What are Pediatric Neurotransmitter Diseases?
“Pediatric Neurotransmitter Disease” is an umbrella term for genetic disorders that affect the synthesis, metabolism and catabolism of neurotransmitters in children. These inborn errors of metabolism affect the central nervous system in children and if left untreated can lead to severely compromised neurological function. The symptoms of some pediatric neurotransmitter diseases can be completely treated whereas in other pediatric neurotransmitter diseases treatment can sometimes improve quality of life.
Pediatric Neurotransmitter Diseases are distinguishable by their respective affected neurotransmitters. Two categories presently exist amongst pediatric neurotransmitter diseases and symptoms and treatments are determined by the specific disease.
