Abstract

Summary:Purpose:To evaluate the determinants of postoperative change in visual confrontation naming ability and the differential sensitivity of two common tests of confrontation naming. Methods:In a group of 99 patients undergoing lobectomy of the left, language‐dominant anterior temporal lobe, we examined naming ability using two measures: the 60 item Boston Naming Test (BNT), and the Visual Naming (VN) subtest of the Multilingual Aphasia Examination (MAE). ATL entailed resection of lateral temporal lobe followed by microsurgical complete removal of hippocampus. Language mapping was not performed. The status of the resected hippocampus was graded on a scale 0–4 of hippocampal sclerosis (HS). A dichotomous grouping HS‐ (grades 0 and 1, n = 34) and HS+ (grades 3 and 4, n = 61) was effected. Age at surgery, age of epilepsy onset, sex, extent of lateral temporal resection, Full‐Scale IQ (FSIQ), and preoperative naming scores were also examined as potential predictors of pre‐ versus postoperative naming change. Results:Preoperative BNT and VN scores were significantly worse for HS+ than for HS‐ (BNT, p c 0.05; VN, p = 0.001). Postoperatively, BNT and VN scores significantly declined for HS‐ as compared with HS+ patients (p c 0.001). For individual risk, the 90th centile of reliable change index (RCI) was used. By this criterion, of the total sample, 39% evidenced decline on the BNT and 17% evidenced decline on the VN. Logistic regression analysis with backward elimination showed HS to be the only predictor of decline in BNT and HS and sex to be the only predictors of VN decline. Males were more at risk than females. Age, age at onset, extent of lateral resection, preoperative scores, and FSIQ were not predictors. Using age at onset as a proxy for HS+/HS‐ we calculated probabilities for naming decline for given onset age. Conclusions:Both preoperative and postoperative change in naming ability are associated with the pathological status of the hippocampus. The potential interpretations and implications of these findings are discussed.

    From AAVrh.10-Mediated APOE2 Central Nervous System Gene Therapy for APOE4-Associated Alzheimer's Disease (2018) · cites this paper as [45]

    The Patients and Methods section describes subdural strip-electrode monitoring, while Implications for surgical management discusses the risk of naming decline after anterior temporal lobectomy. Neither compares intraparenchymal hippocampal routes or identifies one as having the greatest risk of an adverse event (searched: direct intraparenchymal hippocampal route; route, complications, and electrode implantation).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
