Background: With the more widespread use of 18F-radioligand-based amyloid-β (Aβ) PET-CT imaging, we evaluated Aβ binding and the utility of neocortical 18F-Flutemetamol standardized uptake value ratio (SUVR) as a biomarker. Objective: 18F-Flutemetamol SUVR was used to differentiate 1) mild cognitive impairment (MCI) from Alzheimer’s disease (AD), and 2) MCI from other non-AD dementias (OD). Methods: 109 patients consecutively recruited from a University memory clinic underwent clinical evaluation, neuropsychological test, MRI and 18F-Flutemetamol PET-CT. The diagnosis was made by consensus of a panel consisting of 1 neuroradiologist and 2 geriatricians. The final cohort included 13 subjective cognitive decline (SCD), 22 AD, 39 MCI, and 35 OD. Quantitative analysis of 16 region-of-interests made by Cortex ID software (GE Healthcare). Results: The global mean 18F-Flutemetamol SUVR in SCD, MCI, AD, and OD were 0.50 (SD-0.08), 0.53 (SD-0.16), 0.76 (SD-0.10), and 0.56 (SD-0.16), respectively, with SUVR in SCD and MCI and OD being significantly lower than AD. Aβ binding in SCD, MCI, and OD was heterogeneous, being 23%, 38.5%, and 42.9% respectively, as compared to 100% amyloid positivity in AD. Using global SUVR, ROC analysis showed AUC of 0.868 and 0.588 in differentiating MCI from AD and MCI from OD respectively. Conclusion: 18F-Flutemetamol SUVR differentiated MCI from AD with high efficacy (high negative predictive value), but much lower efficacy from OD. The major benefit of the test was to differentiate cognitively impaired patients (either SCD, MCI, or OD) without AD-related-amyloid-pathology from AD in the clinical setting, which was under-emphasized in the current guidelines proposed by Amyloid Imaging Task Force.

Diagnosis Of Dementia

AbstractObjective: Dementia is a progressive brain disease. The prevalence of dementia increases with age. Symptomatic pharmacological treatments for dementia are available. Psychological and social interventions can support the patient and their carer. Early recognition and diagnosis of dementia are necessary to access this care and reduce crisis-led intervention. A memory clinic service is ideally placed to commence the assessment and management of dementia. The objective of this paper was to describe the setting up of the memory clinic in Cork University Hospital and review the characteristics of the first 118 patients.Method: One hundred and eighteen patients were assessed at the memory clinic between July 2004 and Feb 2007. In general the service operated on a two-appointment system. The first appointment was for a comprehensive assessment with investigations. The second appointment was a feedback session with discussion of the diagnosis, prognosis and management plan for the patient and generally their carer. We examined their demographic characteristics, clinical details, psychological test results and results of investigations.Results: Of the 127 patients referred, 118 (92.9%) attended. Fifteen (12.7%) patients had diagnosis of mild cognitive impairment (MCI), 93 (78.8%) patients were diagnosed with dementia and 5 (4.2%) had diagnosis of depressive disorder with no co-morbid dementia. The dementia type in descending frequency was Alzheimer's disease (50.5%), vascular dementia (34.4%), mixed type dementia (10.8%), Frontal lobe dementia (2.2%) and Lewy body type (2.2%). Of the 93 (78.8%) patients with dementia, 47 (50.5%) had MMSE score ≥20, 29 (31.2%) had MMSE score 11-19 and 17 (18.3%) had score of 0-10. Thirty-three (35.5%) patients were on antidementia medication at the point of referral and a further 16 (17.2%) patients were commenced on these drugs following assessment.Conclusion: The memory clinic provides a service for the assessment of mild cognitive impairment (MCI) and dementia. It offers diagnosis, an opportunity to receive specific advice regarding dementia management, differentiation between dementia and depression and a resource point for carers and patients.

Research Criteria

Background. We explored the applicability of recently proposed research criteria for mild cognitive impairment (MCI) in a memory clinic and changes in case definition related to which memory tests are used and the status of general cognitive function in MCI.Method. A total of 166 consecutive GP referrals to the Cambridge Memory Clinic underwent comprehensive neuropsychological and psychiatric evaluation.Results. Of 166 cases, 42 were excluded (significant depression 8, established dementia 29 and other disorders 5). Of 124 non-demented, non-depressed patients, 72 fulfilled Petersen's criteria for amnestic MCI based upon verbal memory performance [the Rey Auditory Verbal Learning Test (RAVLT)] and 90 met criteria if performance on verbal and/or non-verbal memory tests [the Rey figure recall or the Paired Associates Learning test (PAL)] was considered. Of the 90 broadly defined MCI cases, only 25 had pure amnesia: other subtle semantic and/or attention deficits were typically present. A further 12 were classed as non-amnestic MCI and 22 as ‘worried well’.Conclusions. Definition of MCI varies considerably dependent upon the tests used for case definition. The majority have other cognitive deficits despite normal performance on the Mini-mental State Examination (MMSE) and intact activities of daily living (ADL) and fit within multi-domain MCI. Pure amnesic MCI is rare.

AbstractA group of 94 nondemented patients self-referred to an outpatient memory clinic for memory difficulties were studied to determine the incidence of single versus multi-domain mild cognitive impairment (MCI) using Petersen criteria. Fifty-five community dwelling normal controls (NC) participants without memory complaints also were recruited. Tests assessing executive control, naming/lexical retrieval, and declarative memory were administered. Thirty-four patients exhibited single-domain MCI, 43 patients presented with multi-domain MCI. When the entire MCI sample (n = 77) was subjected to a cluster analysis, 14 patients were classified with amnesic MCI, 21 patients with dysexecutive MCI, and 42 patients were classified into a mixed/multi-domain MCI group involving low scores on tests of letter fluency, “animal” fluency, and delayed recognition discriminability. Analyses comparing the three cluster-derived MCI groups versus a NC group confirmed the presence of memory and dysexecutive impairment for the amnesic and dysexecutive MCI groups. The mixed MCI group produced lower scores on tests of letter fluency compared with the amnesic MCI and NC groups and lower scores on tests of naming and memory compared with the NC group. In summary, multi-domain MCI is quite common. These data suggest that MCI is a highly nuanced and complex clinical entity. (JINS, 2010, 16, 84–93.)
