sentences:  TMS has shown potential with neurologic conditions such as Alzheimer's disease, amyotrophic lateral sclerosis, persistent vegetative states, epilepsy, stroke related disability, tinnitus, multiple sclerosis, schizophrenia, and traumatic brain injury.With Parkinson's disease, early results suggest that low frequency stimulation may have an effect on medication associated dyskinesia, and that high frequency stimulation improves motor function.The most effective treatment protocols appear to involve high frequency stimulation of the motor cortex, particularly on the dominant side, but with more variable results for treatment of the dorsolateral prefrontal cortex.
