Cognitive And Behavioral Dysfunctions Caused By Caudate Infarction: A Case Report And Literature Review

The caudate nucleus is important in the modulation of motor functions and may influence cognitive and mental functions. However, cases of cognitive and behavioral disorders caused by caudate stroke are rare in practice. We report a case of 79-year-old male patient who presented with abrupt onset of cognitive and behavioral dysfunctions. His prominent symptoms included rambling, memory impairment, emotional indifference, reduced words, and lack of care for his family and surroundings. Computed tomography and magnetic resonance imaging of the brain revealed an acute infarction in the head of the left caudate nucleus. The present case and review contribute to the growing body of evidence that the caudate nucleus plays a crucial role in controlling cognitive and behavioral processes.
