Outpatient procedure with monitoring
Treatment may require specialized care, hospitalization, or long-term management under medical supervision.
Functional maintenance therapy
Physical and occupational therapy focus on preserving existing function and adapting to new limitations. Therapy includes exercises for strength, balance, and coordination along with training in use of assistive devices.
Additional treatment options
Disease progression monitoring
Comprehensive monitoring through regular neurological examinations, visual assessments, and developmental evaluations tracks disease progression and informs treatment adjustments. Documentation of changes helps families understand the disease course.
monitoringEnteral nutrition planning
