MAOA deficiency

MAOA deficiency is a condition caused by a lack or reduction of the enzyme monoamine oxidase A (MAOA), which helps break down certain chemicals in the brain, such as serotonin, norepinephrine, and dopamine. Without enough MAOA, these chemicals can accumulate, potentially affecting mood, behavior, and emotional regulation. This deficiency is genetic and can be associated with increased risk of aggressive behavior, impulsivity, or mood disorders, although not everyone with the deficiency experiences these effects. It is a complex condition influenced by genetics and environment, requiring careful medical and psychological assessment.
