چکیده

AIM OF THE STUDY was to provide new data about the evolution of neuropsychological findings in patients with lesional frontal lobe epilepsy (FLE) operated on with lesion excision. PATIENTS AND METHODS Twelve patients with lesional FLE underwent full clinical examination including neurological, neuropsychological and developmental assessments, high-resolution magnetic resonance imaging (MRI), ictal and interictal prolonged EEG monitoring and evaluation of seizure semeiology before and after surgery. The mean follow-up duration was 2 years and 10 months (range=14 months-7 years). Another group of lesional temporal lobe epilepsy, matched for the age at surgery and side of surgery, was likewise studied in order to compare neuropsychological patterns and to try to find out specific features in frontal lobe epilepsy evolution. RESULTS All patients resulted seizure free at outcome except one belonging to Engel's class II. Before surgery general intelligence was similar in FLE as well as in TLE group. Executive functions and motor coordination were frequently affected in FLE whereas patients with TLE often presented with deficits in naming, visual memory and visuo-spatial attention. After surgery there was a frequent decline of IQ in FLE group together with a slight deterioration, especially of executive functions in some patients. An improvement of behaviour was often observed in both groups. CONCLUSIONS As already reported in literature, neuropsychological pre-surgical data confirms the involvement of attention and executive functions in lesional FLE. No significant neuropsychological improvement was produced by surgery that determined in some cases a slight decline of general intelligence and specific frontal abilities. Yet, generally behaviour improved and seizures were controlled.

Effects of Surgical Side and Site on Mood and Behavior Outcome in Children with Pharmacoresistant Epilepsy

Children with epilepsy have a high rate of mood and behavior problems; yet few studies consider the emotional and behavioral impact of surgery. No study to date has been sufficiently powered to investigate effects of both side (left/right) and site (temporal/frontal) of surgery. One hundred patients (aged 6-16) and their families completed measures of depression, anxiety, and behavioral functio...

Deficits in executive functions and motor coordination in children with frontal lobe epilepsy.

Frontal lobe dysfunction in adults has been associated with impairments of planning abilities, working memory, impulse control, attention and certain aspects of motor coordination. However, very few studies have attempted to assess these functions in children suffering from frontal lobe epilepsy. The aim of the present study was to determine whether some or all of the components of the frontal ...

Epilepsy surgery in bifrontal injury from prior craniopharyngioma resections☆☆☆

Epilepsy surgery in frontal lobe epilepsy (FLE) has less favorable seizure-free outcomes than temporal lobe epilepsies. Possible contributing factors include fast propagation patterns and large clinically silent areas which are characteristics of the frontal lobes. Bilateral frontal lobe abnormalities on MRI are another relative contraindication to epilepsy surgery. For example, bilateral encep...

Behavioral abnormalities have been noted in specific epilepsy syndromes involving the frontal lobe. Epilepsies that involve the frontal lobe, such as frontal lobe epilepsy (FLE), atypical evolution of benign childhood epilepsy with centrotemporal spikes (BCECTS), and epilepsy with continuous spike-waves during slow sleep (CSWS), are characterized by impairment of neuropsychological abilities, f...
