A recent
study has shown that people suffering from type 2 diabetes and heart disease are at an increased risk of
dementia and other cognitive diseases.
Lead author Christina E. Hugenschmidt, PhD, an instructor of gerontology and geriatric medicine at Wake Forest Baptist, said the results from the Diabetes Heart Study-Mind (DHS-Mind) suggest that cardiovascular disease (CVD) plays an important role in the development of cognition problems, and these may take time before becoming clinically apparent. A report of the study appeared in Science Daily.
The research results, which appeared online, will also be followed by a print version in Journal of Diabetes and Its Complications.
"There has been a lot of research looking at the links between type 2 diabetes and increased risk for dementia, but this is the first study to look specifically at subclinical CVD and the role it plays," Hugenschmidt said. "Our research shows that CVD risk caused by diabetes even before it's at a clinically treatable level might be bad for your brain."
"The results imply that additional CVD factors, especially calcified plaque and vascular status, and not diabetes status alone, are major contributors to type 2 diabetes-related cognitive decline," Hugenschmidt said.

'People need to get less emotional about antibiotics'
People
need to talk about excessive use of antibiotics without getting emotional or
mixing politics into the discussion, Ada Yonath, who won the 2009 Nobel Prize in Chemistry, said.
"Perhaps we committed errors in using antibiotics for treating viral diseases ... but we learned that that does not work. We learned a bunch of things ... so it is incorrect to say we are abusing antibiotics," Yonath said.

Yonath is one of the scientists participating in the 3rd World Summit on Evolution on Ecuador's Galapagos Islands.
The summit, which ends Thursday, is taking place in Puerto Baquerizo Moreno, where leading scientists are discussing evolution, genomics, microorganisms and diseases, among other topics.
Yonath said antibiotics were extremely useful, but she criticized the "political" use of the issue.
The use of antibiotics to fight bacterial infections has allowed average life expectancies to rise from 40 or 50 years to double that in just a few decades, Yonath said.
