Cognitive rehabilitation therapy is like playing games and doing puzzles to help your brain get better. Just like when you hurt your arm and need to do exercises to make it stronger, your brain can also get hurt or weak and needs special exercises to get better.
For example, let's say you had a head injury and now you have trouble remembering things or paying attention. A therapist will work with you to make games and activities that help with memory and focus. They might have you do things like remember a list of items or find things that are hidden. Over time, these activities will help your brain get better at remembering and focusing on things.
It's kind of like going to a special gym for your brain. You work with your therapist to create a personalized plan that helps your brain get stronger and better at the things it needs to do.
