Lumosity games do not necessarily build new neural pathways. Many just cause lazy neural pathways to become better functioning. Many brains have rarely tried to use the functions that are exercised by Lumosity and other brain training programs.

Establishing new neural pathways is a slow and long process. It takes months and years to establish new pathways. Just consider how long it takes an infant to establish them as the infant grows through childhood to adulthood.

The person who was comatose for a long period often needs to awaken neural pathways that were dormant during the coma. Once these dormant pathways are reawakened, then there is a concerted effort to establish new pathways for pathways lost to the injury. This is a slow and long process.

Lumosity is good exercise for gaining new skills or strengthening weak skills but it is not a healing/recovery program.Often, by gaining new skills or strengthening weak skills, one can develop work-arounds and accommodations to overcome lost functions. That is the key focus on brain injury rehabilitation.
