[18F]AV-45 was studied in a total of 16 HC volunteers and 16 AD patients. Patients with AD had to be greater than 50 years of age and have a probable diagnosis of AD according to the NINCDS-ADRDA, with a Mini-Mental State Examination (MMSE) score between 10 and 24 inclusive. (12 (link), 13 (link)) HC subjects had to be greater than 50 years of age, with no evidence of cognitive impairment by history and psychometric testing, and had to have an MMSE score of ≥ 29. Subjects who showed evidence of any other significant neurodegenerative or psychiatric disease on clinical examination or MRI, or clinically significant medical comorbidities that might pose a safety risk to the subject or interfere with interpretation of the scan were excluded from the study. Patients with AD could be on a stable dose (by investigator judgment: not in titration period, no change in medication being considered) of an acetylcholinesterase inhibitor, memantine, and/or Vitamin E. Patients who had ever participated in an experimental study with a treatment targeting amyloid (e.g., immunotherapy, secretase inhibitor, selective amyloid lowering agents) were excluded. All procedures were approved by the appropriate Institutional Review Board and all participants or an appropriate representative signed informed consent forms, consistent with established criteria (12 (link)).
Similar acquisition protocols were used at the three centers. All subjects received a single IV bolus of approximately 370 MBq or 10 mCi [18F]AV-45 and PET imaging began. Dynamic brain PET images were collected for a period of approximately 90 minutes. The PET scanners employed were GE Advance (PET only, at JHU), GE Discovery LS (PET/CT), at CHC and MEC, and the Discovery ST (PET/CT), at MEC). In addition plasma metabolite analysis was conducted using the method of Hilton, et al (14 (link)). For detailed PET, metabolite analysis and image acquisition procedures see supplementary information.

Clinical dementia diagnoses were defined as confirmed diagnoses of dementia recorded by clinicians following clinical assessment. All memory assessments were then summarised in anonymised case vignettes by the researchers, without making reference to clinical diagnosis. We also removed reference to treatment with acetylcholinesterase inhibitors and memantine. Case vignettes were also produced for assessments preceding and following the diagnosis of dementia, where available.
The case vignettes were then presented to two raters who worked independently to rate the case by applying diagnostic criteria delineated in ICD-10 and DSM-IV-TR; that is, the raters assigned the case to ‘no dementia’ or ‘dementia’ according to either ICD-10 or DSM-IV-TR criteria (Table 1). Use of the ICD-10 category of ‘tentative dementia’ was also included.
Raters were also asked to make a separate rating based on their clinical judgement and rate the cases as no dementia, ‘cognitive concern’, ‘possible dementia’ or ‘certain dementia’. Cognitive concern was defined as any evidence of deterioration in cognitive function but where this was of recent onset only and where the rater was unable to exclude a physical causation (such as hypothyroidism) or a mental illness causing changes in behaviour or memory (such as depression). Possible dementia was defined as likely dementia (i.e. significant decline over 6 months or more) but where the raters felt the vignette lacked evidence to be certain of a diagnosis and where they would have wanted further information or to offer another appointment to confirm results and symptoms.
Raters were clinicians (psychiatrists and psychologists) working in the fields of Psychiatry of Intellectual Disability or Psychiatry of Older People who were members of a ‘dementia in intellectual disabilities’ special interest group. Raters remained blinded to the patient’s true clinical diagnosis and any treatment received.
After rating each assessment independently, the raters compared outcomes for each assessment. Where there was disagreement between the raters’ outcomes, a discussion ensued, and a consensus was achieved and recorded. For a subset of assessments, the outcome of each individual rater was recorded prior to consensus allowing for determination of inter-rater reliability.

