GABRQ and Alzheimer disease: We quantified VENs and GABRQ‐immunopositive neurons in the anterior cingulate cortex (ACC) in FTD with underlying TDP43 (FTLD‐TDP) (n = 34), tau (FTLD‐tau) (n = 24) or FUS (FTLD‐FUS) (n = 8) pathology, neurologically healthy controls (n = 12) and Alzheimer's disease (AD) (n = 7).
