Description of intervention(s) / exposure
Positron Emission Tomography (PET):
- Intravenous injection, via forearm cannula, of 250MBq of 18F-FEMPA PET tracer by a qualified nuclear medicine technologist on a single occasion in a University medical imaging research facility.
- 60min recording, from time of injection, of PET data from the whole brain using a Siemens Biograph PET/MR commercial scanner, operated by a qualified nuclear medicine technologist and MR radiographer.
Magnetic Resonance Imaging (MRI):
- Noninvasive acquisition of anatomical, diffusion, perfusion, spectroscopic, and functional MRI data over 60mins, simultaneous to the PET acquisitions using a Siemens Biograph MR/PET commercial scanner, operated by a qualified MR radiographer.
Study procedures will be the same across all participants.

Statistical methods / analysis
Sample sizes were determined based on comparable studies undertaken in similar cohorts, and current standards employed in observational neuroimaging research.
Standardised uptake values, normalised to the whole brain, of the PET tracer will be calculated at every point (voxel) in the brain for each participant. Group comparisons (patients versus controls) will be undertaken using non-parametric inference with cluster-level correction for multiple comparisons across the brain.

Summary
Brief summary
Immune-responsive cells of the brain – namely microglia and astrocytes – activate in response to brain injury or pathogens. This activation leads to a local neuroinflammatory response that serves to isolate and protect the tissue, remove the noxious agent, and promote recovery. However, while beneficial in the short term, the chronic release of pro-inflammatory chemicals (cytokines and chemokines) becomes increasingly toxic, and actually begins to contribute to neuropathology in its own right. Chronic neuroinflammation is thought to play a central role in the progressive neural morbidity that underlies neurodegenerative disorders such as Huntington’s Disease (HD), Alzheimer’s Disease (AD), and Parkinson’s Disease (PD). However, there is little current understanding of the link between in vivo neuroinflammation and in vivo brain atrophy in humans, particularly as it relates to how the disease spreads to regions beyond primary sites of pathology. In this study, we will use a novel multi-modal neuroimaging approach that combines positron emission tomography (PET), magnetic resonance spectroscopy (MRS), and magnetic resonance imaging (MRI) to investigate the contribution of neuroinflammation to brain atrophy in individuals with neurodegenerative disorders. This work has direct implications for (i) developing more complete models of the pathological processes underpinning disease expression, (ii) assessing the sensitivity of neuroinflammatory measures as disease biomarkers, and (iii) providing support for (or against) the value of pursing novel disease monitoring and intervention approaches that respectively involve measuring or mitigating chronic neuroinflammatory processes.
