Abstract
As the prevalence of Parkinson's disease (PD) grows, so too does the population at-risk of developing PD, those in the so-called prodromal period. This period can span from those experiencing subtle motor deficits yet not meeting full diagnostic criteria or those with physiologic markers of disease alone. Several disease-modifying therapies have failed to show a neuroprotective effect. A common criticism is that neurodegeneration, even in the early motor stages, has advanced too far for neuro-restoration-based interventions to be effective. Therefore, identifying this early population is essential. Once identified, these patients could then potentially benefit from sweeping lifestyle modifications to alter their disease trajectory. Herein, we review the literature on risk factors for, and prodromal symptoms of, PD with an emphasis on ones which may be modifiable in the earliest possible stages. We propose a process for identifying this population and speculate on some strategies which may modulate disease trajectory. Ultimately, this proposal warrants prospective studies.

Abstract
Drug-induced Behavioral Signature Analysis (DBSA), is a machine learning (ML) method for in silico screening of compounds, inspired by analytical methods quantifying gene enrichment in genomic analyses. When applied to behavioral data it can identify drugs that can potentially reverse in vivo behavioral symptoms in animal models of human disease and suggest new hypotheses for drug discovery and repurposing. We present a proof-of-concept study aiming to assess Drug-induced Behavioral Signature Analysis (DBSA) as a systematic approach for drug discovery for rare disorders. We applied Drug-induced Behavioral Signature Analysis to high-content behavioral data obtained with SmartCube®, an automated in vivo phenotyping platform. The therapeutic potential of several dozen approved drugs was assessed for phenotypic reversal of the behavioral profile of a Huntington's Disease (HD) murine model, the Q175 heterozygous knock-in mice. The in silico Drug-induced Behavioral Signature Analysis predictions were enriched for drugs known to be effective in the symptomatic treatment of Huntington's Disease, including bupropion, modafinil, methylphenidate, and several SSRIs, as well as the atypical antidepressant tianeptine. To validate the method, we tested acute and chronic effects of tianeptine (20 mg/kg, i. p.) in vivo, using Q175 mice and wild type controls. In both experiments, tianeptine significantly rescued the behavioral phenotype assessed with the SmartCube® platform. Our target-agnostic method thus showed promise for identification of symptomatic relief treatments for rare disorders, providing an alternative method for hypothesis generation and drug discovery for disorders with huge disease burden and unmet medical needs.

Abstract
Introduction Parkinson's disease (PD) is a multisystem neurodegenerative disorder characterized by motor and non-motor symptoms. In particular, non-motor symptoms have become increasingly relevant to disease progression. This study aimed to reveal which non-motor symptoms have the highest impact on the complex interacting system of various non-motor symptoms and to determine the progression of these interactions over time. Methods We performed exploratory network analyses of 499 patients with PD from the Cohort of Patients with Parkinson's Disease in Spain study, who had Non-Motor Symptoms Scale in Parkinson's Disease ratings obtained at baseline and a 2-year follow-up. Patients were aged between 30 and 75 years and had no dementia. The strength centrality measures were determined using the extended Bayesian information criterion and the least absolute shrinkage and selection operator. A network comparison test was conducted for the longitudinal analyses. Results Our study revealed that the depressive symptoms anhedonia and feeling sad had the strongest impact on the overall pattern of non-motor symptoms in PD. Although several non-motor symptoms increase in intensity over time, their complex interacting networks remain stable. Conclusion Our results suggest that anhedonia and feeling sad are influential non-motor symptoms in the network and, thus, are promising targets for interventions as they are closely linked to other non-motor symptoms.

Clinical uses of Bupropion in patients with Parkinson's disease and comorbid depressive or neuropsychiatric symptoms: a scoping review. BMC Neurol 2022; 22:169.

Abstract
OBJECTIVE Bupropion, an antidepressant inhibiting the reuptake of dopamine and noradrenaline, should be useful to treat depressive symptoms in patients with Parkinson's disease (PD). Limited and conflicting literature data questioned its effectiveness and safety in depressed PD patients and extended its use to other neuropsychiatric symptoms associated with this disorder. DESIGN The databases PubMed, Embase, Web of Sciences, Cochrane Library, and the grey literature were searched. Following a scoping review methodology, articles focusing on Bupropion uses in PD patients who manifested depressive or other neuropsychiatric alterations were reviewed. RESULTS Twenty-three articles were selected, including 7 original articles, 3 systematic reviews or meta-analyses, 11 case reports, 1 clinical guideline, and 1 expert opinion. Bupropion showed considerable effectiveness in reducing depressive symptoms, particularly in relation to apathy. Solitary findings showed a restorative effect on compulsive behaviour secondary to treatment with dopamine as well as on anxiety symptoms. The effect on motor symptoms remains controversial. The safety profile of this medication seems positive, but additional precautions should be used in subjects with psychotic symptoms. CONCLUSION The available literature lacks good evidence to support the use of Bupropion in PD patients presenting depressive symptoms. Further investigations are needed to extend and confirm reported findings and to produce accurate clinical guidelines.

