Study Finds Evidence Supporting a Trauma Subtype of Functional Neurological Disorder
Sara Paredes-Echeverri, MD, Andrew Guthrie, and David L. Perez, MD, present support for a trauma subtype of functional neurological disorder (FND) that is evident across the diagnoses of functional movement disorder and functional seizures. Its recognition might improve the selection of psychotherapy for FND patients.
Review: A New Science of Emotion and Its Implications for Functional Neurological Disorder
David L. Perez, MD, MMSc, Lisa Feldman Barrett, PhD, and colleagues recently reviewed the theory of constructed emotion and posit that deficits in the brain's predictive process of constructing emotion categories are integral to the pathogenesis of functional neurological disorder.

An Integrated Approach Aids Functional Neurological Disorder Care and Research
Massachusetts General Hospital clinician-scientists take a two-pronged approach to advance functional neurological disorder care and understanding.
White Matter Is Altered in Functional Neurological Disorder
In the first study to evaluate white matter in mixed motor subtypes of functional neurological disorder, microstructural differences were observed in brain regions implicated in emotion/salience, pain modulation and stress responses, and certain differences correlated with clinical findings.

In the Mass General Functional Neurological Disorders Clinic, Dr. Perez provides specialized, integrated neurologic and psychiatric consultations for patients experiencing motor Functional Neurological Disorders, including individuals with Psychogenic Nonepileptic Seizures, Functional Movement Disorders, and Functional Limb Weakness.
Dr. Perez is also the director of the Mass General Functional Neurology Research Group, which is dedicated to the comprehensive clinical and neurobiological investigation of motor Functional Neurological Disorders. The laboratory uses advanced structural and functional magnetic resonance imaging (MRI) techniques to investigate biomarkers of symptom severity, disease-risk, subtype and prognosis across individuals with Psychogenic Nonepileptic Seizures, Functional Movement Disorders and Functional Limb Weakness.
Dr. Perez is a dual trained and board certified neurologist-psychiatrist, and is a member of the Cognitive Behavioral Neurology, Frontotemporal/Memory Disorders and Neuropsychiatry Units at Massachusetts General Hospital.
