One in ten patients is at risk of having new post-traumatic stress disorder (PTSD) related to their ICU experience up to a year post-discharge. This was the finding from a multicenter, prospective cohort research study of veterans and civilians.

Protein deposits in cells, such as those associated with diseases like Parkinson's and Alzheimer's, can also be beneficial -- at least for yeast cells, as biochemists have discovered. The researchers found a new form of age-associated deposits in these cells, and they are now asking us to rethink our views on aging and dementia.

Researchers have figured out how a developmental disease called microcephaly produces a much smaller brain than normal: Some brain stem cells are simply too slow as they proceed through the neuron production process. The findings provide not only a new mechanistic explanation for microcephaly, but could also enhance understanding of autism or other neurodevelopmental disorders thought to arise from disruptions in the proper balance of neurons in the brain.
