Have a look at the following few pages, which follow one another. These occur at the time of a dissociative seizure. What do you make of the 9-10 Hz alpha frequencies over the frontal regions? Do you ...
This adult is asleep, and the conclusion seems pretty straightforward, doesn't it?
The wave has a "field" and a spike morphology, followed by a typical slow wave that is in the same distribution...
Roland made the point at the bottom of this post Small sharp spikes; wading into the controversy. that small sharp spikes are often missed on bipolar montages and are particularly noticeable on refere...
The patient is 30+ years old and asleep.
What do you make of the following wave that occurs between the 7th and 8th ECG beats?
The following represents the same epoch on the coronal monta...
This young adult is asleep at approximately 02h00. The differential diagnosis is of epilepsy and non-epileptic seizures/functional seizures.
Using the criteria of morphology and field, you m...
When Gibbs and Gibbs first drew attention to these waves in 1952, because they were commonly seen in patients with epilepsies, they classified these discharges as epileptiform in nature. However, thei...
A new study has just been published in Epilepsia that corroborates previous studies demonstrating the efficacy of epilepsy surgery in reducing epilepsy-related mortality. What makes this one different...
The above is a summation of waves that includes the 4th ECG beat. However, it has a large field and hence is more than just the ECG beat. There are suspicions of a small sharp spike that is coinc...
The following is the recording from a 40+y patient, who has been seizure-free for 11 years. Over the past 1-2 years his/her memory has objectively declined, prompting further investigation. The 24-hou...
As healthcare practitioners who primarily see problems in the human brain, it is incumbent on us to ensure that foetuses' brains are protected as best as humanly possible, especially from iatrogenic h...
A paediatrician telephoned me about a nine-year-old who had a generalized tonic-clonic seizure in sleep, wanting to know whether an MRI and EEG should be requested. The child is intellectually and dev...
Herewith another example:
The above looks a little like a sharp and slow wave at F7-M1-F3-FP1.
Then look at it on the standard AP bipolar montage; see below.
It looks far less conspicu...
