Philosophy of Care

I believe that multi-modality interventions can be synergistic and targeted treatments can be very helpful for many disorders.

Clinical Interests

Dr. Hagerman's main areas of research are targeted treatment trials in Fragile X Syndrome (FXS), Rett Syndrome, Fragile X-associated Tremor/Ataxia Syndrome (FXTAS), and Autism Spectrum Disorder (ASD). Her clinical patients include: FXS, FXTAS, ASD, and other neurodevelopmental disorders.
