A Cognitive Neuropsychological Approach to Assessment of Patients with Brain Damage

Andrew Bateman PhD MCSP

This thesis is concerned with clinical assessment of the effects of brain damage. Cognitive neuropsychological models can be used to guide assessments with patients because different tests within a test battery can be devised to assess different levels within a particular model of normal cognitive functioning. The fine grained impairments that can result following brain damage may be missed if inappropriate assessment tools are

My first research study developed a reasonably brief but wide-ranging screening test to detect discrete cogni- tive impairments. In chapter 1, I review the strengths a n d weaknesses of cur ren t screening tes ts . The screening test I developed is presented in chapter 2, together with the rationale for the inclusion of partic- ular subtests, and data from the assessment of 72 stroke patients and 20 controls.

Many of the current neuropsychological test batteries include drawing tests which are believed to require intact conceptual, visual and action processing ability. One part of the screening test is the commonly used clock drawing test. In chapter 3, I report different types of performance deficits demonstrated by patients with left or right hemisphere damage when drawing a clock and copying a complex figure. The results led me to conclude that clock drawing may draw more on concep- tua l components of action production than spatial

components. The reverse may be t rue of pat tern copying. Distinguishing between conceptual and spatial aspects of action impairment appears to be a useful initial approach to the assessment of dyspraxia.

Relative to the domains of language and visual percep- t ion, t h e mechanisms underlying t h e control of movement have received less attention in cognitive neuropsychological research. Movement control is discussed in more detail in chapter 4 and a model of praxis is proposed. Working from this model, and assessment studies of dyspraxic patients, consequent indications for the development of a clinical assessment of dyspraxia are presented in chapter 5 .

I propose that the clinical assessment of neuropsycho- logical impairments (where such an assessment is based on a cognitive neuropsychological model) is important, in that it may allow treatment to be specif- ically directed towards impaired processing components.
