Caffeine associated sleep disturbance

This month's Sleep Journal has an article about genetic influences on caffeine's ability to produce sleep disturbances. Dr. Byrne and others surveyed over two thousand individuals for caffeine's propensity to cause sleep disturbance. The study authors then analyzed millions of gene fragments from the study participants and discovered that several genes are thought to influence caffeine induced insomnia. This is interesting because it could help in our assessment of the etiology of insomnia and may improve our treatments.
