BioFINDER 1 is used e.g. to characterize the role of beta-amyloid pathology in early diagnosis of Alzheimer's disease (AD) using amyloid-PET (18F-Flutemetamol) and Aβ analysis in cerebrospinal fluid samples. The BioFINDER 1 study has resulted in more than 40 publications during the last three years, many in high impact journals, and some the of the results have already had important implications for the diagnostic work-up patients with AD in the clinical routine practice.\n\nThe original BioFINDER 1 cohort started to include participants in 2008. Since then there has been a rapid development of biochemical and neuroimaging technologies which enable novel ways to the study biological processes involved in Alzheimer's disease in living people. There has also been a growing interest in the earliest stages of AD and other neurodegenerative diseases. With the advent of new tau-PET tracers there is now an opportunity to elucidate the role of tau pathology in the pathogenesis of AD and other tauopathies. The Swedish BioFINDER 2 study has been designed to complement the BioFINDER 1 study and to e.g. address issues regarding the role of tau pathology in different dementias and in preclinical stages of different dementia diseases. Further, the clinical assessments and MRI methods have been further optimized compared to BioFINDER 1. Detailed assessments of motor aspects and dual task performance, which is part of a sub-study named Motor-ACT: \"Motor aspects and activities in relation to cognitive decline and brain pathologies, has been added to further optimize assessment of motor function.",[28,29,30,31,32,33,34,35,36,37,38,39,40],"Dementia","Alzheimer Disease","Parkinson Disease","Lewy Body Disease","Parkinson-Dementia Syndrome","Frontotemporal Degeneration","Semantic Dementia","Progressive Nonfluent Aphasia","Progressive Supranuclear Palsy","Corticobasal Degeneration","Multiple System Atrophy","Mild Cognitive Impairment","ALS (Amyotrophic Lateral Sclerosis)",[42],"Early diagnosis, biomarker, PET, MRI, β-amyloid, tau, CSF, cognitive test","RECRUITING","2026-04-01",{"date":46,"type":47},"2026-04-06","ACTUAL",{"date":49,"type":47},"2017-05-15",{"date":51,"type":22},"2036-12",{"name":53,"class":54},"Skane University Hospital","OTHER",{"id":56,"slug":57,"hasResults":11,"nctId":58,"briefTitle":59,"officialTitle":60,"acronym":4,"eligibilityCriteria":61,"healthyVolunteers":16,"sex":17,"minAge":62,"maxAge":63,"enrollmentInfo":64,"targetDuration":4,"studyType":66,"phases":4,"briefSummary":67,"conditions":68,"keywords":4,"overallStatus":43,"whyStopped":4,"lastUpdateSubmitDate":72,"lastUpdatePostDateStruct":73,"startDateStruct":75,"completionDateStruct":77,"leadSponsor":79,"locationsCount":81},"100283059","diagnosing-frontotemporal-lobar-degeneration-100283059","NCT02964637","Diagnosing Frontotemporal Lobar Degeneration","Multimodal Assessment for Predicting Specific Pathological Substrate in Frontotemporal Lobar Degeneration","Inclusion Criteria:\n\n* Participant must have a reliable study partner who can provide an independent evaluation of functioning.\n* Able to read, understand and speak English for neuropsychological testing.\n* All subjects must meet one of these diagnostic criteria (A) probable behavioral variant FTD, (B) MRI-supported non-fluent variant PPA; (C) MRI-supported semantic variant PPA and \\[18F\\]T807 negative (D) probable CBS: using current criteria for CBS(27); (E) PSP: inclusion criteria for PSP are based upon the National Institute of Neurological Disorders and Stroke Society of Progressive Supranuclear Palsy (NINDS-SPSP) (F) FTD-MND\n* Control subjects must have a normal neurological exam, a CDR sum of boxes = 0, and MMSE score equal to or greater than 28\n\nExclusion Criteria:\n\n* Patients with clinical, imaging or CSF A beta\u002F tau profile consistent with AD\n* History of traumatic brain injury, brain tumors, stroke or other neurological or psychiatric disorders that can explain symptoms will be excluded.\n* Premenopausal women will be asked to consent to a pregnancy test prior to each scan as pregnant women will be excluded from study because of potential harm to fetus from PET study.\n* Presence of pacemakers, aneurysm clips, artificial heart valves, ear implants, metal fragments or foreign objects in the eyes, skin or body.","18 Years","90 Years",{"count":65,"type":22},100,"OBSERVATIONAL","To establish diagnostic tools to make an accurate clinical and pathological diagnosis of patients with clinical FTLD syndromes",[69,36,70,34,35,71],"Corticobasal Syndrome","Behavioral Variant Frontotemporal Dementia","Amyotrophic Lateral Sclerosis And\u002For Frontotemporal Dementia","2025-03-25",{"date":74,"type":47},"2025-03-30",{"date":76,"type":4},"2015-08",{"date":78,"type":22},"2026-12",{"name":80,"class":54},"University Health Network, Toronto",1]
