Focused Ultrasound For Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Focused Ultrasound (FUS) is a non-invasive therapeutic technology that uses acoustic energy to precisely target brain regions for treatment of neurodegenerative diseases. It offers a unique combination of thermal ablation, blood-brain barrier (BBB) opening, and neuromodulation without surgical intervention. [1]
| Condition | Target | Evidence | [2]
|-----------|--------|----------| [3]
| Parkinson's Disease (tremor) | VIM thalamus | FDA approved | [4]
| Parkinson's Disease (bradykinesia) | STN, GPi | Phase III | [5]
| Essential Tremor | VIM thalamus | FDA approved | [6]
| Dystonia | GPi, STN | Phase II/III | [7]
| Combination | Rationale |
|---|---|
| FUS + Anti-amyloid antibodies | Enhanced Aβ clearance |
| FUS + Chemotherapy | Better brain tumor delivery |
| FUS + Gene therapy | AAV delivery across BBB |
| FUS + Immunotherapy | Enhanced CNS immune response |
The study of Focused Ultrasound For Neurodegeneration has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
