Ethnic Disparities in Treatment of Chronic Pain in Individuals with Parkinson's Disease Living in the United Kingdom.

Background: Over 80% people with Parkinson's disease (PD; PwP) live with chronic pain.

Objective: Whether ethnic disparities in receipt of appropriate analgesia exist among PwP with chronic pain living in the United Kingdom (UK).

Methods: A retrospective datamining of an existing King's PD Pain Questionnaire validation study dataset enrolling 300 PwP.

Structural differences in impaired verbal fluency in essential tremor patients compared to healthy controls.

Objective: We wanted to identify differences in grey and white matter in essential tremor patients compared to controls in the non-motor domain, using the example of impaired verbal fluency.

Background: A disturbance of verbal fluency in essential tremor patients compared to healthy controls is behaviorally well described.

Methods: Voxel-based morphometry and tract-based spatial statistics were used to analyze structural differences in grey and white matter in 19 essential tremor patients compared to 23 age- and gender-matched controls.

Impact of tau and amyloid burden on glucose metabolism in Alzheimer's disease.

In a multimodal PET imaging approach, we determined the differential contribution of neurofibrillary tangles (measured with [F]AV-1451) and beta-amyloid burden (measured with [C]PiB) on degree of neurodegeneration (i.e., glucose metabolism measured with [F]FDG-PET) in patients with Alzheimer's disease.
