Clinical, Electrophysiological and Biological Diagnostic Criteria of Sensory Neuronopathies

Stopped: Start of a new study concerning the same patients

France80 participantsStarted 2010-05

Plain-language summary

The diagnosis of sensory neuronopathy is difficult to establish because the only certainty criterion is based on the detection of specific lesions in the posterior spinal ganglion which is usually not possible. There is to date no clinical and electrophysiological criteria or validated biomarker for the diagnosis of this type of neuropathy. In a retrospective study, we analyzed the files of patients with peripheral sensory neuronopathy certain and established clinical and electrophysiological diagnostic criteria for sensitive neuronopathy. We therefore wish now validate these criteria and investigate possible associated antibodies on a prospective cohort of patients.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * A :Patients Male or female patient aged 18 years or more with a clinically pure sensory neuropathy, abnormal ENMG in sensory nerves in more than one limb and complete etiological assessment allowing a diagnosis of sensory neuronopathy. B :Controls Male or female patient aged 18 years or more with a clinically pure sensory neuropathy, abnormal ENMG in sensory nerves in more than one limb and complete etiological assessment allowing a diagnosis of sensory neuropathy excluding a neuronopathy. Exclusion Criteria: * Patient with a sensory-motor neuropathy or incomplete clinical evaluation

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
