The Value of Regional Cerebral Blood Flow Measurements in Neuropsychological Rehabilitation
Jarl Risberg and Lise Randrup Jensen
Measurement of the regional cerebral blood flow (rCBF) is one way of imaging the function of the cerebral cortex. Such measurements might be helpful in the evaluation of the consequences of brain damage for the function of the brain, as well as for elucidating how different rehabilitation methods utilize its preserved potentials. In this chapter, two illustrative cases are described in which the rCBF measurements helped to understand the functional consequences of the brain disorder, as well as helped to supply information of value for the rehabilitation process.
One of the major issues in aphasia rehabilitation concerns theory
and method in language therapy: How do we diagnose and describe
specific aphasic disturbances for rehabilitation purposes by reference
to models of brain-language functioning, and what is the rationale
behind specific methods employed in aphasia rehabilitation? Modern
methods for imaging of the function of the brain might be helpful
tools in the elucidation of these issues. In numerous investigations,
rCBF has been shown to be a sensitive indicator of brain function,
and several methods of measurement are available. Concerning
diagnosis, rCBF may be important for inferences of brain-language
relationships based on aphasic symptoms by virtue of providing
information about the functional consequences of a structural lesion.
For example, localization of linguistic functions to subcortical areas
