent seizures. An unexpected rush of electrical activity inside the brain leads to a seizure. Brain activity becomes abnormal and leads to periods of unusual behaviour with loss of awareness at times.

Seizures do not always include unusual muscle movements or convulsions. Untreated seizures can seriously affect the lives of children having them. Epilepsy affects both men and women regardless of their ethnic background and age.

Signs of Epilepsy:

A staring spell
Momentary bewilderment
Loss of consciousness
Jerking movements of arms and legs.
Panic or anxiety
Kinds of Seizures:
Seizures are normally classified as focal or generalized depending on the commencement of abnormal brain activity.

Focal (partial) seizures result from abnormal activity in a particular area of the person's brain. Simple partial seizures may change emotions or the way things smell, appear, feel, sound or taste. It is characterized by tingling and dizziness.
Complex partial seizures or focal seizures with impaired awareness entail a modification of or loss of awareness and consciousness. Repetitive movements are performed during such seizures such as hand rubbing, walking in circles or swallowing.
Thorough testing is needed to differentiate epilepsy from other neurological disorders such as narcolepsy, migraine or mental illness.

Generalized seizures normally affect all areas of the brain and consist of:

Tonic seizures lead to muscle stiffness and normally affects muscles in the person's back, legs and arms.
Atonic seizures or drop seizures lead to a loss of muscle control which makes a person abruptly collapse or fall down.
Myoclonic seizures are visible as short jerks or twitches of a person's arms and legs.
Clonic seizures are characterized by repetitive or rhythmic jerking muscle movements.
Tonic-clonic seizures cause sudden loss of consciousness, quivering and body stiffening.
Absence seizures might take place in clusters and lead to momentary loss of awareness.
Symptoms of Epilepsy:
The main symptoms of epilepsy are seizures and it differs from one person to another.

Symptoms of Focal (partial) seizures include:

Dizziness
Change or modification in the sense of smell, taste, hearing, sight or touch.
Twitching and tingling of limbs.
Symptoms of Complex partial seizures include:

Unresponsiveness
Staring blankly
Performing repetitive movements
Loss of awareness or consciousness
Genetics may provide a person with a natural seizure threshold as a person who is susceptible to seizure triggers is said to have inherited a low seizure threshold. A higher threshold conversely makes a person less liable to have seizures.

Epilepsy is a comparatively common neurological disorder that affects innumerable people worldwide and treatments range from medication to surgery.

Epilepsy - Signs and Symptoms You Must Know!

Cochlear Implant is an electronic device replaced with the inner ear (cochlea) of the patients who are unable to send sound waves to the brain.

The surgery is performed on the patients who have the problem of hearing loss due to the damaged hair cells in the inner ears. The implant helps the patient to hear which are not responding to other hearing aids.

Conditions for Cochlear Implant:

Cochlear implants help people to hear with clarity. They are not like hearing aids, which make the sound louder, but it helps send sound waves to the brain and replaces the damaged hair cells in the inner ear. Following are cases where it is beneficial:

People who find it difficult to hear clearly with hearing aids.

Those with moderate hearing loss in both ears.

Patients with 50% or fewer score in the sentence recognition test.

Patients with 60% or less score in sentence recognition test with hearing aids on.

It is suggested to opt for cochlear implants in both ears. The reason is to give the patient a better perspective of sound direction and clarity in understanding the words.

How does the Cochlear Implant work?

Cochlear Implant is an electronic device with an embedded sound processor that has to be worn outside ears or on the body. Following steps are involved in cochlear implant:

The sound captured by the processor is converted digitally by the processor and sent to the coil inside the ears of the patient.

The implant converts digitally coded sound waves to electrical impulses.

The electric impulse simulates the hearing nerve of the patient.

Then sends these impulses to the brain.

Benefits of Cochlear Implants:

The cochlear implant is a blessing for people who have been suffering from hearing loss for a very long time. It provides aid to people who have not benefited from hearing devices. The benefits of the cochlear implant are:

Hear better.

Studies have shown that people with cochlear implants have better sentence recognition scores instead of hearing aids.

The patient can concentrate better in the crowd and can hear conversations across the table.

Reconnect with the missed sounds.

Enjoy music on the phone.

