Eric Marsh, MD, PhD, is an attending pediatric neurologist in the Division of Neurology at Children’s Hospital of Philadelphia (CHOP). He specializes in diagnosing and treating children with developmental epilepsies, epilepsy, infantile spasm and malformations of cortical development.

Dr. Marsh’s philosophy of care centers around helping families feel heard and informed.

“It’s important that families are listened to, their concerns are taken seriously and the issues and conditions they face are explained to them to the best of our abilities,” he says.

In addition to his role at CHOP, Dr. Marsh is an associate professor of neurology at the Perelman School of Medicine at the University of Pennsylvania.

Dr. Marsh has long been fascinated by the workings of the brain and how its billions of neurons can lead to neurological diseases when not functioning properly. This interest has driven his research into genetic epilepsies and genetic neurodevelopmental disorders.

“Understanding these disorders can lead to a better grasp of how the brain works and can lead to novel treatments and cures for these conditions,” he says.

Much of Dr. Marsh’s research focuses on mutations in the ARX gene, which cause epilepsy and other diseases. He is also studying the clinical presentations of Rett syndrome, Dravet syndrome and Lennox-Gastaut syndrome, CDKL5 syndrome and related disorders, and is involved in a number of clinical trials for novel therapeutics.

“There is an emergence of cell-, RNA- and DNA-based therapies as well as pathway-directed pharmaceutical approaches to treating these difficult to treat conditions,” he says. “I feel that a better clinical understanding of these conditions using new technologies to track and monitor neurological function will allow for novel therapies to improve patients’ lives.”

Research Interests

My primary research interest is in understanding the relationship between interneuronal development and altered excitability that leads to epilepsy. This pattern is primarily seen in children with malformations of cortical development but also a number of emerging set of diseases called interneuronopathies. We are studying how loss of a gene important for interneuronal development, the gene ARX, can lead to changes in excitability and development of epilepsy. I am also interested in analyzing intracranial EEG recordings to learn how to better localized the epileptic zone and network. These studies will improve how patients are cared for during epilepsy surgery and improve the understanding of how abnormal brain generates seizures.
