Health After eaRly Menopause Due to Oophorectomy
Surgical MenopauseBRCA1 Mutation6 moreRisk-Reducing Salpingo-Oophorectomy (RRSO) at the age of 35 to 45 years is recommended for women with a high genetic risk for ovarian cancer. While this procedure decreases the risk of ovarian cancer by 80-96%, it also results in an immediate menopause. Current research on potential adverse effects of premenopausal risk-reducing salpingo-oophorectomy, such as increased risk of cardiovascular disease, compromised bone health, cognitive dysfunction and reduced quality of life, is limited, mostly due to short follow up. The investigators will conduct a multicenter cross-sectional study nested in a cohort of BRCA mutation carriers from 8 Dutch centers for hereditary cancer. Eligible participants are women who underwent RRSO before the age of 45. The participants will be frequency-matched on current age with women above the age of 55 without RRSO or with RRSO after the age of 55. Participants will complete an online questionnaire containing various questions about lifestyle, medical history, risk factors for cardiovascular disease, bone health, cognition and quality of life. Participants will be asked to visit one of the participating hospitals for a blood test, a cardiovascular assessment and a DEXA scan for determining bone mineral density. Afterwards participants will be requested to perform the online Amsterdam Cognition Scale.

A Retrospective Analysis of Cerefolin NAC® in Cognitively Impaired Patients
Mild Cognitive ImpairmentThis retrospective analysis of de-identified data from 700 charts of consecutive patients from this patient population is to investigate the prevalence of hyperhomocysteinemia and associated metabolic abnormalities in this naturalistic grouping of patients with various stages of cognitive loss and diagnosed with various types of dementia.
The Long-Term Safety and Efficacy Follow-Up Study of Subjects Who Completed the Phase I Clinical...
Alzheimer DiseaseDementia10 moreThe purpose of the study is to determine the long-term safety and exploratory efficacy of NEUROSTEM®-AD, administered via an open brain surgery to subjects with dementia of the Alzheimer's type, who were eligible for and enrolled in the earlier part of the phase I. Aside from the subjects who completed the earlier part of the Phase I, 3 additional subjects with comparable demographics and disease characteristics as the treatment group will be enrolled into a control group, followed-up for 3 months, and compared for various disease progression indicators with the treatment group. The hypothesis is that NEUROSTEM®-AD is safe and effective in the treatment of dementia of the Alzheimer's type.
Psychopathological Risk Factors Associated With Conversion From Mild Cognitive Impairment to Dementia...
Mild Cognitive ImpairmentBackground: Dementias (Alzheimer's disease and related syndromes), in their sporadic form, have multifactorial origin. Several risk factors (RF) are currently recognized like the cardiovascular RF, some genes of susceptibility, but the impact [1] of traumatic life events (TLE), considered as psychosocial RF (Persson & Skoog, 1996; Charles et al, 2006), [2] of anxiety and/or depression, [3] of the premorbid personality (Clément et al, 2003) with his coping strategies, and [4] of the lifestyle (which results from the personality), for the moment are still underestimated. Dementia disease can be clinically preceded by a mild cognitive impairment (MCI) (Petersen et al, 1996) which is however potentially reversible. Purpose: Actually, there is no study concerning the rate of conversion from MCI to dementia according to the presence or not of TLE. The aim of this study is to assess association between TLE and conversion rate from MCI to dementia. Methods: Patients with MCI will be recruited in different memory clinics (Limoges and others) Primary outcome: Occurrence of dementia according to DSM-IV-TR criteria in MCI patients according to their cumulated score of TLE measured by EVVIE. Secondary outcomes: Occurrence of dementia in MCI patients according to various other psychopathological factors: anxiety, depression, apathy, personality features, alexithymia and resilience levels and life style. Study design: Epidemiologic cohort longitudinal and prospective multicenter study.
Korea Alzheimer's Disease Neuroimaging Initiative
Mild Cognitive ImpairmentAlzheimer's Disease1 morePRIMARY OBJECTIVES -Establish a registry for Alzheimer's disease (AD) and subcortical ischemic vascular dementia (SIVD) STUDY DESIGN -This is a non-randomized, natural history, observational, registry study. SAMPLE SIZE AND RECRUITMENT - Five hundred subjects will be enrolled at each clinical site (50 NC, 200 with MCI, 50 with AD, 100 with vMCI, and 100 with SIVD) SUMMARY OF KEY ELIGIBILITY CRITERIA Newly enrolled subjects will be between 50-80 (inclusive) years of age. 1) Cognitively Normal Subjects 2) MCI subjects 3) AD subjects 4) vMCI or SIVD PROCEDURES Recruited subjects will have clinical/cognitive assessments, biomarker and genetic sample collection, and imaging. Subjects will be followed up for 36 months from the baseline visit. All assessments are to be performed every year from baseline(0, 12, 24, 36 months), except; 1) FDG-PET and amyloid-PET will be performed every two years, i.e., on baseline and at 24 month visit. 2) CSF collection will also be performed on baseline and at 24 months visit. 3) Clinical/cognitive assessment and MRI evaluation will additionally be done at 6 months from baseline to determine short term change. OUTCOME MEASURES Group differences for each clinical, cognitive, biochemical, and imaging measurement. Rate of conversion or change of disease severity will be evaluated among all groups Correlations among biomarkers and biomarker changes

Evidence Amyloid Scan EEG Study
Alzheimer DiseaseDementia Frontal1 moreThe Evidence Amyloid Study EEG (EASE) establishes an open-label, longitudinal cohort study to measure of neurological functioning during the onset and progression of cognitive decline in preclinical Alzheimer's patients using quantitative electroencephalography (qEEG) measures (P300, P50, and reaction time). Participants will be scanned using the ElectroCap (FDA Class II) and/or the WAVi headset with the WAVi EEG P300/P50 system, along with the structured clinical interviews and assessments for baseline screening or mild cognitive impairment which are standard of care.
