Neurofeedback (NF) or EEG biofeedback is a treatment strategy used for children, adolescents and adults with ADHD. [231] The human brain emits electrical energy which is measured with electrodes. Neurofeedback alerts the patient when beta waves are present. This theory believes that those with ADHD can train themselves to decrease ADHD symptoms.
Sleep stages are characterized by spectral content of EEG: for instance, stage N1 refers to the transition of the brain from alpha waves (common in the awake state) to theta waves, whereas stage N3 (deep or slow-wave sleep) is characterized by the presence of delta waves. [107] The normal order of sleep stages is N1 → N2 → N3 → N2 → REM.
The hypothesis notes that humans spent most of their evolutionary history in hunter-gatherer societies, and it argues that ADHD represents a lack of adaptation to farming societies. Hartmann first developed the idea as a mental model after his own son was diagnosed with ADHD, stating, "It's not hard science, and was never intended to be." [1]
Certain genes influence the volume of key brain regions, which, in turn, could play a role in the development of Parkinson's disease and ADHD, a new study suggests. Parkinson’s, ADHD tied to ...
[4] [5] Prior to the DSM, terms included minimal brain damage in the 1930s. [358] ADHD, its diagnosis, and its treatment have been controversial since the 1970s. [233] [359] For example, positions differ on whether ADHD is within the normal range of behaviour, [96] [360] and to degree to which ADHD is a genetic condition. [361]
Brainwave entrainment, also referred to as brainwave synchronization or neural entrainment, refers to the observation that brainwaves (large-scale electrical oscillations in the brain) will naturally synchronize to the rhythm of periodic external stimuli, such as flickering lights, [1] speech, [2] music, [3] or tactile stimuli.
