The association between care needs level (CNL) and functional outcomes after diagnosis in older patients with Parkinson’s disease (PD) is unclear.
Methods
Using health insurance claims and the Japanese Long-Term Care (LTC) data from 12 municipalities in Japan, PD patients aged ≥ 65 years old were identified between April 2014 and March 2022. CNL was classified as no care needed (NCN), support level (SL), CNL1 (low level), CNL2-3, and CNL4-5 (fully dependent) based on the total estimated daily care hours as defined by the national standard criteria. The primary outcomes were changes in CNL and all-cause death one year after PD diagnosis by baseline CNL at diagnosis.
Results
Of the 11,270 PD patients, 39.8% had NCN, 27.6% SL&CNL1, 18.8% CNL2-3, and13.9% CNL4-5 at PD diagnosis. One-year after diagnosis, there were NCN 28.2%, SL&CNL1 24.9%, CNL2-3 19.2%, CNL4-5 17.6% (i.e., 61.7% required care need), and all-cause death 10.1%. Compared with NCN patients at diagnosis, patients with SL&CNL1, CNL2-3, and CNL4-5 had an increased risk of all-cause death one-year after diagnosis (adjusted hazard ratio [95% confidence interval]: 1.58 [1.29–1.93], 2.83 [2.32–3.46], and 5.80 [4.76–7.06]), assessed by using Cox proportional hazard models.
Conclusions
Baseline CNL in older Japanese patients was associated with all-cause death even one-year after PD diagnosis, and high CNL was associated with a high risk of all-cause death.

Background
The most common movement disorder and neurodegenerative disorder that progresses over time, Parkinson’s disease, has both motor and nonmotor symptoms. Asia is home to half of the world’s elderly population, and Parkinson’s disease is a common condition in this demographic.
Objectives
We aimed to estimate the pooled prevalence of nonmotor symptoms among Parkinson’s disease patients in South Asia based on the available literature.
Methods
The study protocol was registered on PROSPERO with reference number CRD42024579956. Databases were searched for observational studies from 2000 to 2024 in English that have assessed the prevalence of nonmotor symptoms among Parkinson’s disease patients in South Asia via validated tools. High-quality studies were included after quality assessment. A random-effects model was used to calculate the pooled prevalence with a 95 % confidence interval.
Results
Among the 50 articles (4931 participants) included in the review, 9 (862 participants) used the Nonmotor Symptoms Questionnaire, 9 (803 participants) used the Nonmotor Symptoms Scale, 2 (171 participants) used both, and the remaining 30 (3095 participants) used other validated tools to assess nonmotor symptoms in South Asian patients with Parkinson’s disease. The prevalence of nonmotor symptoms was high, with nocturia being the most prevalent. Psychological symptoms were frequently explained via other tools.
Conclusions
Our research is among the few clinical accounts in the literature of the prevalence of nonmotor stmptoms in South Asian Parkinson’s disease patients. Although the heterogeneity of the results could not be fully explained, our study could significantly enhance the understanding of symptoms, leading to more tailored therapeutic and diagnostic strategies.

