Rational manipulation of digital EEG: pearls and pitfalls.

Sometimes slower activity was seen over the frontal and central regions. There was a paucity of slow wave and REM sleep.

The awake background was normal. A sleep study at age 20 years showed absence of slow-wave sleep and reduced amounts of REM sleep, without any evidence of central or obstructive apnea. Between age 16 and 27 years, the patient tried and failed multiple anticonvulsants: oxcarbazepine, lamotrigine, levetiracetam, zonisamide, valproic acid, acetazolamide, pregabalin, phenytoin, clorazepate, and lacosamide.

A vagal nerve stimulator was also implanted without success. The patient underwent cVEEG again at age 26 years figure because she believed her seizures were causing increasing memory impairment, anxiety, and fatigue affecting her work.

At that time, she was treated with phenytoin, pregabalin, clorazepate, and lacosamide. EEG initially showed multiple events occurring during stage 2 sleep. These occurred on average every 60 seconds, lasting on average 6—8 seconds.

There were a few seizures lasting up to 60 seconds. The seizures and their electrical correlate were similar to what was seen on prior studies.

Due to frequent seizures, there was a paucity of slow-wave sleep and complete absence of REM sleep. On the second day of her hospital admission, a 7-mg nicotine patch was applied about 2—3 hours before bedtime.

There was almost complete resolution of clinical and electrical events. The duration of slow-wave sleep increased and REM sleep was recorded. Sort order. Jul 06, M G rated it really liked it. A great case-based learning tool for EEG that motivates you to read independently using guiding questions.

This last observation is central in the differential diagnosis of symptomatic generalized epilepsies, where the background is typically disorganized and slow Markand, Another important conclusion of this study is that atypical EEG abnormalities may vary according to the state of arousal and seizure-free duration.

Atypical morphology of discharges can have a frequency fourfold greater during non-REM sleep, and the probability of their symmetry is estimated to decrease by about one percentage point for each additional year of seizure-free duration.

From the pathophysiological point of view, asymmetries and focal abnormalities found in the EEG of generalized epilepsies can probably be explained by a selective involvement of the thalamo-cortical circuit, at cellular synaptic or regional topographic levels, expressing mutations involving the ionic channels and neurotransmitters, asymmetrically distributed over the cerebral cortex.

On the other hand, the atypical morphological features are directly determined by the variations of the synchronization of brain electrical activity observed during the stages of sleep, causing fragmentation of generalized discharges. Seneviratne and Cook, Focal discharges, asymmetries and focal onset of paroxysms may lead to a misdiagnosis of focal epilepsy; atypical spike-wave complexes without spikes can be misdiagnosed as delta-slowing; and the presence of generalized paroxysmal fast rhythms might create confusion about a diagnosis of Lennox—Gastaut syndrome.

First, there may be a problem in choosing the most suitable drug for treating that patient. For example, narrow-spectrum drugs e.

However they are less effective than broad-spectrum agents e. Published by Elsevier Ireland Ltd.In the following years, the patient had multiple cVEEG admissions because of increased seizure frequency.

Are the fast frequencies shown in the tracing normal? Typical interictal epileptiform discharges in genetic generalized epilepsy.

What is the drop in potential at a 5 kO resistor for a current of 10 pA? There were a few seizures lasting up to 60 seconds.

Because G1 and G2 transmit unequal voltages. The patient was later managed with behavioral modification strategies and mood-stabilizing agents.
