Overview
Post-chemotherapy cognitive impairment (also known as chemotherapy-induced cognitive dysfunction) is defined as the cognitive impairment that can result from chemotherapy treatment. Post-chemotherapy cognitive impairment is characterized by changes in memory, fluency, and other cognitive abilities that impeded their ability to function as they had pre-chemotherapy. Approximately 20-30% of patients that undergo chemotherapy experience some level of post-chemotherapy cognitive impairment. Recent studies suggest further investigation on the underlying mechanisms of cognitive impairment.
Historical Perspective
- Post-chemotherapy cognitive impairment was first discovered by [scientist name], a [nationality + occupation], in [year] during/following [event].

Pathophysiology
- The pathogenesis of post-chemotherapy cognitive impairment is characterized by [feature1], [feature2], and [feature3].
- The [gene name] gene/Mutation in [gene name] has been associated with the development of post-chemotherapy cognitive impairment, involving the [molecular pathway] pathway.

- On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of post-chemotherapy cognitive impairment.
Causes
- The causes for post-chemotherapy cognitive impairment remain unknown.[1]
Differentiating post-chemotherapy cognitive impairment from other Diseases
