Anomia prehabilitation in temporal lobe epilepsy surgery: A pilot study

An emerging approach in surgery is to propose prehabilitation programs to strengthen the patient's functional abilities before surgical interventions, thus helping them cope better with its consequences. In drug-resistant language-dominant temporal lobe epilepsy (LdTLE), surgical treatment carries a risk of increasing cognitive deficits, notably word-finding difficulties (anomia) and verbal memory difficulties that negatively impact personal, social, and occupational activities. In this study, we invited 15 LdTLE patients to enroll in a speech and language prehabilitation program adapted to the specifics of their difficulties, organized daily during the preoperative period.

Naming performance (for trained and untrained words) was studied twice before prehabilitation, during prehabilitation, and 1 week and 6 months after surgery. Results were analyzed using a generalized linear mixed effects model.

We found a significant effect of prehabilitation on trained items before surgery. Postoperatively, trained items showed a slight and nonsignificant performance increase compared to baseline, whereas untrained items showed a significant decline in the same comparison.

We conclude that trained words were better protected from postsurgical decline than untrained words. Our research can contribute to patient support during surgical decision-making; ultimately, prehabilitation might be considered as part of individualized care. These encouraging results lay the groundwork for more detailed or powerful examinations of the protective effect of prehabilitation on language skills.
