  • Dr. Melita Petrossian is a fellowship-trained neurologist and movement disorders specialist and is the Director of the Pacific Movement Disorders Center located at Providence Saint John’s Health Center. Dr. Petrossian’s clinical interests and expertise are in movement disorders such as Parkinson’s disease (PD), tremor including essential tremor, dystonia, gait disorders, ataxia, myoclonus, blepharospasm, hemifacial spasm, Meige syndrome, spasticity, tics and Tourette’s syndrome. She also specializes in Parkinson’s-related conditions such as Dementia with Lewy Bodies, progressive supranuclear palsy, multiple system atrophy, corticobasal degeneration, primary freezing of gait, and Parkinson’s Disease Dementia.

    Dr. Petrossian’s focus is on a multidisciplinary approach to these movement disorders, including appropriate diagnosis utilizing the latest imaging techniques such as MRI, PET and DaTscan, optimization of medical treatment, and chemodenervation using botulinum toxin injections (e.g., Botox). In coordination with physical therapists, occupational therapists, speech therapists, and other specialists as necessary she treats motor and non-motor symptoms of PD and other movement disorders. Dr. Petrossian provides assessments for candidates for deep brain stimulation surgery for PD, essential tremor and dystonia, guides patients through the pre- and post-operative period, and creates a custom-tailored program of deep brain stimulation settings.
