Two people with ADHD for example could have completely different ADHD subtypes. One could have inattentiveness as the primary symptom as a result of high theta waves, and the other could have high beta-2 waves as feel hyperactive. While generalized entrainment protocols should be studied, it is important to consider that each person may respond differently to the protocols; each person has a unique neural footprint.
If brainwave entrainment leaves you with unwanted side-effects (see below) or discomfort, you’re probably encouraging a range of brainwaves that are already excessive in some area of your brain. The way around this is to get a brain map to see what your brain’s strengths and weaknesses are, and see what (if any) brainwaves could use some encouragement.
