Filter by:Two hallmarks of both healthy aging and age-related disease are 1) memory and navigational deficits, particularly in orienting towards goal locations and planning how to navigate to them, and 2) increased susceptibility to stress and altered regulation of the stress response. However, there are marked individual differences in these age-related changes. The investigators' proposal will help characterize factors that contribute to this variability. Participants will be pseudorandomly assigned to stress-manipulated or control groups. The investigators will give both groups a novel immersive navigation task, validated by the PI in healthy young adults. This paradigm gives participants the opportunity to either (a) flexibly draw on spatial memory in order to plan efficient routes to goal locations, or (b) fall back on inefficient, but cognitively less-demanding, stimulus-response associations (i.e., habits). Using neuroimaging and behavioral measures, the investigators' protocol will test whether experimentally-induced stress leads individuals to bring fewer details about future locations to mind when route planning, and whether such restricted prospective thought ultimately biases participants towards relatively inflexible, habitual actions.
The study aims to use machine learning to predict the occurrence of episodic and autobiographical memory deficits as well as treatment response following a course of electroconvulsive therapy. Additionally, the neurophysiological correlates of the cognitive effects after a course of ECT will be investigated. Therefore, structural, resting-state and diffusion tensor images will be collected within one week before the first and after the last ECT treatment from severely depressed patients. Standard measures of cognitive function and specifically episodic as well as autobiographical memory will also be collected longitudinally and used for prediction. The study consists of 60 ECT receiving inpatients suffering from major unipolar or bipolar depression, 60 medication-only controls and 60 healthy controls.
Despite combined antiretroviral therapy (cART), milder forms of HIV-associated neurocognitive disorders (HAND) persist in 20-50% of persons living with HIV (PLHIV). Since more PLH are at risk for HAND due to aging, the frequency of HAND in PLHIV ≥ 65 years old is important to quantify for planning early intervention to attenuate both functional and occupational disabilities due to cognitive impairment.
Objective: There have been a wide variety of interventions to assist with cognition and memory of older adults; however, it is often unclear if the interventions have an impact on daily life memory performance and goal attainment. The objectives of this study are to examine: 1) whether an intervention that involves a simple memory tool assists with daily life memory performance and goal attainment of older adults; and 2) whether the intervention has a different effect for individuals with healthy cognition versus individuals with mild cognitive impairment (MCI). Research Questions: Can a simple memory tool assist with daily life memory performance and goal attainment for older adults? Does the simple memory tool have a different effect for individuals with healthy cognition and individuals with MCI? Methods: The study will use a mixed 2 X 3 design with cognition (healthy, MCI) as the between subjects factor and time (session 1, 2, 3) as the within-subjects factor. There will be 40 older adults who have healthy cognition and 20 older adults who have MCI. The study will consist of 3 sessions for each participant. The sessions will be held once a week and incorporate: a) the Montreal Cognitive Assessment (MOCA) to determine level of cognition (healthy, MCI); b) the Prospective and Retrospective Memory Questionnaire (PRMQ) to help determine daily memory performance; c) a memory recall test for recent daily events to help determine daily memory performance; d) the goals of the participants using the Goal Attainment Scaling (GAS); and e) the development of checklists that are tailored to address goals. In between the sessions, participants will perform the checklists and update the diary with notes of what they want to remember on a daily basis. The hypotheses are that: 1) memory performance (i.e., measured with memory recall of daily events and PRMQ), and goal attainment will increase from session to session; 2) participants with healthy cognition will have better memory performance and goal attainment than participants with MCI; and 3) participants with healthy cognition will have greater gains in memory performance and goal attainment than participants with MCI.
The Alzheimer's disease or related disorders (ADRD) are among the most disabling diseases because of their main features such as cognitive impairment, loss of functional autonomy and behavioural disorders. In absence of current curative treatment, the identification of the predictive risk factors of progression of the disease, evaluated through its main symptoms, represents a major stake of public health. The investigators aimed at developing a database, which includes the patient medical records on a prospective basis, in collaboration with the medical and administrative personal and with the University hospital computer science department. The main objective is to study the predictive factors associated with the change of functional autonomy level, measured every 6 months to 12 months by phone, in a Memory Clinic. The study population would consist in about 1000 patients with ADRD. The length of follow-up of each patient will be 3 years.
This study has two purposes: firstly, a better understanding of the neurobiological processes underlying episodic memory and, secondly, the development of useful clinical applications for epileptic patients, in particular the prediction of postoperative memory deficits and the development of cognitive remediation therapies. Memory performances during a fMRI experiment will be assessed in controls and epileptic patients before and after the surgery.
The purpose of this study is to determine whether Fruitflow-II, Resveratrol (resVida), alone or in combination, are effective in the treatment of memory problems in adult patients with memory impairment. We also evaluate effects of these medications on blood flow to the brain and fitness, to find whether the possible improvement in memory is associated with the alterations in these parameters.
The Neurocognitive Study for the Aging (NEUROAGE) was initially funded by the Cyprus Innovation Foundation and has received subsequent funding by the European Union Regional Development Fund. The project focuses on the understanding of the effects of age on neurocognitive abilities such as attention, memory, language, categorization, and executive functioning. In addition, specific arms of the project investigate the effects of a theory-driven hierarchical training program, the Categorization Program, to improve cognitive abilities in adults with Mild Cognitive Impairment (MCI) and of a group intervention program focusing on cognitive and psychosocial abilities. Over 1000 adults ages 40 and older have been recruited in the NEUROAGE project thus far. The grant was awarded to the University of Cyprus, with Professor Fofi Constantinidou as the PI.
