Methylphenidate and its effects on the human body

Open in a separate window Although most of the reported positive effects of such drugs have been modest in magnitude overall and are highly variable across individuals, they have had an enormous impact, stimulating interest in cognitive enhancement not only for patients with brain disorders, but also for healthy individuals. Compounds such as methylphenidate and modafinil are used by students in pursuit of better grades, military personnel who need to remain awake for long missions, elderly individuals afraid of cognitive decline and even university academics keen to maintain their performance [14—17]. Here we focus on what aspects of cognition are enhanced, the magnitude of these effects and possible mechanisms underlying variations in response across individuals. Our aim is to highlight key common themes across studies of clinical populations and healthy individuals, using examples that highlight these principles.

The abuse of this drug in larger doses, especially through injection or snorting, puts an even greater strain on the body. The stress on the heart can be fatal. Take the case of a teenager—a long-term user of Ritalin—who collapsed one day while skateboarding. Dead of a heart attack.

These solid materials block the small blood vessels when injected into the blood stream, causing serious damage to the lungs and to the eyes. Aside from the physical impact, there are also severe emotional conditions caused by even short-term use of this drug.

Hallucinations and psychotic behavior are not uncommon. A researcher in Texas found that Ritalin use may heighten the danger of cancer. This study found every one of a dozen children treated with methylphenidate experienced genetic abnormalities associated with an increased risk of cancer.

In addition, dopamine can have very different effects at different brain regions, even within different regions of the human basal ganglia. Its release can also be modulated in a highly specific regional manner by other neurotransmitters, such as glutamate within the nucleus accumbens [32].

This is because ethylphenidate has a very limited history of human usage. Methylphenidate: efficacy and adverse effects.

Methylphenidate and its effects on the human body

Systematic review has shown that the expected effects of methylphenidate exceed its actual effects, as demonstrated in single or double-blind randomised controlled trials.

A single dose of methylphenidate has been shown to benefit memory in healthy subjects, as well as increase subjective ratings for interest, excitement and motivation in a .

Molecules that can be superimposed on their mirror images are achiral (not chiral). Chirality is a property of matter found throughout biological systems, from the basic building blocks of life such as amino acids, carbohydrates, and lipids to the layout of the human body.
