“…The special report of the ILAE Task Force on classification of status epilepticus provides examples of selected electroclinical syndromes according to age and proposes de novo or relapsing ASE of later life as an epileptic condition occurring in elderly patients (60 years). Although the qualifier “later life” is intuitive and descriptive, this terminology has been used in the past in different studies to include patients younger than 60 years of age [3, 9], making comparisons among different reports more challenging. Using the term “ASE of late on setorlate‐onset ASE” mightavoidthis confusion.…”

Objective. We describe the clinical, electroencephalographic and neuroimaging findings of older patients with typical absence status epilepticus (ASE). Methods. This investigation was a retrospective analysis of prospectively collected consecutive patients between January 2011 and October 2021. All rhythmic, synchronous and symmetric epileptiform discharges and normal background on video‐electroencephalogram (vEEG) were included. Results. Six patients were identified with a diagnosis of typical ASE. The mean age was 67 years. Five could be classified as idiopathic generalized epilepsy (IGE) though two had been erroneously categorized as cryptogenic focal epilepsy (FE). In one, the episode of ASE was thought to represent the beginning of late‐onset IGE (de novo late‐onset typical ASE). In all cases, ASE was controlled within the first 24 hours. Significance. Typical ASE is a rare cause of confusion in the elderly population requiring urgent vEEG evaluation. It most frequently represents reactivation of a previous IGE, although it can be the form of presentation in elderly people with epilepsy that begins in childhood or adolescence and that has not been diagnosed or treated. It may be rarely the debut of (de novo) late‐onset IGE.

“…These investigations have led to a syndromic description that facilitates diagnosis, early treatment, and characterizes the long‐term prognosis and risk of recurrence [1]. Single case reports aside, little study has focused on typical absence status epilepticus (ASE) in the elderly, or later life [2, 3].…”

“…Some argue that this form of seizures is due to epileptically-enhanced stretch reflex. 6 Classically, rolandic sensory-motor cortex or supplementary motor area is involved in the epileptic network. Hence, the provoking stimulus and the seizure are confined to a single functional cerebral network.…”

Proprioceptive-induced seizure in diabetic non-ketotic state: A video case report

A 63-year-old diabetic gentleman with proprioceptive-induced seizures is reported. Marked hyperglycemia due to discontinuation of anti-diabetic medication was the precipitating cause. Distinctive clinical feature of this case was recurrent focal motor seizures involving the left upper limb precipitated by volitional movements of the same limb and self-aborted by holding the affected limb with the contralateral limb. This was accompanied by left brachial weakness without corresponding lesions on cranial MRI. Despite rapid achievement of euglycemia, seizures persisted and required anticonvulsant polytherapy for effective control.

“…In these RSs (Pts 1-7, Table 1), tapping [28][29][30], rubbing [31] or tooth-brushing [17,21] the ictal semiology may resemble a spinal reflex-loop (Pt 1) [33,34]: the stimulation of the limb, be it light touch, running or tension, evokes motor jerks of the same limb [33].…”

We aim to study the mechanism of reflex seizure triggering in close link with the system-epilepsy concept. Method: We use data and theories presented in the literature and scrutinize a few illustrative cases. Conclusions: The prerequisite of seizure triggering is an epilepsy-prone brain network. When it is activated, it may produce seizures manifesting the function(s) of the same system. Beyond classical reflex seizures triggered by sensory-motor stimuli, we extend the reflex-epilepsy concept to seizures induced by the normal activation of epilepsy-prone systems e.g. praxis-induced seizures and those of sleep/wake system epilepsies elicited by falling asleep (absences) or arousals from NREM sleep (seizures of genetic frontal lobe epilepsy). We suggest that normal functioning of epilepsy-prone systems may trigger seizures in epilepsies in general.
