Background:
Older women diagnosed with breast cancer may also have preexisting cognitive deficits. .
Objectives:
The aim of the current study is to describe errors on the clock-drawing test (CDT), which is used to screen for preexisting cognitive deficits in older women diagnosed with breast cancer. .
Methods:
This descriptive study included a convenience sample of women aged 69 years or older with a diagnosis of breast cancer. The CDT was used to screen for cognitive deficits, such as size of the clock, graphic difficulties, stimulus-bound response, conceptual deficit, spatial and/or planning deficit, and perseveration. Data were analyzed by the Rouleau qualitative error analysis. .
Findings:
Many older adult patients exhibit some abnormality on the CDT. Most abnormalities were spatial/planning difficulties. Cognitive screening should be included in the comprehensive assessment of older adults diagnosed with breast cancer to screen for preexisting cognitive limitations.
