CCDS is correlated with brain changes including neuronal loss and _____ dilation.

Explanation:
When neurons are lost in CCDS, the brain tissue shrinks (cerebral atrophy). The ventricular system then enlarges to fill the space left behind, causing ventricular dilation. This pattern, known as hydrocephalus ex vacuo, is the classic way neuronal loss translates into a measurable dilation on imaging. So the best term to describe this change is ventricular dilation. The other options describe tissue loss or a single structure rather than the expansion of the ventricular CSF spaces.
