Neuroplasticity is how our brain adapts and changes. But this process has some challenges:

1. Hard to Recover: When brain cells, called neurons, get hurt, they often can't grow back or make new connections. This can make it tough for people to fully recover from injuries.

2. Learning Changes with Age: As we get older or when there are certain brain issues, our brain’s ability to change and adapt can get weaker. This affects our learning.

3. Many Factors at Play: There are lots of different signals in the brain. These can make it hard for scientists to figure out exactly how everything works together.

Possible Solutions:

• Scientists are looking into special proteins called neurotrophic factors. These could help improve how our brain changes and learns.
• Some targeted therapies, like rehabilitation programs, might help people recover better, even with the challenges they face.
