RESUMO
PURPOSE: Neurogenic orthostatic hypotension (nOH) is a frequent nonmotor feature of Parkinson's disease (PD), associated with adverse outcomes. Recently, 24-h ambulatory blood pressure monitoring (ABPM) showed good accuracy in diagnosing nOH. This study aims at evaluating the prognostic role of ABPM-hypotensive episodes in predicting PD disability milestones and mortality and comparing it to the well-defined prognostic role of bedside nOH. METHODS: Patients with PD who underwent ABPM from January 2012 to December 2014 were retrospectively enrolled and assessed for the development of falls, fractures, dementia, bed/wheelchair confinement, hospitalization, and mortality, during an up-to-10-year follow-up. Significant ABPM-hypotensive episodes were identified when greater than or equal to two episodes of systolic BP drop ≥ 15 mmHg (compared with the average 24 h) were recorded during the awakening-to-lunch period. RESULTS: A total of 99 patients (74% male, age 64.0 ± 10.1 years, and PD duration 6.4 ± 4.0 years) were enrolled. At baseline, 38.4% of patients had ABPM-hypotensive episodes and 46.5% had bedside nOH. On Kaplan-Meier analysis, patients with ABPM-hypotensive episodes showed earlier onset of falls (p = 0.001), fractures (p = 0.004), hospitalizations (p = 0.009), bed/wheelchair confinement (p = 0.032), dementia (p = 0.001), and shorter survival (8.0 versus 9.5 years; p = 0.009). At Cox regression analysis (adjusted for age, disease duration, Charlson Comorbidity Index, and Hoehn and Yahr stage) a significant association was confirmed between ABPM-hypotensive episodes and falls [odds ratio (OR) 3.626; p = 0.001), hospitalizations (OR 2.016; p = 0.038), and dementia (OR 2.926; p = 0.008), while bedside nOH was only associated with falls (OR 2.022; p = 0.039) and dementia (OR 1.908; p = 0.048). CONCLUSIONS: The presence of at least two ABPM-hypotensive episodes independently predicted the development of falls, dementia, and hospitalization, showing a stronger prognostic value than the simple bedside assessment.

INTRODUCTION: Parkinson's Disease (PD) patients with Parkin gene (PRKN) mutations show good response to subthalamic deep brain stimulation (STN-DBS). Currently, the longest follow-up available of these patients is 6 years. We report a very long-term outcome (more than 15 years) of a STN-DBS-treated patient with a compound heterozygous deletion of exons 3 and 11 of the PRKN gene. CASE REPORT: In 1993, a 39-year-old male was diagnosed with PD after the onset of resting tremor. Levodopa was started, and during the following 10 years, he reported good motor symptoms control, with only mild modification of levodopa intake and pramipexole introduction. In 2005, he developed disabling motor fluctuations and dyskinesia. In 2007, he underwent bilateral STN-DBS, with a marked improvement of motor symptoms and fluctuations during the following years. After 6 years, he reported mild motor fluctuations, improved after stimulation and treatment modifications. After 10 years he showed diphasic dyskinesias, feet dystonia, postural instability, and gambling (resolved after pramipexole discontinuation). In 2018, he developed a non-amnestic single-domain mild cognitive impairment (MCI). In 2023, after more than 15 years of STN-DBS, motor symptoms and fluctuations are still well controlled. He reports mild dysphagia, mild depression, and multiple-domain MCI. His quality of life is better than before surgery, and he still reports a subjective significant improvement from STN-DBS. CONCLUSION: Confirming the very long-term efficacy of STN-DBS in PRKN-mutated patients, our case report underlines their peculiar suitability for surgical treatment.

INTRODUCTION: Gaucher disease (GD) is classically divided into three types, based on the presence or absence of neurological signs and symptoms. However, presentation can be highly variable in adulthood, and this aspect has not been adequately addressed in the literature so far. We performed a systematic literature review to analyze the entire spectrum of neurological manifestations in adult patients previously classified as GD type I, II, or III, evaluating the role of variants in different neurological manifestations. METHODS: We searched databases for studies reporting clinical data of adult GD patients (age ≥ 18). Data extraction included GD types, GBA1 variants, age at disease onset and diagnosis, duration of GD, and age at onset and type of neurological symptoms reported. RESULTS: Among 4190 GD patients from 85 studies, 555 exhibited neurological symptoms in adulthood. The median age at evaluation was 46.8 years (IQR 26.5), age at neurological symptoms onset was 44 years (IQR 35.1), and age at GD clinical onset was 23 years (IQR 23.4). Parkinsonism, including Parkinson's disease and Lewy Body dementia, was the most reported neurological manifestation. Other symptoms and signs encompassed oculomotor abnormalities, peripheral neuropathy, seizures, myoclonus, and cerebellar, cognitive and psychiatric symptoms. The genotype N370S/N370S mostly presented with Parkinsonism and the L444P variant with severe and earlier neurological symptoms. CONCLUSION: The findings of this systematic review highlight: (1) the relevance of a comprehensive neurological assessment in GD patients, and (2) the importance of considering possible undiagnosed GD in adult patients with mild systemic symptoms presenting unexplained neurological symptoms.

