Definition    Return to top

Neuronal ceroid lipofuscinoses (NCLS) refers to a group of rare, inherited disorders of the nerve cells.

There are three main types of NCLS:

Causes    Return to top

NCLS is a type of neurodegenerative disorder. It involves a build-up of an abnormal material called lipofuscin in the brain. Evidence suggests that NCLS is caused by problems with the brain's ability to remove and recycle proteins.

The disorder may be seen at birth, but it is usually diagnosed much later. Children develop lack of muscle coordination (ataxia), walking problems, sight problems, retardation, and seizures. The younger the person is when the disease appears, the greater the risk for disability and early death.

Lipofuscinoses are inherited as autosomal recessive traits. That means if both parents carry the trait, each child has:

Outlook (Prognosis)    Return to top

If the disease occurs in adulthood, symptoms will be milder with no vision loss and a normal life expectancy. Those who develop the disease early can have vision problems that progress to blindness, and mental deterioration. If the disease emerges in the first year of life, death is likely by age 10.

Possible Complications    Return to top

People with the early-onset forms of the disease typically have visual impairment or blindness. Mental impairment can range from severe retardation at birth to late-onset dementia. There can be severe problems with the nerves that control muscle tone, making the muscles rigid. The person may become totally dependent on others for help with daily activities.

When to Contact a Medical Professional    Return to top

Call your health care provider if your child shows symptoms of blindness or retardation.

Prevention    Return to top

Genetic counseling is recommended if your family has a known history of NCLS. Prenatal or preimplantation genetic testing may be available depending on the specific type of disease.
