[25] and Staats et. al [26] showed no differences in serum and plasma BDNF levels in OSAS patients compared to healthy control volunteers. These research grouped jointly OSAS with different intensity and the air desaturation index (ODI) isn’t discussed, that may account for the various results observed. Furthermore, Staats et al.[26] discovered that the BDNF amounts were dramatically reduced whenever a single nights CPAP was used as cure in these sufferers, indicating a feasible relationship between your known degrees of peripheral BDNF as well as the intermittent hypoxia in OSAS, probably caused also by an elevated brain uptake. Even if discrepancies observed among the studies may be due to different clinical variables including OSAS severity and comorbidities, altogether these findings corroborate the hypothesis that this intermittent hypoxia, common of OSAS patients, is usually associated with altered levels of BDNF. OSAS is usually a disease characterized by rAIH and sleep fragmentation which have been demonstrated to be associated with neuro-inflammation and impaired neuro-cognitive functions [20]. Our data corroborate this association since we showed that this OSAS patients T0 had a significantly lower average MoCA questionnaire score than healthy control volunteers. However, the positive correlation that we found between the BDNF serum levels and the ODI in OSAS T0 subjects is an important evidence suggesting a reaction to the state of nocturnal rAHI. This reaction appears to be neuroprotective since we also showed a significantly positive correlation between BDNF levels and MoCA score. In particular, subjects with higher BDNF values had less impairment in neurocognitive functions. Our results are in line with previous findings from Wang WH et al. [27] who found a significant and positive correlation between MoCA score and BDNF, stating the determinant role of BDNF in neuro-cognitive protection. Since BDNF increase appears to be an adaptive response to intermittent hypoxia, an effective CPAP treatment should be able to reduce BDNF release as observed by previous studies from Staats et al. [26] and Y Wang et al. [25] Although we’ve observed a minor decrease in BDNF amounts in OSAS sufferers after CPAP treatment, this (E)-ZL0420 data didn’t reach statistical significance. This may be related to an example size effect, towards the duration of CPAP treatment and/or to a far more complex and powerful legislation of BDNF discharge in response to CPAP treatment. Many evidence strongly claim that changed BDNF signaling could be linked to the pathogenesis of many neurological disorders including Huntington’s disease, Alzheimer’s disease, and despair [28]. Entirely our data (E)-ZL0420 claim that increased degrees of BDNF in OSAS sufferers may be a significant neuroprotective a reaction to the nocturnal intermittent hypoxia and rest fragmentation directed to limit the intensifying neuro-cognitive impairment regular of the condition. Conclusions Our research shows that elevated degrees of BDNF in OSAS sufferers are connected with better neurocognitive function on the MoCA check. This data shed brand-new light in the complicated pathophysiological systems of version to intermittent hypoxia connected with OSAS and claim that BDNF, released in response to intermittent hypoxia, may actually have a defensive role by restricting neurocognitive impairment.
