Affective disorders and personality changes have long been considered pre-motor aspects of Parkinson's disease (PD). Many authors have used the term "premorbid personality" to define distinctive features of PD patients' personality characterized by reduced exploration of new environmental stimuli or potential reward sources ("novelty seeking") and avoidance behaviour ("harm avoidance") present before motor features. The functional correlates underlying the personality changes described in PD, implicate dysfunction of meso-cortico-limbic and striatal circuits...

Neuropsychiatric symptoms are common in Parkinson's disease (PD) and have a disproportionate impact on quality of life and carer burden. Pharmacological treatment is the main approach in dealing with these symptoms, but it is limited by variable efficacy and risk of drug interactions. Non-pharmacological approaches using the cognitive-behavioural therapy (CBT) model are viable alternatives and in this review paper we summarise the evidence of CBT for three of the most common psychiatric manifestations of PD: depression and anxiety, impulse-control disorders and insomnia...

BACKGROUND: Executive functions including behavioral adaptation and impulse control are commonly impaired in movement disorders caused by striatal pathology. However, as yet it is unclear what aspects of behavioral abnormalities are related to pathology in which striatal subcomponent, that is, the matrix and the striosomes. We therefore studied cognitive control in X-linked dystonia-parkinsonism, a model disease of striosomal degeneration, using behavioral paradigms and EEG. METHODS: We studied genetically confirmed X-linked dystonia-parkinsonism patients (N = 21) in their early disease stages and healthy matched controls...

Why do we make hasty decisions for short-term gain? Rapid decision-making with limited accumulation of evidence and delay discounting are forms of decisional impulsivity. The subthalamic nucleus is implicated in inhibitory function but its role in decisional impulsivity is less well-understood. Here we assess decisional impulsivity in subjects with obsessive compulsive disorder who have undergone deep brain stimulation of the limbic and associative subthalamic nucleus. We show that stimulation of the subthalamic nucleus is causally implicated in increasing decisional impulsivity with less accumulation of evidence during probabilistic uncertainty and in enhancing delay discounting...

Lysosomal transport of cargos in neurons is essential for neuronal proteostasis, transmission and functional motors and behaviors. Lysosomal malfunction including storage disorders is involved in the pathogenesis of Parkinson's disease (PD). Given the unclear molecular mechanisms of diverse defects in PD phenotypes, especially behavioral deficits, this mini review explores the cellular contexts of PD impulse control disorders and the molecular aspects of lysosomal cross-membrane transports. Focuses are paid to trace metal involvements in α-synuclein assembly in Lewy bodies, the functions and molecular interactions of ATP13A2 as ATPase transporters in lysosomal membranes for cross-membrane trafficking and lysosomal homeostasis, and our current understandings of the neural circuits in ICD...

Background: Subthalamic Nucleus Deep Brain Stimulation (STN-DBS) is highly effective in alleviating motor symptoms of Parkinson's disease (PD) which are not optimally controlled by dopamine replacement therapy. Clinical studies and reports suggest that STN-DBS may result in increased impulsivity and de novo impulse control disorders (ICD). Objective/Hypothesis: We aimed to compare performance on a decision making task, the Iowa Gambling Task (IGT), in healthy conditions (HC), untreated and medically-treated PD conditions with and without STN stimulation...

Non-motor features have a great impact on progression and quality of life in individuals with Parkinson's disease. Current treatments for PD are limited and apomorphine is one of the advanced therapies available with advantageous effects on motor complications. Several studies have suggested that apomorphine has potential benefits in PD patients beyond its established role in the treatment of motor fluctuations and levodopa-induced dyskinesia. This review examines the efficacy of apomorphine in the treatment of non-motor symptoms (NMS), describing recent studies that highlight its possible effect on cognition...

Apomorphine infusion or injection is an important dopamine agonist non-oral therapy usually used in advanced Parkinson's disease (PD) with refractory motor fluctuations. The drug also has appreciable efficacy for nonmotor fluctuations and is the quickest to reverse predictable "off" periods. Current subcutaneous administration, however, is complicated by problems associated with needle-based therapies, such as skin nodule formation, skin irritation, and avoidance of this treatment option by needle-phobic subjects...

Pramipexole (PPX) is a high-affinity D2-like dopamine receptor agonist, used in the treatment of Parkinson's disease (PD) and restless leg syndrome. Recent evidence indicates that PPX increases the risk of problem gambling and impulse-control disorders in vulnerable patients. Although the molecular bases of these complications remain unclear, several authors have theorized that PPX may increase risk propensity by activating presynaptic dopamine receptors in the mesolimbic system, resulting in the reduction of dopamine release in the nucleus accumbens (NAcc)...

