Neurofeedback (NF) or EEG biofeedback is a treatment strategy used for children, adolescents and adults with ADHD. [234] 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.
There are a wide variety of symptoms that have been found to be associated with sensory overload. These symptoms can occur in both children and adults. Some of these symptoms are: Irritability "Shutting down," or refusing to participate in activities and interact with others; Over-sensitivity to touch, movement, sights, or sounds
Some ADHD symptoms in adults differ from those seen in children. While children with ADHD may climb and run about excessively, adults may experience an inability to relax, or may talk excessively in social situations. [57]: 6 Adults with ADHD may start relationships impulsively, display sensation-seeking behaviour, and be short-tempered.
ADHD medication tied to 19% lower death risk. An observational study conducted in Sweden, whose results appeared in JAMA in March 2024, further emphasized the positive impact of ADHD medication on ...
Alpha waves again gained recognition in the early 1960s and 1970s with the creation of a biofeedback theory relating to brain waves (see below). Such biofeedback, referred to as a kind of neurofeedback, relating to alpha waves is the conscious elicitation of alpha brainwaves by a subject. Two researchers in the United States explored this ...
Although Weikard mainly described a single disorder of attention resembling the combined presentation of ADHD, Crichton postulates an additional attention disorder, described as a "morbid diminution of its power or energy", and further explores possible "corporeal" and "mental" causes for the disorder (including "irregularities in diet ...
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.
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.
