Active clinical trials for "Spastic Paraplegia, Hereditary"

Comparing the cognitive levels of patients with SPG4 mutations to healthy controls.

The purpose of this study is to learn about rates of patient-reported disease progression in patients with motor neuron diseases (amyotrophic lateral sclerosis, progressive muscular atrophy, primary lateral sclerosis, hereditary spastic paraplegia) outside the clinical setting, and the patient-reported clinical characteristics that influence this rate of progression. All patients enrolled in CReATe Connect, a Rare Diseases Clinical Research Network (RDCRN) Contact Registry, will be invited via email to participate in this study.

Hereditary spastic paraparesis type 11 (SPG11) is caused by mutations in the SPG11 gene that produces spatacsin, a protein involved in lysosomal function.

This study will use a magnetic resonance imaging technique called nuclear magnetic spectroscopy (H-MRS) to define the pathology and progression of primary lateral sclerosis, hereditary spastic paraplegia and amyotrophic lateral sclerosis and assess the usefulness of this technique in evaluating patients' response to therapy. H-MRS will be used to examine metabolic changes in the parts of the brain and spinal cord (motor cortex and corticospinal tract) involved in movement. Normal volunteers and patients with primary lateral sclerosis, hereditary spastic paraplegia or amyotrophic lateral sclerosis between 21 and 65 years of age may be eligible for this study. Participants will have up to five H-MRS studies, including baseline and follow-up tests. For this procedure, the subject lies on a stretcher that is moved into a strong magnetic field. Earplugs are worn to muffle the loud knocking noise that occurs during switching of radio frequencies. The subject will be asked to lie still during each scan, for 1 to 8 minutes at a time. Total scanning time varies from 20 minutes to 2 hours, with most examinations lasting between 45 and 90 minutes. Communication with the medical staff is possible at all times during the scan.
