Children not diagnosed with hyperactivity show no change in retention rates due to use of stimulants such as methylphenidate or pemoline. [11] [26] These studies validate the prescription of stimulants for individuals with hyperactive disorders. The results show that the state of consciousness produced through use of these drugs improves ...
In 2008, stimulants, such as caffeine, were the most commonly used nootropic agent. [15] In 2016, the American Medical Association adopted a policy to discourage prescriptions of nootropics for healthy people, on the basis that the cognitive effects appear to be highly variable among individuals, are dose-dependent, and limited or modest at ...
Stimulants can affect various functions, including arousal, attention, the reward system, learning, memory, and emotion. Effects range from mild stimulation to euphoria, depending on the specific drug, dose, route of administration, and inter-individual characteristics.

Use of stimulants may cause the body to significantly reduce its production of endogenous compounds that fulfill similar functions. Once the effect of the ingested stimulant has worn off the user may feel depressed, lethargic, confused, and dysphoric. This is colloquially termed a "crash" and may promote reuse of the stimulant.
Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. [1] The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine ), which function as both neurotransmitters and hormones .
Affect consciousness (or affect integration - a more generic term for the same phenomenon) [1] refers to an individual's ability to consciously perceive, tolerate, reflect upon, and express affects. [ 2 ] [ 3 ] These four abilities are operationalized as degrees of awareness, tolerance, emotional (nonverbal) expression , and conceptual (verbal ...
Embodied cognition is the concept suggesting that many features of cognition are shaped by the state and capacities of the organism. The cognitive features include a wide spectrum of cognitive functions, such as perception biases, memory recall, comprehension and high-level mental constructs (such as meaning attribution and categories) and performance on various cognitive tasks (reasoning or ...
