Dyskinesia anxiety

Sean A Rasmussen, Patricia I Rosebush, Michael F Mazurek
BACKGROUND: Early response to antipsychotic medication within 2 weeks of initiating treatment can predict psychiatric outcomes. However, it is unclear whether early response is also predictive of extrapyramidal side effects (EPSs) associated with antipsychotic medications. METHODS: In this study, we investigated 136 consecutive antipsychotic-naive, first-episode psychosis patients naturalistically treated with haloperidol. Patients were assessed at baseline and weekly after treatment initiation using the Brief Psychiatric Rating Scale, Hamilton Depression Rating Scale, and Hamilton Anxiety Rating Scale...

The external pallidum (GPe) is a component of the indirect pathway centrally placed in the basal ganglia. Studies already demonstrated that the pharmacological disinhibition of the sensorimotor, associative, and limbic GPe produced dyskinesia, hyperactivity, and compulsive behaviors, respectively. The aim of this study was to investigate the cortical regions altered by the disinhibition of each GPe functional territory. Thus, 5 macaques were injected with bicuculline in sensorimotor, associative, and limbic sites of the GPe producing dyskinesia, hyperactivity, and compulsive behaviors, and underwent in vivo positron tomography with (18)F-2-fluoro-2-deoxy-D-glucose to identify cortical dysfunctions related to GPe disinhibition...

Up to 40% of all individuals with Parkinson's disease (PD) are estimated to experience anxiety that interferes with daily functioning. This article describes research regarding the presentation of anxiety in PD and the influence anxiety has on participation in this population. A scoping review identified 1,635 articles, of which 49 met the inclusion criteria. This review identified that anxiety in PD is often associated with a range of clinical correlates related to demographic and clinical characteristics (age, gender, disease stage, duration, progression), motor symptoms (tremor, bradykinesia, dystonia, freezing of gait, symptom severity), treatment-related complications (on/off fluctuations, on with dyskinesia, unpredictable off), and non-motor symptoms (sleep abnormalities, fatigue, cognitive impairment, depression)...

Data, regarding the use of botulinum toxin (BT-A) in laryngeal dyspnea, are scarce, coming from some cases reports in the literature, including Vocal fold paralysis, laryngeal dystonia, vocal cord dysfunction also called paradoxical motion of the vocal fold (PMVF), and post-neuroleptic laryngeal dyskinesia. There is no consensus regarding the muscles and the doses to inject. The aim of this study is to present a retrospective review of patients treated in our ENT Department by BT-A injection in this indication...

The clinical picture of catatonia includes impressive motor phenomena, such as rigidity, dyskinesia, festination, negativism, posturing, catalepsy, stereotypies and mannerisms, along with affective (e. g. aggression, anxiety, anhedonism or emotional lability) and behavioral symptoms (e.g. mutism, autism, excitement, echolalia or echopraxia). In English speaking countries seven catatonia rating scales have been introduced, which are widely used in clinical and scientific practice. In contrast, only one validated catatonia rating scale is available in Germany so far...

Background. Female Parkinson's disease (PD) patients seem to experience not only more severe motor complications and postural instability but also more pronounced depression, anxiety, pain, and sleep disturbances. Objective. The aim of the present study was to evaluate the role of sex as a possible independent predictor of HRQoL in PD. Methods. In this cross-sectional study, 621 consecutive patients treated at the University of Pécs were enrolled. Severity of PD symptoms was assessed by MDS-UPDRS, UDysRS, Non-Motor Symptoms Scale, PDSS-2, Hamilton Anxiety Scale, Montgomery-Asberg Depression Rating Scale, Lille Apathy Rating Scale, and Addenbrooke Cognitive Examination...

BACKGROUND: Since previous studies aimed to study nonmotor symptom (NMS) fluctuations in direct conjunction with motor oscillations, there are no data available on the temporal context of NMS fluctuations and motor oscillations in advanced Parkinson's disease (PD). OBJECTIVE: To evaluate circadian patterns and temporal connections of NMS and motor fluctuations in PD. METHODS: 15 controls, 17 non-fluctuating and 15 fluctuating PD patients completed two diaries by rating 4 key psychiatric (anxiety, depressive mood, inner restlessness, concentration/attention deficits), fatigue and 4 autonomic NMS (excessive sweating, sialorrhea, bladder urgency, dizziness) absent or present and motor function (Off, On with/without dyskinesia, and asleep) for every hour for 5 consecutive days...

Parkinson's disease (PD) is one of the most common neurodegenerative disorders, which affects more than six million people in the world. While current available pharmacological therapies for PD in the early stages of the disease usually improve motor symptoms, they cause side effects, such as fluctuations and dyskinesias in the later stages. In this later stage, high frequency deep brain stimulation of the subthalamic nucleus (STN-DBS) is a treatment option which is most successful to treat drug resistant advanced PD...

