Modified Six Elements Test: Earlier diagnosis of the correlation between motor and executive dysfunction in Parkinson's disease without dementia

In patients with Parkinson's disease, executive deficits are known to correlate with motor dysfunctions, such as gait and postural instability. However executive deficits are sometimes difficult to detect using common frontal assessment batteries. Behavioral Assessment of Dysexecutive Syndrome includes six subtests to evaluate different aspects of executive function required in daily life. Among these the Modified Six Elements Test examines higher levels of executive function with regard to prospective memory and organization of behavior.
