Collection of biological samples from patients with rare neurological diseases

Prospective Collection of Biological Samples From Patients With Rare Neurological Diseases

University Hospital, Toulouse · NCT04698421

This study is trying to collect biological samples from people with rare neurological diseases to see if they can find new markers that help diagnose and treat these conditions.

What this trial studies

This project aims to enhance the collection of biological samples from patients suffering from rare neurological disorders with known or suspected autoimmune origins. By gathering these samples, the study seeks to identify new biomarkers that can aid in the diagnosis and treatment of these conditions. The focus is on disorders such as autoimmune encephalitis and paraneoplastic neurological syndromes, where the immune system plays a critical role. The collected samples will be made available to the medical and scientific communities to foster the development of new therapeutic strategies.

Who should consider this trial

Good fit: Ideal candidates include patients of all ages with neurological disorders that have known or probable autoimmune involvement.

Not a fit: Patients with neurological damage that is not autoimmune in nature or those with known anemia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and prognostic tools for patients with rare neurological diseases.

How similar studies have performed: While the approach of collecting biological samples for autoimmune neurological disorders is established, the specific focus on rare conditions may present novel insights.
