<p style="text-align: left;">OIRDA stands for occipital intermittent delta activity. OIRDA is a delta pattern that often spreads from the occipital leads to the posterior temporal regions on both the right and the left hemispheres. This pattern is usually seen in children, however the clinical significance of it is not yet agreed upon within the neurological community. While OIRDA has been linked to epileptic disorders, it has also been linked to encephalopathy. There are some cases of OIRDA reported that have not deomnstrated pathological significance.&nbsp;<br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/oirda-seen-10-year-girl.png" alt="OIRDA seen in a 10-year old girl" width="1007" height="750" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Figure : OIRDA seen in a 10-year old girl<br></p>
