Filter by:This ClincialTrials.gov record originally corresponded to the protocol approved under IRB # 202370. The study was expanded to include stimulation and recordings approved under new IRB #211037. The participant data originally acquired from IRB# 202370 will be included in this new record: This study seeks to better understand the neural activity underlying neuro cognitive disorders. Resting state local field potential recordings will be collected from medically refractory epilepsy patients implanted with depth electrodes for seizure localization, and metrics of neural activity will be correlated with psychiatric symptoms as measured from questionnaires. Subjects will also participate in neuro cognitive tasks while neural recordings are performed, and/or receive neural stimulation through implanted depth electrodes. A better understanding of disordered neural activity underlying neuropsychiatric disorders may additionally contribute to novel methods for diagnosing, treating, and preventing these diseases.
The purpose of this study is to see if stimulation of the brain can improve memory. The investigators will use a device called transcranial magnetic stimulation that can stimulate and activate a specific part of the brain that is important for memory. The study will enroll MCI subjects and subjects with subjective memory complaints who will be randomly assigned to receive active or sham brain stimulation. 'Blinded' or 'sham-controlled' means that the subject will not know whether the treatment they receive is the active treatment or the non-active stimulation. In the 'sham' condition, the stimulator will turn on but will not actually be stimulating the target brain region.
Memory performance is shown to be affected by age stereotypes among older adults. The purpose of the study is to examine the effects of age stereotype primes on episodic memory using priming intervention. The moderating effects of social participation is also examined.
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 aim at developing a regional database, which includes the patient medical records on a prospective basis, in collaboration with the medical and administrative staff and with the University hospital computer science departments. The main objective is to study the predictive factors associated with change in functional autonomy level, measured every 6 to 12 months in centres across Region Auvergne Rhone-Alpes in France. The real-life study population will consist in about 5400 patients with ADRD. The inclusion period will be of 3 years, the length of follow-up of each patient will be of 10 years max for a total study length of 13 years.
Complaints about memory loss are very common in women in the menopausal transition period. The effectiveness of estrogen replacement therapy in cognitive improvement is controversial. Partial positive results were obtained in some studies with regard to memory improvement, so far no standard treatment considered effective in these cases. Effective pharmacological approaches to the treatment of memory loss associated with menopause are an unmet medical need. Cogmax® is a multivitamin and mineral supplement that contains numerous key elements for cognitive function, and may be a safe therapeutic option in these cases. The multicenter, non-comparative (single-arm) phase IV clinical trial will be conducted with 80 female participants aged 45 to 60 years and menopausal memory loss complaint. After 3 months of using multivitamin and mineral supplement, memory and attention will be reevaluated through specific questionnaire and the Stroop Test Victoria version.
In 2013 an estimated 5 million people age 65 and older had Alzheimer's disease. Longer life spans and aging baby boomers will cause this number to grow rapidly. More than 50% of residents in assisted living and nursing homes have some form of dementia or cognitive impairment and the number is increasing every day. As a form of person-centered, non-pharmacological dementia care, Reminiscence Therapy (RT) holds considerable promise. Improvements in mood, quality of life, social interaction, cognition, memory and a reduction in caregiver stress have been noted. This project will develop an operational model for identifying and producing 3D personal objects using 3D printing technology, and deploying them for use in RT. The research also will evaluate the effectiveness of using 3D-printed objects in RT compared to other types of memory stimuli. This novel approach to the "personalization" of reminiscence therapy will result in better social and mental health outcomes for individuals with dementia.
This is a pilot study of non-invasive transcranial magnetic stimulation (TMS) to improve memory in healthy adults. It will also examine treating memory deficits in older adults with amnestic mild cognitive impairment (aMCI), a condition that frequently precedes Alzheimer's disease (AD. The study will test whether a form of non-invasive brain stimulation repetitive transcranial magnetic stimulation (rTMS) can improve memory abilities in healthy young adults, healthy older adults, and older adults with aMCI by retuning memory-related brain networks. This study is a key first step which will support the long-term goal of treating memory deficits in neurological patients. It is expected that rTMS will improve memory abilities in all participants, and that the improvements in memory will be attributable to changes in the connectivity of memory-related brain networks.
A debilitating and common symptom in Gulf War Illnesses (GWI) is the inability to retrieve words. This affects one's conversations, ability to fluidly exchange information verbally and retrieve information from memory. The investigators have discovered 3 brain regions - the PreSupplementary Motor Area (preSMA), caudate nucleus, and the thalamus - that are essential for word retrieval. They have also detected abnormal EEG signals related to these regions in GWI patients who have problems retrieving words. The investigators have used their model of verbal retrieval to design a noninvasive, nonpharmacological treatment that uses High Definition transcranial Direct Current Stimulation (HD tDCS). Using HD tDCS, they deliver small amounts of electric current to areas of the head to stimulate specific brain regions. The objective is to determine if delivery of HD tDCS over the preSMA will improve performance in GWI veterans with a verbal retrieval deficit. The investigators will administer pre-treatment tests of verbal retrieval measures while recording brain electrical activity. They will then administer 10 sessions of HD tDCS over the preSMA (20 minutes a session) in half the veterans. The other half will go through the same procedures, except the current will not be turned on (called the sham condition). The investigators will then compare performance between the "active" and sham group and assess if the treatment had a significant effect on performing verbal retrieval tasks and if there is a change in the ERP markers to account for how the treatment worked. If the treatment is found to be effective it will be offered to those in the sham group at the study's end. The investigators predict this treatment regimen will lead to positive effects on a person's daily functions, especially improved conversational abilities, with few, if any, side effects. They hope to outline the standard procedures for physicians to perform the treatment by creating a manual on how to apply the treatment in a clinical setting so that it will be quickly available to use in multiple sites if the proposed study demonstrates that it is efficacious. This treatment can be made widely available for Warrior Transition Units, military clinics, and VA medical centers. In addition, if successful, this could potentially lead to development of other targets of stimulation to improve other cognitive deficits in GWI, and help alleviate verbal fluency deficits associated with other disorders.
Executive functioning (EF) deficits are a core, transdiagnostic feature of psychopathology and one of the strongest predictors of clinical and functional outcomes, yet there remains a dearth of treatments available for EF deficits. EF is a collection of cognitive control processes that includes working memory (i.e., maintain/manipulate data not perceptually present), inhibition (i.e., inhibit/control of attention, thoughts, behaviors) and flexibility (i.e., shift flexibly between tasks/sets). These EF subdomains are subserved by a network (i.e., cognitive control network) of frontal (e.g., dorsolateral prefrontal cortex [DLPFC]), parietal and subcortical regions, with hypoactivation in such regions often underlying EF deficits. There is a recent call in psychiatry to develop experimental therapeutics that target anomalous neural systems underlying symptomology. Repetitive transcranial magnetic stimulation (rTMS) is a therapeutic, non-invasive method of cortical excitability modulation. High frequency rTMS to the left DPLFC has an activating effect on the cognitive control network, with initial research in adults finding a subsequent enhancing effect on working memory, inhibition, and flexibility. rTMS represents a very promising potential tool to target EF deficits in psychopathology.
EPIC II (Early-Stage Partners in Care) is a research project designed to assist people with early-stage memory loss and their care partners by providing early-stage related education and skill-training sessions, held via Zoom, designed to reduce stress, enhance well-being, manage challenges, and plan for the future. Researchers will gather feedback from individuals about their experience to continue to improve programs for early-stage memory loss.