The Finnish special reimbursement register contains information on reimbursement due to specific chronic diseases such as diabetes, cardiovascular diseases, and Alzheimer’s disease. As per national guidelines for Ad treatment,15 (link) this register allows identification of every person with clinically diagnosed Ad, regardless of whether they purchased the Ad medication after being diagnosed. We are not aware of this kind of nationwide register with longitudinal data elsewhere, although Sweden recently set up the Swedish dementia Registry (SveDem), including 6,937 dementia patients diagnosed during 2007–2009.14 (link)
The Finnish Current Care Guidelines recommend that all persons with Ad are treated with acetylcholinesterase inhibitors or with memantine unless there is a specific contraindication.15 (link) To be eligible for reimbursed Ad medication, the patient needs to have a verified diagnosis of Ad described in a medical statement submitted to the SII by a physician. The medical statement must state that the patient has: (1) symptoms consistent with Ad; (2) experienced a decrease in social capacity over a period of at least 3 months; (3) received a computed tomography/magnetic resonance imaging scan; (4) had possible alternative diagnoses excluded; and (5) received confirmation of the diagnosis by a registered neurologist or geriatrician.15 (link) Ad is diagnosed according to the National Institute of Neurological and Communicative disorders and Stroke and the Alzheimer’s disease and Related disorders Association (NINCDS-ADRDA [now known as the Alzheimer’s Association]) and The Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria for Alzheimer’s disease.16 (link),17 The physician also needs to confirm whether the patient has other dementing diseases, such as multi-infarct dementia or Lewy body dementia. However, patients with these diseases are also entitled to reimbursed medicines if the symptoms are considered to be mainly caused by AD.18
The special reimbursements for acetylcholinesterase inhibitors and memantine were introduced in 1999 and 2003, respectively, and the diagnostic criteria have been consistent. In the beginning, the reimbursement decisions were often made on a temporary basis, but permanent decisions were introduced in July 2003. earlier, only patients with mild or moderate Ad were entitled to reimbursed anti-dementia medication, but the reimbursement was not withdrawn if/when the patient developed severe ADs. People with severe Ad have been entitled to reimbursed AD medication since 2003. Thus, our study sample includes persons with all stages of AD. data on severity or stage of Alzheimer’s disease is not available from the registers, but the diagnosis date from the special reimbursement register can be used as a crude estimate on mild/moderate stages of AD. The Finnish public health system covers all residents regardless of age or income. Thus, one of the strengths of our cohort is that, unlike cohorts consisting of members of a particular private health care insurance scheme, MedAlz-2005 is not selected on the basis of socioeconomic position.

The Modified Mini-Mental State Examination (3MSE)21 (link) was administered at every 6-month visit, as was the cognitive subscale of the Alzheimer Disease Assessment Scale (ADAS-Cog)22 (link) through August 1, 2004; thereafter, the ADAS-Cog was administered annually in alternation with the all-study annual neuropsychological evaluations, as described below. The Telephone Interview for Cognitive Status23 was administered when in-person visits were missed.
A comprehensive neuropsychological test battery was administered to all participants at study screening and at annual intervals beginning in 2004 (approximately 3-4 years after randomization). In addition to these regularly administered (all-study) neuropsychological evaluations to all participants, diagnostic neuropsychological evaluations (consisting of the same neuropsychological tests) were administered to participants with potential cognitive changes as part of the mechanism for diagnosing dementia, the primary GEM study outcome. Diagnostic neuropsychological evaluations were administered at any visit during the study for the following reasons: (1) specified point decline on 2 of the 3 cognitive screening tests (3MSE, CDR, or ADAS-Cog); (2) onset of a new memory or other cognitive problem reported by the participant or family; (3) new dementia diagnosis by a nonstudy physician; or (4) initiation of a medication with a cognitive indication, such as donepezil, rivastigmine, galantamine, or memantine.
The neuropsychological test battery was designed to assess multiple cognitive domains and be maximally sensitive to detecting cognitive decline associated with preclinical or incident dementia. Memory tests included the California Verbal Learning Test24 and recall conditions of the modified Rey Osterrieth Figure Test.25 (link) Tests of visual-spatial construction included the copy condition of the Rey Osterrieth Figure Test and the modified Wechsler Adult Intelligence Scale–Revised (WAIS-R) Block Design.26 (link) Language tests included a 30-item Boston Naming Test27 (link) and semantic verbal fluency.28 Tests of attention and psychomotor speed included the WAIS-R Digit Span and the Trail Making Test Part A.29 Tests of executive functions included the Trail Making Test Part B29 and Stroop Color/Word Test.30

