Visual search patterns in semantic dementia show paradoxical facilitation of binding processes

▶ Patients with Alzheimer's disease show visual attention deficits. ▶ We tested visual search performance of patients with other forms of dementia. ▶ We found that semantic dementia patients may show enhanced conjunction search. ▶ Search performance correlated with gray matter volume in fronto-parietal network. ▶ Implications for the paradoxical facilitation of visual talent are discussed.
