People who smoke or have diabetes may be at increased risk of calcifications in a region of the brain crucial to memory, according to a new study published online in the journal Radiology.
Dementia is a major public health problem that affects tens of millions of people worldwide. One focus of dementia research has been the hippocampus, a brain structure important for both short- and long-term memory storage. Alzheimer's disease, the most common type of dementia, is associated with atrophy of the hippocampus.
Researchers have hypothesized that abnormal buildups of calcium, or calcifications, in the hippocampus may be related to vascular problems that could contribute to hippocampal atrophy and subsequent cognitive deterioration. However, published research on the association between hippocampal calcification and cognitive impairment is limited.
"We know that calcifications in the hippocampus are common, especially with increasing age," said the study's lead author, Esther J.M. de Brouwer, M.D., a geriatrician at the University Medical Center in Utrecht, the Netherlands. "However, we did not know if calcifications in the hippocampus related to cognitive function."
Advances in imaging have provided opportunities to explore the role of hippocampal calcifications in dementia. The development of multiplanar brain CT scans has enabled better distinction between hippocampal calcifications and calcifications in nearby brain structures like the choroid plexus.
"A multiplanar CT scan makes it possible to see the hippocampus in different anatomical planes; for example, from top to bottom, right to left and front to back," Dr. de Brouwer said. "Before multiplanar CT scans, hippocampal calcifications were often mistaken for choroid plexus calcifications. So with multiplanar CT scans, hippocampal calcifications are better distinguished from calcifications in other areas."
[...] The researchers plan to carry out additional studies in different groups of people to better understand possible links between these calcifications and cognitive problems.

Well it's not like we need an additional reason to shit on smoking.
The story is about imaging, and that first paragraph of TFS seems to be just thrown in there, without any elaboration. Then it made it into the title of the post.
The story would have been fine and interesting without EITHER the smoking or diabetes angle. Or maybe I just gotta read TFA.
No, you are mistaken. I've always had this sig.

There's no need to go acting crazy now.
My rights don't end where your fear begins.
