Imaging lithium in Alzheimer's disease
This study aims to understand how lithium, a drug used for mood disorders, affects the brain in people with Alzheimer's disease and healthy individuals. Lithium has shown promise in protecting brain cells and potentially slowing down Alzheimer's. Researchers have developed a new, safe way to measure lithium levels in the brain using a special MRI scan. This study will use this scan to see where lithium goes in the brain and if its effects vary between healthy people and those with Alzheimer's. Participants will take low-dose lithium for two weeks and have three MRI scans. The findings will help decide the best dose for future Alzheimer's treatments and make brain scanning easier for people with dementia.

על מה המחקר הזה?
This study, called 'Imaging lithium in Alzheimer's disease,' is trying to understand more about how a medication called lithium works in the brain. Lithium has been used for many years to treat mood disorders, and there's some evidence that it might also help protect the brain and even reduce the risk of dementia. For people with Alzheimer's disease, early signs suggest that even small amounts of lithium might slow down how quickly the condition progresses.
The researchers have found a new and safe way to measure lithium levels directly in the brain using a special type of MRI scan. This is exciting because it means they can see exactly where the lithium goes and how much gets there. They want to combine these special lithium scans with regular MRI scans to get a complete picture of how lithium affects the brain at different doses. They'll also compare these effects between healthy people and those living with dementia.
The main goal is to use this information to help design better future studies. By understanding how lithium behaves in the brain, they hope to figure out the best dose to use for new treatments for Alzheimer's disease. They also want to learn how easy it is for people with dementia to have these special brain scans, which is important for future research.

מי עשוי להיות זכאי?
To join this study, you need to be between 50 and 80 years old. If you're a healthy volunteer, you shouldn't have a history of any major mental health conditions or nerve disorders, and your memory should be generally unaffected.
If you have Alzheimer's disease, your diagnosis needs to be confirmed by two doctors, and your condition should be mild to moderate. You also shouldn't have had bipolar disorder, severe depression, or other major mental health conditions apart from your Alzheimer's.
There are also some reasons you wouldn't be able to join. For example, if you have certain health problems like kidney issues or epilepsy, or if you have metal implants in your body (like a pacemaker), you wouldn't be able to participate. You also can't be taking certain medications like lithium already, or some pain relievers or blood pressure medicines.

- If healthy, do you have no history of major mental or nerve conditions?
- If you have Alzheimer's, is it mild to moderate, and confirmed by two doctors?
- Do you have any metal implants or health conditions (like kidney issues) that might prevent an MRI or taking lithium?

מה כרוך בהשתתפות?
If you decide to take part in this study, you'll be asked to take a low dose of lithium medication by mouth for a total of two weeks. You'll take one dose for the first week, and then a slightly different dose for the second week. During this time, you'll also have three MRI scans of your brain, with each scan happening about one week apart. You'll need to visit the Newcastle Magnetic Resonance Centre for these scans and appointments. The entire study participation, including the medication and scans, is expected to take about three weeks.

שאלות נפוצות
What is lithium and why are you studying it for Alzheimer's?
Lithium is a medicine often used for mood problems. We're studying it because initial research suggests it might protect the brain and could slow down Alzheimer's disease.
What is an MRI scan and is it safe?
An MRI scan uses strong magnets and radio waves to create detailed images of your brain. It doesn't use radiation and is generally very safe, though it can be a bit noisy and you need to lie still.
Will I get to know my MRI results?
The study focuses on gathering information for research. While you won't typically get personal MRI results, any significant findings relevant to your health would be discussed with you.
How long will the study go on for?
The study is expected to run from August 2025 to April 2026. Your individual participation would last for about three weeks.
מי מממן את המחקר הזה?
This study is being funded by Alzheimer's Research UK, a charity dedicated to finding new ways to prevent, treat, and cure dementia.
