Multitasking relies heavily on executive function, the brain's system for juggling priorities, switching attention, and filtering out distractions. A brain injury can disrupt this system even when other abilities seem largely intact. This means someone might:

• Lose track of a conversation while trying to do something else
• Feel mentally exhausted after tasks that used to feel routine
• Make small errors when handling multiple steps at once
• Need to complete tasks one at a time instead of in parallel

This isn't a permanent limitation for most people. With the right rehabilitation approach, many patients rebuild this capacity gradually, though the timeline varies based on injury severity and individual factors.
