Introduction. Although ictal blinking is significantly more frequent in generalized epilepsy, it has been reported as a rare but useful lateralizing sign in focal seizures when it is not associated with facial clonic twitching. This study aimed to raise awareness of eye blinking as a semiological lateralizing sign. Method. Our database over an 11-year period reviewed retrospectively to assess patients who had ictal blinking associated with focal seizures. Results. Among 632 patients, 14 (2.2%), who had 3 to 13 (7 ± 3) seizures during video-EEG monitoring, were included. Twenty-five percent of all 92 seizures displayed ictal blinking and each patient had one to five seizures with ictal blinking. Ictal blinking was unilateral in 17%, asymmetrical in 22% and symmetrical in 61%. The blinking appeared with a mean latency of 6.3 s (range 0-39) after the clinical seizure-onset, localized most often to fronto-temporal, then in frontal or occipital regions. Blinking was ipsilateral to ictal scalp EEG lateralization side in 83% (5/6) of the patients with unilateral/asymmetrical blinking. The exact lateralization and localization of ictal activity could not have been determined via EEG in most of the patients with symmetrical blinking, remarkably. Conclusions. Unilateral/asymmetrical blinking is one of the early components of the seizures and appears as a useful lateralizing sign, often associated with fronto-temporal seizure-onset. Symmetrical blinking, on the other hand, did not seem to be valuable in lateralization and localization of focal seizures. Future studies using invasive recordings and periocular electrodes are needed to evaluate the value of blinking in lateralization and localization.

Upward Deviation

Background Paroxysmal tonic upgaze (PTU) is an infantile-onset paroxysmal neurological disorder that is characterized by episodes of sustained conjugate upward eye deviation. The paroxysmal abnormal eye movements need to be differentiated from seizures. We report a case of PTU with occipital discharge on electroencephalography (EEG), which made the diagnosis more complicated. Case presentation A 6-month-old girl presented with paroxysmal upward deviation or left strabismus of the eyes, with a bowed head, lowered jaw, raised eyebrows, closed lips, and slight grin. Each episode lasted for a few seconds, and episodes occurred multiple times per day. EEG showed spike waves in the right occipital region, and the girl was initially misdiagnosed with epilepsy. After further analysis using video EEG, we corrected her diagnosis as PTU and stopped the administration of an antiepileptic drug. Conclusion PTU accompanied by discharge on EEG may lead to a misdiagnosis. Video EEG monitoring, and especially the analysis of EEG traces synchronized with attacks, can provide evidence to distinguish between seizures and non-epileptic events.

Abstract Introduction Cataplexy (associated with narcolepsy) is difficult to differentiate from conditions such as seizure, syncope or TIA, but using validated clinical tools can help. We report a case that was mistakenly diagnosed as cataplexy, delaying diagnosis and treatment of his underlying seizures. Report of Case A 42 years old male presented with “freezing spells” described as spontaneous episodes of weakness in his knees. He may stagger and drop objects but had never fallen. He denies loss of consciousness. Post-ictally, he takes a moment to readjust his body and returns to baseline. There was no warning or aura before the episodes. These spells initially occurred 1-2 times/year in 2002, then progressed to 1/month by 2006 and then increased to 15 times/day in Jan 2019, lasting 5-10 seconds at a time. He became hesitant to drive. He was evaluated by a pulmonologist/sleep specialist. PSG showed Mild OSA but MSLT wasn’t suggestive of Narcolepsy. He was prescribed CPAP but stopped after 6 months since it didn’t improve his symptoms. He was prescribed Venlafaxine to treat presumptive Cataplexy, without any benefit. Eventually, he was referred to neurology/sleep clinic. Cataplexy questionnaire was administered and was negative: specifically, there were no emotional triggers of his episodes, such as hearing a joke, laughing or crying. Due to the stereotyped nature of his spells, he was referred to epilepsy specialist. He underwent 72 hours video EEG monitoring which showed that his clinical episodes were associated with EEG abnormality, suggestive of frontal lobe epilepsy. He was placed on Keppra and Oxcarbazepine. On follow up visit, he reported improvement in seizure frequency from 10-20/day to 1-2/day. Conclusion A validated1 clinical Tool such as Stanford Cataplexy questionnaire helps in differentiation of Cataplexy from other forms of transient muscle weakness. It can prevent 15 years delay in diagnosis and treatment of patients, or use of unnecessary medication.

Patients affected by periventricular nodular heterotopia are frequently characterized by focal drug-resistant epilepsy. To investigate the role of periventricular nodules in the genesis of seizures, we analyzed the electroencephalographic (EEG) features of focal seizures recorded by means of video-EEG in 10 patients affected by different types of periventricular nodular heterotopia and followed for prolonged periods of time at the epilepsy center of our institute. The ictal EEG recordings with surface electrodes revealed common features in all patients: all seizures originated from the brain regions where the periventricular nodular heterotopia were located; EEG patterns recorded on the leads exploring the periventricular nodular heterotopia were very similar both at the onset and immediately after the seizure's end in all patients. Our data suggest that seizures are generated by abnormal anatomic circuitries, including the heterotopic nodules and adjacent cortical areas. The major role of heterotopic neurons in the genesis and propagation of epileptic discharges must be taken into account when planning surgery for epilepsy in patients with periventricular nodular heterotopia.
