Impaired reproductive function is thought to frequently affect women with epilepsy, mainly when seizures originate in the temporal lobe. In this study, we evaluated menstrual cycle features and assessed ovulation by determining luteal progesterone (Pg) levels in 101 consecutive women with epilepsy (36 with idiopathic generalized epilepsy -IGE; 65 with partial epilepsy -PE), aged between 16 and 50 years, treated with various antiepileptic drugs (AED). PE originated in the temporal lobe (TLE) in 40 subjects, in the frontal lobe in 13, in the parietal lobe in 2, while the origin of focal seizures remained undetermined in 10 patients. In all patients, menstrual and reproductive history, body mass index, hair distribution and hormonal pattern were assessed. Suprapubic ovary ultrasound (US) examination was carried out in 83 patients (28 with IGE, 55 with PE). Three patients with IGE and one with PE were amenorrheic. Oligomenorrhea occurred in 16 patients, polymenorrhea in 2. Changes in menstrual cyclicity were independent from epilepsy type (19.4% in IGE; 23.1% in PE) and from origin of focal discharges (22.5% of patients with TLE; 20.0% with origin in other brain areas). Luteal Pg levels remained below 2 ng/ml in 30 patients independently of epilepsy type. Corpus luteum dysfunction was combined with hyperandrogenism in 15 of these patients. In the other cases different alterations of hypothalamus-pituitary-ovary axis were observed. Valproic acid blunted luteal Pg surge more frequently than other AED. Polycystic ovaries (PCO) were observed in 14 (16.9%) patients (21.0% with IGE: 14.5% with PE). These prevalences are not higher than those reported in the general population. Among PE patients, PCO was found in 1 case with undetermined focal origin and in 7 TLE cases, who also had ovary volume significantly larger than patients with seizures originating from the frontal or parietal lobe. Epileptic women exhibited an increased occurrence of multifollicular ovaries (MFO) found in 12 cases (14.4% vs 5% in the general population). However, no defined hormonal or clinical pictures were associated with this US alteration in most patients. These findings reappraise the impact of ovary alterations in women mainly affected by mild to moderate epilepsy, on differing AED regimens, with the exception of more frequent ovulatory dysfunction and PCO occurrence in patients taking VPA.

Summary:Purpose: The aim of this study was to evaluate the rate and features of obstructive sleep apnea (OSA) in adult epilepsy patients.Methods: Two hundred eighty-three adult epilepsy patients (137 men; mean age, 33 years; range, 18-70 years) were prospectively screened for OSA by means of a structured interview. Those in whom OSA was clinically suspected were monitored for a full night by using a portable device (Polymesam), and OSA was diagnosed when they had an Apnea/Hypopnea Index greater than five.Results: Coexistence of OSA with epilepsy was found in 10.2% (15.4% of the male and 5.4% of the female) epilepsy patients investigated. The OSA was mild in 66.6%, moderate in 22.2%, and severe in 11.1% of the cases. The "epilepsy + OSA" patients were older, heavier, more frequently male, and sleepier (p < 0.05) than those with "epilepsy only." Furthermore, they experienced their first seizure at an older age (p < 0.05).Conclusions: Systematic investigation reveals that OSA is frequent in epilepsy patients. The major risk factors for OSA in our epilepsy patients were the same as those typically found in the general population. Of the epilepsy-related factors, older age at onset of seizures appears to be significantly related to comorbidity with OSA (p < 0.05). The presence in epilepsy patients of these features should alert the clinician to the possibility of an underlying OSA.

The aim of this study was twofold: 1 - to identify a psychological profile of patients with psychogenic nonepileptic seizures (PNESs) that is possibly distinct from that of subjects affected by epileptic seizures (ESs) alone; 2 - to detect the possible differences between the clinical features and psychological profile of patients affected by PNESs alone and those of subjects in whom PNESs are associated with epileptic seizures (ES/PNES patients). We assessed the psychological profiles of 2 different groups of subjects. The first group was of 38 patients who had all developed PNESs after epileptic seizures (ES\PNES, group 1). The second group was of 31 patients with PNESs alone (PNES, group 2). We compared the psychological findings of each of these 2 groups with those of 2 control groups, composed of patients who matched groups 1 and 2 for sex, age, and educational level, but who were affected only by ESs (groups 1C and 2C). Finally, we considered possible differences between the ictal symptoms and signs of PNESs occurring in ES/PNES and in PNES patients. Both the ES/PNES group and the PNES group revealed higher percentages of Somatoform Disorders and Cluster B Personality Disorders (DSM-III-R diagnoses) than the ES patients in the control groups. The scores obtained on the Psychophysiological Distress Scale of the Cognitive Behavioural Assessment Battery (CBA) followed the same pattern. Among PNES ictal phenomena, autonomic symptoms and signs were significantly more frequent in the PNES than in the ES/PNES group. The occurrence of PNESs mimicking generalised tonic-clonic ESs (GTC-PNESs) was significantly associated with a low academic level. The results of this study suggest that the patients with PNESs alone and those affected by PNESs and ESs share the same psychological profile, which is different from that of patients with ESs alone. However, some differences between ES/PNES and PNES patients were found in the clinical semiology of their PNESs. Our findings could have implications for the diagnosis and for the treatment of patients with PNESs.