BACKGROUND: Sleep disorders negatively impact quality of life in Parkinson's disease (PD), yet the role of antiparkinsonian drugs on sleep quality is still unclear. We aimed to explore the correlation between sleep dysfunction and dopaminergic therapy in a large cohort of advanced PD patients. METHODS: Patients consecutively evaluated for device-aided therapies eligibility were evaluated by means of the PD Sleep Scale (PDSS-2; score ≥ 18 indicates poor sleep quality), and the Epworth Sleepiness Scale (ESS score ≥ 10 indicates excessive daytime sleepiness-EDS). Binary logistic regression analysis, adjusting for age, sex, disease duration, motor impairment, and sleep drugs, was employed to evaluate the association between dopaminergic therapy and PDSS-2 and ESS scores. Analysis of covariance assessed differences in PDSS-2 and ESS scores between patients without DA, and between patients treated with low or high doses of DA (cut-off: DA-LEDD = 180 mg). RESULTS: In a cohort of 281 patients, 66.2% reported poor sleep quality, and 34.5% reported EDS. DA treatment demonstrated twofold lower odds of reporting relevant sleep disturbances (OR 0.498; p = 0.035), while DA-LEDD, levodopa-LEDD, total LEDD, and extended-release levodopa were not associated with disturbed sleep. EDS was not influenced by dopaminergic therapy. Patients with DA intake reported significant lower PDSS-2 total score (p = 0.027) and "motor symptoms at night" domain score (p = 0.044). Patients with higher doses of DA showed lower PDSS-2 total score (p = 0.043). CONCLUSION: Our study highlights the positive influence of DA add-on treatment on sleep quality in this group of advanced fluctuating PD patients.

BACKGROUND: Non-motor symptoms and non-motor fluctuations (NMF) in Parkinson's disease (PD) strongly affect health-related quality of life (HRQoL) and disability. The impact of deep brain stimulation (DBS) on NMF remains an area of uncertainty. The aim is to evaluate the impact of DBS on NMF, using the recently validated Non-Motor Fluctuation Assessment (NoMoFa), and to explore the correlation between NMF and motor symptoms, motor complications (MC), and HRQoL post-surgical improvement. METHODS: We prospectively evaluated consecutive patients undergoing subthalamic DBS (STN-DBS), at baseline and 6-months after surgery. Assessments included the NoMoFa questionnaire, the MDS-sponsored Unified Parkinson's Disease Rating Scale, and the 39-Item Parkinson's Disease Questionnaire. Pre- and post-surgical NoMoFa scores were compared using the Wilcoxon Signed rank-test. Linear regression analysis evaluated: a) the correlation between NoMoFa scores, motor and MC improvement, correcting for age, disease duration, and dopaminergic therapy reduction; b) the correlation between HRQoL and NMF improvement, correcting for age, disease duration, motor and MC improvement. RESULTS: Twenty patients were evaluated. Total NMF score significantly improved (44.6 %, [IQR = 18.3-100]; p = 0.022), particularly in Off condition (52.0 %, [IQR = 25.4-100]; p = 0.009); we observed strong correlation between NMF and MC improvement (Beta = 0.728; p = 0.006), mainly driven by the mitigation of unpredictable Off (Beta = 0.905; p < 0.001). Even after adjusting for potential confounders, the reduction of NMF independently correlated with increased HRQoL (Beta = 0.714; p = 0.010). CONCLUSIONS: STN-DBS demonstrated strong beneficial effect on NMF, resulting in significant improvement of HRQoL. This underlines the importance of recognizing NMF as a significant factor to be considered in the selection of patients eligible for STN-DBS.

Results: Ninety-nine patients (male 74%; age: 64.0 ± 10.1 years; PD duration: 6.4 ± 4.0 years) were enrolled. At baseline, 38.4% of patients had ABPM-hypotensive episodes and 46.5% had bedside nOH.At Kaplan-Meier analysis patients with ABPM-hypotensive episodes had an earlier onset of falls (p = 0.001), fractures (p = 0.004), hospitalizations (p = 0.009), bed/wheelchair confinement (p = 0.032), dementia (p = 0.001), and showed a shorter survival (8.0vs9.5 years; p = 0.009). At Cox regression analysis (adjusted for age, disease duration, Charlson Comorbidity Index, and H&Y stage at baseline) a significant association was confirmed between ABPM-hypotensive episodes and falls (OR:3.626; p = 0.001), hospitalizations (OR:2.016; p = 0.038), and dementia (OR:2.926; p = 0.008), while bedside nOH was only associated with falls (OR 2.022; p = 0.039) and dementia (OR:1.908; p = 0.048). Conclusion: The presence of at least two ABPM-hypotensive episodes independently predicted the development of falls, dementia, and hospitalization, showing a stronger prognostic value than the simple bedside assessment.
