Our senses are constantly being bombarded with information from our surroundings – the sights, sounds, sensations and smells around us, as well as the tastes in our mouths.
The brain has to work hard to process all this information simultaneously, and filter out what’s irrelevant so we can concentrate on what’s important at any given moment. But this ability can be impaired in people with certain clinical conditions, leading to a disabling hypersensitivity to the stimuli around them.
The resulting physical and mental overload can lead to poor coordination, dizziness, clumsiness, numbness, tingling and nausea, and may affect individuals’ ability to take in information and make decisions.
Dr Sanjay Kumar, Dr Farzaneh Yazdani and colleagues at Oxford Brookes University have previously looked at this phenomenon in people with post-concussion syndrome following head injury. And we recently awarded funding to the team to investigate the problem in ME/CFS.
