Estimated general cognitive impairment across the life span in schizophrenia, psychotic bipolar disorder, and psychotic depression. Effect size estimates based on studies presented in this review (e.g. Mollon & Reichenberg, 2017; Seidman et al., 2016; Heinrichs & Zakzanis, 1998; Mesholam-Gately et al., 2009; Daban et al., 2006; Hill et al., 2013; Martinez-Aran et al., 2004; Schatzberg et al., 2000). No data is currently available for premorbid or ultra-high risk psychotic depression.
Childhood+ = children who develop disorder; UHR+ = ultra high risk individuals who develop disorder.
