RESUMO
BACKGROUND: In spite of being considered the gold-standard of care, little is known about the real-life use of in-home and multidisciplinary care in atypical parkinsonism. OBJECTIVE: Primary: Examine real-life multidisciplinary care use for Progressive Supranuclear Palsy (PSP). Secondary: a) Compare PSP care to advanced Parkinson's disease (APD) care; (b) Explore demographic and clinical variables associated with care needs in both groups. METHODS: A cross-sectional multicenter observational study enrolled 129 PSP patients and 65 APD patients (Hoehn and Yahr ≥3), matched for sex and age. Univariate and multivariate regression analysis were performed. RESULTS: Over the previous year, 40 % of PSP patients did not encounter a physical therapist, while only one-third met a speech and language therapist and 5 % an occupational therapist. More than 20 % received in-home care and 32 % needed home structural changes. Compared to APD, PSP patients required more day-time, night-time and home structural changes. When considering both PSP and APD in multivariate analysis, reduced functional autonomy and living without a family caregiver were both related to day-time home assistance and to the need of at least one home care service. A PSP diagnosis compared to APD was a risk factor for having at least four multidisciplinary visits in a year. Finally, PSP diagnosis and being from the Northern Italy were significantly related with home structural changes. CONCLUSIONS: There's a significant gap in providing multidisciplinary care for PSP patients. Our findings emphasize the need for a shared, integrated care plan at a national level for patients with atypical parkinsonism.

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.
RESUMO
Background: Gait issues, including reduced speed, stride length and freezing of gait (FoG), are disabling in advanced phases of Parkinson's disease (PD), and their treatment is challenging. Levodopa/carbidopa intestinal gel (LCIG) can improve these symptoms in PD patients with suboptimal control of motor fluctuations, but it is unclear if continuous dopaminergic stimulation can further improve gait issues, independently from reducing Off-time. Objective: To analyze before (T0) and after 3 (T1) and 6 (T2) months of LCIG initiation: a) the objective improvement of gait and balance; b) the improvement of FoG severity; c) the improvement of motor complications and their correlation with changes in gait parameters and FoG severity. Methods: This prospective, longitudinal 6-months study analyzed quantitative gait parameters using wearable inertial sensors, FoG with the New Freezing of Gait Questionnaire (NFoG-Q), and motor complications, as per the MDS-UPDRS part IV scores. Results: Gait speed and stride length increased and duration of Timed up and Go and of sit-to-stand transition was significantly reduced comparing T0 with T2, but not between T0-T1. NFoG-Q score decreased significantly from 19.3±4.6 (T0) to 11.8±7.9 (T1) and 8.4±7.6 (T2) (T1-T0 pâ=â0.018; T2-T0 pâ<â0.001). Improvement of MDS-UPDRS-IV (T0-T2, pâ=â0.002, T0-T1 pâ=â0.024) was not correlated with improvement of gait parameters and NFoG-Q from T0 to T2. LEDD did not change significantly after LCIG initiation. Conclusion: Continuous dopaminergic stimulation provided by LCIG infusion progressively ameliorates gait and alleviates FoG in PD patients over time, independently from improvement of motor fluctuations and without increase of daily dosage of dopaminergic therapy.

BACKGROUND: Dyskinesias and freezing of gait are episodic disorders in Parkinson's disease, characterized by a fluctuating and unpredictable nature. This cross-sectional study aims to objectively monitor Parkinsonian patients experiencing dyskinesias and/or freezing of gait during activities of daily living and assess possible changes in spatiotemporal gait parameters. METHODS: Seventy-one patients with Parkinson's disease (40 with dyskinesias and 33 with freezing of gait) were continuously monitored at home for a minimum of 5 days using a single wearable sensor. Dedicated machine-learning algorithms were used to categorize patients based on the occurrence of dyskinesias and freezing of gait. Additionally, specific spatiotemporal gait parameters were compared among patients with and without dyskinesias and/or freezing of gait. RESULTS: The wearable sensor algorithms accurately classified patients with and without dyskinesias as well as those with and without freezing of gait based on the recorded dyskinesias and freezing of gait episodes. Standard spatiotemporal gait parameters did not differ significantly between patients with and without dyskinesias or freezing of gait. Both the time spent with dyskinesias and the number of freezing of gait episodes positively correlated with the disease severity and medication dosage. CONCLUSIONS: A single inertial wearable sensor shows promise in monitoring complex, episodic movement patterns, such as dyskinesias and freezing of gait, during daily activities. This approach may help implement targeted therapeutic and preventive strategies for Parkinson's disease.
RESUMO
INTRODUCTION: CACNA1A gene variants are correlated with different disorders, including episodic ataxia type 2, spinocerebellar ataxia type 6, and familial hemiplegic migraine type 1. Despite dystonia not being a typical manifestation of CACNA1A variants, there are reports indicating a link between this gene mutation and dystonic features. METHODS: We report the case of a patient with a novel missense variant of the CACNA1A gene presenting headache, head and arm tremor, dystonia, episodic painful focal dystonic attacks, and unexplained falls. RESULTS: A 57-year-old woman presented with a history of neck dystonia, head and arm tremor, and headaches since age 15. In 2017, she progressively developed dystonic tremor of the head and arms with an unremarkable brain MRI. In 2018 she experienced worsening of tremor and developed painful dystonic attacks, resistant to treatments including clonazepam, trihexyphenidyl, baclofen, and levodopa/benserazide. Botulinum toxin injections for neck dystonia provided limited benefit. The next-generation sequencing exam revealed a CACNA1A gene missense variant (NM_023035.2:c.1630C > T; p.Arg544Trp). In 2021 we observed a worsening of dystonia, accompanied by weight loss, mood changes, and unexplained falls. Deep brain stimulation was considered but ruled out due to cortical atrophy and mild cognitive deficits revealed by the neuropsychological examination. DISCUSSION: Only a few studies reported dystonia as part of the clinical features in carriers of CACNA1A mutations. This case points out the relevance of a need to expand the literature on voltage-dependent P/Q-type Ca2 + channels' role in dystonia's pathogenesis and stresses the complex phenotype-genotype presentation of CACNA1A mutation.

