Sleep, Cognition, and Communication
Many people experience changes in their sleep after a brain injury. 12,13 In the early stages, immediately following, people usually feel sleepy and need extra sleep. 14,15 They may also need to nap or sleep during the day. Despite needing extra sleep, some people find their sleep isn’t restful.
Once the initial symptoms of a concussion/brain injury settle down, some people go on to have difficulty falling asleep, staying asleep, or getting restful sleep. We know that women experience more challenges with sleep after a concussion than men. We also know that a history of migraines, continued headaches, and mood challenges are also related to poor sleep.
Why is this important?
This is important for a number of reasons. When sleep is poor, it has a negative effect on our ability to pay attention and remember. It contributes to that feeling of brain fog and slowed thinking. When sleep is poor, or a person doesn’t get enough sleep, it has a negative effect on mood and can increase irritability and depressive feelings.
Poor sleep also affects how we communicate. It makes it harder to find the right words to organize and express thoughts and ideas. It can also affect social communication by making the person more irritable or emotional. As a result, a person may say things they regret later or be more confrontational.
