AI Article Synopsis

  • This study focused on understanding the cognitive and behavioral characteristics of Parkinson's disease patients who experience central parkinsonian pain, a specific type of pain associated with the disease.
  • Out of 260 patients, 68% reported pain, with 22% having central parkinsonian pain; these patients generally showed better cognitive performance on certain tests but exhibited more compulsive behaviors and higher smoking rates compared to those without pain.
  • The findings suggest that patients with central parkinsonian pain may have a unique profile within Parkinson's disease, characterized by preserved cognitive function alongside increased vulnerability to compulsive or addictive behaviors.

Article Abstract

Introduction: Pain is a major nonmotor symptom of Parkinson's disease (PD), and central parkinsonian pain is the core feature of the putative Park pain subtype of PD. This study aimed to explore the cognitive and behavioral profile of PD patients with central parkinsonian pain. . A structured interview was used to identify and characterize pain in a cohort of 260 consecutive PD patients. The Ford classification of pain was applied. The Dementia Rating Scale-2 (DRS-2) and the Impulse Control Disorders in Parkinson's Disease Short Form (QUIP-S) were administered, and patients' smoking habits were recorded. The Unified Parkinson's Disease Rating Scale (UPDRS) was used to assess motor and nonmotor symptoms in and conditions.

Results: One hundred and eighty-eight patients (68%) reported pain; and in 41 (22%) of them, the pain was classified as central parkinsonian pain. PD patients with central parkinsonian pain had better cognitive performance in DRS-2 Initiation/Perseveration and Conceptualization subscales but reported more other compulsive behaviors (e.g., hobbyism, punding, and walkabout) and had more current smoking habits than those without pain or with non-central parkinsonian pain. Multiple logistic regression analyses revealed that the DRS-2 Conceptualization subscale, other compulsive behaviors, and smoking habits remained statistically associated with central parkinsonian pain even when other significant covariates were considered. Only patients with pain, regardless of type, had a gambling disorder. . The study results provide further evidence that pain revealed that patients with central parkinsonian pain are more likely to present compulsive or addictive behaviors, despite having more preserved cognitive performance. Patients with central parkinsonian pain appear to have a distinct phenotype of PD.

Article Synopsis
  • The study investigates the high prevalence of pain in Parkinson's disease (PD) patients, with 80.6% reporting pain, indicating its significant impact on quality of life.
  • It distinguishes between neuropathic pain (NP) and musculoskeletal pain, finding that longer disease duration predicts NP and that females experience more musculoskeletal pain.
  • The research highlights the correlation between anxiety and central parkinsonian pain and suggests further exploration of amantadine's potential benefits in managing pain, emphasizing the need for personalized treatment approaches in PD.

Article Synopsis
  • Spinal cord stimulation is a minimally invasive surgery used to treat chronic pain, and has recently gained attention for helping patients with advanced Parkinson's disease and atypical parkinsonism.
  • Recent studies show it can improve gait issues, particularly the freezing of gait, which is a common and debilitating symptom in these conditions.
  • This review highlights the effectiveness of chronic epidural spinal cord stimulation in reducing locomotor problems, especially in patients who don’t respond well to traditional therapies.

Background: Delirium is a postoperative complication that may occur in older patients. This study aimed to investigate the incidence of postoperative delirium and its risk factors in patients who had undergone total hip arthroplasty (THA) or total knee arthroplasty (TKA). Few reports have addressed the occurrence of delirium when different methods of pain control are used following total joint arthroplasty, and, therefore, whether its incidence varied depending on differences in pain control was investigated.

Article Synopsis
  • * A study involving 79 patients revealed high percentages of pain in MSA (73.9%), PSP (50.0%), DIP (67.9%), and VP (66.7%), but found no significant differences in sensory discrimination thresholds (SDT) between those with and without pain.
  • * The research concluded that the scaling function did not play a significant role in the development of pain among the different parkinsonian disorders studied.

Article Synopsis
  • GPR88 is an orphan G protein-coupled receptor primarily found in the striatum, and its function is not well understood despite changes in its expression seen in Parkinson's disease models.
  • GPR88 was found to interact with the kappa-opioid receptor (KOR), and this interaction inhibits KOR-mediated signaling, as evidenced by experiments showing that GPR88 can modulate effects of KOR agonists in both cultured cells and primary striatal neurons.
  • The GPR88-KOR complexes were more common in specific neurons related to dopamine pathways, suggesting that understanding their relationship could have implications for conditions like neuropathic pain, Parkinson's disease, and neuropsychiatric disorders.
