The purpose of this study was to examine the relationship between snoring and obstructive sleep apnea/hypopnea index in community dwelling older men and women. In this retrospective case-series study, the author was using a sequential collection of clinical datum design. There were 124 community-dwelling elders (mean age=71.85 years, Standard Deviation=4.85 years) with complaints of sleep disturbance. Including 46 females (F: M= 1:1.71), all the total subjects with sleep disturbance, after meeting the following criteria of exclusion: age below 65 years, heart failure, and chronic obstructive lung disease, were admitted to the sleep medicine laboratory where sleep questionnaire was used. They underwent in laboratory over-night polysomnography (PSG). The period of this study was 13 months; the total number of subjects whom took PSG in this Sleep Center Laboratory was 1,087 individuals during this period. The proposed neural model used is a generalized regression neural network (GRNN). This neural model has some advantages such as cost and time efficiencies in relation to experimental measurements. The training speed of the proposed technique is faster and the network architecture is simpler. In all likelihood, this model can be used in clinical applications that can reduce the necessity of in-laboratory nocturnal sleep studies since it has surpassed current classification approaches in terms of accuracy, simplicity, cost, time efficiency, and generalization. The correlation between snoring and AH1 was evaluated, though there was no measurement of vasopressin-positive and vasoactive-intestinal-polypeptide (AVP) neurons in postmortem examination of suprachiasmatic nucleus (SCN), as there was no death case. To the contrary, focus was set on the analysis of sleep disturbances that could be interpreted as the result of altered SCN function. The relationship between Snoring and AHI for the elderly with regard to its clue and impact on INSOMNIA is presented. The relationship between clinical sleep apnea and the physiological events surrounding the octogenarians was assessed. Clinically no indication for any brain tissue biopsy.
