The purpose of the research conducted in this article was to analyze how sleep quality affects the brain. The research question was whether sleep quality was associated with cortical and hippocampal volumes, as well as measures of atrophy in the brain. It has been hypothesized that poor sleep quality is associated with decreased volume and increased atrophy in the orbitofrontal cortex and medial prefrontal cortex. Say no to plagiarism.

Subsequently, a second MRI was performed between 2011 and 2012. Finally, between 2012 and 2013 it was An assessment of sleep quality was tested. The same MRI scanner and process remained the same throughout this study. MRI images were processed individually followed longitudinally. The Sleep Quality Assessment was a questionnaire used to evaluate the seven domains of sleep quality. The researchers also analyzed other factors such as physical activity, BMI and blood pressure. The factors were measured when participants presented for the second MRI through appropriate questionnaires and tests. At T2, cross-sectional cortical analysis was performed on each brain vertex as the dependent variable. The PSQI score resulting from the sleep analysis was used as an independent variable. Similarly, the longitudinal cortical analysis used a general linear model to study the volume change from T2 and T1. The volume change measured in each cortex was the dependent variable while the PSQI score was the independent variable. The influence of outliers and other possible effects such as physical activity and BMI were also taken into account. All of this data was then used to determine which aspects of sleep align most closely with the findings. The results of this research established that poor sleep quality was linked to volume reduction in the superior frontal cortex. Furthermore, poor sleep quality was associated with greater atrophy in the frontal, parietal and occipital lobes of the brain. It was also determined that other factors such as physical activity, BMI, and blood pressure were not associated with sleep analysis score or PSQI. These findings are in line with the hypothesis that poor sleep quality is linked to decreased volume while increasing atrophy in the orbitofrontal cortex and medial prefrontal cortex. The goal of the CNN article was to summarize research conducted on how poor sleep affects the brain. They explained that the study was tested with two MRI scans and a questionnaire on the participants' sleep habits. The data they concluded stated that those with poor sleep patterns showed a more rapid decline in brain volume. It was also concluded that subjects over the age of sixty exhibited these patterns more. The purpose of the article was to point out that inadequate sleep patterns can lead to brain disorders that cause memory loss, thus shrinking our brain. At the end of the article they chose three statements from the original article. All three statements lead to the fact that further testing is needed and that there are many questions to be resolved. The author of the popular press article uses causal language when he states that lack of sleep affects the size of our brains. It is not possible to draw causal conclusions from the.
