Studies indicate exercise may help improve the the links in the nervous system between separate brain areas, improving brain health.The study matched 2,093 patients with OSA and a cancer diagnosis that occurred up to five years before their OSA diagnosis to a control group of the same size that had OSA but not cancer. Researchers measured the severity of the sleep disorder using the apnea hypopnea index or the oxygen desaturation index .
“The findings in this study highlight the need to consider untreated sleep apnoea as a risk factor for cancer and for doctors to be aware of the possibility of cancer when treating patients with OSA,” the study authors wrote. “However, extending screening for cancer to all OSA patients is not justified or recommended by our study results.”
“We found that OSA and, in particular, low oxygen levels during sleep due to OSA, was associated with a greater decline in global cognitive function, processing speed, executive function and verbal memory,” said Raphaël Heinzer, director of the Centre for Investigation and Research on Sleep at Lausanne University in Switzerland. “We also found that people aged 74 and older and men were at higher risk of cognitive decline related to sleep apnea in some specific cognitive tests.