We report the efficacy and adverse effect profile of intraduodenal levodopa-carbidopa intestinal gel (LCIG) infusion from patients treated in a single Australian movement disorder centre. We conducted an open-label, 12 month prospective study of treatment with LCIG in patients with advanced Parkinson's disease in a single tertiary referral hospital unit specialising in movement disorders. Patients with levodopa-responsive, advanced Parkinson's disease with motor fluctuations despite optimal pharmacological treatment were enrolled and underwent a 16 hour daily infusion of LCIG for 12 months...

Negative allosteric modulators (NAMs) of metabotropic glutamate receptor subtype 5 (mGlu5) have potential applications in the treatment of fragile X syndrome, levodopa-induced dyskinesia in Parkinson disease, Alzheimer disease, addiction, and anxiety; however, clinical and preclinical studies raise concerns that complete blockade of mGlu5 and inverse agonist activity of current mGlu5 NAMs contribute to adverse effects that limit the therapeutic use of these compounds. We report the discovery and characterization of a novel mGlu5 NAM, N,N-diethyl-5-((3-fluorophenyl)ethynyl)picolinamide (VU0477573) that binds to the same allosteric site as the prototypical mGlu5 NAM MPEP but displays weak negative cooperativity...

Parkinson's disease (PD) is a common, late-onset neurodegenerative disorder that shows progressive extrapyramidal motor disorders (e.g., bradykinesia, resting tremors, muscle rigidity and postural instability) and various non-motor symptoms (e.g., cognitive impairment, mood disorders, autonomic dysfunction and sleep disorders). While dopaminergic agents such as L-3,4-dihydroxyphenylalanine (L-DOPA) and dopamine D2 agonists are widely used for the treatment of PD, there is still high clinical unmet need for novel medications that overcome the limitations of current therapies...

Buspirone, a nonbenzodiasepine anxiolytic, is a partial serotonin 5-HT1A-receptor agonist, D2-autoreceptor antagonist and low affinity 5-HT2-receptor agonist. This medication is used for treatment of generalized anxiety disorder though it may be prescribed in other anxiety states, primarily, panic disorder, sociophobia and depression. Buspirone seems to be potential in treatment of other neurological and mental disorders (tardive dyskinesia in Parkinson's disease, ataxia, behavioral disorders, cranial/brain injuries, dementia, attention-deficit hyperactivity disorder)...

This study aimed at determining the prevalence of falling in PD patients, to assess generic and disease-specific clinical and pharmacological factors, relationship with health-related quality of life (HR-QoL) and changes in falls from OFF to ON in patients with motor fluctuations. Six-hundred and eighty-three PD patients of the COPARK survey were evaluated (11 had missing data and were excluded from the analysis). Patients with falls were identified as those with a UPDRS Item 13 ≥ 1 in the ON condition. All patients were assessed in a standardized manner [demographics, treatments, Unified PD Rating Scale (UPDRS), Hospital Anxiety and Depression Scale, Pittsburg questionnaire and HR-QoL scales (SF36, PDQ39)]...

In advanced stages of Parkinson's disease, serotonergic terminals take up L-DOPA and convert it to dopamine. Abnormally released dopamine may participate in the development of L-DOPA-induced dyskinesias. Simultaneous activation of 5-HT1A and 5-HT1B receptors effectively blocks L-DOPA-induced dyskinesias in animal models of dopamine depletion, justifying a clinical study with eltoprazine, a 5-HT1A/B receptor agonist, against L-DOPA-induced dyskinesias in patients with Parkinson's disease. A double-blind, randomized, placebo-controlled and dose-finding phase I/IIa study was conducted...

Movement disorders are common in psychiatry. The movement disorder can either be the symptom of a psychiatric disorder, can share a common aetiological factor with it, or can be the consequence of psychopharmacological therapy. Most common features include tic, stereotypy, compulsion, akathisia, dyskinesias, tremor, hypokinesia and disturbances of posture and gait. We discuss characteristics and clinical importance of these features. Movement disorders are frequently present in mood disorders, anxiety disorders, schizophrenia, catatonia, Tourette-disorder and psychogenic movement disorder, leading to differential-diagnostic and therapeutical difficulties in everyday practice...

Although G protein-coupled receptors are primarily known for converting extracellular signals into intracellular responses, some receptors, such as the group 1 metabotropic glutamate receptor, mGlu5, are also localized on intracellular membranes where they can mediate both overlapping and unique signaling effects. Thus, besides "ligand bias," whereby a receptor's signaling modality can shift from G protein dependence to independence, canonical mGlu5 receptor signaling can also be influenced by "location bias" (i...
