Dementia diagnosis rate on the decline, research indicates
The rate of diagnosis for dementia appears to be declining over the short and long term, according to three studies being presented at the Alzheimer's Association International Conference. One study found the diagnosis rate is down 44% from the late 1970s in the U.S., and a second study showed a similar decline based on data from the U.S., England, Sweden and the Netherlands. The greatest gains were seen among people in their 60s. The third study found the risk of dementia declined in Germany from 2004 to 2007. HealthDay News
Sleep disturbance tied to higher dementia risk in veterans study
An analysis involving 192,266 veterans ages 55 years and older found that those suffering from sleep apnea, insomnia and other forms of sleep disturbance were 30% more likely to develop dementia. The risk of developing dementia was 80% higher among veterans who also had post-traumatic stress disorder. The findings were presented at the Alzheimer's Association International Conference.

Study: "Nonvisit communications" do not reduce office visits
A study of 18,486 diabetic adults published in the Annals of Family Medicine found that greater patient use of secure electronic messaging and telephone calls only slightly reduced the number of in-person visits, however an analysis that adjusted for factors such as morbidity indicated greater use of such communications was linked to increased office visits. It is logical that patients who had more contact with clinicians "could be more engaged in their health," said study author David Liss. Medscape (free registration)
