Clinical diagnostic criteria for dementia associated with Parkinson's disease
Clinical diagnostic criteria for probable and possible PD‐D are proposed, characterized by impairment in attention, memory, executive and visuo‐spatial functions, behavioral symptoms such as affective changes, hallucinations, and apathy are frequent.
Apathy and the functional anatomy of the prefrontal cortex-basal ganglia circuits.
The clinical signs grouped under the concept of apathy are a common feature of prefrontal and basal ganglia lesions or dysfunctions and can therefore help to improve our understanding of the

The main focus of this article is to operationalize the diagnosis of PD‐D and to propose pratical guidelines based on a two level process depending upon the clinical scenario and the expertise of the evaluator involved in the assessment.
The neural system that bridges reward and cognition in humans: An fMRI study
The study showed specific brain activation in relation with changes in both the cognitive loading and the reward associated with task performance, suggesting a balance between increasing activity in cortical cognitive areas and decreasing activity in the limbic and paralimbic structures during ongoing higher cognitive processing.
Coupled Temporal Memories in Parkinson's Disease: A Dopamine-Related Dysfunction
Patients with Parkinson's disease were studied in temporal reproduction tasks and a mutual attraction between temporal processing systems, in memory and clock stages, when dopaminergic regulation in the striatum is dysfunctional is discussed.
Rostral and caudal prefrontal contribution to creativity: a meta-analysis of functional imaging data
Functional imaging data is reviewed to suggest that several frontal and parieto-temporal regions may support cognitive processes shared by diverse creativity tasks, and that some regions may be specialized for distinct types of processes.
Apathy following subthalamic stimulation in Parkinson disease: A dopamine responsive symptom
It is suggested that apathy, which was compensated for by an enhancement of D2‐D3 receptor stimulation in PD patients with STN stimulation: (1) depends on a dopaminergic deficit in associativo‐limbic areas of the brain and (2) can be avoided if a dopamineergic agonist is administered postoperatively.
