Postoperative cognitive dysfunction (POCD) is a decline in cognitive function (especially in memory and executive functions) that may last from 1–12 months after surgery, or longer. [1] In some cases, this disorder may persist for several years after major surgery. [2] POCD is distinct from emergence delirium. Its causes are under ...
Post-chemotherapy cognitive impairment (PCCI) (also known in the scientific community as "CRCIs or Chemotherapy-Related Cognitive Impairments" and in lay terms as chemotherapy-induced cognitive dysfunction or impairment, chemo brain, or chemo fog) describes the cognitive impairment that can result from chemotherapy treatment.
Postoperative cognitive dysfunction (also known as POCD and post-anesthetic confusion) is a disturbance in cognition after surgery. It may also be variably used to describe emergence delirium (immediate post-operative confusion) and early cognitive dysfunction (diminished cognitive function in the first post-operative week). Although the three ...
Delirium occurs in 11–51% of older adults after surgery, in 81% of those in the ICU, and in 20–22% of individuals in nursing homes or post-acute care settings. [3] Among those requiring critical care, delirium is a risk factor for death within the next year.
Cognitive impairment is an inclusive term to describe any characteristic that acts as a barrier to the cognition process or different areas of cognition. [1] Cognition, also known as cognitive function, refers to the mental processes of how a person gains knowledge, uses existing knowledge, and understands things that are happening around them using their thoughts and senses.

They are defined by deficits in cognitive ability that are acquired (as opposed to developmental), typically represent decline, and may have an underlying brain pathology. [1] The DSM-5 defines six key domains of cognitive function: executive function, learning and memory, perceptual-motor function, language, complex attention, and social ...
The term minimal encephalopathy (MHE) is defined as encephalopathy that does not lead to clinically overt cognitive dysfunction, but can be demonstrated with neuropsychological studies. [ 16 ] [ 18 ] This is still an important finding, as minimal encephalopathy has been demonstrated to impair quality of life and increase the risk of involvement ...
Radiation therapy at doses around "23.4 Gy" was found to cause cognitive decline that was especially apparent in young children who underwent the treatment for cranial tumors, between the ages of 5 and 11. Studies found, for example, that the IQ of 5-year-old children declined each year after treatment by additional several IQ points, thereby ...
