Take Nootropics to Enhance Intelligence and Memory

Nootropics are substances which are used to increase or enhance human cognition under normal circumstances. Since nootropic drugs are knwn to increase brain power and enhance memory among humans, they are widely and popularly known as smart drugs among the masses. The term nootropic was first coined by a Romanian Dr. Corneliu E. Giurgea in 1972 and is derived from the Greek words which mean'acting on the mind'.

Also known and marketed as brain steroids, memory enhancers, and cognitive enhancers or intelligence boosters, these nootropics are low toxicity drugs, supplements, nutraceuticals, and functional foods which are taken mostly over the counter by people to increase energy, enhance cognition, improve memory, sharp
en vigilance, increase motivation, expand learning capacity and raise concentration.

Though the efficacy of most of the nootropic drugs has been established, exact methodoly of action for these nootropic substances is not yet clear among the scientists or medical professionals. As per the experts, nootropic drugs or supplements act on the mind by increasing oxygen and glucose uptake in the brain cells along with stimulating the nerve growth. Doing this, nootropic substances tend to alter or increase the availability of neurochemicals or neurotransmitters such as dopamine, serotonin etc. to the brain.Though most nootropics are non toxic supplements generally made from plants and herbs to be used as dietary supplements among otherwise healthy individuals, there are certain nootropics which act as medicines and are thus used to treat various mind related disorders and conditions such as alzhiemer's disease, senile dementia, depression and parkinson's disease among the elderly while treating mental retardation, dyslexia etc. among the children.

Among a vast variety of nootropic drugs and supplements available today, piracetam belonging to the racetam class of nootropics was the first drug discovered to be effective and helpful in treating memory loss, age related memory decline and lack of concentration among the elderly. It was found that piracetam as compared to other memory enhancers had a beneficial effect upon the brain's Corpus Callosum, which connects the two hemispheres of the brain responsible for reasoning and creativity.

Nootropil thus act as wonderful brain power supplements or medicines which effectively work to reduce damage done to the brain cells, repair brain cells and nerves, prevent further damage caused due to free radicals and enhance overall cognition and energy to a greater level.

The most popular nootropic drugs available in the market today are Racetams such as piracetam, pramiracetam, aniracetam, and stimulants or Eugeroics like adrafinil, modifinil etc. Due to their no to low toxicity these drugs are generally devoid of side effects or carry very few and rare mild adverse effects such as headaches, nausea and insomnia.
