Lateral sclerosis
MONDO:0018155Primary lateral sclerosis (PLS) is an idiopathic non-familial motor neuron disease characterized by slowly progressive upper motor neuron dysfunction leading to spasticity, mild weakness in voluntary muscle movement, hyperreflexia, and loss of motor speech production.
Also known as: PLS, adult-onset PLS, adult-onset primary lateral sclerosis, primary lateral sclerosis

Desperate patient gets experimental stem cells for rare nerve disease
Disease control Expanded access (ended)This study provides an experimental stem cell treatment (HB-adMSCs) to an 83-year-old man with Primary Lateral Sclerosis, a rare nerve disease that causes progressive muscle weakness. The patient's own banked stem cells are used, aiming to slow the disease. This is a single-patie…

Can a multiple sclerosis drug help people with rare motor neuron disease walk better?
Symptom relief OngoingThis early-stage trial tests the drug dalfampridine (Ampyra), already used for multiple sclerosis, in 35 adults with primary lateral sclerosis or upper motor neuron ALS. The main goal is to see if it safely improves walking speed, measured by a timed 25-foot walk. Researchers wil…

French-Language scale for rare nerve disease put to the test
Knowledge-focused OngoingThis study checks whether a French version of a scale called PLSFRS works well for people with primary lateral sclerosis (PLS), a rare nerve disease. Researchers will ask 80 patients to fill out the questionnaire during routine check-ups every 3 to 6 months. The goal is to see if…
