In 2009, researchers led by Anders Fjell at the University of Oslo, Norway, found that the cortex, known to shrink in patients with mild cognitive impairment and Alzheimer's disease, also diminished in older healthy people within as little as one year. The ventricles are spaces located deep inside the brain which contain CSF. Others were cautious to point out that AD may still be partly to blame for the shrinkage. 1992 Oct;149(10):1324-34. doi: 10.1176/ajp.149.10.1324.
