Study summary

Cerebellar ataxia is a form of ataxia originating in the cerebellum. Cerebellar ataxia can occur as a result of many diseases and may present with symptoms of an inability to coordinate balance, gait, extremity and eye movements. To understand the clinical and genetic characteristics of cerebellar ataxia, we establish a registered cohort to follow up Chinese patients with cerebellar ataxia.

Study population

Patients with cerebellar ataxia who are diagnosed by tow neurologists in the Organization in South-East China for Cerebellar Ataxia Research (OSCCAR) from the First Affiliated Hospital of Fujian Medical University.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with cerebellar ataxia based on the diagnoses of tow neurologists
  • Relatives of patients with cerebellar ataxia
  • Unrelated healthy controls
  • Participants or legal guardian(s) willing and able to complete the process

Exclusion criteria

Exclusion Criteria:

  • Participants are unable to comply with trial procedures and visit schedule
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 12, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
