David D. Song, M.D., Ph.D., is a Health Sciences Clinical Professor of Neurosciences at the University of California, Riverside (UCR) School of Medicine and board certified neurologist with UCR Health.
Dr. Song earned his medical degree from Tulane University School of Medicine, New Orleans, Louisiana. He completed his residency in neurology at the University of Colorado Health Sciences Center, Denver, Colorado. He also completed a fellowship in movement disorders and experimental therapeutics at University of Rochester Medical Center, Rochester, New York and a fellowship in Parkinson’s Disease/Parkinsonism at University of California San Diego, San Diego, California.
On Movement Disorders
Dr. Song has expertise on Movement Disorders, which include neurologic abnormalities of “moving too little”, specifically Parkinson’s Disease (PD) and other problems with gait or walking, or abnormalities of “moving too much”, abnormal involuntary movements, such as: rhythmic Tremors of all types including Essential Tremor (ET); muscle contractions or spasms (Dystonia or Spasticity); jerky movements such as Tics and Tourette’s Syndrome (TS), Chorea including Huntington’s Disease (HD), and Myoclonus; or bizarre inconsistent functional or Psychogenic movements.
On Parkinson’s Disease and Parkinson-like Syndromes
Parkinson’s disease (PD), as well as diseases that look like Parkinson’s (Parkinson-like Syndromes or “Parkinsonisms”), are gradually worsening (progressive) degenerative diseases that are currently not curable, but PD in particular is very treatable, allowing improvement of quality of life. Dr. Song is a fellowship trained expert in Parkinson’s disease and Parkinson-like syndromes and can speak on topics including diagnosis, prognosis, treatments including pharmacologic (medications) and non-pharmacologic therapies (Deep Brain Stimulation (DBS) surgery and physical therapy), and emerging therapies.
On Muscle Spasms Dystonia and Spasticity
Abnormally increased muscle tone can cause Muscle spasms, Spasticity or Dystonia, causing loss of normal control of muscles and abnormal postures and movements that can be disfiguring and/or painful. Dr. Song can speak on diagnosis and treatments including oral medications and well-established FDA approved indications for botulinum toxin injections (Botox, Xeomin, and Myobloc) for Dystonia and Spasticity, and indications for DBS in medical refractory dystonia.
On Deep Brain Stimulation (DBS)
Deep Brain Stimulation (DBS) surgery is considered when patients with Parkinson’s Disease (PD), Tremor (ET), or Dystonia are inadequately controlled with standard treatments with oral or injected medications. Furthermore, optimum treatment of complex movement disorder patients, often require a combination of both DBS and optimizing multiple medications for improvement of symptoms.
