Do the effects of neurofeedback last?

Yes!  And this is what we find so exciting about this type of brain training.  Unlike medications which require you to "be on" them in order to feel the effect, this type of brain training lasts and begins to be your "new normal."  We simply need to understand the concept of neuroplasticity in order to begin to understand why this is the case.  When we are working at the electrical brain wave level, we are "re-wiring" the brain which can have long lasting effects. 

Neurofeedback is actually a learning task.  You get results because your brain is actively learning, even if you are not doing the learning consciously.  So much like reading, once your brain knows how to read, it can't "not know."  Your brain doesn't forget.  It may get rusty, but the effects of learning through your lifetime.
