Which of the following is NOT classified as a Type I neurological complication following cardiac surgery?

Type I neurological complications following cardiac surgery are typically categorized as direct consequences of cerebral ischemia, which can lead to significant, often irreversible damage. Coma, transient ischemic attack (TIA), and stroke all fall within this classification as they relate directly to acute neurological events resulting from compromised cerebral blood flow.

Although memory loss can occur following cardiac surgery, particularly as a part of post-operative cognitive decline, it is not classified under Type I complications because it is generally seen as a more gradual, less immediate outcome. Memory loss may stem from a variety of factors, including longer-term cognitive changes or complications like delirium rather than acute neurological injury. Therefore, it is distinguished from other immediate complications like coma, TIA, and stroke, which are primarily characterized by sudden occurrences of neurological deficits.
