Validation of the Performance of the French Version of the Cerebellar Cognitive-Affective Syndrome Scale (CCASS) as a Screening Test for Cerebellar Cognitive-affective Syndrome: a National Multicenter Study
This study is looking at a new French questionnaire called the Cerebellar Cognitive-Affective Syndrome Scale (CCASS). This questionnaire is designed to screen for a condition called Cerebellar Cognitive-Affective Syndrome (CCAS). People with CCAS have difficulties with thinking, planning, language, understanding visual information, and emotions, all linked to an issue with a part of their brain called the cerebellum. Researchers want to check if this new questionnaire is good at spotting these problems early on. They will compare a specific scoring version of the questionnaire against a more thorough set of tests to see if it correctly identifies people with CCAS. The study also aims to look at different versions of the questionnaire and how easy it is to use.
At a glance
What is this study about?
Imagine your brain is like a highly organised team, and the cerebellum is an important player that helps with movement and balance. But it's also involved in thinking, language, emotions, and how you behave. When this part of the brain has a problem, it can lead to something called Cerebellar Cognitive-Affective Syndrome (CCAS). This can cause difficulties with memory, problem-solving, speaking, recognising objects, and even managing feelings.
Currently, diagnosing CCAS can involve a lot of detailed and sometimes lengthy tests. This study is exciting because it's testing a new, simpler questionnaire, the French version of the Cerebellar Cognitive-Affective Syndrome Scale (CCASS). Think of it like a quick check-up. The researchers want to see if this quick check-up is good at picking up on the signs of CCAS.
The main goal is to find out if this questionnaire can accurately identify people who have CCAS, similar to how a more in-depth set of tests would. They will compare the results from the questionnaire with these more detailed assessments. If the questionnaire works well, it could become a useful tool for doctors to quickly screen people for CCAS, helping them get the right support sooner.
Key takeaways
- Researchers are testing a new questionnaire for Cerebellar Cognitive-Affective Syndrome (CCAS).
- The study aims to see how accurately this French questionnaire identifies people with CCAS.
- Participation involves completing questionnaires and detailed thinking/memory tests.
- Your involvement could help improve future diagnosis for others.
- You can stop participating at any time you wish.
Who may be eligible?
To join this study, you need to be an adult (18 years or older) and speak French. You must also have a problem with your cerebellum, which is a part of your brain, whether it's something you were born with or something that developed over time. You should also be part of a social security scheme, which means your healthcare is covered in France.
You cannot take part if you have other ongoing brain illnesses not related to your cerebellum, or if you regularly drink too much alcohol, or use other harmful substances. You also can't join if you are blind, deaf or mute and can't understand instructions, or if you are in prison or under certain legal restrictions.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Do you speak French?
- Do you have a known problem with your cerebellum?
- Are you covered by a social security healthcare scheme in France?
- Do you have any other significant ongoing brain conditions (not related to your cerebellum)?
- Can you see and hear well enough to understand instructions?
What does participation involve?
If you decide to take part, the first step is a screening visit where the research team will explain everything and make sure you meet the study requirements. If you do, your next medical appointment will include an 'inclusion visit'. During this visit, a specialist called a neuropsychologist will ask you to complete the CCASS questionnaire. They will start with the main version (1A), and then after about 30 minutes, you'll do another version (1B, 1C, or 1D).
To make sure the scoring is accurate, a second neuropsychologist will also be in the room, quietly observing and scoring your answers independently. A few days after these questionnaires (within 7 days), you will have a more thorough set of thinking and memory tests with a different specialist. The study is running in several hospitals across France, including Mulhouse, Paris, Nancy, and Colmar. If your questionnaire or other tests are not fully completed for any reason, you might be asked to redo them.

Common questions
What is Cerebellar Cognitive-Affective Syndrome (CCAS)?
It's a condition where problems with a part of the brain called the cerebellum lead to difficulties with thinking, language, emotions, and how a person behaves.
What is the Cerebellar Cognitive-Affective Syndrome Scale (CCASS)?
It's a new questionnaire designed to quickly check for signs of CCAS. This study is testing how well the French version of it works.
Will I receive any new treatment in this study?
No, this study is about testing a questionnaire, not a new medicine or treatment. It will help doctors in the future.
How long will I need to be involved?
You'll have an inclusion visit where you complete questionnaires, and then a more detailed assessment within 7 days. There are no ongoing follow-up visits after that.
Can I leave the study if I change my mind?
Yes, you can withdraw from the study at any point without it affecting your usual medical care.
