NoMoFa as a new tool to evaluate the impact of deep brain stimulation on non-motor fluctuations: A new perspective. Parkinsonism Relat Disord 2024; 126:107073. [PMID: 39067322 DOI: 10.1016/j.parkreldis.2024.107073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 07/19/2024] [Accepted: 07/22/2024] [Indexed: 07/30/2024]
Abstract
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.

Abstract
Background Motor and non-motor fluctuations adversely impact quality of life in Parkinson's disease (PD). Dysautonomia, a feature frequently associated with PD and a possible adverse effect of dopaminergic therapy, may be comorbid with fluctuations. Objectives We sought to evaluate the effect of dysautonomia on motor and non-motor fluctuations in PD. Methods Two hundred subjects with PD were evaluated in both "on" and "off" dopamine states to assess changes in symptoms related to dopaminergic fluctuations. Multivariable logistic regression was performed to assess the association of dysautonomia with motor, cognitive, and psychiatric worsening from ON to OFF states with adjustment for disease duration, levodopa equivalent daily dosage (LEDD), and dopamine agonist LEDD. Results Subjects with dysautonomia had greater odds of clinically meaningful change in motor features (OR 3.0), cognition (OR 3.4) and anxiety (OR 4.3) compared to those without dysautonomia. Conclusions Dysautonomia may be a contributory mechanism behind fluctuations in PD. The exact nature of this relationship deserves further evaluation.

Abstract
BACKGROUND Although research into Parkinson's disease (PD) subtypes and outcome predictions has continued to advance, recommendations for using outcome prediction to guide current treatment decisions remain sparse. OBJECTIVES To provide expert opinion-based recommendations for individually tailored PD symptomatic treatment based on knowledge of risk prediction and subtypes. METHODS Using a modified Delphi approach, members of the Movement Disorders Society (MDS) Task Force on PD subtypes generated a series of general recommendations around the question: "Using what you know about genetic/biological/clinical subtypes (or any individual-level predictors of outcome), what advice would you give for selecting symptomatic treatments for an individual patient now, based on what their subtype or individual characteristics predict about their future disease course?" After four iterations and revisions, those recommendations with over 75% endorsement were adopted. RESULTS A total of 19 recommendations were endorsed by a group of 13 panelists. The recommendations primarily centered around two themes: (1) incorporating future risk of cognitive impairment into current treatment plans; and (2) identifying future symptom clusters that might be forestalled with a single medication. CONCLUSIONS These recommendations provide clinicians with a framework for integrating future outcomes into patient-specific treatment choices. They are not prescriptive guidelines, but adaptable suggestions, which should be tailored to each individual. They are to be considered as a first step of a process that will continue to evolve as additional stakeholders provide new insights and as new information becomes available. As individualized risk prediction advances, the path to better tailored treatment regimens will become clearer.

Abstract
The effects of subthalamic nucleus deep brain stimulation (STN-DBS) on anxiety in Parkinson's disease (PD) are understudied. We identified clinical predictors of STN-DBS effects on anxiety in this study. In this prospective, open-label, multicentre study, we assessed patients with anxiety undergoing STN-DBS for PD preoperatively and at 6-month follow-up postoperatively. We assessed the Hospital Anxiety and Depression Scale (HADS-anxiety and depression subscales), Unified PD Rating Scale-motor examination, Scales for Outcomes in PD-motor (SCOPA-M)-activities of daily living (ADL) and -motor complications, Non-Motor Symptom Scale (NMSS), PDQuestionnaire-8 (PDQ-8), and levodopa-equivalent daily dose. We tested changes at follow-up with Wilcoxon signed-rank test and corrected for multiple comparisons (Bonferroni method). We identified patients with a clinically relevant anxiety improvement of anxiety based on a designated threshold of ½ standard deviation of baseline HADS-anxiety. Moreover, we investigated predictors of HADS-anxiety changes with correlations and linear regressions. We included 50 patients with clinically relevant baseline anxiety (i.e., HADS-anxiety ≥ 8) aged 63.1 years ± 8.3 with 10.4 years ± 4.5 PD duration. HADS-anxiety improved significantly at 6-month follow-up as 80% of our cohort experienced clinically relevant anxiety improvement. In predictor analyses, worse baseline SCOPA-ADL and NMSS-urinary domain were associated with greater HADS-anxiety improvements. HADS-anxiety and PDQ-8 changes correlated moderately. Worse preoperative ADL and urinary symptoms predicted favourable postoperative anxiety outcome, which in turn was directly proportionate to greater QoL improvement. This study highlights the importance of detailed anxiety assessments alongside other non-motor and motor symptoms when advising and monitoring patients undergoing STN-DBS for PD.

