Prevention and early behavioral intervention are of paramount importance given the lack of approved drug therapies for these patients.A drug that produces transient increases in locomotor activity in animals and is used as a pharmacotherapy to treat behavioral disorders such as ADD and ADHD. Acute withdrawal from psychostimulants produces major elevations in brain reward thresholds that may have a critical role in driving escalation to dependence. Despite natural versus synthetic sources and differences based on chemical structures, all of these drugs function primarily as indirect dopamine agonists in central nervous system (CNS) synapses, which leads to their stimulant effects in the human and laboratory animals (Some pharmacologists would include among the psychostimulants the xanthines such as caffeine that are primarily adenosine antagonists, and nicotine, which is primarily an agonist at nicotinic acetylcholine receptors. In susceptible individuals, chronic use can cause addiction leading to devastating physical, psychological, and social health consequences.

Psychostimulants are frequently used in combination with other substances. Stimulants are dangerous drugs that are commonly abused by individuals looking to stay alert and focused, lose weight, stay awake, and get high. Since psychostimulants have no effect on seizure threshold, they can be used in patients with a history of seizures. Psychostimulants (mainly methylphenidate) have traditionally been associated with the appearance of tics due to the increased dopamine activity caused by stimulants.A drug that indirectly mimics “sympathin,” which was the original term for norepinephrine (also known as noradrenaline). Today we're going to talk about psychostimulants, some of the most important drugs in the addiction field. This chapter describes psychostimulant use, abuse, and addiction, and delves into the physiological, behavioral, and neuroscientific mechanisms by which the psychostimulant effects occur.Psychostimulant drugs have a long history of abuse and dependence with episodic collective amnesia associated with excessive use.

The chapter describes the mechanism of action of psychomotor stimulant drugs at the behavioral, neuropharmacological, and molecular levels that have important implications for understanding the neurobiology of addiction to psychostimulants. An increasing number of works over the past decade have demonstrated the important role of epigenetic regulatory events in mediating the lasting effects of drugs of abuse (including psychostimulants, such as cocaine and amphetamine) in animal models of drug addiction. psychiatrists, neurologists, respiratory & sleep physicians, palliative care physicians) may apply for authorisation to prescribe psychostimulant medication for a person aged 18 years or over by submitting an Application for Authority to Prescribe a Schedule 8 Drug – Psychostimulant.
