The thickness of posterior cortical areas is related to executive dysfunction in Alzheimer's disease.

Objective: To establish whether alterations of brain structures in Alzheimer's disease are associated with executive dysfunction.

Methods: Nineteen patients with Alzheimer's disease and 22 older control subjects underwent a comprehensive evaluation. The clock drawing test, digit span test, executive motor function test, Behavioral Assessment of the Dysexecutive Syndrome battery (Rule Shift Cards test), and Stroop test were used to evaluate executive dysfunction.

Voxel-based morphometry findings in Alzheimer's disease: neuropsychiatric symptoms and disability correlations - preliminary results.

Introduction: The role of structural brain changes and their correlations with neuropsychiatric symptoms and disability in Alzheimer's disease are still poorly understood.

Objective: To establish whether structural changes in grey matter volume in patients with mild Alzheimer's disease are associated with neuropsychiatric symptoms and disability

Methods: Nineteen Alzheimer's disease patients (9 females; total mean age =75.2 y old +4.