Axial postural abnormalities (APAs), characterized by their frequency, disabling nature, and resistance to pharmacological treatments, significantly impact Parkinson's disease and atypical Parkinsonism patients. Despite advancements in diagnosing, assessing, and understanding their pathophysiology, managing these complications remains a significant challenge. Often underestimated by healthcare professionals, these disturbances can exacerbate disability. This systematic review assesses botulinum toxin treatments' effectiveness, alone and with rehabilitation, in addressing APAs in Parkinson's disease, utilizing MEDLINE (PubMed), Web of Science, and SCOPUS databases for source material. Of the 1087 records retrieved, 16 met the selection criteria. Most research has focused on botulinum toxin (BoNT) as the primary treatment for camptocormia and Pisa syndrome, utilizing mostly observational methods. Despite dose and injection site variations, a common strategy was using electromyography-guided injections, occasionally enhanced with ultrasound. Patients with Pisa syndrome notably saw consistent improvements in APAs and pain. However, studies on the combined effects of botulinum toxin and rehabilitation are limited, and antecollis is significantly under-researched. These findings recommend precise BoNT injections into hyperactive muscles in well-selected patients by skilled clinicians, avoiding compensatory muscles, and underscore the necessity of early rehabilitation. Rehabilitation is crucial in a multidisciplinary approach to managing APAs, highlighting the importance of a multidisciplinary team of experts.

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: Axial postural abnormalities (PA) are invalidating symptoms of Parkinson's disease (PD). Risk factors for PA are unknown. OBJECTIVES: We sought to evaluate PA incidence and risk factors over the first 4-6 years of PD. METHODS: We included 441 PD patients from the Parkinson's Progression Markers Initiative (PPMI) cohort with data at diagnosis and after 4-year follow-up. PA was defined according to a posture item ≥ 2 at the Movement Disorder Society-sponsored-revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) in Off therapeutic condition. The Kruskal-Wallis test was used to compare characteristics of patients without PA ('no-PA'), with PA at disease onset ('baseline-PA'), and PA developed during follow-up ('develop-PA'). To identify predictors of PA development, univariate and multivariate Cox regression analyses were performed considering demographic, clinical and therapeutic variables. RESULTS: 10.9% of patients showed PA at baseline and 23.7% developed PA within the first 4-6 years since diagnosis. Older age, malignant phenotype, higher MDS-UPDRS part III, Hoehn & Yahr, and dysautonomia (SCOPA-AUT) score, and lower levels of physical activity were predictors of PA development at the univariate analysis. Older age (Hazard ratio [HR] per year: 1.041) and higher MDS-UPDRS part III score (HR per point: 1.035) survived as PA development predictors in the multivariate analysis. CONCLUSIONS: PPMI cohort data show that > 30% of PD patients present PA within the first 4-6 years of disease. Older age at onset and higher motor burden are associated with a higher risk for PA development. The protective role of physical activity merits to be further investigated.

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: Several earlier studies showed a female predominance in idiopathic adult-onset dystonia (IAOD) affecting the craniocervical area and a male preponderance in limb dystonia. However, sex-related differences may result from bias inherent to study design. Moreover, information is lacking on whether sex-related differences exist in expressing other dystonia-associated features and dystonia spread. OBJECTIVE: To provide accurate information on the relationship between sex differences, motor phenomenology, dystonia-associated features and the natural history of IAOD. METHODS: Data of 1701 patients with IAOD from the Italian Dystonia Registry were analysed. RESULTS: Women predominated over men in blepharospasm, oromandibular, laryngeal and cervical dystonia; the sex ratio was reversed in task-specific upper limb dystonia; and no clear sex difference emerged in non-task-specific upper limb dystonia and lower limb dystonia. This pattern was present at disease onset and the last examination. Women and men did not significantly differ for several dystonia-associated features and tendency to spread. In women and men, the absolute number of individuals who developed dystonia tended to increase from 20 to 60 years and then declined. However, when we stratified by site of dystonia onset, different patterns of female-to-male ratio over time could be observed in the various forms of dystonia. CONCLUSIONS: Our findings provide novel evidence on sex as a key mediator of IAOD phenotype at disease onset. Age-related sexual dimorphism may result from the varying exposures to specific age-related and sex-related environmental risk factors interacting in a complex manner with biological factors such as hormonal sex factors.