Background
Cognitive impairment is a major non-motor complication of Parkinson’s disease (PD). GBA mutations are associated with an increased risk, with PD-GBA+ patients typically showing earlier disease onset and faster cognitive decline. However, the specific cognitive phenotype of these patients remains unclear.
Aim
To provide a detailed neuropsychological profile of PD-GBA+ patients compared to PD-GBA− patients.
Methods
Data from 18 PD-GBA+ and 68 PD-GBA− patients were retrospectively analyzed. All participants underwent comprehensive neurological evaluations of motor and non-motor symptoms, along with a Level II neuropsychological assessment based on the MDS criteria for mild cognitive impairment (MCI). Patients with dementia were excluded.
Results
PD-GBA+ patients showed significantly lower cognitive performance, particularly on the RAVLT immediate recall (RAVLT-IR, p < 0.001) and delayed recall (RAVLT-DR, p = 0.002). All PD-GBA+ patients exhibited an amnestic multi-domain MCI phenotype. In contrast, the PD-GBA− group predominantly showed a non-amnestic single-domain MCI, characterized by a dysexecutive profile. Additionally, PD-GBA+ patients had a higher prevalence of freezing of gait (p < 0.001), right-sided motor symptom lateralization (p = 0.011), and REM sleep behavior disorder (p = 0.006).
Conclusions
PD-GBA+ patients exhibit a distinctive cognitive phenotype, already evident in the early stages of the disease. These results highlight the added value of Level II neuropsychological assessment in accurately characterizing the clinical phenotype and identifying patients at higher risk of developing dementia. Early cognitive profiling may thus contribute to more targeted monitoring and personalized therapeutic strategies.
认知障碍是帕金森病(PD)的主要非运动并发症。GBA突变与风险增加有关,PD-GBA+患者通常表现出更早的疾病发作和更快的认知能力下降。然而,这些患者的具体认知表型尚不清楚。目的提供PD-GBA+患者与PD-GBA -患者的详细神经心理学资料。方法回顾性分析18例PD-GBA+和68例PD-GBA -患者的资料。所有参与者都接受了运动和非运动症状的综合神经学评估,以及基于MDS轻度认知障碍(MCI)标准的II级神经心理学评估。痴呆患者排除在外。结果spd - gba +患者的认知表现明显下降,尤其是在RAVLT即时回忆(RAVLT- ir, p <;延迟回忆(RAVLT-DR, p = 0.002)。所有PD-GBA+患者均表现为遗忘型多域MCI表型。相比之下,PD-GBA组主要表现为非遗忘的单域MCI,其特征是执行障碍。此外,PD-GBA+患者步态冻结的发生率更高(p <;0.001)、右侧运动症状偏侧化(p = 0.011)和REM睡眠行为障碍(p = 0.006)。结论spd - gba +患者表现出独特的认知表型,在疾病的早期阶段已经很明显。这些结果突出了二级神经心理学评估在准确表征临床表型和识别痴呆高风险患者方面的附加价值。因此,早期认知分析可能有助于更有针对性的监测和个性化的治疗策略。

Some patients presenting with Parkinson’s disease (PD)-like features do not exhibit dopaminergic denervation, complicating clinical categorization. This case report describes a patient with a long-standing upper limb action tremor accompanied by parkinsonian signs, but without evidence of dopaminergic denervation, followed over an extended period of ten years. The case highlights the diagnostic challenges and underscores the importance of longitudinal observation in such atypical presentations.
A 76-year-old man with tremor and parkinsonian features was followed for ten years with clinical observation, video recordings, kinematic movement analysis, and structural and functional neuroimaging, including DaT-SPECT.
Clinical and kinematic evaluations revealed asymmetric upper limb action tremor, inconstant rest tremor, bradykinesia with sequence effect, re-emergent tremor, and progressive motor symptoms. Over time, tremor extended to cranial regions, and mild dystonic postures emerged. Structural neuroimaging ruled out secondary causes, and DaT-SPECT remained negative despite symptom progression. Dopaminergic therapy was ineffective, while propranolol and clonazepam provided partial relief.
This case highlights that parkinsonian motor features − such as re-emergent tremor and bradykinesia with sequence effect − can manifest and progress over time in patients with tremor, even in the absence of dopaminergic denervation. These findings underscore the need for further research into the role of the dopaminergic system in trembling patients. Moreover, they emphasize the importance of long-term follow-up and the integration of biomarkers to enhance the characterization and diagnostic accuracy of tremor syndromes.

Working Alliance (WA) significantly influences therapeutic success in psychotherapy or rehabilitation for musculoskeletal problems. The perception of WA often differs between patients and therapists. However, little is known about WA in patients with Parkinson’s disease (PD) and its relationship with clinical outcomes following physical rehabilitation. This study aimed to examine the differences in WA between patients and physical therapists in the early phase of a physical rehabilitation program and explore their relationships with improvements in gait-related assessments.
Methods
Twenty-one patients with PD who participated in the Lee Silverman Voice Treatment BIG program were included. Gait-related assessments, which included gait speed at 10-meter walking test (10-MWT) and timed up & go, were conducted before and after the program. WA was assessed using Working Alliance Inventory (WAI) for both patients and therapists after the completion of the fifth session. The difference between patient- and therapist-rated WAI was analyzed using an unpaired t-test. Correlational analyses between both patient- and therapist-rated WAI scores and improvement rates in gait-related assessments were also performed.
Results
Patients rated WAI scores significantly higher than therapists. Only patient-rated WAI scores were correlated with improvement rates in gait speed on 10-MWT, while therapist-rated WAI showed no significant correlation.
Conclusion
The results suggest patients with PD perceived WA higher than therapists in the early phase of rehabilitation, and patients’ perceptions may influence functional improvements in rehabilitation.

