[How to examine a patient with higher cortical dysfunction at bedside]

Area of Science:

• Neuropsychology
• Neurology
• Cognitive Science

Context:

• Neuropsychological assessment has evolved significantly from its early role in diagnosing and localizing cerebral lesions.
• Advancements in neuroimaging have reduced the reliance on neuropsychology for lesion localization.
• Current applications focus on detailed behavioral descriptions for patient care, treatment, and rehabilitation.

Purpose:

• To highlight the evolving role of neuropsychological evaluation in clinical practice.
• To emphasize the importance of clinical history and patient self-awareness in diagnosing higher cortical dysfunction.
• To underscore the utility of neuropsychological tests in estimating premorbid abilities and identifying cognitive deficits.

Summary:

• Neuropsychological evaluations are now primarily used for detailed behavioral descriptions to guide patient care, treatment, and rehabilitation.
• Neurologists must consider clinical history, patient recognition of deficits (e.g., apraxia, optic ataxia), and anatomical lesion localization.
• Tests like the Wechsler Adult Intelligence Scale-Revised (WAIS-R) are crucial for assessing overall intellectual functioning and identifying specific cognitive alterations.

Impact:

• Informs clinical decision-making for patients with higher cortical dysfunction.
• Provides a framework for neurologists to systematically assess and understand cognitive impairments.
• Establishes a baseline for cognitive function, aiding in the planning of effective interventions and rehabilitation strategies.