Abstract
BACKGROUND PD causes striatal dopaminergic denervation in a posterior/dorsal to anterior/ventral gradient, leaving motor and associative cortico-striato-pallido-thalamic loops differentially susceptible to hyperdopaminergic effects with treatment. As the choice and titration of symptomatic PD medications are guided primarily by motor symptoms, it is important to understand their cognitive implications. OBJECTIVE To investigate the effects of acute dopaminergic medication administration on executive function in Parkinson's disease (PD). METHODS Participants with idiopathic PD were administered the oral Symbol Digit Modalities Test (SDMT; n = 181) and the Stroop test (n = 172) in the off-medication and "best on" medication states. ANCOVA was used to test for differences between off-medication and on-medication scores corrected for age and years of education. RESULTS After administration of symptomatic medications, scores worsened on the SDMT (F = 11.70, P < 0.001, d = -0.13), improved on the Stroop color (F = 26.89, P < 0.001, d = 0.184), word (F = 6.25, P = 0.013, d = 0.09), and color-word (F = 13.22, P < 0.001, d = 0.16) test components, and the Stroop difference and ratio-based interference scores did not significantly change. Longer disease duration correlated with lower scores on the SDMT, Stroop color, word, and color-word scores; however, longer disease duration and higher levodopa-equivalents correlated with higher Stroop difference-based interference scores. CONCLUSIONS Symptomatic medication differentially affects performance on two cognitive tests in PD. After acute treatment, core Stroop measures improved, Stroop interference was unchanged, and SDMT performance worsened, likely reflecting complex changes in processing speed and executive function related to acute treatment. When considering motor symptom therapies in PD, an individual's cognitive demands and expectations, especially regarding executive function, should be considered.

Abstract
BACKGROUND Anxiety is one of the most common but often overlooked mood-related nonmotor symptoms in people with Parkinson's disease (PD). To improve the well-being of people with PD, it is important to understand the impact of anxiety in PD, especially its association with depressive and motor symptoms and its impact on health-related quality of life (HRQoL). METHODS 91 people with PD were assessed between June 2017 and June 2018. Anxiety was measured using the Geriatric Anxiety Scale (GAS) and its cognitive, somatic, and affective subscales. HRQoL was assessed using the Parkinson's Disease Questionnaire 39 (PDQ-39). Moreover, sociodemographic information, depressive symptoms, cognition, motor and nonmotor symptoms were assessed. Descriptive statistics, regression analyses, and path analyses were performed to understand predictors of anxiety and its influence on HRQoL. RESULTS Of the 91 people with PD, 35 (38.5%) experienced anxiety. Anxiety symptoms in these individuals primarily manifest as somatic sensations. Anxiety, motor, and depressive symptoms are interlinked but contribute individually to HRQoL. Beyond motor symptoms, cognitive and affective aspects of anxiety impact HRQoL. While anxiety and depression overlap, the somatic and cognitive aspects of anxiety play a significant role in determining HRQoL in addition to depressive symptoms. CONCLUSION Our study used the GAS and its three subscales to shed light on the connections between anxiety, depression, and motor impairment in people with PD. Although anxiety is linked to depression and motor symptoms, it independently affects the HRQoL of people with PD. Thus, it is crucial to adopt a comprehensive diagnostic approach that detects and considers the impact of anxiety on HRQoL in PD.

Abstract
BACKGROUND Several anxiety syndromes have been associated with Parkinson disease (PD), but their interactions with dopamine replacement therapy (DRT) and motor function dynamics are not completely understood. We sought to delineate how DRT impacts anxiety phenomenology in PD and whether these changes are dissociable from improved motoric function. METHODS We compared anxiety responses to DRT in two cohorts: 1) a study of 200 PD participants who completed neuropsychiatric assessments before and after taking their dopaminergic medications ("On-Off"); 2) participants in the Parkinson's Progression Markers Initiative (PPMI) de novo PD cohort who completed the State-Trait Anxiety Inventory (STAI) at the time of DRT initiation and a subsequent study visit (n = 113, mean 8-month interval). RESULTS Among On-Off participants transitioning acutely to the On-state, scores on the Hamilton anxiety rating scale decreased by 37% (t = 14.8, df = 199, p <0.0001). Among PPMI participants, STAI-state scores decreased by 10.4% following DRT initiation (t = 4.5, df = 112, p <0.0001). Item-level anxiety changes exhibited weak and nonsignificant correlations (Spearman ρ: -0.24 to 0.33) with objective MDS-UPDRS motor improvements in both immediate and sustained dopamine replacement contexts. CONCLUSION Dopamine repletion effected immediate relief of anxiety in an On-Off state comparison. A similar benefit was observed in the longitudinal PPMI cohort by comparing anxiety before and after DRT initiation, suggesting DRT confers sustained anxiolytic effects in early PD. The weak correlations between improvements to anxiety and motor function on both timescales support the view that these changes are not mediated by improved motor function.