To document specific learning mechanisms in patients with Parkinson's disease (PD) with and without impulse control disorder (ICD). Thirty-two PD patients receiving dopamine replacement therapy (DRT) were investigated. Sixteen were diagnosed with ICD (ICD (+) ) and 16 PD patients matched for levodopa equivalence dosage, and DRT duration and severity of disease did not show impulsive behavior (non-ICD). Short-term learning of inhibitory control was assessed by an experimental procedure which was intended to mimic everyday life...

Parkinson's disease (PD) is characterized by motor symptoms, such as resting tremor, bradykinesia and rigidity, but also features non-motor complications. PD patients taking dopaminergic therapy, such as levodopa but especially dopamine agonists (DAs), evidence an increase in impulse control disorders (ICDs), suggesting a link between dopaminergic therapy and impulsive pursuit of pleasurable activities. However, impulsivity is a multifaceted construct. Motor impulsivity refers to the inability to overcome automatic responses or cancel pre-potent responses...

BACKGROUND: Impulse-control behaviors (ICBs) are increasingly recognized in Parkinson's disease (PD) as drug-related effects of dopaminergic mediation that occur in 15% to 35% of patients with PD. The authors describe the design and evaluation of a new, clinician-rated severity scale for the assessment of syndromal and subsyndromal forms of impulse-control disorders (ICDs), simple (punding) and complex (hobbyism) repetitive behaviors, and compulsive overuse of medication (dopamine dysregulation syndrome)...

To determine the clinical and demographic correlates of persistent, remitting, and new-onset impulse control behaviors (ICBs) before and after subthalamic deep brain stimulation (STN-DBS) in Parkinson's disease (PD). We compared the pre- and post-surgical prevalence of ICBs, classified as impulse control disorders (ICD), dopamine dysregulation syndrome (DDS), and punding in 150 consecutive PD STN-DBS-treated patients and determined the association with motor, cognitive, neuropsychological, and neuropsychiatric endpoints...

Although Parkinson disease (PD) is defined clinically by its motor symptoms, it is increasingly recognized that much of the disability and worsened quality of life experienced by patients with PD is attributable to psychiatric symptoms. The authors describe a model of multidisciplinary care that enables these symptoms to be effectively managed. They describe neuropsychiatric complications of PD itself and pharmacologic and neurostimulation treatments for parkinsonian motor symptoms and discuss the management of these complications...

RATIONALE: Whilst dopamine agonist therapies can successfully manage the symptoms of diseases such as Parkinson's disease (PD), fibromyalgia and restless leg syndrome, they can also cause impulse control and addiction disorders such as gambling disorder (GD). These compulsive behaviours seriously undermine the utility of such treatments. OBJECTIVES: The objective of the study was to model this phenomenon using a rodent slot machine task (rSMT) in order to investigate the neurobiological basis underlying such behavioural changes...

Valproic acid (VPA) is approved by the Food and Drug Administration (FDA) for the treatment of manic or mixed episodes associated with bipolar disorder. VPA is also used off-label to treat other conditions in psychiatry such as impulse control disorders, major depression, and posttraumatic stress disorder (PTSD). Although VPA is mostly well-tolerated, common adverse effects include gastrointestinal symptoms (nausea, vomiting, diarrhea), neurological symptoms (sedation, ataxia, tremor), weight gain, and alopecia...

During the last 25 years, more than 100,000 patients have been treated with Deep Brain Stimulation (DBS). While human clinical and animal preclinical research has shed light on the complex brain-signaling disturbances that underpin e.g., Parkinson's disease (PD), less information is available when it comes to complex psychosocial changes following DBS interventions. In this contribution, we propose to more thoroughly investigate complex personality-related changes following deep brain stimulation through refined and reliable instruments in order to help patients and their relatives in the post-surgery phase...

BACKGROUND: Our daily activities imply displacements on various types of soil. For persons with gait disorder or losing functional autonomy, walking on some types of soil could be challenging because of the risk of falling it represents. METHODS: In this paper, we present, in a first part, the use of an enactive shoe for an automatic differentiation of several types of soil. In a second part, using a second improved prototype (an enactive insole), twelve participants with Parkinson's disease (PD) and nine age-matched controls have performed the Timed Up and Go (TUG) test on six types of soil with and without cueing...