Male epileptic patients frequently complain of sexual dysfunction, particularly impotence and loss of libido. Epilepsy itself, antiepileptic drugs (AEDs), and psychosocial factors are believed to contribute to impaired sexuality. We studied luteinizing hormone (LH) pulsatile secretion, gonadotropin, and prolactin (PRL) responses to LH-releasing hormone (LHRH) and thyrotropin-releasing hormone (TRH) in 37 adult male epileptic patients receiving AED monotherapy who were seizure-free and had normal EEGs. Sexuality was assessed by psychological interview. Impotence was diagnosed in 8 patients (in 2 combined with loss of sexual desire). The occurrence of hyposexuality (approximately 20%) was independent of epilepsy syndrome or AED. No change in total testosterone (T) level was observed. Free T (fT) and dihydrotestosterone (DHT) levels were lower and sex hormone binding globulin (SHBG) levels were higher in epileptic subjects than in healthy controls, but a statistically significant difference was not observed between hypo- and normosexual patients. In impotent epileptic patients, estradiol (E2) levels were significantly increased as compared with those of patients with preserved sexuality and of healthy controls. The unbalanced relation between androgen and E2 levels was emphasized by decreased T/E2, fT/E2, and DHT/E2 ratios obtained in hyposexual epileptic patients. In this group, LHRH induced blunted LH peaks. No changes were noted in LH pulsatility features. These findings of higher E2 levels and of decreased LH response to LHRH administration in some epileptic patients with impaired sexuality, may suggest they have subclinical hypogonadotropic hypogonadism.

Our data suggest that an early HR decrease is more probable in temporal lobe seizures than in seizures of other origin. An accurate HR measurement, focused on discharge onset, may provide both a reliable way of evaluating the possible effect of partial seizures on HR and valuable information about the cerebral sites involved in the control of cardiac rhythm.

The efficacy and tolerability of vigabatrin (gamma-vinyl GABA, GVG), given as add-on therapy to 23 adult outpatients with severe drug-resistant epilepsy (17 with partial seizures), were studied using a double-blind, placebo-controlled, crossover design. The study consisted of two 7-week periods during which vigabatrin and placebo were administered in random sequence. Dosage was 1.0 g twice daily for patients weighing less than or equal to 65 kg and 1.5 g twice daily for patients weighing greater than 65 kg. Three patients were dropped from the study, two for reasons unrelated to treatment and one because of the appearance of vertigo, headache, dysarthria, and ataxia, which subsided rapidly when vigabatrin was stopped (3 g daily). Sixteen of the 20 patients available for analysis showed a decrease in the total number of seizures as compared with the placebo period. Of these, 12 showed a greater than 50% reduction in seizure frequency and 4 of the 12 showed a greater than 75% reduction. Both the total number of seizures and the number of partial seizures were significantly reduced by vigabatrin (p less than 0.01). Only in the patient who dropped out were severe adverse effects seen. The most frequently reported unwanted effect was mild drowsiness, which developed in seven patients on vigabatrin and in one on placebo. Positive effects, however, were also seen with six patients who reported an improved sense of well-being while receiving vigabatrin as compared with only 1 during the placebo period. No consistent changes in electrocardiogram (ECG), electroencephalogram (EEG), and visual-, auditory-, and somatosensory-evoked potentials were seen during the study.(ABSTRACT TRUNCATED AT 250 WORDS)

SUMMARY Subjective sleep quality and its related factors were investigated in 869 (530 F, 339 M) 17-year-old adolescents, who were selected from the pupils of state-run secondary schools in the city of Pavia in the north west of Italy. The study was conducted cross sectionally, and it consisted of a questionnaire based survey. One hundred and fortytwo subjects (16.5% of the whole sample, 19% of the females and 11.7% of the males) met the criteria chosen for definition as poor sleepers (namely, a complaint of 'non restorative nocturnal sleep', 'often' or 'always' over the previous 12 mo). A significant association was found between chronic poor sleep and (1) gender (female) (2) emotional factors, such as worries, anxiety and depression (3) poor sleep hygiene (4) arousal related parasomnia. Only 4% of poor sleepers took sleep promoting drugs (including benzodiazepines, homeopathic products and other medications), generally without seeking medical advice. adolescence, poor sleep INTRODUCTION schools in the city of Pavia, which is a medium sized city of 80000 inhabitants in the north west of Italy.
