Current treatments are ineffective, with most patients dying within 3-5 years of diagnosis. The disease's exact cause is unclear, but factors such as oxidative stress and protein abnormalities are implicated. Abnormal protein deposits and neurotoxic factors in the brain and spinal cord contribute to ALS pathology. Recent research on the brain's glymphatic-lymphatic system suggests impaired waste clearance may exacerbate ALS. Restoring drainage connections between cervical lymphatic vessels and veins could potentially alleviate neurodegenerative disease progression.",[46],"Efficacy and Safety",[48],"Amyotrophic Lateral Sclerosis","NOT_YET_RECRUITING","2024-05-14",{"date":52,"type":53},"2024-05-16","ACTUAL",{"date":55,"type":42},"2024-08-01",{"date":57,"type":42},"2027-08-01",{"name":5,"class":6}]
