Neuroplasticity is a relatively new concept in neurology.
When we were medical students, we were told that the nervous system, after full growth, will not change any more. This understanding would leave little hope for injuries to the central nervous system. Also, when it came to the mental health issues, many studies showed physical changes in the hard wiring of brain as a source of these conditions. But how could we have any hope for change if the hard wiring of brain will never change after it is established?
The good news is our brain can change and the nerves are flexible. This is called neuroplasticity. It becomes very important for patients with depression and anxiety. For example, meditation can change the brain for better function and help depression.
There is hope for change and improvement especially when it comes to the wiring and function of our brain.
