“…Hence, the slow falls in our patient agree with the atonic seizures that start partially, as reported by Satow et al, 15 who described partially starting atonic seizures in 2 patients with frontal and parietal lobe epilepsy. Fast activity with low voltage and rhythmic spikes was reported to have been observed in the patients' ictal EEG recordings.…”

“…Although atonic seizures are placed among generalized seizures, according to the International League Against Epilepsy, atonic seizures that start partially have also been reported. 14,15 Atonic seizures that start partially may be of 2 types. Although in the first one, sudden tonic posture forms before the fall, in the other, the fall occurs without any motor phenomenon.…”

Different Seizure Types and Skin Lesions in Oculocerebrorenal Syndrome of Lowe

et al. 2007

View full text Add to dashboard Cite

Oculocerebrorenal syndrome of Lowe is an X-linked recessive disorder localized to Xq24-26.1. The phenotypic features of this disorder are Fanconi-type renal failure, mental retardation, and various eye abnormalities. Seizures may accompany the disease, and the skin-related findings are poorly defined. This case of a 9-year-old patient, diagnosed as having and followed for oculocerebrorenal syndrome of Lowe, has been presented for his seizures, which were initially myoclonic but subsequently atonic, and for his skin findings, understood to be trichoepithelioma, cystic in nature, and stemming from mature hair follicles. In monitoring the disease, the manifestation of the seizures as atonic seizures accompanied by focally initiated secondary generalized epileptic discharges is a finding previously undefined in oculocerebrorenal syndrome of Lowe. Moreover, the presence of dermal findings of a cystic nature is reported in few cases of this syndrome. In this rare syndrome, it is necessary to be aware of the presence of atonic seizures, which have an association with the progression of the disease that has not been previously reported in the literature, and of the cystic dermal lesions as part of the syndrome.

“…A typical example is the successful surgery for patients with Lennox-Gastaut syndrome (LGS). It has been verified that a special group of LGS patients may have associated focal brain lesions (Bladin, 1985;Satow et al, 2002;Lee et al, 2014). Similarly, the aetiology of West syndrome has gradually changed from generalised seizures to seizures with multiple origins (Jonas et al, 2005;Komaki et al, 2001;Kang et al, 2006;Wyllie, 1996).…”

Background: Although the causes of stroke recurrence are well known, no particular study deals with the specific issue of late-onset transient worsening of the neurological deficit (TWND) after an ischaemic stroke. Patients and Methods: In this retrospective study the aetiology of the TWNDs in 101 patients was compared to the causes of transient ischaemic attacks (TIAs) in 115 patients. All patients had a full cardiovascular and neuroimaging examination according to current guidelines. An electroencephalogram (EEG) was performed when necessary. The diagnosis of inhibitory seizures was retained when the EEG showed periodic lateralized epileptiform discharges or intermittent rhythmic delta activities, or when the patient developed typical seizures afterwards. Results: Arterial hypertension and diabetes were more prevalent vascular risk factors in TWND patients. Small-vessel disease and inhibitory seizures were a more frequent cause of TWNDs than of TIAs. Extracranial large-vessel disease predominates in TIA patients. The global prevalence of cardiac diseases as cause of TIAs and TWNDs was the same, although severe ulcerous plaques of the aortic arch and patent foramen ovale with atrial septum aneurysm occurred more frequently in TWND patients. Conclusions: The most frequent causes of late-onset TWNDs were different from those of TIAs. Apart from repeated neuroimaging of the brain, exhaustive cardiac investigations and EEG are mandatory in TWND patients.