Introduction
heterozygous mutations in the glucocerebrosidase gene (GBA1), encoding the lysosomal enzyme β-glucocerebrosidase (GCase) are the most common genetic risk factor for Parkinson’s disease (PD). To assess the frequency of GBA1 variants related to PD in a cohort of Tuscany patients and to determine the link between GBA1 variants and motor and non-motor clinical features in PD.
Methods
We screened GCase enzyme activity on Dried Blood Spot using tandem mass spectrometry (LC-MS/MS) and performed sequencing analysis on entire cohort of PD patients by Next Generation Sequencing (NGS) technology. Variants were confirmed with Sanger method.
Results
among the 252 PD patients, we detected reduced GCase activity (≤5 μmol/h/L) in 78 (31%). NGS analysis identified 22 carriers of GBA1 variants (8.7%) in whom 14 carried common GBA1 variants currently known to be related to PD (Leu444Pro, Asn370Ser, Glu326Lys, Thr369Met and Asp409His). PD patients who were heterozygous carriers of pathogenic GBA1 variants presented with earlier onset of PD, faster disease progression and a more frequent non-motor symptoms compared to the remaining PD patients without GBA1 mutations.
Conclusions
8.7% of the 252 PD patients carried GBA1 variants at a heterozygous level, and their clinical presentation and progression were more severe compared to other patients within our cohort.

Introduction
Recombinant alleles are responsible for a large part of Gaucher disease (GD) causing alterations. This is because GBA1, the gene involved in GD, has a 96 % homologous pseudogene, GBAP1, at a 1.6kb distance. GBA1 gene variants are also the most common molecular alteration among Parkinson’s Disease (PD) patients, even in heterozygosity. The most common GD causing recombinant allele is RecNciI (which comprises three single nucleotide variants: p.L483P, p.A495P and p.Val499=). Every time this GBA1 recombinant allele is formed by an unequal crossing over event, another allele is formed with a copy number gain, i.e., a triplicate copy where GBA1 and GBAP1 are preserved, and a third intermediate copy is formed with its sequence starting at GBAP1 and then reverting to GBA1 after the recombination point (called here TRIP-SV).
Methods
Two cohorts were screened for the mid part of the TRIP-SV in PD patients using a specific amplification method. One cohort was formed by 65 early onset PD patients and the other with 100 idiopathic PD patients.
Results
In each cohort one patient carrying the TRIP-SV was detected. Sanger sequencing confirmed the expected sequence of the TRIP-SV.
Conclusion
Our findings indicate that it is mandatory that groups analyzing the GBA1 gene searching for molecular causation of PD investigate the presence of this SV encompassing the GBA1/GBAP1 region, which pathogenicity deserves further studies.

Purpose
This study aimed to explore the effects of motor impairments on different sides of the body at early onset in relation to voice acoustic performance in patients with Parkinson’s disease.
Materials and methods
Participants were classified based on which side (left or right) experienced motor impairments first, as well as the stage (early or late) of the disease. Hoehn-Yahr stages one and two were categorized as early-stage, while stages three and four were categorized as late-stage. Participants were divided into four groups: Group A, left-side early-stage conditions; Group B, left-side late-stage conditions; Group C, right-side early-stage conditions; Group D, right-side late-stage conditions. Participants performed three recording tasks that involved sustained phonation of the vowels/a/,/i/, and/u/. The study analyzed four acoustic parameters: Maximum Phonation Time (MPT), jitter, shimmer, and vF0.
Results
An Analysis of Variance revealed that for the acoustic parameters of /a/vF0 and /a/jitter, Group B performed significantly worse than Group A (p < 0.05). No significant differences were found in the other acoustic parameters or in MPT voice performance across the four groups.
Conclusions
The side of motor impairments at early onset is correlated with the severity of voice disorders. Notably, when impairments occur on the left side, the resulting voice disorders become more pronounced as the disease progresses.
