The current paper assessed bradyphrenia, or slowed thinking, in patients with Parkinson's disease, Huntington's disease, and schizophrenia using a modified planning measure designed to maximise the demands on cognitive processing. Findings indicated normal performance in schizophrenia but prolonged thinking time in Parkinson's disease and, to a lesser degree, Huntington's disease and a relationship between thinking time and task complexity.
