A newer study shows that people with chronic sinusitis don’t just have to contend with a stuffy nose and headache; sinusitis can also cause trouble with focus and lead to depression and other symptoms that indicate the brain is affected as well. The study was published in JAMA Otolaryngology-Head & Neck Surgery in April 2021.
What The Research Says
According to lead study author Dr. Aria Jafari, surgeon and assistant professor of otolaryngology-head and neck surgery at the University of Washington School of Medicine, “This is the first study that links chronic sinus inflammation with a neurobiological change.”
“Patients who have sinusitis often decide to seek medical care not because they have a runny nose and sinus pressure, but because the disease is affecting how they interact with the world: They can’t be productive, thinking is difficult, sleep is lousy. It broadly impacts their quality of life,” he continued.
During the study, 22 participants with moderate or severe sinus inflammation and 22 control participants underwent functional MRI (fMRI) scans in order to measure cerebral blood flow and neuronal activity. Results showed those with sinusitis symptoms had:
- Reduced functional connectivity in the frontoparietal network, affecting executive function, attention and problem-solving.
- Reduced functional connectivity in the salience network, affecting communication, social behavior and response to external stimuli.
- Increased functional connectivity within the default-mode network, associated with self-reference, mind-wandering and wakeful rest.
The extent of these effects paralleled the severity of sinus symptoms.
Behavioral and cognitive tests showed no significant deficit for these patients. However, brain scans show that subjective symptoms like poor attention and trouble with sleep may be due to subtle changes in how the brain regions that control these functions communicate with one another.
Dr. Jafari reports that the next steps for his research team involve brain scans of patients with clinically diagnosed chronic sinusitis before and after treatment.