Cochlear Implant improves the quality of life of people with hearing loss. It gives them an aid to understand and engage themselves in a conversation. However, it takes time to learn the interpretation of the sound signals that are received from cochlear implants. But, the patient can learn and lead a normal life with the implant. The factors which affect the benefits of Cochlear implants are:

The extent of hearing loss

The duration of the hearing loss and the condition before implantation

Damage to inner hair cells

Other health issues

The practice and rehabilitation time have been done in practice after implantation

The cochlear implant is performed in the patients after taking extensive tests determining the condition of the patients. It is activated after 2-6 weeks of surgery to give the surgery site a time to heal. Most people are discharged from the hospital after surgery and are prepared for the use of an implant. There are training sessions and classes for patients who have just gone for cochlear implants.

Cochlear Implant - How Do They Help?

The brain contains numerous nerve cells which help in its normal functioning. Epilepsy or seizures occur when there is a disruption in the activity of the nerve cells in the brain. A neurological disorder of the CNS (Central Nervous System), epilepsy can affect all and sundry, irrespective of their age, sex and ethnicity. However, children and aged people (above 60 years) are more susceptible to the condition. A study suggests approximately 10 million people in India suffer from epilepsy.

Types of Epilepsy
Based on the activity of the brain that causes an epileptic attack, Epilepsy can be of two types - Focal or Generalized
Focal Epilepsy: An epileptic attack triggered by unusual activities restricted to a particular area of the brain.

In some cases, focal epilepsy may result in unconsciousness. A person may also lose awareness and become unresponsive (keeps staring into space), a condition termed as Focal Dyscognitive Seizures. A person with this condition may behave strange, such as walking in circles, chewing or rubbing their hands.
In another type of focal epilepsy known as Focal seizures without loss of consciousness, a person does not lose consciousness. In such cases, there may be sudden and involuntary jerking of the arms or the legs. There may also be dizziness or a tingling sensation.
Generalized Epilepsy: Here, the seizures or epilepsy result from unusual activities throughout the brain. Generalized epilepsy, may, in turn, be of the following subtypes

Tonic seizures: This affects the muscles of the legs, arms, or the back, causing them to stiffen and tighten up.
Atonic seizures: Here, a person may suddenly fall down due to loss of muscle control. The condition is also known as Drop Seizures.
Absence seizures: Mostly affecting children, the affected person may lose awareness (temporary) and behave strangely such as staring into spacing, smacking their lips, or blinking their eyes continuously.
Clonic seizures: They are characterized by sudden and continuous jerking movements of the arms, face, and neck muscles.
Tonic-clonic seizures: Here, a person may suddenly lose consciousness. There are violent shaking and stiffening of the body. Some people may even be seen biting their tongue.
Myoclonic seizures: In this arms, and legs of a person suddenly twitches and jerks.

What triggers an Epilepsy?
Epilepsy may be an outcome of the following factors

Medical conditions such as stroke or even brain tumors may affect the normal activities of the brain, thereby resulting in epilepsy. Diseases such as Viral Encephalitis, AIDS or Meningitis act also act as a trigger, accelerating the chances of epilepsy.
Developmental disorders such as Neurofibromatosis or Autism can also trigger epilepsy.
In some cases, epilepsy may be a genetic predisposition. Thus, a person with a family history of epilepsy may suffer from the condition.
Epilepsy may also be an outcome of a prenatal brain injury due to oxygen deficiency or an infection to the mother.
People with dementia may also suffer from an epileptic attack.

Epilepsy - Know The Most Common Types!

Headaches and migraines can vary drastically depending on their duration, specific symptoms and the person they are affecting. The more you know about your specific type of headache or migraine, the better prepared you will be to treat them and possibly even prevent them. The two types of migraine are- 

Migraine without aura: The majority of migraine sufferers have Migraine without Aura. 
Migraine with aura: Migraine with Aura refers to a range of neurological disturbances that occur before the headache begins, usually lasting about 20-60 minutes.
Symptoms of migraine vary and also depend on the type of migraine. A migraine has four stages: prodrome, aura, headache and postdrome. But it is not necessary that all the migraine sufferers experience all the four stages.

Prodrome: The signs of this begin to appear a day or two days before the headache starts. The signs include depression, constipation, food cravings, irritability, uncontrollable yawning, neck stiffness and hyperactivity.
Migraine Aura: Auras are a range of symptoms of the central nervous system. These might occur much before or during the migraine, but most people get a migraine without an aura. Auras usually begin gradually and increase in intensity. They last for an hour or even longer and are 

Visual: Seeing bright spots, various shapes, experiencing vision loss, and flashes of light
Sensory: Present in the form of touch sensations like feeling of pins and needles in the arms and legs
Motor: Usually related with the movement problems like the limb weakness
Verbal: It is related with the speech problems
Headache: In case of a migraine attack one might experience:

Pain on both sides or one side of the head
Pain is throbbing in nature
Vomiting and nausea
Sensitivity to smells, sound and light
Vision is blurred
Fainting and lightheadedness
Postdrome: This is the final phase of the migraine. During this phase one might feel fatigued, though some people feel euphoric.

