Direct Neurofeedback and LENS Neurofeedback (LENS) emit different types of waves, depending on whether we are in a focused state or daydreaming. The goal of neurofeedback is to teach a person to produce brain-wave patterns that reflect focus.
The result: Some ADHD symptoms diminish. Neurofeedback doesn’t try to reproduce a certain brain wave, but rather enhances the brain’s ability to adapt to a task, whether it be taking tests in school or struggling to get along with friends.
In particular, LENS has had extraordinary results using weak electromagnetic fields to stimulate brain-wave activity and restore brain flexibility. A study of 100 subjects with different diagnoses — ADHD, traumatic brain injury, bipolar disorder — showed that 90 percent of them did better after LENS.
