For example, increased [11C]‐PK11195 TSPO binding has been observed in the caudate, frontal, temporal, and parietal cortices in cognitively mild forms of dementia with Lewy body patients, when compared with those presenting moderate cognitive impairment (Nacastro et al., 2020; Surendranathan et al., 2018). The gene discussed is TSPO; the disease is Cognitive impairment.
