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.
The study will investigate the influence of combined blue light exposure and melatonin therapy on molecular biomarkers of circadian rhythms, sleep characteristics and stroke outcome in acute stroke patients This study is designed as a prospective study in acute stroke patients (approx 80 patients) admitted to the Stroke Unit. After initial assessment, the participants will be randomly assigned in 4 groups (the treatment or control) with approx.20 participants in each group.
In all participants, the following parameters will be assessed: medical records, stroke characteristics, sleep characteristics, cardiovascular circadian rhythms and blood samples for the evaluation of circadian molecular biomarkers at baseline and 14 days after inclusion. Stroke outcomes will be reassessed at 3-month follow-up.
The following associations will be assessed:
