What are Seizures?
Seizures are symptoms of a brain problem. They happen because of sudden, abnormal excessive or synchronous neuronal activity in the brain.
How do they look like?
Seizures can cause involuntary changes in body movement or function, sensation, awareness, or behavior. They are often associated with a sudden and involuntary contraction of a group of muscles and loss of consciousness.
Seizures can be provoked by acute hypoxemic episodes or can in
some affected individuals occur unprovoked.
Optimal oxygenation and ventilation in CCHS patients reduces the chance for hypoxemic episodes but nevertheless in individuals with more severe forms of CCHS seizures may progress to persistent seizures disorder requiring anticonvulsive prophylaxis.
Can my child achieve normal intelectual functioning ?
Most of children with CCHS attend regular classes in regular
schools. However some affected individuals have significant
learning disabilities requiring special education classes.
Normal intellectual function appears to be associated with an early diagnosis and optimal ventilatory support.
Regular and comprehensive intelectual testing can identify the problem and enable aggressive educational intervention that together with optimal ventilatory management can assure maximalization of child's neurocognitive potential with a good quality of life.
What about his/her motor Motor developmetdevelopmental
It is a great chance that your child will archieve all motor developmental milestones in time but many CCHS infants present with lower muscular tone and/or major motor developmental delay needing inclusion of different neurophysiotheapeutical programs.
CCHS patients frequently exhibit vision abnormalities reflecting neural control of eye function. Most have narrow pupils that react poorly to light. They can also have strabismus of various type and therefore problems with convergence on near looking
Some CCHS individuals can present hearing problems. These may be related to deficits in periferal or central neural hearing pathways. It is important to diagnose hearing deficits early in the course of the disease to facilitate proper speech development in CCHS children that might be influenced by itself due to the need for the tracheostomy
