| Abstract |
Delusions in Parkinson's disease (PD) are thought to be associated with disease progression and cognitive impairment. However, this symptom description is not consistent in the literature and there is a suggestion that different subgroups of psychotic patients occur in PD, which we aimed to clarify. Case reports were identified through a systematic search of databases (PUBMED, EMBASE, PsychInfo). Cases with isolated delusions were compared to those with both delusions and hallucinations. We identified 184 cases of delusions in PD. Delusions were primarily paranoid in nature (83%) and isolated in 50%. Those with isolated delusions had an earlier onset of PD (46 years vs 55 years), higher rates of impulse control disorders (40.2 vs 10.3%), dopamine dysregulation (29.9 vs 11.3%) and lower rates of cognitive impairment (8.0 vs 26.8%). There is unexpected heterogeneity amongst cases of delusional psychosis, that cannot adequately be explained by existing models of PD psychosis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 17. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 April 2023.
All research outputs
#1,929,024
of 23,578,918 outputs
Outputs from Neuropsychology Review
#57
of 468 outputs
Outputs of similar age
#41,392
of 331,882 outputs
Outputs of similar age from Neuropsychology Review
#1
of 4 outputs
Altmetric has tracked 23,578,918 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 91st percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 468 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 11.8. This one has done well, scoring higher than 87% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 331,882 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 87% of its contemporaries.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
