Tau accumulations in the brains of woodpeckers

Dr. Peter Cummings makes another appearance on the blog, this time as senior author on a paper entitled: Tau Accumulations in the Brains of Woodpeckers. Eight of ten woodpeckers examined showed cerebral tau accumulations, whereas no control brains (red-winged blackbirds) were positive.This is significant in that there has been some research interest in developing football helmets based on the protective design that has evolved to protect the brains of woodpeckers.But maybe the relatively short life of the woodpecker (average less than 10 years) precludes the need to this protective adaptation. Thanks to Dr. Mark Cohen for alerting me to this study.

Las Vegas gunman had unusually high burden of corpora amylacea, but no other significant findings, at autopsy

The New York Times reports that brain autopsy results on Las Vegas gunman Stephen Paddock show that he "had not had a stroke, brain tumor or a number of other neurological disorders that might have helped explain his actions". 

Paddock, 64-years-old, did have an unusually high burden of corpora amylacea, the significance of which is not known.

In the article, Stanford neuropathologist Hannes Vogel commented on the corpora amylacea as follows: “Most people would have them at that age, but not in that profusion,” Dr. Vogel said. “It’s a striking exaggeration of an age-related finding.”

I put up a post a few months ago about Dr. Vogel receiving the brain for examination.

TBI Linked to Increased Dementia Risk Over Several Years

The following is adapted from a recent post on
Traumatic brain injury (TBI) is associated with persistently increased risk of dementia, according to a study published online Jan. 30 in PLOS Medicine.

Anna Nordström, M.D., Ph.D., and Peter Nordström, M.D., Ph.D., both from Umeå University in Sweden, tracked dementia and TBI diagnoses among all 3,329,360 individuals in Sweden

The correlation was strongest in the first year after TBI (odds ratio, 3.52) and persisted at >30 years (odds ratio, 1.25). A weaker association with dementia was seen for single mild TBI versus more severe TBI or multiple TBIs (odds ratios, 1.63 versus 2.06 and 2.81, respectively). Among sibling pairs with discordant TBI status, TBI correlated with increased risk of dementia diagnosis (odds ratio, 1.89).

"The risk of dementia diagnosis decreased over time after TBI, but it was still evident >30 years after the trauma," the authors write.
