Pathophysiology
A patient with cerebral hypoxia exhibited severe bilateral hippocampal atrophy and significant spatial learning deficits, suggesting a critical role of the hippocampus in spatial orientation [PMID:12486268].
Clinical Presentation
The patient demonstrated severe difficulty orienting in new environments but maintained intact verbal and visual-object learning abilities, highlighting a specific spatial memory impairment [PMID:12486268].
Diagnosis
Evaluation revealed that the patient could not learn routes in a maze without visual cues, indicating that spatial learning tasks are crucial for diagnosing topographical disorientation [PMID:12486268].
