The Bender Gestalt: Use of clinical judgment versus recall scores in prediction of Huntington's disease.

Used Bender-Gestalt recall scores and clinical evaluation of Bender protocols to predict organicity in 2 comparisons in a total of 89 Ss: normals vs premorbids for Huntington's disease and normals vs Ss already affected with Huntington's disease (mean ages, 31 yrs for normals and premorbids and 38 yrs for Huntington's Ss). Mean Bender recall scores significantly discriminated between normals and premorbids. Chi-squares reflecting predictive accuracy were significant for both comparisons using the Bender recall score but were nonsignificant for the predictions by clinical evaluations. Hit rates for the recall score prediction, however, were not much better than those for the clinical evaluation method and were too low for diagnostic evaluation of individual cases.
