Executive Function Deficits

ADHD is usually due to a depletion of certain chemical messengers in the front part of the brain. The major cause of this depletion relates to a number of defective genes. ADHD shares some of its causative genes with certain other conditions, so having ADHD makes also having these other conditions more likely. To help many children with learning and behavioural difficulties, we need to treat an impairment in their brain function. This chapter discusses impairment in brain function as a cause of ADHD, including executive function deficits, frontal lobe underactivity, neurotransmitter depletion, gene defects, and non-genetic factors. It also describes the mechanism of comorbidity.

Chemical Messengers

Neurotransmitters are important chemical messengers in the nervous system that play a crucial role in physiological and physical health. Abnormal levels of neurotransmitters have been correlated with physical, psychotic, and neurodegenerative diseases such as Alzheimer’s, Parkinson’s, dementia, addiction, depression, and schizophrenia. Although multiple neurotechnological approaches have been reported in the literature, the detection and monitoring of neurotransmitters in the brain remains a challenge and continues to garner significant attention. Neurotechnology that provides high-throughput, as well as fast and specific quantification of target analytes in the brain, without negatively impacting the implanted region is highly desired for the monitoring of the complex intercommunication of neurotransmitters. Therefore, it is crucial to develop clinical assessment techniques that are sensitive and reliable to monitor and modulate these chemical messengers and screen diseases. This review focuses on summarizing the current electrochemical measurement techniques that are capable of sensing neurotransmitters with high temporal resolution in real time. Advanced neurotransmitter sensing platforms that integrate nanomaterials and biorecognition elements are explored.

Chemical Messengers

According to the late Sir William Bayliss, a leading physiologist, the vitamins, which the plant alone knows how to manufacture, are a kind of chemical messengers (hormones). “They are obtained from the plant, and are particularly abundant in fresh green vegetables and fruit.” … “Their precise mode of action is still unknown, but in their absence normal growth and function is impossible and certain diseases make their appearance.” Hence the normal growth of the animals depends upon stimulations and influences directly derived from the plant kingdom. The evolution of the animal is in large part directed by the plant, which is also saying that it is cosmically directed, in virtue of those terrestrial and solar influences which the plant purveys. But it is also saying, in a most important sense, that all organic evolution is directed by the amount of mutuality existing between the kingdoms and what this involves in bio-sociality. If the vitamins are, in Sir William's words, “obviously a kind of chemical messengers,” then we must consider them as the hormones of symbiosis, as “messengers” of health—the diametric opposites of the alkaloids, the vegetable poisons which are of appalling efficacy in the physiological economy of the animal. By symbiosis I mean not parasitism, not commensalism, but definite, almost deliberate, mutual adaptation for the purpose of mutual service, on the part of living things, nearly always of different orders of creation, broadly, that is, between the plant and the animal (“Norm-symbiosis”).
