NCT ID: NCT06153979 Recruiting - Measles Infection Clinical Trials

Investigation of Immune Amnesia Following Measles Infection in Select African Regions

Start date: January 16, 2024
Phase:
Study type: Observational

The goal of this observational study is to investigate the effects of measles virus (MeV) infection on pre-existing immunity, vaccine response, and susceptibility to subsequent illness in children aged 1-15 either with or without acute MeV infection.

NCT ID: NCT06044740 Recruiting - Pain Clinical Trials

Sevoflurane's Effect on Neurocognition Study

SENS
Start date: January 17, 2024
Phase: Phase 1
Study type: Interventional

The purpose of this study is to determine the effects of acute pain on long-term memory and conditioned physiologic responses in the presence and absence of low dose sevoflurane. Functional magnetic resonance imaging will be used to identify the neural correlates of these phenomena. The study will occur over 2 visits and involves no long-term follow up.

NCT ID: NCT05883397 Recruiting - PTSD Clinical Trials

Enhanced Hippocampal Neuroplasticity for Surfacing of Inaccessible Traumatic Memories in Veterans With PTSD

Start date: May 25, 2023
Phase: N/A
Study type: Interventional

Hyperbaric oxygen therapy (HBOT) includes the inhalation of 100% oxygen at pressures exceeding one atmosphere absolute. HBOT has been applied worldwide, mostly for chronic non-healing wounds. Our team demonstrated that HBOT induced hippocampal neuroplasticity in veterans with long-standing treatment-resistant PTSD; this led to enhanced memory recovery and significant improvement in PTSD symptoms. Both physical activity, such as aerobic exercise, and cognitive training were shown to support neurogenesis in the hippocampus. Therefore, the current study aims to evaluate whether hippocampal training, induced by physical and cognitive training, will augment the hippocampal neuroplasticity effect of HBOT and further enhance recovery of inaccessible memories in veterans with PTSD. The protocol will include forty male veterans aged 25 to 60 years, with combat-associated PTSD and peritraumatic amnesia, who will receive either HBOT alone or HBOT and hippocampal training. The HBOT protocol will consist of 60 daily sessions, 90-minutes each, five days a week. Hippocampal training will combine physical and cognitive training 3 times per week, prior to HBOT sessions. Detailed psychological evaluation, anatomic and functional MRI, electroencephalogram and autonomic nervous system data will be obtained at baseline, and during and after treatment. The proposed study offers a new approach of biological treatment for memory manipulations. The findings will help elucidate the mechanism of PTSD-related memory impairment and is expected to contribute to the development of biological memory manipulations for treating PTSD and other memory-related conditions.

NCT ID: NCT05350085 Recruiting - Dental Anxiety Clinical Trials

Remimazolam in the Extraction of Impacted Wisdom Teeth

Start date: April 18, 2022
Phase: N/A
Study type: Interventional

Benzodiazepines, represented by midazolam, are often used for sedation in outpatient surgery in dentistry. However, midazolam has the problems of slow consciousness recovery and long recovery time, which brings trouble to the patients. Remimazolam is a new type of ultra short acting sedative anesthetic. Compared with other similar products, remimazolam has faster effect, rapid metabolism and has no accumulation, which may mean that compared with midazolam, remimazolam has a better clinical application prospect in dental outpatient surgery.

NCT ID: NCT04516863 Recruiting - Retrograde Amnesia Clinical Trials

A Validation Study of the German Autobiographical Memory Interview

Start date: August 15, 2020
Phase: N/A
Study type: Interventional

Electroconvulsive therapy (ECT) is recommended for the treatment of severe depression. But, despite the high remission rates the use of ECT is strongly limited by the social stigma and treatment-emergent cognitive side effects in patients. The most relevant is retrograde amnesia (RA), because it can persists for months and years. To measure RA after ECT the short-form of the Autobiographical Memory Interview (SF-AMI) is commonly used. However, the validation of the German SF-AMI has not yet been carried out. Thus, the aim of this study is to validate the German SF-AMI in depressed patient and healthy controls. The investigators hypothesize that the German SF-AMI is reliable and valid to quantify RA.

NCT ID: NCT04389437 Recruiting - Alzheimer Disease Clinical Trials

OCT-Angiography and Adaptive Optics in Patients With Memory Impairment

OCTAVO
Start date: June 26, 2020
Phase: N/A
Study type: Interventional

Studies suggest an association between retinal abnormalities and NCD (Neuro Cognitive Disorders) whether they are linked to proven or prodromal Alzheimer's disease (aMCI : amnestic mild cognitive impairment), or to other neurodegenerative diseases such as frontotemporal dementia or Lewy body diseases. These retinal anomalies objectified by OCT-A (Optical coherence tomography angiography) and adaptive optics (AO) appear different depending on the pathologies and could therefore serve as markers in vivo of the pathophysiological processes underlying NCD. No study to date has studied the retina and its vessels in NCD using adaptive optics. In this pilot study, we are proposing a combination of two new ophthalmological imaging techniques (OCT-A and AO), which allow rapid in vivo analysis in a completely non-invasive way of the morphology of small vessels as well as architecture of the retina to better specify the retinal anomalies associated with NCD. We will compare the parameters in OCT-A and AO between patients with NCD and controls without NCD (with memory complaint or without) and will seek to determine if there are different profiles according to the causes of NCD.

NCT ID: NCT02576821 Recruiting - Clinical trials for Patients With Cognitive Disturbances

Hippocampal Sclerosis and Amnesia Not Due to Alzheimer's Disease

ShaTau7
Start date: January 27, 2016
Phase: N/A
Study type: Interventional

Hippocampal Sclerosis (HS) leads to anterograde amnesia mimicking early Alzheimer's disease (AD) (so called HSA-nonAD). Recent studies showed that (a) the deficit of episodic memory as well as the level of hippocampal atrophy in bvFTD may be of similar severity to that observed in AD, even at initial presentation, leading to misdiagnosis in 22% of cases with post mortem diagnosis; (b) amnesia with HS due to microvascular lesion and microinfarcts can also cause impairment of episodic memory mimicking AD, without subcortical cognitive profile. Because these diseases involve distinct pathophysiological processes, they require different specific care and treatment. In consequence, it is very important to improve our knowledge about HS in order to identify its mechanism and improve the diagnosis.

NCT ID: NCT01793168 Recruiting - Clinical trials for Retinitis Pigmentosa

Rare Disease Patient Registry & Natural History Study - Coordination of Rare Diseases at Sanford

CoRDS
Start date: July 2010
Phase:
Study type: Observational [Patient Registry]

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
