Frequently Asked Questions

QWhat exactly is Monoamine Oxidase A Deficiency?

Monoamine Oxidase A Deficiency is a rare genetic condition where the body lacks enough of an enzyme called monoamine oxidase A. This enzyme plays a crucial role in breaking down certain neurotransmitters in the brain, such as serotonin, norepinephrine, and dopamine. Without enough of it, these chemicals can build up, leading to various neurological and behavioral issues.

QHow do you know if someone has this deficiency?

Diagnosing Monoamine Oxidase A Deficiency typically involves a combination of genetic testing and observing symptoms. Common signs include aggressive behavior, mood swings, and other emotional disturbances. However, since these can also be symptoms of other conditions, genetic testing is key to a definitive diagnosis.
