MRI Brain revealed bilateral thalamic strokes. Transthoracic echocardiogram (TTE) showed an intraatrial septal aneurysm with right to left shunt. Transesophageal echocardiogram (TEE) revealed the same. No intracardiac thrombus was found. Lower extremity dopplers were unremarkable. Carotid duplex revealed 0-15% bilateral ICA stenosis. Neuroophthalmologic evaluation revealed evidence of a supranuclear vertical gaze palsy OU (diminished up and down gaze). Neuropsychologic assessment 1/12-15/93 revealed severe impairment of anterograde verbal and visual memory, including acquisition and delayed recall and recognition. Speech was effortful and hypophonic with very defective verbal associative fluency. Reading comprehension was somewhat preserved, though she complained that despite the ability to see type clearly, she could not make sense of words. There was impairment of 2-D constructional praxis. A follow-up Neuropsychology evaluation in 7/93 revealed little improvement. Laboratory studies, TSH
