Memory Lapses




        Scientists have found a link between genetics and the common short-term memory loss. Everyone has memory lapses, but scientists found some had lapses more often than others. Short term memory and action are mainly controlled by the DRD2 gene. The gene directs action and if there is a mishap then a memory lapse may occur. DRD2 comes in 2 forms, both with single letter difference in their coding from each other. Scientists noticed that when taking samples of 500 men and women’s saliva they found one-fourth had the Cytosine variant, while the other three-fourths carried the Thymine variant. They asked the subjects to keep a log of how often these lapses occur over a period of time, and the results showed that those with the Thymine variant had a clear lead in number of incidents. They found that the increased chance of memory lapses found in the Thymine variant subjects followed suit with several other known experiments and their findings. To read other causes of memory loss, go here.

        I believe this article was solid in its foundation and findings. The scientists mention that when comparing data results with other experiments in the same field the findings matched to a great extent. I think that when experiments have results this solid it makes for a great source for further testing and progress in the field.

  1. This is pretty cool. It's interesting to see that the Thymine variants have more short-term lapses than Cytosine variants. I wonder why that is; finding out why would be fascinating.
