Error-related negativity abnormalities in generalized anxiety disorder and obsessive-compulsive disorder.

Prog Neuropsychopharmacol Biol Psychiatry 2011 Jan 24;35(1):265-72. Epub 2010 Nov 24.

Shanghai Mental Health Center, Shanghai Jiaotong University School of Medicine, Shanghai 200030, China.

Enhanced error-related negativity (ERN) has been associated with anxiety among both non-clinical and clinical populations. However, whether it is abnormal among adult patients with generalized anxiety disorder (GAD) is still unknown. The present study investigated it across GAD and obsessive-compulsive disorder (OCD).

A review of electroencephalograms done at the Kenyatta National Hospital, Nairobi.

East Afr Med J 2008 Feb;85(2):92-7

Department of Medicine, Aga Khan University Hospital, Nairobi, P. O. Box 19624-00202, Nairobi, Kenya.

Background: Electroencephalogram based studies done elsewhere suggest that epileptiform activity originates predominantly from the left cortical hemisphere. There is evidence that partial epilepsies (focal spike and wave epileptiform discharges on tracings) connotes focal; secondary structural cortical dysfunction. Studies seeking similar findings have not been done locally. Read More

Frontal midline theta rhythm: differentiating the physiological theta rhythm from the abnormal discharge.

Clin Electroencephalogr 1994 Jan;25(1):30-5

Department of Psychiatry, Juntendo University School of Medicine, Tokyo, Japan.

The theta rhythm that appears in the frontal midline was studied morphologically and clinically in EEGs performed on 788 patients and 161 normal subjects in their late teens or older. This theta rhythm was classified into 2 types. The Type 1 theta rhythm appeared in short bursts maximally in the Fz lead and spread mainly to the anterior region. Read More

Effect of sleep on the electrographic manifestations of epilepsy.

Authors:
A J Gabor M Seyal

J Clin Neurophysiol 1986 Jan;3(1):23-38

Alterations in the level of arousal have profound predictable effects on the electrographic manifestations of epileptogenic abnormalities. The changes produced by sleep are dramatic in patients with generalized epilepsy as compared to patients with partial epilepsy. The epileptiform complexes associated with the generalized epilepsies show changes in spatial distribution, voltage, temporal sequencing, and waveform morphology. Read More
