And the medical research profession is working on devices or implants that will provide gentle electrical currents to the brain to keep whatever part of the brain is not functioning normally (whatever that is) calm. I don't know if 'calm' is the right word to use to describe it, but I think about it as keeping the brain from going to extreme highs or lows.
Of course, when/if these treatment options become available, many people will refuse them because their beliefs and illness will not allow them to accept them.
Very sad.
