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!

Living with epilepsy can be highly challenging. This is a medical condition that can be controlled with medications in most cases, but it might not be useful for all patients due to severe side effects. It is estimated that up to 30% people who have epilepsy face this issue, and in such cases, surgery might be considered as an option.

This condition typically results in seizures which is a result of sudden electrical activity in the brain. So, certain complicated epilepsy operations on the brain can help patients with their seizures and contain their symptoms.

The goal of epilepsy surgeries involves removing part of the brain that causes these seizures and disrupting parts of the nervous system in the brain that contribute to the same. The procedure also involves the installation of a device that helps control the side effects of epilepsy.

When is surgery not an option for epilepsy?
Doctors would accurately identify the part of the brain that is causing seizures as the first step. These parts are known in medical terms as the  seizure  focus. This area should not be related critical functions of the brain like movement, sensation, and language involved   else surgery would not be possible.

Surgery is not viable when seizures are severe and impair bodily movement or if the patient has serious medical conditions (like cancer or heart diseases).

Common Surgery Options Available

Lesionectomy: This is one of the most commonly used procedures. This form of surgery involves the surgeon removing brain lesions from the brain or areas of injury due to malformed blood vessels or tumors. These injuries can often cause seizures and epilepsy and can be treated effectively with lesionectomy.
Lobe resection: This is another form of treatment which is possible only if the epilepsy is located in one of the four parts of the brain   the temporal lobe. It is quite common in younger people and can easily be treated by expert neurosurgeons by removing the brain tissues that are causing epilepsy.
Multiple Subpial Transections: While the above methods involve cutting out brain tissues, sometimes such surgeries just might not be possible due to other complications. If the parts of the brain cannot be cut out, surgeons tend to adopt Multiple Subpial Transections. This procedure can help control seizures without requiring cutting out parts of the brain. Small intersections are made in the brain to disrupt the impulses from affected brain cells that cause seizures, and they do not affect normal brain activity. It helps leave all abilities intact in patients and aids in treatment very effectively.
So, if you are just fed up with dealing with the seizures, consult your doctor who will be able to advise on the course of action depending on the history and medical condition.

Epilepsy - Is Surgery An Option?

Leading a life with peripheral neuropathy is quite similar to riding a roller coaster. Managing the pain can be frustrating at one time and overwhelming on the other as patients can experience alternating symptoms with debilitating pain. So you should learn about the various treatment options as they can help you go a long way in managing the pain.

The peripheral nerves are considered the longest in the body which extend from the hands to feet. When these nerves are damaged, you may feel some sort of pain, tingling in the hands and feet and even numbness, and these symptoms can even get worse and you may experience stabbing pain with increasing weakness. 

There are many things that you should know about peripheral neuropathy as they would help you to manage the condition much more effectively.

Diabetes is the leading cause of neuropathy: More than 70% of diabetics develop symptoms of peripheral neuropathy. So you should keep your blood sugar within optimum levels as a means of reversing diabetic neuropathy.
A melange of causes behind neuropathy: Though diabetes is the number 1 cause of peripheral neuropathy, other causes include deficiency of vitamin B12, alcoholism, traumatic injury, chemotherapy and exposure to toxic substances. Physicians may find it difficult to pin-point the cause and when this happens. This is often termed as  idiopathic neuropathy .
Medications causing neuropathy: If you are suffering from diabetes and being treated with the drug named metformin, you may develop peripheral neuropathy.
Preventing neuropathy is the most recommended way: While it is the fact that some nerves may potentially get damaged from certain surgeries or injury, peripheral neuropathy can be potentially prevented or sometimes stopped from spreading. As diabetes is a major cause of diabetes, being watchful about your diet and exercising regularly can help you go a long way to prevent diabetes as well as neuropathy.
Pain is not simply confined to a tingling sensation: Though pain and a tingling sensation is the commonest and easiest way of recognising the symptoms of peripheral neuropathy, each of your sensory, motor and autonomic nerves can show different set of symptoms that you should be watchful of.
A diet may make the symptoms even worse: You can either help or hurt your nerves with your choice of foods. For improving symptoms, you should avoid food with excessive sugar, refined grains and artificial sweeteners as they may strain your nerves and irritate them further.
Whether you are recently diagnosed with peripheral neuropathy or living with it for many years, understanding a few conditions would help you make informed decisions about your well-being.

Peripheral Neuropathy - 6 Things You Should Know!

Hearing loss is not something limited to elderly men or elderly women only. This is something that can affect any adult at any stage of life. The good news is that it can be managed. Today, there are a number of hearing aids that can help improve hearing ability. These aids allow an individual who has lost part of his or her hearing to live a normal life. For best results, hearing loss should be arrested in its early stages.

Here are a few signs you should look out for.

