Severe episodic memory impairment after strategic infarct: A case report.

Brain infarcts located in strategic regions often result in cognitive impairment. Based on a case study, this paper describes unusual and specific clinical and neuropsychological features of a strategic ischemic lesion in the left medial temporal lobe (MTL) structures. Taken together with the literature data, the case illustrates that a unilateral strategic infarct in MTL structures may result in severe impairment of episodic memory (EM), which refers to the ability to encode and retrieve personal experiences, including information about the time and place of an event and detailed description of the event itself.

Sleep and executive functions in older adults: A systematic review.

Introduction: A recent increase in studies suggests a role of age-related sleep changes in executive functions (EF). However, this relationship remains unclear and mixed results have emerged.

Objective: To investigate how age-related sleep changes may play an important role in the extent to which healthy older adults exhibit decline in EF.
