Concerns are expressed in the West over the increasing tendency on the part of normal people to take dementia and ADHD drugs to improve their memory. It may not be safe, it is apprehended.
For potential side-effects include heart attacks, blurred vision, pain, numbness and seizures.
Drugs meant for treatment of dementia or Attention Deficit Hyperactivity Disorder (ADHD) generally work by increasing levels of certain brain chemicals.
The drug Ritalin, for instance, boosts a hormone called noradrenaline.
This helps hyperactive children to focus on one thing at a time - but when used in otherwise healthy adults, it makes them feel more alert and full of energy.
Only last summer there were reports that British parents were buying Ritalin on the internet for their healthy children to boost exam results. As many as 10 per cent of students at American universities are thought to be using Ritalin and Adderall (another ADHD drug) to improve their performance, reports The Daily Mail from the UK.
And it's not just students who are getting chemical help. Another prescription drug, Provigil, is widely used by businessmen and other professionals to overcome the effects of jet-lag by making them feel focused and alert even when they haven't slept. Users also report their performance improves as well. The drug is officially licensed to treat narcolepsy,a neurological condition most characterized by Excessive Daytime Sleepiness (EDS).
psychology professor wrote an article in the science journal Nature, calling for a debate on the use of these 'cognitive-enhancing' drugs. 'We've done informal research that shows not only students, but also senior academics, are using smart drugs to improve their performance,' says the author and professor of clinical neuropsychology, Barbara Sahakian.
