[Might it be epilepsy? What should the genera;l practitioner look out for in differential diagnosis].

Both a missed diagnosis of epilepsy, a wrong diagnosis of epilepsy as something else, and a misdiagnosis of something else as epilepsy can have serious consequences for the patient, e.g. therapeutic deviations, or physical, physical and social complications. Not all possible but some important problems of differential diagnosis are discussed, including both typical misdiagnoses of epileptic seizures as cardiac synkope or pseudoepileptic fits, oversight of subtle manifestions of epilepsy such as absences, juvenile myoclonic epilepsy, and isolated auras, and misdiagnoses as epilepsy of migraine variants, syncope, episodic ataxias, narcolepsy, and parasomnias.

Syndromic classification in the management of childhood epilepsy.

Epilepsy syndromes, defined as clusters of symptoms or signs occurring consistently together, form the basis of the currently accepted classification of the epilepsies. The concept of epilepsy syndrome is practical for the diagnosis, prognosis, orientation of treatment, and selection of appropriate investigations, but it is of variable specificity and usually does not give information on causes and mechanisms of an epilepsy. Some syndromes, such as childhood absences, partial epilepsy with centrotemporal spikes, or juvenile myoclonic epilepsy, are precisely characterized while other syndromes such as grand mal on awakening or the multiple syndromes with myoclonic seizures are poorly delineated. The usefulness of the concept is limited to well-defined and generally accepted syndromes and many cases of epilepsy do not fit easily in recognizable syndromes.

Late onset absence seizures in multiple sclerosis: a case report.

A 38-year-old woman was admitted to hospital because of generalized tonic-clonic attacks and late onset absence seizures. EEG and Video-EEG showed 3-4 hz generalized spike and wave discharges lasting 1-8 seconds, which were associated with impairment of consciousness and unresponsiveness. MR scan revealed multiple demyelinating lesions, including the most prominent one in the mesial frontal region that we suppose might be responsible for electroclinical absence seizures. After investigation the diagnosis of multiple sclerosis was made. Possible pathophysiological mechanisms and differential diagnosis of tonic-clonic and absence seizures in MS are discussed.

MRI volumetry shows increased anterior thalamic volumes in patients with absence seizures.

The interaction between thalamus and cortex appears to be critical to the pathophysiology of idiopathic generalized epilepsies (IGEs). The objective of this study was to investigate thalamic volumes of a group of patients with IGEs using high-resolution MRI. Thalamic segmentation was performed by the same rater, who was unaware of the diagnosis. Thalamic volumes were divided into anterior half and posterior half. One hundred forty-seven patients were scanned (71 with juvenile myoclonic epilepsy, 49 with generalized tonic-clonic seizures only, and 27 with absence epilepsy). Subgroup analyses with corrections for multiple comparisons showed that, when compared with those of controls, anterior thalamic volumes were increased in patients with absence epilepsy and juvenile myoclonic epilepsy with absence seizures, but not in patients with generalized tonic-clonic seizures only and juvenile myoclonic epilepsy without absence seizures. Our results demonstrated that the anterior thalamus is structurally different in patients with IGEs and absence seizures as compared with patients with IGEs without absence seizures.
