MEMORA-Caregiver : Risk Factors of Caregiver Burden Among Patients With Neurocognitive Disorders...
Neurocognitive DisordersThe investigators will investigate which patients' characteristics are associated with caregivers burden and its evolution for outpatients visiting a memory clinic, in particular how functional autonomy, behavioral and psychological symptoms as well as patients comorbidities can influence caregiver burden. The study will be conducted among outpatients with progressive cognitive complaint followed in a Memory Clinic and their primary caregiver. The investigators hypothesis that caregivers experience a higher burden due to disease symptoms such as impairment of functional autonomy, behavioral and cognitive impairment, whatever the aetiology of the cognitive decline.
Neuropsychological Indicators of SCD Progression
BiomarkersCognitive Assessment4 moreSome patients with subjective cognitive decline (SCD) progress to neurocognitive disorders (NCD), whereas others remain stable; however, the neuropsychological determinants of this progression have not been identified. The investigators objective was to examine baseline neuropsychological indicators that could discriminate between people in whom the SCD progressed to a mild or major NCD and people in whom the SCD remained stable. The investigators retrospectively included patients consulting for SCD at a university medical center's memory center (Amiens, France) and who had undergone three or more neuropsychological assessments at least 6 months apart. The relationship between domain-specific scores and the global cognitive score (GCS, as a function of final status (stable SCD vs. progression toward a mild or major NCD)) was examined using a generalized linear mixed model.
An Individualized Exergame Training Solution for People With Major Neurocognitive Disorder: a Usability...
Major Neurocognitive DisorderPhysical Activity1 moreThe aim of this study is to investigate the usability of a newly designed and developed user-centered exergame in older adults with major neurocognitive disorder (dementia).
The Prevalence of Neurocognitive Disorder in a Primary Care-based HIV Cohort Compared to a HIV-negative...
HIV-1-Associated Cognitive Motor ComplexTo determine the prevalence of HIV associated Neurological Disorder (HAND) in a population of HIV positive patients within a primary care setting compared with the HIV negative population. The investigators aim is to assess the use of optimal screening methods to assess HAND. For this the investigators will be comparing the performance of a group of persons who are HIV positive and a group of persons who are HIV negative to test their memory and concentration abilities over-time.
Observational Study of HIV-associated Neurocognitive Disorder
HIV Associated Neurocognitive DisorderHuman Immunodeficiency VirusIt is estimated that over 1 million people in the United States have HIV infection. While HIV is treatable, there are still high rates of HIV-associated neurocognitive disorder (HAND). HAND is defined by low scores on memory testing. To meet the criteria for HAND, an HIV-infected individual has to have a low score on at least two different memory tests. It is estimated that 20-50% of people living with HIV have HAND. It is therefore still a common problem. While individuals with HAND typically improve on antiretroviral therapy for HIV, often this improvement is incomplete. Also, there are over 20 antiretroviral medications approved for HIV in the US. It is not clear if the specific choice of antiretroviral medication makes a difference in the improvement of HAND. The investigators have designed a small preliminary study in which subjects with and without HAND who have never been on treatment for HIV or have been off treatment for at least 6 months are followed for the first 12 months after starting antiretroviral therapy.The investigators will enroll a maximum of 46 subjects (23 subjects in each arm). Subjects will also be followed by their primary HIV medical provider. For the study, subjects will be followed for 48 weeks. There are three followup visits: 12 weeks, 24 weeks, and 48 weeks. Memory testing will be performed at baseline and each followup visit. Blood will also be taken at baseline and the three followup visits to measure changes in inflammation. A lumbar puncture will be performed at baseline and at 24 weeks to measure changes in inflammation and amount of HIV virus in the spinal fluid. There is also an optional lumbar puncture at the last study visit of 48 weeks
Preoperative Cognitive Impairment Predicts Postoperative Delirium
Delirium in Old AgeNeurocognitive Disorders1 morePreoperative cognitive impairment (PCI) may increase the incidence of postoperative delirium (POD), yet screening for cognitive impairment is rarely performed. This study hypothesized that Mini-Cog for preoperative cognitive impairment screening predicts postoperative delirium. Elderly patients (65 years or older) attending Henan Provincial People's Hospital during the trial period who required elective thoracic surgery were recruited into the study.

Interest of Functional Neuroimaging in Assessing Decision-making Capacity of Older People With Neurocognitive...
Decision MakingDementia1 moreIMAGISION aims to explore, in a cohort of patients referred for geriatric consultation for neurocognitive evaluation, the contribution of functional neuroimaging (functional MRI and, if possible, high resolution EEG) to geriatric expertise, associated with the performance of a battery of neuropsychological tests in the evaluation of decision-making capacity.
Evaluation of Cognitive Impairment in the Elderly Admitted to Nursing Homes
Neurocognitive DisorderEtiology of Neurocognitive DisorderThis research aims at analysing the profile of the elderly with cognitive impairment (IC) and inquiring about the mental illnesses that cause cognitive impairment of a population (elderly admitted to nursing homes with a high incidence).
Comparison Study of the Different Abbreviated Versions of the Geriatric Depression Scale
DepressionDepressive Disorder2 moreThis multicenter study conducted in several Portuguese institutions aims to compare the screening ability of the several Geriatric Depression Scale (GDS) validated versions for the Portuguese population (GDS-30, GDS-15, GDS-10 and GDS-5), as well as to establish their psychometric properties, using a large sample of elderly people with neurocognitive disorders attending social responses addressed to the elderly. Secondarily, cognitive state will be assessed.
