Cerebral hemodynamic compromise associated with limb shaking XXXX and focal EEG slowing.

We report four cases of cerebral hemodynamic compromise identified over a five year period. Cerebral hemodynamic compromise is characterized by reversible attacks of regional @entity2806 affecting @entity1 with occlusive disease of main arteries supplying blood to the brain. All four of our @entity1 had @entity432 (ICA) often associated with high grade @entity850 or occlusion of the contralateral internal carotid artery and/or major intracranial arteries. All @entity1 developed likely limb shaking transient @entity63 attacks (TIAs) which occur during acute exacerbation of regional @entity1779 . These events often trigger EEG testing because of suspicion of @entity410 . Each @entity1 also had focal delta EEG slowing without evidence of noteworthy structural lesions on imaging scans. A discrepancy or mismatch between these testing results occurred. The @entity1 ' focal delta EEG slowing was attributed primarily to resting regional @entity1779 . Diagnosis of cerebral hemodynamic compromise may be delayed when limb shaking @entity4905 is misdiagnosed as a @entity302 or when regional @entity1779 is not considered as a potential cause of focal delta EEG slowing in older @entity1 that have normal structural imaging studies. Our cases are discussed in light of the relevant EEG and clinical characteristics that have been described in reports of limb shaking @entity4905 and structural imaging/focal delta EEG slowing mismatches.