Abstract
Depression und Parkinson-Syndrom treten häufig gemeinsam auf 1. Depressive Episoden tragen signifikant zur
Morbidität der Parkinson-Erkrankung und damit auch zur Inanspruchnahme der
Angehörigen bei. Bei Verwendung moderner Klassifikationssysteme gibt die
Mehrzahl der Autoren Prävalenzraten von bis zu 50% an 2. Diese Komorbidität wird immer noch zu
selten diagnostiziert und viel zu selten behandelt 1. Hierbei ist zu berücksichtigen, dass depressive Syndrome
nicht nur als Reaktion auf die Parkinson-Erkrankung zu interpretieren sind, da sie
häufig bereits in der präsymptomatischen Phase der
Parkinson-Erkrankung zu beobachten sind und auch bei deutlicher Besserung der
Parkinson-Symptomatik unter entsprechender Medikation häufig sistieren.

Abstract
Depression in Parkinson's Disorder (DPD) has been estimated to appear in up to 40% of people with PD and negatively impacts quality of life, motor and cognitive deficits and functional disability. Knowledge of the pathophysiology of DPD is unclear, DPD may be related to dysfunction in subcortical nuclei and the prefrontal cortex, striatal-thalamic-prefrontal and basotemporal limbic circuits, brainstem monoamine, and indolamine (i.e. dopamine, serotonin, and norepinephrine) systems. DPD is characterized by sadness, loss of interest, increased exhaustibility, feelings of helplessness, reduced drive, dysphoria, irritability, and pessimism about future. The diagnosis is complicated by overlap with PD symptoms, Detection of depression in PD should be made by psychometric depression scales. DPD is underrecognized and undertreated in clinical practice. Treatment mainly includes antidepressive medications and behavioral interventions as psychotherapy. Dopamine agonists showed some antidepressant effects, there are no sufficient numbers of RCTs. Important randomized clinical trials (RCTs) are summarized. SSRIs and SNRIs have a satisfying efficacy in DPD. TCAs are also good for improving depression. Side effects of different antidepressants (e.g. TCAs, SSRIs, SNRIs, bupropion, MAOIs) and potential interactions should be considered. In existing guidelines so far no statements, algorithms and recommendations are given for diagnosis and treatment of DPD. Methodologically adequate designed RCTs and comparative studies (NIS) which offer evidence-based results are urgently needed having the impact of DPD in mind.

Abstract
Antidepressants are one of the most important classes of psychotropic drugs and they are widely used in clinical practice, mainly in psychiatry and neurology. The main indications for the use of antidepressants are depression and anxiety disorders. First-line antidepressants are selective serotonin reuptake inhibitors, as well as serotonin-norepinephrine reuptake inhibitors which due to their dual pharmacological action have an additional effect on pain syndromes that determines their use in the treatment of neuropathic pain and fibromyalgia. A special place among the serotonin-norepinephrine reuptake inhibitors has duloxetine, which is characterized by proven efficacy in the treatment of depression, anxiety disorders, as well as isolated and comorbid pain. The optimal balance of efficacy and tolerability determines the possibility of safe use of duloxetine in patients with severe neurological disorders.

Abstract
This is the first report on the inhibitory effect of HCP on ASRs caused by the RTP. We provided Skindex-16 scores for PD with the RTP. Appropriate skincare using HCP can prevent the ASRs induced by the RTP.
Introduction The rotigotine transdermal patch (RTP) is a dopamine agonist used to treat Parkinson’s disease (PD) but is sometimes discontinued because of application site reactions (ASRs). We aimed to investigate the effect of a heparinoid-containing product (HCP) for preventing ASRs due to the RTP by conducting a randomized controlled pilot trial. Methods Twenty patients with idiopathic non-demented PD were randomized to the skin care group using a HCP (group H) and the non-skin care group (group N). The primary outcome was the change in the baseline Skindex-16 score (ΔSkindex-16) at week 4. In addition, skin symptoms were also evaluated using the Dermatology Life Quality Index (DLQI) and International Contact Dermatitis Research Group (ICDRG) system for clinical scoring allergic patch test reactions up to week 8. Results The ΔSkindex-16 score at week 4 tended to be lower in group H than in group N, although the difference was not statistically significant (−1.5 ± 2.0 vs 1.3 ± 10.9, p = 0.53). When the patients with baseline Skindex-16 scores ≥ 7 were excluded, the ΔSkindex-16 at week 4 was significantly lower in group H (−1.5 ± 2.0 vs 6.1 ± 8.6, p = 0.042). The DLQI also tended to be lower in group H at weeks 4 and 8, but not significantly (p = 0.066 and p = 0.077, respectively). The ICDRG score at week 4 was significantly lower in group H (p = 0.044). Conclusion We suggest that the HCP has a preventive effect against ASRs cause by the RTP.

Abstract
We report the case of a 67-year-old Japanese Parkinson's disease (PD) patient with depression who was successfully treated with vortioxetine. The patient's PD was being treated with levodopa (100 mg/day). As improvement was noted in PD symptoms, levodopa was continued. Subsequently, she was referred to our department due to worsening of her depressive symptoms, including depressed mood, anhedonia, decreased energy, decreased concentration, decreased motivation, insomnia, hopelessness, and worthlessness. The patient did not respond to paroxetine and escitalopram. Finally, vortioxetine improved her depressive state without worsening PD.
