Intolerance to Noise
Sounds perceived as being normal to other people can be intolerable to people who have sustained a brain injury. We should be able to filter out background noise, but a brain injury can lead to the brain needing to learn all over again what is safe to filter and what isn’t
A lot of people use earplugs to block out noise. However, it is best to see an audiologist who will be able to prescribe specific ear filters. An audiologist will also be able to diagnose and manage any particular hearing problems that may occur as a result of brain injury.
Sounds that shouldn’t be terrifying can induce states of panic and trigger the flight/fight responses, which can be extraordinarily difficult to manage.
Everyday life can be affected to the extent that people stop socialising, or they learn to go out when there are fewer people around, such as mid-morning, or mid-afternoon.
When we eat for nutrition, we include antioxidants and flavonoids found in fruits and vegetables in our diet, and these naturally help to combat the abundance of free radicals caused by oxidative stress.
