The Role of Circadian Factors in Regulation of Neuroplasticity in Ischemic Stroke (Interventional)

Source: ClinicalTrials.gov · Last updated 8 Aug 2025 · Not updated for over 12 months - ask the site whether it is still open

Brief summary (registry, in English)

There is a lack of complex studies which could establish the association between genetic circadian factors with the features and short-term outcomes of ischemic stroke, as well as the effects of various auxiliary therapies for circadian rhythm modulation for neuroplasticity enhancement and improvement of short-term outcomes in ischemic stroke. The main research hypothesis is that circadian factors influence the recovery from ischemic stroke via sleep-mediated regulation of synaptic plasticity. The project aims at the investigation of the influence of combined melatonin therapy and blue light exposure on molecular circadian biomarkers, sleep characteristics, neuroplasticity markers and stroke outcome in acute stroke patients. This study is a prospective, interventional, randomized placebo-controlled trial.
