Stimulant psychosis is a mental disorder characterized by psychotic symptoms (such as hallucinations, paranoid ideation, delusions, disorganized thinking, grossly disorganized behaviour). It involves and typically occurs following an overdose or several day binge on psychostimulants , [ 1 ] although it can occur in the course of stimulant ...
A systematic review of cardiovascular effects of prescription stimulants found no association in children, but found a correlation between prescription stimulant use and ischemic heart attacks. [16] A review over a four-year period found that there were few negative effects of stimulant treatment, but stressed the need for longer-term studies. [17]
A psychoactive drug, mind-altering drug, or consciousness-altering drug is a chemical substance that changes brain function and results in alterations in perception, mood, consciousness, cognition, or behavior. [1] The term psychotropic drug is often used interchangeably, while some sources present narrower definitions.
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.
Amphetamine use is rising among students due to the ability to easily access prescribed stimulants like Adderall. [5] Also, in case of chronic use, vegetative disorders soon occur such as bouts of sweating, trouble sleeping , tremor , ataxia and diarrhea ; the degradation of the personality takes place relatively slowly.
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 .
Drugs are researched for their physiochemical properties, physical side effects, and psychological side effects. Researchers in psychopharmacology study a variety of different psychoactive substances, including alcohol, cannabinoids, club drugs , psychedelics, opiates, nicotine , caffeine , psychomotor stimulants , inhalants , and anabolic ...
Alcohol increases the effect of the neurotransmitter GABA (gamma-Aminobutyric acid) in the brain. GABA causes slow actions and inaudible verbal communication that often occur in alcoholics. [30] Alcohol also decreases the excitatory neurotransmitter glutamate. Suppressing this stimulant results in a similar type of physiological slowdown.
