Description
Technical field
The present invention relates to a kind of reaction type attentional regulation headring.
Background technology
Attention deficit hyperactivity disorder (Attention Deficit Hyperactivity Disorder, ADHD) is one
The common infantile psychology behavioral problem of class, its symptom is mainly shown as that notice laxes or concentrate difficulty, and activity is excessive, self-control
Power is weak etc., and current China there are about the ADHD infants of 1461-1979 ten thousand.The psychology of children and youth and mental health protection are one non-
Often important sociology problem, also carries the happiness of countless families.Therefore, timely diagnosis, education and treatment to ADHD
Techniques or methods are in the urgent need to new breakthrough and progress.
With the development of scientific research, the parsing with cognitive abnormal neurology basis and mechanics is noted ADHD,
People gradually recognize that this kind of phrenoblabia is due to the function of Prefrontal Cortex Cortical neurons loop and anomaly existing for activity
Association, majority think that ADHD is caused by a kind of genetic dopamine metabolism for betiding Prefrontal Cortex is not normal
, current research thinks that the pathobolism of Norepinephrine can also affect the state of an illness.On electroencephalogram (EEG), it has been found that
The brain wave Frequency downshift of ADHD infants, i.e., β ripples (14-30Hz) activity of commissarial excitatory state is reduced, mainly α ripples
(4-7Hz) with θ ripples (8-13Hz) composition, hyperactivity infant causes functional disorders of brain due to the exception of cerebral nerve loop, to big
The regulating power of Cerebral cortex is not enough, thus just can be in generation behavior it is out of control.For the treatment of ADHD infants has at present various sides
Case, including drug therapy, behavior intervention, neural feedback training technique etc..
In drug therapy, the medicine main component for clinically using include methylphenidate, dextro-amphetamine, atomoxetine and
Amphetamine etc..But, although clinically conventional medicine has obvious therapeutic effect to ADHD, these medicines are simultaneously adjoint
Side effect, children and adolescents physical development can be affected, and pharmaceutically-active real-time is poor, it usually needs and several days are very
To the time up to the several months.
Behavior intervention therapy mainly by patient is implemented depending on, listen, say, tactile, the various stimulations naturally such as proprioception.
Its general principle is that these stimulate the stimulus signal for producing eventually to reach brain each cortex by Nervous pathway naturally,
It is the neutral net of an interaction between cortex, these stimulate the tune that infant perhaps can be aided in self neural activity naturally
Section, so as to reach the control to behavior.Behavior intervention therapy is all that nature stimulates due to what is adopted, in the rational feelings of stimulus intensity
Under condition, side effect will not be produced substantially.But this mode is lacked due to theoretical foundation, and which kind of stimulation form and stimulation are taken actually
Parameter all not good theory used as guidance, and effect is also general, it is difficult to there is significant effect.
Neural feedback training technique is based on and abnormal nervous activity information is extracted from noninvasive EEG signals, by interaction
The task of formula actively adjusts the purpose that E.E.G reaches rehabilitation training patient.Neural feedback training technique is obtained by extracting brain wave
To brain activity abnormal information, combined training task, targetedly feedback regulation is realized, action effect is notable.But due to logical
Cross training normal form therapy mechanism it is unclear, limit treatment normal form optimization, and neural feedback training need specialty
Trainer is instructed and is aided in, and along with the training time is long, can not be promoted well.
