CIRAANO: Multimodal exploration (including radiopharmaceuticals Amyvid® and Tauvid®) of theater actors, memory athletes, and patients with various memory pathologies: evaluation of mnesic strategies and their cerebral substrates, and contribution to the treatment of memory pathologies.
This research, called CIRAANO, is studying memory in various groups of people. This includes stage actors, people known as 'memory athletes' who have exceptional memories, and patients experiencing different memory issues such as Alzheimer's disease or problems caused by alcohol. Researchers want to understand how different memory techniques work in the brain. They'll use special brain scans, including some that look at specific proteins linked to memory problems, to measure brain volume and activity. The aim is to learn more about the brain's memory systems and how this knowledge could lead to better ways to help people with memory challenges. It's a combined Phase II and III study, meaning it's well into its research stages.
At a glance
What is this study about?
The CIRAANO study is exploring the fascinating world of memory. Researchers want to understand how our brains manage and store information. To do this, they are looking at a wide range of people: those with excellent memories like stage actors and 'memory athletes,' and individuals facing memory difficulties due to conditions such as Alzheimer's disease, Lewy Body Dementia, or issues linked to alcohol use. By comparing these different groups, the study hopes to uncover the brain's secrets behind strong memory skills and the changes that happen when memory is affected.
To achieve this, the study uses advanced brain imaging techniques. This includes MRI scans, which take detailed pictures of brain structures, and special PET scans. These PET scans use very tiny amounts of harmless radioactive tracers, called radiopharmaceuticals (like Amyvid® and Tauvid®), which help researchers see specific things in the brain, such as certain proteins that can build up in conditions like Alzheimer's. By measuring brain volume and how different parts of the brain are working, scientists aim to learn more about the physical and functional aspects of memory in different parts of the brain.
The ultimate goal of this research is to gain a deeper understanding of memory strategies and their impact on the brain. This knowledge could be crucial in developing new ways to help treat or manage various memory problems. It's an important step towards improving the lives of individuals struggling with memory conditions.
Key takeaways
- This study explores memory in diverse groups, from actors to those with memory conditions.
- It uses advanced brain scans (MRI and PET) to observe brain structure and activity.
- Researchers are looking for insights into how memory works and how it can be affected by illness.
- The findings could help develop better ways to support people with memory challenges.
- Participation involves various assessments and scans, with no new medications tested.
- It's a combined Phase II and III study, indicating advanced research.
Who may be eligible?
To be considered for this study, you need to be at least 18 years old. The researchers are looking for both men and women to take part.
They are particularly interested in hearing from people who fit into certain groups: stage actors, 'memory athletes' (people with exceptional memory skills), and individuals who have specific memory conditions like Semantic Variant Primary Progressive Aphasia, Alcohol Use Disorder, specific forms of amnesia, narcolepsy, Alzheimer's, or Lewy Body Dementia.
Because this study focuses on specific memory conditions and certain unique groups, there will be strict guidelines about who can join. The research team will review your medical history and other relevant information to see if you meet all the necessary criteria for participation.
- Are you 18 years old or older?
- Do you have a diagnosis of Alzheimer's, Lewy Body Dementia, Alcohol Use Disorder, Narcolepsy, or a specific type of amnesia or progressive aphasia?
- Are you a stage actor or a recognised 'memory athlete'?
- (If you have a memory condition) are you generally in good enough health to attend appointments and undergo scans?
- Have you discussed your interest with your doctor to make sure it's suitable for you?
This is a guide only — the research team will confirm whether you can take part.
What does participation involve?
If you join the CIRAANO study, you'll undergo several assessments. The main part of the study involves various brain scans, including MRI scans to look at the structure of your brain and special PET scans using substances like Amyvid® and Tauvid® to detect specific brain changes. These scans will help researchers understand how your brain works. You will also complete a number of detailed memory tests and questionnaires about your lifestyle, sleep, and feelings.
For some participants, especially actors or memory athletes, there might be specific evaluations related to your field, such as details about your theatre experience or memory competition rankings. The study involves different visits for these examinations. Your participation will last for the period required to complete all these assessments. The study does not involve taking new medications, but rather observing brain activity and structural changes using various imaging techniques.