Abstract
Although dopamine replacement therapy remains a core component of Parkinson's disease treatment, the onset of motor fluctuations and dyskinetic movements might require a range of medical and surgical approaches from a multidisciplinary team, and important new approaches in the delivery of dopamine replacement are becoming available. The more challenging, wide range of non-motor symptoms can also have a major impact on the quality of life of a patient with Parkinson's disease, and requires careful multidisciplinary management using evidence-based knowledge, as well as appropriately tailored strategies according to the individual patient's needs. Disease-modifying therapies are urgently needed to prevent the development of the most disabling refractory symptoms, including gait and balance difficulties, cognitive impairment and dementia, and speech and swallowing impairments. In the third paper in this Series, we present the latest evidence supporting the optimal treatment of Parkinson's disease, and describe an expert approach to many aspects of treatment choice where an evidence base is insufficient.

Abstract
INTRODUCTION Impulse control disorders (ICD) in Parkinson's disease (PD) and hypomanic episodes of bipolar disorder show overlapping symptoms, suggesting a shared neurobiology. To explore this, the following hypotheses are tested: (1) larger changes in affective symptoms from OFF to ON medication states will be associated with ICD, (2) antidepressant exposure will be associated with larger OFF to ON affective symptom changes, and (3) antidepressant exposure will be associated with ICD. METHODS 200 participants (mean age 65, 61 % male) were evaluated in "off" and "on" dopamine states. Affective symptoms were captured using the Hamilton Anxiety and Depression Rating Scales. Differences in clinical outcomes were compared using two-sample Wilcoxon rank-sum tests and Pearson χ2 tests. We performed multivariable logistic regression to assess the association of antidepressant exposure on ICD. RESULTS Participants with an ICD had higher anxiety and depressive scores in "on" and "off" states and larger changes in depressive symptoms from OFF to ON states compared to those without an ICD. Participants on antidepressants had higher anxiety scores in "on" and "off" states, higher depressive scores in the "off" state, and larger changes in anxiety symptoms from OFF to ON states than those not on an antidepressant. Antidepressant use was associated with a higher odds of an ICD (OR 2.3, CI [1.0-4.5], p-value 0.04). CONCLUSIONS Affective symptom severity in "on" and "off" dopamine states is associated with ICD. Antidepressant therapy may be associated with ICD. Future prospective studies clarifying temporal associations between antidepressant initiation and ICD emergence are needed.

Abstract
Neuropsychiatric mood and motivation symptoms (depression, anxiety, apathy, impulse control disorders) in Parkinson's disease (PD) are highly disabling, difficult to treat and exacerbated by current medications and deep brain stimulation therapies. High-resolution intracranial recording techniques have the potential to undercover the network dysfunction and cognitive processes that drive these symptoms, towards a principled re-tuning of circuits. We highlight intracranial recording as a valuable tool for mapping and desegregating neural networks and their contribution to mood, motivation and behavioral symptoms, via the ability to dissect multiplexed overlapping spatial and temporal neural components. This technique can be powerfully combined with behavioral paradigms and emerging computational techniques to model underlying latent behavioral states. We review the literature of intracranial recording studies investigating mood, motivation and behavioral symptomatology with reference to 1) emotional processing, 2) executive control 3) subjective valuation (reward & cost evaluation) 4) motor control and 5) learning and updating. This reveals associations between different frequency specific network activities and underlying cognitive processes of reward decision making and action control. If validated, these signals represent potential computational biomarkers of motivational and behavioural states and could lead to principled therapy development for mood, motivation and behavioral symptoms in PD.

NPJ Parkinsons Dis 2023; 9:97.

Abstract
Synucleinopathies are neurodegenerative disorders characterized by alpha-synuclein (αSyn) accumulation in neurons or glial cells, including Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA). αSyn-related pathology plays a critical role in the pathogenesis of synucleinopathies leading to the progressive loss of neuronal populations in specific brain regions and the development of motor and non-motor symptoms. Anxiety is among the most frequent non-motor symptoms in patients with PD, but it remains underrecognized and undertreated, which significantly reduces the quality of life for patients. Anxiety is defined as a neuropsychiatric complication with characteristics such as nervousness, loss of concentration, and sweating due to the anticipation of impending danger. In patients with PD, neuropathology in the amygdala, a central region in the anxiety and fear circuitry, may contribute to the high prevalence of anxiety. Studies in animal models reported αSyn pathology in the amygdala together with alteration of anxiety or fear learning response. Therefore, understanding the progression, extent, and specifics of pathology in the anxiety and fear circuitry in synucleinopathies will suggest novel approaches to the diagnosis and treatment of neuropsychiatric symptoms. Here, we provide an overview of studies that address neuropsychiatric symptoms in synucleinopathies. We offer insights into anxiety and fear circuitry in animal models and the current implications for therapeutic intervention. In summary, it is apparent that anxiety is not a bystander symptom in these disorders but reflects early pathogenic mechanisms in the cortico-limbic system which may even contribute as a driver to disease progression.
