You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]

Treatment Treatment Options: There is no beneficial treatment for the neurological disease but physical therapy, speech therapy, and sometimes special education can be helpful. [disorders.eyes.arizona.edu]

Management and treatment In the absence of specific treatments to slow or stop disease progression, care is supportive. For example, parkinsonism, restless legs syndrome, spasticity, sleep disorders and depression can be treated pharmacologically. [orpha.net]
