In recent years, a differentiation has been made between two syndromes that are characterized by brief abnormal paroxysmal movements occurring principally at night: 1, hypnogenic paroxysmal dystonia (HPD), sometimes considered a particular form of dystonia similar to paroxysmal kinesigenic choreoathetosis, and 2, mesiofrontal epilepsy. Whether HPD is a distinct syndrome is not clear. Twenty-three patients, 11 men and 12 women, were hospitalized between 1985 and 1989 for examination of this type of abnormal paroxysmal movements (APM) occurring at night. In order to clarify the physiopathology of these abnormal nocturnal movement as focal epilepsy or a particular form of dystonia, we analyzed the personal and familial antecedents of all 23 patients, the polygraphic records during waking and sleep periods, and the results of neuroradiological examinations. Four patients were examined by positron emission tomography (PET) using i8F deoxyglucose. Symptoms first appeared between 3 and 28 years of age (M, 10.1) and developed over 1 to 20 years (M, 10.1). APM clearly occurred more commonly (greater than 90%) during sleep, usually during phases of slow-wave sleep. The sleeping patient opened his eyes and the motor signs then variously associated affective facial expression; axial postural modifications; tonic, dystonic or choreic postural movements of the limbs; pedalling; automatisms; disordered agitation and vocalization. The seizure was abruptly interrupted after 10 to 60 seconds. There was usually no postictal confusion. Thirteen patients clearly had clear epileptic antecedents: in 9, generalized tonic-clonic seizures; in 4, focal epileptic status. During nocturnal polygraphic recording, 6 patients presented a generalized seizure following a period of APM.(ABSTRACT TRUNCATED AT 250 WORDS)

The adverse effects profile of levetiracetam in epilepsy is still being fully described. We recently published a Cochrane Review evaluating the effectiveness of levetiracetam, added on to usual care, in treating drug-resistant focal epilepsy. The five most common adverse effects were reported and analysed with no scope for reporting any less common adverse effects than those. Here, we report and analyse the remaining adverse effects (including the five most common). These were (in decreasing order of frequency) somnolence; headache; asthenia; accidental injury; dizziness; infection; pharyngitis; pain; rhinitis; abdominal pain; flu syndrome; vomiting; diarrhoea; convulsion; nausea; increased cough; anorexia; upper respiratory tract infection; hostility; personality disorder; urinary tract infection; nervousness; depression; aggression; back pain; agitation; emotional liability; psychomotor hyperactivity; pyrexia; rash; ECG abnormalities; decreased appetite; nasal congestion; irritability; abnormal behaviour; epistaxis; insomnia; altered mood; anxiety; bloody urine; diplopia; dissociation; memory impairment; pruritis; increased appetite; acne; and stomach discomfort. Only somnolence and infection were significantly associated with levetiracetam. When adverse effects pertaining to infection were combined, these affected 19.7% and 15.1% of participants on levetiracetam and placebo (relative risk 1.16, CI 0.89-1.50, Chi(2) heterogeneity p = 0.13). Somnolence and infection further retained significance in adults while no single adverse effect was significant in children. This review updates the adverse effects profile data on levetiracetam use by empirically reporting its common and uncommon adverse effects and analysing their relative importance statistically using data from a group of trials that possess low Risk of Bias and high Quality of Evidence GRADE scores.