Red flags that the patient may be having underlying serious disorder not migraine

Onset of headaches >50 years 
Thunderclap headache - subarachnoid haemorrhage 
Neurological symptoms or signs 
Meningism 
Immunosuppression or malignancy 
Red eye and haloes around lights - acute angle closure glaucoma 
Worsening symptoms 
Symptoms of temporal arteritis
These patients require CT scan / MRI or CSF examination. Most Migraine patients do not need these tests. 

Diagnosis of Migraine: Usually migraines go undiagnosed and thus are untreated. In case you experience the symptoms regularly then talk to the doctor, who evaluates the symptoms and can start a treatment. You can also be referred to a neurologist who is trained to treat the migraines and other conditions. During the appointment the neurologist usually asks about the family history of headaches and migraines along with your symptoms and medical history.

The doctor might advise for some tests like:

Blood Tests: These reveal problems with the blood vessel like an infection in the spinal cord and brain.
CT scan: Used to diagnose the infections, tumors, brain damage, and bleeding that cause the migraines.
MRI: This helps to diagnose the tumors bleeding infections, neurological conditions, and strokes.
Lumbar Puncture: For analyzing infections and neurological damages. In lumbar puncture a thin needle is inserted between the two vertebrae to remove a sample of the cerebrospinal fluid for analysis.
Treatments

Migraine treatments can help stop symptoms and prevent future attacks.

Many medications have been designed to treat migraines. Some drugs often used to treat other conditions also may help relieve or prevent migraines. Medications used to combat migraines fall into two broad categories:

Pain-relieving medications. Also known as acute or abortive treatment, these types of drugs are taken during migraine attacks and are designed to stop symptoms.
Preventive medications. These types of drugs are taken regularly, often on a daily basis, to reduce the severity or frequency of migraines.
Your treatment strategy depends on the frequency and severity of your headaches, the degree of disability your headaches cause, and your other medical conditions.

Some medications aren't recommended if you're pregnant or breast-feeding. Some medications aren't given to children. Your doctor can help find the right medication for you.

Migraine - Identifying the Early Signs!

Brain tumor refers to the development of unusual cells in the brain or around the nearby tissues and structures. Pediatric Brain Tumor means the development of these unusual cells in the brain of children. There are two types of brain tumors: Benign or non-cancerous and malignant or Cancerous. Tumors like ependymoma and medulloblastoma are quite common among children. The treatment of the tumor is determined by its severity, type, location, age, and overall health of the child. The treatment of Brain Tumor in children is different from the adult s treatment. One should ensure to consult with the pediatrician with the specialty in cancer and neurology. Brain Tumors in children are Primary Brain Tumors that develop in the brain or nearby tissues. This Primary Brain Tumor develops when the usual cells have DNA mutations or alterations. The alterations in the DNA permit the cells to develop and distribute or split with an increased rate and destroy the healthy cells. This leads to the development and collection of unusual cells forming a tumor. In most Primary Brain Tumor cases, the cause is not clear. Children with a family history of the genetic syndrome and Brain Tumor are more prone to the problem.

Symptoms-

The symptoms of the Pediatric Brain Tumor depend upon the severity, location, and type. There are a number of symptoms that are really common and are shared by other diseases. Other than this, there are symptoms which are possibly the signs of Brain Tumor among children. Adults and parents should consult a doctor if they find their children having the symptoms and signs for an unusual time.

Hearing issues

Frequent and severe headache

Fuller fontanel (soft spot) on the baby s skull

Vomiting or nausea

Behavior changes

Seizures

Sudden vision problems like double vision

Abnormal or strange eye movement

Increased heaviness or pressure in the head

Irritability

Slurred speech

Difficulty in swallowing

Weakness

Loss of appetite

Drooping on one side of the face

Difficulty feeding in babies

Loss of sensation on one side of the body

Imbalance or difficulty in balancing

Difficulty in walking

Diagnosis-

The diagnosis for the Pediatric Brain Tumor includes many lab tests. The doctor may initiate with some neurological examination like hearing, vision, reflexes, balance, and coordination. Any abnormality in these tests will lead to further examinations. There are some imaging tests that are used to determine the size and location of the tumor in the brain. These tests include MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography), and CT (Computerized Tomography). After the confirmation of the presence of a Brain Tumor, the specialist will further move to the Biopsy. It includes the removal of a sample tissue for analysis or testing. The type of biopsy that will be performed on the patient depends upon the location of the tumor. Other than the biopsy, the tumor tissue can be examined for molecular basis and genetic mutations. After that, Drug therapy can be designed according to the individual s requirements. It is important for the doctor and the patient to know if the tumor has been spread through cancer in other parts of the body. If it is true, then the doctor will perform more tests and examinations to know the root and initial location of cancer for further treatment.

