Batten Disease

(Neuronal Ceroid Lipofuscinosis)

Definition

Batten disease is the most common form of a group of rare disorders known as neuronal ceroid lipofuscinoses (NCLs). Batten disease is an inherited genetic disorder that causes a build-up of lipopigments in the body’s tissue. Batten disease refers to a juvenile form of NCL, but the other forms of NCL can also be referred to as Batten disease. The forms of NCL include:
  • Infantile NCL
  • Late infantile NCL
  • Juvenile NCL
  • Adult NCL

Causes

Batten disease is caused by abnormalities in genes that are involved with the production and use of certain body proteins. The disease results in a build-up of fats and proteins called lipopigments in the cells of the brain, eyes, skin, and other tissues.Researchers have made progress in identifying the defective enzymes and mutated genes that underlie these disorders, but it is not yet known exactly how the gene mutations cause this build-up of lipopigments.

Risk Factors

Since Batten disease is an inherited condition, people at risk include:
  • Children of parents with Batten disease
  • Children of parents not afflicted with Batten disease, but who carry the abnormal genes that cause the disease

Symptoms

Symptoms of Batten disease include the following:
  • Vision loss and blindness
  • Muscle incoordination
  • Intellectual disability or decreasing mental function after a period of normal development
  • Emotional disturbances or difficulties
  • Seizures
  • Muscle spasms
  • Deterioration of muscle tone
  • Movement problems
Symptoms of Batten disease are similar in each type of the disease. However, the time of appearance, severity, and rate of progression of symptoms can vary depending on the type of the disease. For example:Infantile NCL (Santavuori-Haltia disease)—Symptoms begin to appear between 6 months-2 years of age and progress rapidly. Children with this type generally live until age 5, though some survive in a vegetative state a few years longer.Late infantile NCL (Jansky-Bielschowsky disease)—Symptoms begin to appear between 2-4 years of age and progress rapidly. Children with this type usually live until ages 8-12.Juvenile NCL (Spielmeyer-Vogt-Sjogren-Batten disease)—Symptoms begin to appear between 5-8 years of age and progress less rapidly. Those afflicted usually live until their late teens or early 20s; and in some cases, into their 30s.Adult NCL (Kufs disease or Party's disease)—Symptoms usually begin to appear before 40 years of age. Symptoms progress slowly and are usually milder. However, this form of the disease usually does shorten a person's life span.

A systematic review found that participants given chewing gum after abdominal surgery may have a faster return to normal for their digestive system. Unfortunately, the quality of trials is low and more research will need to be done before this simple solution is confirmed.
