Cognitive screening in brain tumors: short but sensitive enough?

Area of Science:

• Neuropsychology
• Neuro-oncology
• Cognitive Assessment

Background:

• Cognitive deficits in brain tumor patients are often considered mild and non-specific.
• Existing cognitive screening tools may lack the sensitivity to detect subtle or focal impairments.
• Neuropsychological evaluations tailored to specific deficits are needed for improved detection.

Purpose of the Study:

• To compare the sensitivity of the Montreal Cognitive Assessment (MoCA) against a brief, tailored cognitive assessment (CA).
• To identify cognitive deficits in an unselected sample of primary brain tumor patients (gliomas, meningiomas).
• To evaluate the clinical utility of MoCA versus CA in this patient population.

Main Methods:

• Assessed cognitive function in primary brain tumor patients using MoCA and a tailored CA.
• Compared performance based on the number of impaired patients and cognitive domains.
• Conducted specific analyses comparing MoCA-intact and MoCA-impaired groups on detailed cognitive tests.

Main Results:

• The MoCA demonstrated extremely poor sensitivity in detecting cognitive impairments in brain tumor patients.
• MoCA-impaired patients showed deficits primarily in naming and word fluency compared to MoCA-intact patients.
• A brief, tailored CA was found to be necessary for more accurate cognitive deficit identification.

Conclusions:

• The MoCA is not sufficiently sensitive for evaluating cognitive function in primary brain tumor patients.
• Tailored cognitive assessments are essential for accurate diagnosis and management of cognitive impairments in this group.
• Findings have implications for clinical management, planning, and neuropsychological assessment strategies for brain tumor patients.
