Chronic rhinosinusitis, which causes a persistent blocked nose and headaches among other symptoms, affects 11 percent of people in the US – and new research has found a link between the condition and changes in brain activity.
The team behind the study is hoping that the link will help explain some of the other common effects of the persistent inflammation: finding it hard to focus, struggling with bouts of depression, having trouble sleeping, and dizziness.
Finding a connection between the underlying disease and the neural processing happening elsewhere could be vital in understanding the chronic condition, along with efforts to find better and more effective ways to treat it.

The last ice age persisted for over 100,000 years. An ice-bound eternity by any stretch of the imagination, but this long winter was not completely frozen into stillness.
During the Last Glacial Period, which ended approximately 12,000 years ago, climate change existed as a powerful phenomenon, much as it does now, albeit for different reasons.
Over the course of the ice age, a series of abrupt warming episodes punctuated the coldness, each of them sending temperatures soaring (by up to 16 degrees Celsius) in temporary heat waves that flared for decades before disappearing.
These sudden phenomena, called Dansgaard-Oeschger events, took place dozens of times over the 100 millennia of the Last Glacial. But what was it that made them spark to life at all?
Australia s Black Summer Fires Have Left a Shocking Effect on Earth s Atmosphere
12 APRIL 2021
The scorching destruction of Australia s Black Summer bushfires between 2019 and 2020 provided an ominous glimpse of fire s reach in our hotter, dryer world, and the impact of the unprecedented inferno is still being measured.
Just weeks ago, scientists observed that the amount of smoke spewed from the blaze into the atmosphere rivaled that of a great volcanic eruption. Now, researchers say the giant smoke cloud was so immense, it measurably heated the stratosphere for months on end.
In a new study led by first author and climate modeler Pengfei Yu from China s Jinan University, scientists simulated the plume s emergence and evolution, showing the worst documented wildfires in Australian history left a lasting impact on the region s skies.
