In vivo PET of synaptic density in cognitive disorders: prospective evaluation of neuronal dysfunction and relation to symptomatology.
This research study is looking at how the brain's connections, called synapses, change in people experiencing memory problems or other brain conditions like Alzheimer's disease. We're using a special type of brain scan, similar to a PET scan, to see these tiny connections. The main goal is to understand why these brain conditions develop and how these changes in brain connections lead to the symptoms people experience. By learning more about these changes, we hope to discover new ways to diagnose and treat these conditions in the future, ultimately improving care for people affected by them. This is an early-stage study, helping us learn more about the brain itself.
At a glance
What is this study about?
Imagine your brain is like a city with many roads and bridges; these connections are vital for everything you do, from remembering names to planning your day. In this study, we're looking at something called 'synaptic density.' Think of synapses as the tiny junctions where brain cells communicate with each other – they are the 'bridges' of your brain. When these connections change or are lost, it can affect how your brain works, leading to problems with memory, thinking, and even mood.
We're interested in how these synaptic connections are affected in people who have different types of cognitive disorders. This includes conditions like Alzheimer's disease, which is known for memory loss, and other conditions like Frontotemporal dementia and Lewy Body Disease, which can affect personality, behaviour, and movement. We're also looking at how these changes might relate to mental health conditions.
The main aim of this research is to see if we can measure these changes in synaptic density using a special type of brain scan (a 'PET' scan) while people are alive. By understanding how these brain connections change and how these changes lead to the symptoms people experience, we hope to find clues that could lead to earlier diagnosis and potentially new treatments down the line. It's an important step in unlocking the mysteries of the brain and developing better ways to help people living with these conditions.
Key takeaways
- This study uses special brain scans to look at brain connections (synapses).
- It aims to understand how brain conditions like Alzheimer's affect these connections.
- The findings could help develop better diagnoses and treatments in the future.
- It's an early-stage research study, not a direct treatment.
- Anyone over 18 with relevant conditions may be eligible.
- Participation includes brain scans and assessments.
Who may be eligible?
This study is open to adults aged 18 and over, with no upper age limit. We are looking for people who have been diagnosed with certain cognitive disorders, which are conditions that affect memory, thinking, or behaviour, such as Alzheimer's disease, Frontotemporal dementia, or Lewy Body Disease. We are also interested in people with certain psychiatric (mental health) conditions.
You would not be able to join if you have certain other medical conditions or are taking specific medications that might interfere with the study. The research team will carefully check your medical history to make sure that taking part is safe for you and that the study results will be clear.
Both men and women are welcome to take part in this study. The research team will discuss all the requirements with you and answer any questions you have to help you understand if this study is right for you.
- Are you 18 years old or older?
- Have you been diagnosed with a memory problem or certain brain condition (like Alzheimer's or Lewy Body Disease)?
- Are you able to attend appointments at the research centre?
- Are you willing to undergo research brain scans (PET scans)?
This is a guide only — the research team will confirm whether you can take part.
What does participation involve?
Taking part in this study would involve attending one or more visits to a clinic or research centre. During these visits, you would have a special type of brain scan called a PET scan. This scan helps us look at the brain's connections. You might also have other assessments, such as memory tests or questionnaires, to understand your symptoms and how you are feeling.
This is a 'Human Pharmacology (Phase I)' study, which means it's an early study focused on understanding how a new method or treatment works rather than testing if it completely cures a condition. There are no new medications being tested in this specific study; instead, we are developing a new way to look at the brain. The total time you would be involved in the study would be explained to you by the research team, but typically, these early phase studies might involve a few visits over a shorter period.

Common questions
What is a PET scan?
A PET scan is a special type of brain scan that uses a tiny amount of a safe, mildly radioactive substance to create detailed pictures of what's happening inside your brain.
What are 'synapses'?
Synapses are like tiny communication points between brain cells, allowing them to send messages to each other. They're essential for thinking, learning, and remembering.
Will this study cure my condition?
No, this is an early-stage study focused on understanding brain changes, not on providing a cure or direct treatment. Your participation will help future research.
How long will I be involved in the study?
The total duration of your participation will be discussed by the research team, but it typically involves a few visits for scans and assessments.
Can I stop participating if I want to?
Yes, you are free to withdraw from the study at any time, for any reason, without it affecting your medical care.
