FRACTIONATION OF THE FRONTAL-LOBE SYNDROME

It is argued that the severity of the cognitive problems seen following frontal damage may reflect the number of different individual processes affected rather than just overall severity of impairment in one core process. A number of recent studies are described which seem to suggest that a fractionation of the frontal lobe syndrome may be possible. However the considerable methodological problems involved are discussed, and it is argued that approaches not commonly used in neuropsychology may be required.
