Variable Response
Cohort Name Neuroimaging of Inflammation in MemoRy and Other Disorders (the NIMROD Study)
Cohort Acronym NIMROD
Study Overview The NIMROD (Neuroimaging of Inflammation in Memory and Other Disorders) study aims to understand the role of inflammation in several forms of dementia, memory loss and depression (Alzheimer's disease, AD, dementia with Lewy bodies, DLB, progressive supranuclear palsy, PSP, frontotemporal dementia, FTD, late life depression, LLD, vascular dementia, VaD, mild cognitive impairment, MCI). The study has been set up to investigate the extent and pattern of neuroinflammation in these disorders in relation to: key clinical symptoms, including cognitive impairment, peripheral markers of neuroinflammation, including cytokine levels and state-of-the-art immunoprofiling, structural changes on MRI, including atrophy and vascular (white matter lesion) changes, the extent and pattern of brain amyloid deposition as assessed with amyloid PET imaging, the extent and pattern of tau deposition as revealed with PET. A further aim is to investigate if neuroinflammation can predict subsequent clinical course, including cognitive and functional decline.
#Subjects at Baseline Currently 145: 13 controls, 12 controls for AV-1451 imaging, 22 MCI, 19 AD, 18 DLB, 6 LLD, 6 FTD, 2 VaD, 19 PSP, 1 unconfirmed (MCI) and 27 who have withdrawn but whose data remains in the study.

Inclusion criteria Over 50 years old, Grasp of English, MMSE>12 for patients, MMSE>26 for controls. AD: meet diagnostic criteria for probable AD (McKhann et al., 2011), MCI: MMSE >24 but with memory impairment beyond that expected for age and education (Petersen et al., 1999), Lewy Body Dementia: criteria for dementia with LB and those with PD (McKeith et al., 2005), PSP: Litvan et al., 1996 clinical diagnostic criteria with the relaxation of the falls criterion to falls within 3 years rather than 1 year, as suggested by the NNIPPS-PSP study group), Later life depression: DSM-IV crietria, FTD: Clinical criteria (according to Rascovsky et al., 2011 and Gorno-Tempini et al., 2011), Vascular Dementia: diagnosed with vascular dementia.
Exclusion criteria Concurrent major psychiatric disorder, Severe dementia, MMSE <12, Severe physical illness or co-morbidity, Prostheses or other implants that would limit the safety or value of scanning, Past diagnosis with PD (unless in the Progressive Supranuclear Palsy or Lewy Body Dementia cohort), Pregnant or breastfeeding, History of or current consumption of excessive alcohol and or recreational drugs.
