However, there is no further deterioration in memory, and some patients may even recover some of their memory capacity, reveals a thesis from the University of Gothenburg.
The group treated with medication was followed up after five years.
The surgically-treated patients were followed up after two and ten years. It emerged that these patients’ cognitive abilities did not decline between the two follow-ups.
“But verbal memory can be affected by surgery in the left temporal lobe. We also saw deterioration in these patients two years after surgery, but after ten years these memory problems had not worsened, although it did vary from person to person.”
The thesis also finds evidence of partial recovery of memory function in some patients.
Andersson-Roswall believes that it is important that patients with drug-resistant epilepsy are given an opportunity to be investigated for suitability for epilepsy surgery at an early stage of the disease, and that they are offered regular cognitive evaluations whatever the treatment.
“The results of our study can be used in investigations to advise on possible surgical treatment of those with drug-resistant epilepsy.”EPILEPSY
