Neurofeedback brain-training is an energy intervention.  It improves the brain’s ability to produce a range of energy levels, to reduce levels of inflammation and hyper-sensitivity, to communicate efficiently within itself, etc.

There are physical issues like Parkinson’s (the death of dopamine-producing neurons), Alzheimer’s (physical blocks by amyloid plaques within synapses), loss of myelin sheaths on axons which slow down transmission in disorders like MS or ALS, white-matter brain injuries which sever neurons from the communication systems, etc.  Training energy patterns cannot resolve these problems, though in many cases they can reduce the symptoms.

You cannot fix physiological brain issues by changing energy patterns, but it’s very likely you will see improvements by helping the brain to learn to function more effectively in the physical environment in which it finds itself.  It’s certainly worth a try, as there’s no good reason for expecting that it will have any kind of negative effect.
