Filter by:The purpose of this clinical trial is learn whether a behavioral (non-medication) treatment can reduce nightmares in adults with narcolepsy. All participants will receive the treatment and will complete three assessments. Half of the participants will receive the treatment after the first assessment, and half will receive it after the second assessment.
The purpose of this research study is to assess the safety and efficacy of ALKS 2680 compared to placebo, including whether participants taking ALKS 2680 experience a greater decrease in sleepiness and a decrease in cataplexy ("sudden loss of muscle control"), compared to participants taking placebo alone.
The main objective is to examine the potential mentalization impairments affecting a population suffering from narcolepsy type 1. Indeed, the hypothesis of this research is that mentalization could be impaired in narcoleptic patients.
Narcolepsy type 1 (NT1) is a rare disease characterized by severe drowsiness, cataplexy, hypnagogic hallucinations, sleep paralysis, poor night sleep, and often obesity. NT1 is caused by irreversible loss of orexin (ORX)/hypocretin neurons in the lateral hypothalamus with decreased ORX levels in the cerebrospinal fluid (CSF). Although the underlying process leading to this destruction remains unclear; an autoimmune origin is suspected. The study authors recently compared the bacterial communities of the fecal microbiota of NT1 patients and control subjects. Initial results demonstrated a difference in overall bacterial community structure in NT1 compared to controls, as assessed by beta diversity, even after adjusting for body mass index (BMI). The Shannon biodiversity index was also correlated with the duration of NT1 disease. However, no association was found between the structure of the microbial community and the clinical characteristics of NT1 patients. In 2022, a second study from the SOMNOBANK cohort on a larger population confirmed these results, showing dysbiosis between NT1 patients and the control population. The altered intestinal microbial diversity supports the important role of the environment in the development and pathogenesis of NT1. Other studies have established a link between dysbiosis, intestinal permeability and inflammation in other neuroimmune pathologies. Currently, no study has focused on these phenomena of bacterial translocation, intestinal permeability and immune activation linked to the microbiota in type 1 narcolepsy patients. The study hypothesis is that NT1 patients with dysbiosis in their intestinal microbiota also present a bacterial translocation with an intestinal origin, leading to a systemic inflammatory syndrome favoring an autoimmune damage destroying hypocretin neurons in the hypothalamus. The study authors suspect that microbial elements (DNA) involved in the autoimmune process could be detected in the CSF. This bacterial translocation could vary over time depending on: i) the progression of the disease and its management; ii) changing dysbiosis and: iii) the increase in intestinal permeability and inflammation.
The goal of this study is to test a web-based psychoeducational resource for adolescents with central disorders of hypersomnolence and their families. The investigators hope to assess the website's usability, acceptability, and feasibility, as well as its potential effect on social relationship health. Participants will be asked to review the content of the psychoeducational websites. The participants will then provide feedback on the website, as well as the adolescent's social relationships and social health before and after reviewing the website through online surveys.
The study aimed to examine the efficacy and safety of tVNS as a complementary approach for NT1 by conducting a double-blind, randomized, sham-controlled trial. The specific objectives of the study were as follows: To evaluate the effects of complementary tVNS on the ability to maintain wakefulness, severity of narcolepsy, mood and quality of life in patients with NT1
The goal of this pilot observational study is to assess the ability of continuous 'home' EEG to accurately diagnose Narcolepsy in children and young people with hypersomnia. The main question[s]it aims to answer are: - can ambulatory home monitoring using a Dreem headband with a 'life as usual' unrestricted protocol allow accurate diagnosis of Narcolepsy, compared to gold standard in-patient PSG and MSLT - which EEG derived sleep parameters and study duration yield most diagnostic accuracy Participants undergoing investigation for hypersomnia will additionally be asked to wear a Dream Headband at night for weeknights, then continuously for 48 hours over the weekend. The data from the headband will then be analysed to see if it can predict the results of the polysomnography and MSLT that form routine clinical care.
This study is part of the research on type 1 narcolepsy, a neurological pathology affecting mostly young subjects. The only biomarker currently available is the hypocretin assay, which shows a level below 110 pg/mL. However, the interpretation of this biomarker has limitations: the test is not widely available and it is rarely performed by practitioners. Even when performed, the interpretation of the level may not be consistent with the phenotype compatible with type 1 narcolepsy. This study therefore aims to develop new tools to reduce the diagnostic delay. This would be the first study with 7T MRI that could achieve a level of spatial resolution sufficient to highlight volume changes in small brain structures such as the lateral hypothalamus whose narcolepsy-induced changes are not detected by lower resolution MRI.
The goal of this clinical trial is to see how NLS-2 (mazindol extended-release) works on symptoms of narcolepsy, including cataplexy and excessive daytime sleepiness. Approximately 48 participants will take part in the study across the United States. The study treatment (NLS-2 or placebo) will be administered for 8 weeks. After this treatment period, the participant may have the option to participate in a separate long-term extension study during which all participants will be treated with NLS-2.
The main aim is to evaluate the safety and tolerability of TAK-861 on participants with type 1 and type 2 narcolepsy from previous parent studies, TAK-861-2001 (NCT05687903) and TAK-861-2002 (NCT05687916).
