[9] [10] These effects can impair a chemotherapy patient's ability to understand and make decisions regarding treatment, perform in school or employment and can reduce quality of life. [10]
Research shows that children with cancer are at risk for developing various cognitive or learning problems. These difficulties may be related to brain injury stemming from the cancer itself, such as a brain tumor or central nervous system metastasis or from side effects of cancer treatments such as chemotherapy and radiation therapy.
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 ...
Childhood AML treatment usually consists higher dose chemotherapy given over a shorter period of time compared to ALL treatment. Due to this shorter and more intense treatment, side effects are also more intense.

Its causes are under investigation and occurs commonly in older patients and those with pre-existing cognitive impairment. [2] The causes of POCD are not understood. It does not appear to be caused by lack of oxygen or impaired blood flow to the brain [3] and is equally likely under regional and general anesthesia.
While more than one cause may exist in the same person stimulating symptoms via more than one pathway, the actual cause of nausea and vomiting may be unknown in some people. The underlying causes of nausea and vomiting may in some cases not be directly related to the cancer. The causes may be categorized as disease-related and treatment-related ...
