Obstructive sleep apnoea (OSA) is one of the most common sleep disorders, significantly increasing the risk of cardiovascular disease. Until now, it was believed that its causes were primarily anatomical factors and upper airway obstruction.

However, research conducted by scientists from the Hirszfeld Institute, in collaboration with researchers from the Wrocław Medical University, proves that OSA also has significant neurobiological and genetic causes. A study published in the renowned journal „Annals of Medicine” reveals a strong correlation between obstructive sleep apnoea and blood dopamine levels.

The results are groundbreaking and change the way obstructive sleep apnoea is perceived. They pave the way for personalised diagnostics, offering the chance for more effective treatment.
