Ageing brings in several health problems. The brain also undergoes ageing. The ageing of the brain is accompanied by the decline in cognitive functions. One of the casualties in ageing is memory. A recent study in the US indicates that small amounts of nicotine can counter memory loss due to ageing. Nicotine also increased the attention span. It also helped aged individuals to process information faster and also consistently.
However, researchers caution against smoking. Too much of nicotine can make things worse. No one is sure of what amount of nicotine is safe and what amount would help prevent memory loss. More research is needed in this field.
