<p>Cerebro-vascular disorders can be indicated by a slowing of alpha at one site. The slow edge of alpha tracks ischemia. An indication of a vascular issue (or impeded flow dynamics) is the presence of headaches or any sort of similar issue.&nbsp; In Nuwer et al (1997) there is a finding in cerebrovascular disease that show ischemia-related cerebral impairment to be seen in focal features (perhaps similar to the finding of slowing in the right posterior temporal lobe).&nbsp;</p><p>When there is a lack of blood flow and oxygen to the area, there is often a consequential slowing of alpha at the area, sometimes into the theta range. As an area degrades, sometimes the alpha slows considerably below the normal alpha band (i.e. less than 8hz). A slowed alpha can represent a compromise of blood flow, and consequentially oxygen, to an area, which will lead to ischemia. The dip in alpha frequency will indicate how severe the ischemia is (Classen and Foreman, 2012). When cerebral blood ﬂow (CBF) becomes compromised, changes occur in both the metabolic and electrical activity of cortical neurons, with associated EEG changes.</p><p></p>
