What percentage of Frontotemporal dementia cases show ubiquitin immunoreactive inclusions?

Ubiquitin-positive inclusions are a common finding in frontotemporal dementia and reflect the FTLD-U subgroup, which is often linked to TDP-43 pathology. Neuropathology studies have shown that about half of FTLD cases exhibit these ubiquitin-immunoreactive inclusions, making roughly 50% the best estimate. This explains why the mid-range option is correct: ubiquitin inclusions are a frequent but not universal feature in FTLD. The other percentages are not as consistent with the broader neuropathology literature, where the finding is common but not present in all cases.
