A Canadian study of over 30,000 older adults suggests a 40% higher likelihood of mental health conditions, including anxiety and mood disorders, for those with obstructive sleep apnoea (OSA). The research, published in JAMA Network Open, followed participants for three years and found this increased risk remained consistent over time. Factors like being female, having lower income, or poorer health were also associated with higher risks of new mental health conditions. The findings emphasize the need for mental health screening in older adults at risk of OSA.
