Objective: The primary and secondary consequences which related to obstructive respiration to occur during sleep cause cognitive, emotional and behavioral changes indirectly. Aim of the present study was to evaluate quality of sleep and relationship between quality of sleep and cognitive function at baseline and during treatment in the patients having diagnosis of severe Obstructive Sleep Apnea syndrome (OSAS) being followed in sleep laboratory. Materials and Methods: Pittsburg, Epworth and Stroop tests to assess patient attention; P300 test was applied for the evaluation of memory and attention. Results: When the pre-treatment and post-treatment cognitive functions of the patients were compared; there was a significant decrease in daytime sleepiness after treatment (p=0.000) and a significant improvement in latency of P300 test (p=0.000-p=0.001-p=0.004). In Pittsburgh study; the pre-treatment total sleep quality scores were consistent with poor sleep quality, while the mean value obtained after treatment was found to be related to the healthy sleepiness (p=0.000). In the Stroop test for measuring attention, the rate of error correction obtained after treatment was significantly improved (p=0.010). Conclusion: In patients diagnosed with severe OSAS; the negative effects of disease on attention, alertness, and memory, challenges on maintaining the attention and its negative effects on the structure of sleep has been shown by using Stroop, Pittsburgh, P300 and Epworth tests unlike other publications. As a result of the tests performed after the treatment, the fact that it is an important development in the disease shows us how the treatment is important and necessary.

Investigation of Sleep Breathing Disorders in Young Patients (under 55 Years) With Mild Stroke
(Elsevier, 2020) Kisabay, Aysin A. K.; Saritas, Aysegul Seyma; Batum, Melike; Goktalay, Tugba; Horasan, Gonul Dinc; Selcuki, Deniz; Yilmaz, Hikmet
Introduction: Many patients with stroke also have sleep breathing disorders (SBD), most of which is obstructive sleep apnea (OSA). Methods: Sixty patients with a history of stroke aged under 55 years were included in our study. The demographic characteristics (age at stroke, sex, body mass index) of the patients and etiology of stroke was evaluated according to the Trial of Org 10712 in Acute Stroke (TOAST) classification. The National Institute of Health Stroke Scale (NIHSS) and Modified Rankin Scale (MRS) were used to evaluate functionality. All patients underwent polysomnography (PSG) investigations. Findings: Based on PSG investigations, seven patients were normal, 10 had primary snoring, and 14 had mild, 11 had moderate, and 18 had severe OSA. The demographic characteristics did not differ significantly between the groups. No significant correlation was found between disease severity and NIHSS, MRS or TOAST classifications. Large artery atherosclerosis in the etiology, facial paralysis and dysarthria in the neurological examination, and brain stem involvement in the stroke location were observed to accumulate in the severe OSA group. When the anterior system, posterior system, and association of both were compared for vessel location, no significant difference was found regarding circulatory systems. Conclusions: It is considered that SBD has also a role in the etiology of stroke in patients aged under 55 years, and it should be taken into consideration as much as other risk factors. This is the first study to emphasize the importance of this topic in the literature.
