Abstract
BACKGROUND: The reversed clock phenomenon results in the transposition of objects from one side to another. Its major manifestation consists in the reversal of clock numbers in clock-drawing test. It could be due to a stroke disrupting attentional cerebral network. This phenomenon usually regresses in a few days. OBJECTIVE: To report a case of reversed clock phenomenon with disorders of space representation that did not regress spontaneously. DESIGN: Case report. PATIENT: A 67 year-old woman was referred due to headaches associated with gait disorder, visual field deficit and disturbance of space representation. RESULTS: Magnetic resonance imaging demonstrates two right cerebral infarcts mainly localized in the parieto-occipital region. A week after her stoke, clinical testing confirms a reversed clock phenomenon. The patient placed the hands of a clock in the opposite direction of what was specified. She got lost at home locating rooms in directions opposite to their real ones. Rehabilitation sessions partially improved these manifestations. CONCLUSION: Although it usually improves in a few days, reversed clock phenomenon can persist longer. Rehabilitation sessions based on localization exercises may be helpful in such situations.
