Filter by:Within this project the investigators tested the effectiveness of 2-month of computerized cognitive training (CCT) on CogniFit online platform on 77 older adults, which were randomly divided into intervention and control group. The investigators tested close (battery of cognitive functions) and far transfer (postural and mobility control, EEG, blood samples) of the CCT. Additionally, the investigators were interested into seeing a long-lasting effect, therefore participants were brought back to the laboratory 1 year post CCT.
Background: 36% of the Italian population will have more than 65 years in 2050. The European Union has indicated among its priorities to increase research on active aging. Physical activity contrasts disability linked to chronic diseases, has positive effects on the quality of life and on biological rhythms, prevents the decline of motor functions, improves the immune response, and prevents / positively affects metabolic disorders. It also provides valuable support in coping with cognitive decline and memory, and acts on depressive symptomatology. The literature on active aging is based, to date, on studies with small samples, rarely conducted with a randomized controlled method, whose outcomes often appear contradictory. The multidisciplinary project the investigators propose is an opportunity to address the issues mentioned above and to acquire further knowledge in the field of active aging. Objectives: the main objective of the study is to evaluate the effects of mild-to-moderate physical activity in a sample of over-65 years-old persons, on Quality of Life, and on biomechanical parameters (static-dynamic balance, mobility). The secondary objectives are aimed at assessing whether a protocol of mild-to-moderate physical activity can improve: - Metabolic functions - Cognitive performance - Perception of pain - Social rhythms and psychological wellbeing - Inflammatory state Design: randomized controlled trial (RCT), single-blinded, with follow-up. Sample: participants will be ≥ 65 years old, of both genders, sedentary, enrolled in two arms through a random assignment (treatment/control) with ratio of 1:1, as following: - about 60 subjects who will carry out a light-to-moderate physical activity intervention (experimental group); - about 60 subjects in the control group, who will participate in group cultural activities (active comparison group). Assessment: the assessment will include socio-demographic variables; variables of psychophysical wellbeing; cognitive variables; variables related to physical health; biomechanical variables; assessment of skin integrity; lab tests on blood samples. Times of evaluations: both groups will be subjected to the measurements of the present study according to the following schedule: - T0 (baseline): before the start of the intervention - T1: 12 weeks after T0 (at the end of the intervention) - T2: after 20 weeks from T0 (follow up 1) - T3: 48 weeks after T0 (follow-up 2).
The research team is creating a foundational infrastructure in order to develop a precision medicine approach for geriatric patients who require surgery with anesthesia. The team plans to build the first of its kind comprehensive database of demographic and risk factor questionnaire responses, biobanked blood specimens, intraoperative electroencephalography (EEG), and inclusive cognitive testing throughout patient interaction starting at the preop appointment until a year later. This will be used to create a predictive model of periooperative neurocognitive disorders.
Risk-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.
We use Transcranial magnetic stimulation (TMS), combined with simultaneous registration of electroencephalograph (EEG),for examining human cortical functionality. TMS-EEG is a noninvasive brain stimulation method that allows to study human cortical function in vivo. EEG provides an opportunity to directly measure the cerebral response to TMS, measuring the cortical TMS Evoked potential (TEP). In this study we measure TEPs, in a wide variety of neurological conditions and healthy as a measure of cerebral reactivity across wide areas of neocortex.
To assess the effect of glucose monitors on glucose control and cardiovascular risks.
Hip fracture is a potentially devastating event, and serious surgical and medical complications occur frequently especially for elderly patients. Delirium is one of the common complications after hip surgery. Controversy exists regarding the possible impact of type of anesthesia (nerve block versus spinal) upon acute and long-term cognitive decline. The primary objective is to assess the association between type of anesthesia (nerve block vs. spinal anesthesia) and risk of cognitive decline (CD). The secondary objective is to compare intra-operative hemodynamic changes, use of vasopressor drugs, and use of post-operative analgesics with respect to the type of anesthesia. Prospective, double blind randomized clinical trial of hip fracture patients who will be assessed for CD pre- and postoperatively, using the Mini Mental State Examination (MMSE). The presence of CD will be determined at follow-up evaluation up to three months after surgery.
Certain clinical syndromes eg frailty, sarcopenia, dementia, depression, cognitive impairment, vision impairment and falls in older adults carry an increased risk for poor health outcomes and if identified early, can be prevented, delayed or reversible. There is evidence to suggest that exercise and dietary intervention can help delay or prevent sarcopenia, frailty and dementia. The current hypothesis is older adults do not consume enough protein in their diet. Local delicacies enhanced with protein content, in addition to physical activity will improve muscle strength, function, perceived health status and possibly may even reverse frailty and sarcopenia. Additionally, it is hypothesized that combination of multi component group exercise activities and high protein nutrition will be effective in improving participants' social, mental and physical status.
A Sub-Study of an investigator initiated and conducted, multicentre, international, double-blinded, placebo-controlled, parallel-group, randomised controlled trial (TRIDENT) to determine the effect of more intensive long-term blood pressure control, provided by a fixed low-dose combination blood pressure lowering pill ("Triple Pill") strategy on top of standard of care, for slowing memory decline as measured by Cambridge Neuropsychological Test Automated Battery (CANTAB), in patients with a history of acute stroke due to intracerebral haemorrhage (ICH).
Cardiorespiratory fitness (CRF) is associated with decreased risk for mild cognitive impairment (MCI) and dementia. CRF is linked with more conserved gray and white matter (WM) volume, improved WM microstructural integrity, and better cognitive performance among healthy older adults. Additional research is needed to determine: (1) which WM tracts are most strongly related to CRF, (2) whether CRF-related benefits on WM translate to enhanced cognitive functioning, and (3) factors that mediate and moderate CRF effects. Higher CRF was hypothesized to be associated with stronger WM integrity, both globally and locally in WM tracts that connect frontal brain regions. The neuroprotective effects were hypothesized to be age-dependent, such that the association between CRF and WM integrity would be stronger in old age compared to younger age. Finally, higher CRF was hypothesized to predict stronger performance on tests of executive functioning (EF), partially mediated by frontal WM integrity. Delineation of specific neurocognitive effects of CRF may serve clinicians in individually tailoring wellness interventions to meet patients' specific cognitive concerns with aging.
