Study Overview

• Status: Recruiting
• Conditions: Dream Disorder
• Intervention / Treatment: Diagnostic test: Online questionnaire

Detailed Description

In clinical practice, there are patients complaining for numerous dreams, which negatively affect the daytime well-being of patients, although these complaints do not fall into the category of nightmares. There are currently no data on the prevalence of the phenomenon of this phenomenon. Studies conducted on small groups of patients have found that they are more likely to have chronic pain syndrome, family history of their complaints.

The proposed study will be able to provide the first data on the prevalence and concomitant symptoms of multiple dreams. This will allow the authors to give a more precise definition of this phenomenon, describe its concomitant symptoms, and evaluate the relevance of its diagnosis and treatment. The results of the study will set the stage for further clinical research on the pathogenesis and therapy approaches. The further studies are needed to explain the causes of this phenomenon to the patients and provide them with the necessary assistance.

In view of the high workload of the medical staff, and clinical centers under the COVID-19 pandemic, and in order to increase convenience for both study participants and the researchers, data for this study will be collected remotely. The implementation of the study objectives did not require a face-to-face examination of the participants. Internet-based data collection will further simplify the processing of the data. This approach to conducting the study has already shown its applicability in a number of clinical trials.

The study will be conducted at the I.M. Sechenov First Moscow State Medical University, Russian Ministry of Health, UTH No. 3, Clinic of Nervous Diseases. A.Y. Kozhevnikov, Department of Sleep Medicine.

This study plans to inсlude all participants who agreed to participate (i.e., who clicked on the button "agree" after reading informed consent form). Information about the study and link to the questionnaires and informed consent form will be spreaded in social media, student communities, and university departmental staff communities The demographic, sleep, and psychological characteristics of people with multiple dreams will be assessed. Then a statistical analysis will be performed to compare the differences in rank, continuous, and categorical variables, and perform a multivariate logistic regression.
