Transient Capgras Syndrome Secondary to Bilateral Ischemic Stroke: A Case Report.

Capgras syndrome is one of a variety of delusional misidentification syndromes that can be associated with acute ischemic stroke, neurodegenerative disease, or metabolic conditions. Most cases reported in the literature are associated with frontal and/or parietal lobe involvement. Transient Capgras syndrome is rare but has been reported. We present a case of transient Capgras syndrome following bilateral cerebral ischemic infarcts in the frontal, parietal, and temporal regions, and involving the right prefrontal cortex. To our knowledge, transient Capgras syndrome with rapid resolution over a period of days is rare.
