Eeg Results Abnormal Left Temporal Lobe. Bitemporal and bioccipital slow waves often paroxysmal in nature were the most common abnormalities. Increased LORETA activity was found in the BERS group as compared to the controls in the left and right temporal lobes fusiform gyri posterior parts of the superior middle and inferior temporal gyri and in the angular gyri in the parietal lobes in the 4-6 Hz VNBs mainly at 5 Hz.
So it is a totally non-specific finding but suggest a focal problem. Tumors in other locations such as the thalamus also may produce temporal delta. Left temporal slowing on an EEG can be seen is mass lesions tumors abcesses strokes or as a result of a recent seizure a part of the recovery of the brain from a seizure.
Those with focal seizures temporal lobe epilepsy comprises the bulk of patients and this region in the EEG is also the location that is most subject to misinterpretation 2829.
In ten patients the EEG was considered abnormal. In all records with temporal slow waves the foci of the slow wave were at anteriotemporal or midtemporal areas. Temporal lobe seizures may present even more of a coping challenge because people may not recognize the unusual behavior as a. Abnormal activity in the left temporal lobe can result from damage to the left temporal lobe itself or an area that feeds information into it.
