Pretrigeminal neuralgia

Pretrigeminal neuralgia.

Eighteen patients who subsequently developed typical trigeminal neuralgia experienced a prodromal pain termed "pre-trigeminal neuralgia." These patients described their prodromal pain as a toothache or sinusitis-like pain lasting up to several hours, sometimes triggered by jaw movements or by drinking hot or cold liquids. Typical trigeminal neuralgia developed a few days to 12 years later, and ...

Pretrigeminal neuralgia

Typical trigeminal neuralgia, brief electric shock like pain along distribution of trigeminal nerve, is well documented in literature but not much is available about pre trigeminal neuralgia. Pre-trigeminal neuralgia should be considered in the differential diagnosis of pain of dental origin because of its similar features.Symonds was the first person who noted dull, continuous and aching pain ...

The acute pretrigeminal rat.

In five rats the brainstem was transected at the pretrigeminal level. In the frontal cortex, desynchronized EEG activity dominated, while in the dorsal hippocampus theta activity of low frequency (about 4 cycle/s) was almost continuously present. Olfactory and visual stimuli and electrical stimulation of the posterior hypothalamus induced or increased cortical EEG desynchronization and increase...

Cerveau isolé and pretrigeminal rats.

Cortical and hippocampal EEG activity was analysed in 14 cerveau isole and 8 pretrigerninal rats. In the acute stage, waking EEG patterns were absent in the cerveau isole, whereas sleep EEG patterns were absent in the pretrigeminal preparations. However, already on the second day the EEG waking-sleep cycle recovered in the majority of rats. Paradoxically, stimuli directed to the caudal part of ...
