Remediation of a Naming Deficit Following Left Temporal Lobe Epilepsy Surgery

Dysnomia is associated with temporal lobe epilepsy and may include a deficit in recalling the names of familiar people. The deficit can worsen following surgery to relieve refractory seizures. The following is a case report comparing implicit (errorless learning) and explicit (rote rehearsal) approaches to retraining face-name associations in a 52-year-old woman who was status post-amygdalo-hippocampectomy for refractory complex partial seizures. Although both approaches initially improved performance above baseline, only errorless learning resulted in stable gains during a 10-min delay and at 1-week follow-up. Initial improvements in naming with rote rehearsal were not maintained even during the 10-min delay. In patients with severe memory impairment and dysnomia, errorless learning may offer a viable rehabilitation strategy for improving naming performance.