Treatment-

The treatment of the Pediatric Brain Tumor is determined by the severity, location, size of the tumor, and age and health of the child. There is a number of treatments available with modern technology but their usage depends upon the patient s requirement.

Surgery that is used when the location of the tumor is approachable via surgery. When the brain tumor is small, it can be completely removed by the surgery. But when the tumor tissues are located nearby sensitive areas of the brain, then the surgery becomes risky and maximum tumor tissues are tried to be removed through surgery. The risk of the surgery depends upon the location of the tumor. An example can be vision loss if it is anywhere near the nerves connected to the eyes.

Targeted Drug Therapy helps to destroy the abnormalities of the cancer cells resulting in the destruction of the cancer cells.

Radiation therapy is used to kill the tumor cells by using high-energy beams. Radiation therapy can either be given by an external machine (external beam radiation) or in exceptional cases, radiation is positioned within the body (brachytherapy) near the tumor.

Chemotherapy includes the consumption of drugs to destroy the tumor cells. These drugs can be consumed in tablet form but for children, the drugs are mostly injected (intravenous chemotherapy).

Stereotactic Radio Surgery includes various radiation beams to perform extremely focused radiation therapy to destroy the tumor cells located in a small part.

Proton Beam Therapy carries higher targeted radiation doses to the tumor cells with minimum exposure of radiation to the healthy cells and tissues. It decreases the chance of development of fresh cancer cells.

Take Away-

Pediatric Brain Tumor is the development of unusual cells in the brain or around it. Although this is a life-threatening problem, however, with advanced technology, it can be treated successfully. There are no specific causes discovered by specialists but genetic mutations and family history cause it. The symptoms can be really common like headache and nausea but can also be specific like difficulty in coordination, reflexes, speech, and many more. The timely diagnosis and treatment can give a new life to the child and reduces the chance of development of fresh tumor cells in the future.

Pediatric Brain Tumor - Know In Detail About It!

Sleep apnoea is a kind of disease that can affect people of any age and is basically a kind of sleep disorder. The person suffering from sleep apnoea may feel extremely tired and fatigued even after having a full night s sleep and his snoring may become extremely loud which is again a serious problem.

What are the symptoms of sleep apnoea?

There can be many cases where the symptoms of central sleep apnoea and complex sleep apnoea may be overlapping which makes it a bit difficult to get diagnosed properly. But, there are certain very basic symptoms of sleep apnoea.
Very loud snoring is a basic characteristic of patients with sleep apnoea.
The patient may suffer from regular episodes of cessation when they are sleeping as might be pointed out by other people.
The patient may awaken from sleep regularly due to shortness of breath and problems in the sleeping order.
The patient suffering from sleep apnoea may wake up from sleep with a very dry mouth and or a sore throat.
The patient may suffer from a bad headache often and in many unfortunate cases, the patients may also suffer from insomnia which is the problem of sleeplessness.
Patients of sleep apnoea suffer from intense problems of irritability and bouts of morning sleepiness.
Shortness of breath may intensify in a patient so much so that the person may get awakened from sleep gasping for air as if choking.
Excessive bouts of daytime sleeping may cause a person to perform very poorly in his work as well.
It is at these times when a patient should immediately consult a doctor for a proper treatment and further solution to this problem.

Causes of sleep apnea

Obstructive sleep apnoea is caused when the muscle in our throat starts relaxing. It is this muscle that gives support to the triangular piece of tissue that hangs from the uvula which is the soft palate and the side walls of the tongue. Basically, when this muscle relaxes, the airways in the body gets narrowed as a result of which the blood does not get enough oxygen which is required for proper breathing. It is then that the brain starts sending signals to get up from sleep so that the nasal passage can be reopened for sufficient amount of oxygen.
There can also be cases where the brain is unable to send a proper signal to the muscles that help us to breath as a result of which a person does not breathe for a certain period of time. This, in turn, makes the patient awaken abruptly from sleep with shortness of breath and the patient finds it difficult to fall asleep.
