[Neuropsychological profile of Mexican paediatric patients with pharmacoresistant focal epilepsy].

INTRODUCTION

At least 20% of paediatric patients with epilepsy present resistance to multiple anti-crisis drugs in trials, which has a negative impact on their neuropsychological state, quality of life and prognosis; it is therefore necessary to document their neuropsychological profile in order to improve the clinical approach to them.

AIMS

To describe the neuropsychological profile (cognitive, academic, behavioural, emotional, adaptive, sleep disturbances and quality of life) of paediatric patients with drug-resistant focal epilepsy in the frontal, temporal and occipital lobes, and to compare performance between patients with frontal and temporal foci, and to assess the link between the duration of the condition, the frequency of seizures and the amount of anti-crisis drugs and the neuropsychological profile.

PATIENTS AND METHODS

The neuropsychological profile of 19 paediatric patients with a diagnosis of pharmacoresistant epilepsy with a mean age of 10.89 years was evaluated.

RESULTS

57.9% of the 19 patients were men. 63.2% presented frontal focus; 26.3% presented temporal focus; and 10.5% presented occipital focus. Deficiencies in attention, comprehension, verbal memory, working memory and processing speed, in addition to adaptive difficulties were observed. When the patients with frontal and temporal focus were compared, the former were found to present greater deficits in planning, while the patients with temporal focus presented more severe symptoms of anxiety. Patients with a longer disease duration were found to present greater impairment to their intelligence quotient and adaptive behavioural skills.

CONCLUSIONS

Pharmacoresistant epilepsy in paediatric patients affects intelligence quotient and adaptive skills, as well as attention, memory and executive functions, and neuropsychological intervention programmes must therefore be implemented to improve these patients' quality of life.
