Cognitive enhancers are medication, supplements, vitamin, or drugs to improve the cognitive level of a person. Cognitive includes memory, mental alertness, concentration and to a certain extent boosting the energy levels as well. These medications aren't to improve the intelligence but it aids in masking fatigue, procrastination, and boredom. Cognitive enhancers are also known as nootropics. Some of the examples of cognitive enhancers are Modafinil, Armodafinil, Methylphenidate, Atomoxetine, and Donepezil which are prescribed for conditions such as ADHD and Alzheimer's disease. However, some of these drugs when used in the long term can cause side effects such as stomach ulcers, rapid heartbeat and anxiety. Popular supplements of cognitive enhancers such as vitamins B, fish oil, Gingko Biloba and ginseng have been proved to have neutral effects on normal person based on current trials. However, there are more ongoing researches conducted to see their long terms effect on the brain of healthy and diseases people.