Muffled Speech: When you hear people talk, their speech should be clearly identifiable. If you hear muffled noises that you have to interpret as words, it could be a sign of hearing loss.
Difficulty understanding words: The human ear has the ability to separate conversational sounds from ambient noise. However, in some cases where the inner ear is damaged, a person might find it difficult to separate the two. In such cases, the person might not be able to understand words clearly as they get confused with background noise. This is a sign that must never be taken lightly.
Feeling the need to ask people to repeat themselves: Once in a while if you find yourself asking another person to repeat what he or she said, there is nothing to worry. However, if this becomes a regular occurrence and happens with many people, then the fault lies in your hearing. Thus, if you notice yourself needing to ask people to repeat themselves or talk slowly, consult a hearing specialist.
Increasing the volume of the radio or television: As children, we are taught that playing music or watching TV at a very high volume can damage the ears. The radio, television and other such appliances should be played at a volume where the information being relayed is clearly audible and people can have a conversation alongside without needing to shout. If you find yourself having to increase the volume constantly, it could be a sign of hearing loss.
Withdrawing from conversations: As hearing loss is aggravated, people begin to feel conscious of having to ask others around them to repeat themselves or talk slowly. This can make them withdraw from a conversation and other social situations. In many cases, the simple reason for avoiding a party could be the discomfort of not being able to hear the other person clearly in a conversation.
 All hearing problems can be better handled by proper investigation, different test, sign and symptoms of the patient, which are carried by a specialist of hearing, called as AUDIOLOGIST, who can look your hearing problems, plan out treatment plan, rehabilitation pre and post etc. Audiologist will definitely help you hear again. 

Common Signs Of Hearing Problems In Adults!

Autism spectrum disorders are a group of severe neurological and developmental disorders which begin in early childhood and can last throughout a person s life. It affects the ability to interact with others and also hinders communication and well as learning ability. A proper health center can diagnose the presence of autism spectrum disorder early on. Many tests are available for evaluation and diagnosis as it is a range of disorders which can have a variety of symptoms. The environment and genetics also play a role in the development of autism spectrum disorder but the exact cause of autism spectrum disorder is not yet known.

Symptoms of autism spectrum disorder:

Your child may not be able to respond when called by his or her name by 12 months age.
Will avoid eye contact and also have the desire to stay alone.
Have trouble understanding or relating to other people or talk about their own feelings.
Delayed speech and language skills which would affect the ability to speak.
Show unusual reaction to sound, smell, taste or feelings.
Answering questions with unrelated answers that have no meaning or link.
Prefer to play alone and would avoid physical contact.

Diagnosis of Autism Spectrum Disorder:

Comprehensive Diagnostic Evaluation   The behavior of your child and development is first studied by the doctor in detail. The tests include genetic testing, neurological testing, hearing and vision testing among others. Doctors may also suggest other specialized tests in certain cases.
Developmental Screening   The development of your child s basic learning skills with respect to the age is checked. The doctor checks for some delays in the progress and will also monitor movement, behavior and speaking progress of the child. Some additional checks are also done for low birth weight, premature birth among other things.
Treatment:

Applied behavioral analysis   This is a notable treatment and widely accepted by doctors all over the world. ABA is known to encourage positive behaviors and improves a variety of skills in a child.
Occupational Therapy   Teaches the skills to live independently like eating, dressing and social skills. This can help people afflicted by autism spectrum disorders to lead a normal life within the society and thus relate to as well as interact with other people.
Speech therapy   It improves and focuses primarily on communication skills and also uses picture boards and gestures to improve the abilities and induce learning skills.

Autism Spectrum Disorder - How To Diagnose It?

Migraine is a severe form of headache wherein, the excruciating pain is accompanied by an extreme sensitivity to sound and light; you also experience nausea. The headaches usually affect either side of the head and are throbbing in nature. Hot flashes, numbness of limbs and blind spots in the eye; these are often considered as warnings. In certain cases, migraines can cause blackouts that can range from a few seconds to a few minutes.

Migraine occurs in four stages:

Pro-drome (symptom indicative of an onset of an illness)
Aura (visual auras including blurred vision)
Headache
Post-drome (the residual effects of migraine characterized by fatigue and lethargy)
But the occurrence of these stages varies across individuals. The causes of migraines aren t specifically understood. It may be due to the interaction of the brain stem with the trigeminal nerve, which is an important pain pathway of the brain. Imbalances in hormonal levels or in the levels of neurotransmitters such as serotonin may also prove to be a causal factor.

Symptoms

Migraine may be triggered due to stress, physical exertion, and excess intake of alcohol or food additives such as MSG (Monosodium Glutamate). Changes in the environment and sleeping patterns may also be probable culprits.

Migraine can be easily distinguished from regular headaches, given the fact that migraines last longer and are rather severe in nature with pain felt in one part of the head. Most people experience the  Aura stage where they have visual flashes right before headache. Nausea, eye pain or sensitivity to light and sound are other factors helpful in distinguishing migraine from other headaches.

Symptoms can occur a while before headache, immediately before headache, during headache and after headache. Although not all migraines are the same.

Typical symptoms include:

Moderate to severe pain, usually confined to one side of the head during an attack, but can occur on either side of the head
The pain is usually a severe, throbbing, pulsing pain
Increasing pain during physical activity
Inability to perform regular activities due to pain
Feeling sick and physically being sick
Increased sensitivity to light and sound, relieved by lying quietly in a darkened room
Some people experience other symptoms such as sweating, temperature changes, tummy ache and diarrhea.
Complications in migraine may include:

Chronic migraine which last up to 15 days or more
Status Migrainosus where the attacks last for over 3 days
Migrainous infarction where the aura lasts longer than it should, cutting blood supply to the brain. 
If you wish to discuss about any specific problem, you can consult a neurologist.
