A study has recommended that common over-the-counter medicines for
colds and flus should be avoided by older people after a link was found
between the medicines and a reduction in brain function.
According to scientists at Indiana University School of Medicine the study found that two of the key ingredients promethazine and diphenhydramine found in these medicines were causing reduced brain function and smaller brains.
The medicines affected include cold and flu tablets, medicines for hay fever and even anti-heartburn pills.
The study found that the two drugs were blocking the chemical acetylcholine which is used in the transmission of electrical signals within the brain.
