| Upside | With the help of notes stored in the system, PwDs can refresh their memory frequently, ask for additional details and increase their accuracy. Besides, games that involve musical elements can help them to improve their cognitive skills. |
| Downside | If the robot constantly reminds the patient of things he still remembers, the patient may get annoyed and bored. |
