Batten Turner Syndrome is a rare genetic disorder that is characterized by progressive vision loss and neurological problems. The exact cause of the condition is unknown, but it is believed to be caused by a mutation in a gene called CLN3. Batten Turner Syndrome typically begins in childhood, and affects both males and females equally. There is currently no known cure for the condition, but treatments are available to help man  Read More

Hearing loss can affect a child’s ability to develop speech, language, and social skills. The earlier children with hearing loss start getting services, the more likely they are to reach their full potential. Hearing loss can happen when any part of the ear is not working in the usual way. Genetic factors are thought to cause more than 50% of all incidents of congenital hearing loss in children. Geneti  Read More

In addition, in some cases, a  Read More

Down syndrome is a genetic disorder and the most common autosomal chromosome abnormality in humans, where extra genetic material from chromosome 21 is transferred to a newly formed embryo. These extra genes and DNA cause changes in the development of the embryo and fetus resulting in physical and mental abnormalities. Each patient is unique and there can be great variability in the severity of symptoms.  Read More

Chromosome 9, Trisomy 9p is a rare chromosomal syndrome in which a portion of the 9th chromosome appears three times (trisomy) rather than twice in cells of the body. The trisomy may involve a portion of the short arm (9p), the entire short arm, or the short arm and a portion of the long arm (9q) of chromosome 9. (Each chromosome contains a short arm known as "p" and a long arm designated as "q.") Evidence suggests that, in many cases, associa  Read More

Epilepsy and Multiple subpial transection (MST) is a technique used to disconnect areas of the brain where seizure activity occurs. The goal of the surgery is to stop the spread of irregular electrical activity that causes seizures. The procedure may be recommended when the area of epileptic activity in the brain is not able to be resected and does not respond to medication. The surgery aims to destroy fibers that  Read More

More than 10 uncommon "progressive" epilepsies are grouped together as epilepsy, myoclonic progressive familial. The motor abilities, balance, and cognitive function of people with myoclonic progressive families deteriorate over time.Myoclonic and tonic-clonic seizures coexist in myoclonic progressive familial (rapid muscle jerks of multiple body parts). Unsteadiness, muscle rigidity (tightness of the muscles), bal  Read More

An extratemporal cortical resection is an operation to resect, or cut away, brain tissue that contains a seizure focus. Extratemporal means the tissue is located in an area of the brain other than the temporal lobe. The frontal lobe is the most common extratemporal site for seizures. In some cases, tissue may be removed from more than one area/lobe of the brain. Extratemporal cortical resection may be an option for people with epilepsy whose  Read More

Medication is usually the first line of treatment for vagus nerve stimulation (VNS). In the event that drugs are ineffective, doctors could recommend surgery or another form of treatment. 1. Medication The majority of epileptics can go epilepsy-free by using one anti-seizure medicine, commonly known as an anti-epileptic drug. A combination of drugs may help some people reduce the frequency and severity of th  Read More

A disorder called Erb's paralysis is characterized by arm numbness and lack of motion. A few of the causes behind Era's paralysis include: 1. Erb's paralysis is most frequently brought on by dystocia, which is a difficult or unusual birth or labor. It might happen, for instance, if the baby's head and neck are dragged to the side as the shoulders pass down the birth canal. 2. During a challenging birt  Read More

Febrile seizures are convulsions brought on by a fever in infants or small children. How common are febrile seizures? Approximately one in every 25 children will have at least one febrile seizure, and more than one-third of these children will have additional febrile seizures before they outgrow the tendency to have them. Febrile seizures usually occur in children between the ages of 6 months and 5 years and are particularly co  Read More
