Children with epilepsy may have seizures only once in a while, or every day. Though seizures can be scary for parents and caregivers, they aren't painful and are usually brief.
|
|
A seizure results from a sudden rush of abnormal electrical signals in the brain. Symptoms may range from a minor daze to uncontrollable muscle spasms (convulsion). In some cases, the victim may even lose consciousness. A seizure can be caused by a high fever, head injury, drug reaction, or condition such as epilepsy.

Detailed information on hearing loss in babies According to the National Institutes of Health (NIH), nearly 12,000 babies are born each year in the United States with a hearing impairment. It is estimated that serious hearing loss occurs in about one to three of every 1,000 healthy newborns, and in two to four of every 100 babies in newborn intensive care units. Without screening or testing, hearing loss may not be noticed until the baby is more than 1 year old. If hearing loss is not detected until later years, there will not be stimulation of the brain's hearing centers. This can affect the maturation and development of hearing, and can delay speech and language. Social and emotional development and success in school may also be affected.

As you age, some hearing loss is normal. You lose more than the ability to hear how loud a sound is. You also lose the ability to hear certain types of sounds. For example, you might not be able to hear some of the high-pitched sounds of a child's voice.

Detailed information on noise-induced hearing loss When the ears are exposed to extremely loud noises, or to prolonged loud noises, inner ear structures can be damaged, leading to noise-induced hearing loss. Noise-induced hearing loss is quite common, affecting about one-third of the nearly 30 million Americans who suffer from hearing loss.

Detailed information on hearing loss in babies Hearing loss in babies occurs infrequently in the United States. However, without screening or testing, hearing loss may not be noticed until the baby is more than one year old. If hearing loss is not detected until later years, there will not be stimulation of the brain's hearing centers. This can affect the maturation and development of hearing, and can delay speech and language. Social and emotional development and success in school may also be affected.
