Due to the important role MAO-A plays in maintaining a balance of various neurotransmitters in the digestive and central nervous system, as well as its production of ROS, an imbalance of MAO-A may result in any of several diseases. For example, postpartum depression is a moderate to severe form of depression that occurs as the result of an excess of MAO-A in the brain that some women experience after childbirth [http://www.mpg.de]. In research conducted by Julia Sacher of the Max Planck Institute for Human Cognitive and Brain Sciences, it was concluded that the levels of MAO-A in women with postpartum depression are about 40% greater than those of average women.

Brunner's syndrome (BRUNS) is a disease associated with a mutation in the MAOA gene that results in a deficiency of MAO-A and as a result causes mild intellectual disability and aggressive behavior in males. Female heterzygotes for this mutation exhibit no mental retardation or aggressive behavior [https://ghr.nlm.nih.gov/gene/MAOA#conditions].
