Which of the following is a common symptom that may persist after a concussion?

Sleep disturbances are a common symptom that can persist after a concussion. Following a traumatic brain injury, individuals often experience various sleep-related issues, such as difficulty falling asleep, maintaining sleep, or experiencing excessive daytime sleepiness. These disturbances can be attributed to changes in brain function and neurotransmitter levels that occur as a result of the injury. Individuals may also experience other factors that contribute to sleep issues, such as anxiety, depression, or pain, which are also common after a concussion.

Understanding the impact of concussions on sleep is crucial for both recovery and rehabilitation, as inadequate sleep can exacerbate cognitive deficits and impede the healing process. Proper management of sleep disturbances is an essential component of treating individuals recovering from concussions.
