Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals diagnosed with Alzheimer's Disease, Dementia with Lewy Bodies, Mild Cognitive Impairment, or cognitively normal individuals with a good grasp of English.
✕Probably not a fit
Patients with severe dementia, significant mental illnesses, or conditions affecting metabolism or haemodynamics may not benefit from this study.

What this trial studies
This observational study aims to explore the neurovascular and neurometabolic changes associated with dementia using Near-Infrared Spectroscopy (NIRS), a non-invasive imaging technique. It will involve 200 participants, including patients with Alzheimer's Disease, Dementia with Lewy Bodies, Mild Cognitive Impairment, and healthy controls. Participants will undergo cognitive testing and NIRS scans to assess brain oxygenation and metabolism. The study is conducted by the University of Cambridge and aims to improve understanding of dementia's impact on brain function.
Why it matters
Potential benefit: If successful, this study could lead to better diagnostic tools and monitoring methods for dementia, enhancing patient care.
How similar studies have gone: While NIRS is a promising technique, its application in dementia research is still emerging, and this study represents a novel approach.