The primary outcome of this study was the incidence of all-cause dementia, including Alzheimer’s disease (AD), vascular dementia (VaD), and other types of dementia (ICD-10 diagnostic codes: F00, F01, F02, F03, G30, or G31). Outcome events were defined when both ICD-10 codes and the prescription records of anti-dementia drugs, including donepezil, galantamine, rivastigmine, and memantine were used. This definition has been widely accepted with high accuracy, having 94.7% positive predictive value in K-NHID21 (link). The secondary outcomes included AD (F00 or G30) and VaD (F01). The date of the second health checkup was defined as the index date, and the participants were followed up until December 31, 2019 or until the development of the primary outcome, whichever came first.
We obtained information from the second general health checkup based on previous studies related to risk factors for dementia. Specifically, we obtained demographic data, including age, sex, height, body weight, and waist circumference, as well as information regarding health-related lifestyles, including smoking status, categorized as a current smoker or not, and alcohol consumption status, categorized as alcohol users (any alcohol consumption) or not. Baseline comorbidities including hypertension, dyslipidemia, diabetes mellitus, and chronic kidney disease were also obtained. The operational definition of covariates and outcomes in cardiovascular research is well documented in several studies based on K-NHID12 (link). CKD was defined as an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73 m2 calculated using the CKD Epidemiology Collaboration (CKD-EPI) equation. Low-income level was defined when the participants were medical benefit beneficiaries and were included in the lowest quartile of income levels. Further, laboratory data, including levels of random glucose, total cholesterol, glomerular filtration rate, and systolic/diastolic blood pressure, were also obtained at the ambulatory health exam visits after index stroke. Among these variables, age, sex, smoking status, alcohol consumption, income level, history of diabetes mellitus, hypertension, dyslipidemia, and chronic kidney disease were used as covariates.

Chi-square for categorical variables and Mann–Whitney U test for continuous variables due to non-normality were used to compare the baseline characteristics between patients with RLS and RLS-free controls. Cox proportional hazards regression models were applied to explore the association between RLS and the risk of dementia after adjusting for age, sex, income, residence, CCI, and history of other comorbidities. Among the Cox regression models, we used the Fine–Gray subdistribution hazard model with mortality as a competing risk given the old age of the study population. The proportional hazard assumption was satisfied in our Cox model (Schoenfeld individual test p-value > 0.05).
Sensitivity analyses were performed using four different models. In model 1, dementia was defined as the prescription of anti-dementia medications (donepezil, rivastigmine, galantamine, and memantine) at least twice and a diagnosis of the ICD-code of dementia. Although these medications were approved for only AD (rivastigmine additionally for Parkinson’s disease dementia), they can be used for cognitive symptoms in other types of dementia based on recommendations from multiple guidelines [31 (link)–33 (link)]. The previous study revealed that the definition of all-cause dementia by ICD-10 code plus anti-dementia medications had a positive predictive value of 94.7% when reviewing the medical records of 972 patients in two hospitals [34 (link)]. In model 2, medication history was added to the ICD code to define RLS. Patients with RLS ICD-code (G25.8) who had taken dopamine agonists (ropinirole or pramipexole) twice or more were regarded as patients with RLS (n = 1458). In this sensitivity model, we excluded patients with Parkinson’s disease because they could also take dopamine agonists. In model 3, patients taking antipsychotic agents were excluded because the antidopaminergic property of antipsychotic agents could lead to a misdiagnosis of RLS (n = 2482). The following antipsychotic agents approved in South Korea were used in this study: haloperidol, sulpiride, chlorpromazine, perphenazine, pimozide, risperidone, olanzapine, quetiapine, paliperidone, amisulpride, aripiprazole, ziprasidone, clozapine, blonanserin, and zotepine. In model 4, patients with RLS only diagnosed by psychiatrists or neurologists were included (n = 1154) to preclude the possible misdiagnosis by non-expert physicians.
To evaluate the effect of dopamine agonists (pramipexole and ropinirole) on the development of dementia, the risk of dementia was compared after dividing RLS patients by dopamine agonist use. Patients with RLS who were prescribed pramipexole or ropinirole at least once were considered dopamine agonist users. All missing data were addressed using listwise deletion. Data processing and statistical analyses were performed using SAS version 9.4 (SAS Institute, Cary, NC, USA). Statistical significance was set at a two-tailed p-value of < 0.05.
