Thalamic dementia: report of a case with unusual lesion location.
Thalamic dementia usually results from a bilateral paramedian thalamic infarction. We report a case with typical clinical and neuropsychological features of thalamic dementia, but with CT evidence of an unusual and asymmetrical location of ischemic lesions. Somatosensory evoked potential recordings were consistent with a left medial thalamic infarction, associated with a contralateral lesion, possibly at lemniscal level. This case suggests that thalamic dementia may develop following a unilateral paramedian thalamic infarction.
