<unk> , also known as pump head, is a constellation of neurocognitive impairments attributed to cardiopulmonary bypass (CPB) during cardiac surgery.  Symptoms of<unk>  are subtle and include defects associated with attention, concentration, short term memory, fine motor function, and speed of mental and motor responses.  Studies have shown a high incidence of neurocognitive deficit soon after surgery, but the deficits are transient with no permanent neurological impairment.
