psychiatric manifestation in parkinson

INTRODUCTION: Anxiety symptoms are the most common neuropsychiatric manifestation of Parkinson's disease (PD), contributing to decreased quality of life. Few longitudinal studies in PD samples have examined correlates of anxiety symptoms over time. Understanding predictor variables may help to identify novel targets for reducing anxiety in PD. The aim of this study was to identify predictors of anxiety symptoms over 3 years in a clinic-based PD cohort. METHODS: Our cohort included patients with PD at an academic medical center in the Southeastern United States (n = 105)...

INTRODUCTION: Huntington's disease (HD) is a progressive neurodegenerative disorder with motor, cognitive, and psychiatric symptoms that typically manifest in middle adulthood. Balance assessments may be useful for predicting disease onset and progression, but studies are limited. We aimed to enhance estimates of HD onset using an inexpensive and practical body sway assessment device [i.e., Wii Balance Board (WBB)]. METHODS: We assessed total body sway (TBS) on 64 HD gene carriers [Presymptomatic HD (PsHD; n = 16); Prodromal HD (ProHD; n = 16); HD (n = 32)] and 21 demographically similar normal controls (NC) employing a WBB and custom-designed laptop software...

Cognitive and movement processes involved integration of several large-scale brain networks. Central to these integrative processes are connector hubs, brain regions characterized by strong connections with multiple networks. Growing evidence suggests that many neurodegenerative and psychiatric disorders are associated with connector hub dysfunctions. Using a network metric called functional connectivity overlap ratio, we investigated connector hub alterations in Parkinson's disease. Resting-state functional MRI data from 99 patients (male/female = 44/55) and 99 age- and sex-matched healthy controls (male/female = 39/60) participating in our cross-sectional study were used in the analysis...

BACKGROUND: Huntington's disease is a progressive neurodegenerative disorder with no disease-modifying treatments. Patients experience motor, cognitive, and psychiatric disturbances, and the dorsal striatum is the main target of neurodegeneration. Mouse models of Huntington's disease show altered striatal synaptic signaling in vitro, but how these changes relate to behavioral deficits in vivo is unclear. OBJECTIVES: We aimed to investigate how striatal activity correlates with behavior in vivo during motor learning and spontaneous behavior in a Huntington's disease mouse model at two disease stages...

Anti- N -methyl-d-aspartate (NMDA) receptor encephalitis is a progressively debilitating, frequently fatal disease caused by autoantibodies against the NMDA receptor. Risk of delayed treatment is high due to variable presentations, lack of awareness and potential false negative diagnostic studies. In this case report, a woman in her 20s presented with psychiatric manifestations and rapidly declined. Dyskinetic movements and dysautonomia were observed. Initial cerebrospinal fluid and serum anti-NMDA receptor antibodies were negative...

Aceruloplasminemia is a rare autosomal recessive inherited disorder. Mutations in the ceruloplasmin gene cause depressed ferroxidase activity leading to iron accumulation. The clinical phenotype is highly variable: anemia, retinopathy, diabetes mellitus, psychiatric disorders, and neurological symptoms including parkinsonian disorders and dementia are the main features of this disease. Characterized by high serum ferritin with low transferrin saturation, aceruloplasminemia uniquely combines brain, liver and systemic iron overload...

INTRODUCTION: Biallelic intronic AAGGG repeat expansion in the replication factor C subunit 1 (RFC1) gene was recently identified in two/third of patients with cerebellar ataxia, sensory neuropathy, and bilateral vestibular areflexia syndrome (CANVAS). The phenotypic spectrum has expanded since (i.e., parkinsonism, motor neuron involvement, cognitive decline); no behavioral symptoms have been reported yet. CASE REPORT: We report an Italian family that met the diagnostic criteria for CANVAS, and RFC1-expansion was detected in five of seven...

Parkinson's disease (PD) is the second most common neurodegenerative disease and is characterized by multiple motor and non-motor symptoms. Mutations in the glucocerebrosidase ( GBA ) gene, which encodes the lysosomal enzyme glucocerebrosidase (GCase), which hydrolyzes glucosylceramide (GlcCer) to glucose and ceramide, are the most important and common genetic PD risk factors discovered to date. Homozygous GBA mutations result in the most common lysosomal storage disorder, Gaucher's disease (GD), which is classified according to the presence (neuronopathic types, type 2 and 3 GD) or absence (non-neuronopathic type, type 1 GD) of neurological symptoms...

Huntington's disease (HD) is an inherited neurodegenerative disease. People at risk for HD can choose to get predictive testing years before the clinical onset. HD is characterized by motor, cognitive and psychiatric symptoms and has a mean age at onset between 30 and 50 years, an age at which people are usually still working. This systematic review focuses on summarizing which disease-specific characteristics influence employment and working capacity in HD. Twenty-three studies were identified and showed that while employment and working capacity in HD are negatively influenced by cognitive decline and motor impairments, apathy already plays a role in the prodromal stage...

Hereditary diffuse leukoencephalopathy with spheroids is a rare genetic disorder caused by mutations of the colony-stimulating factor 1 receptor gene. It is an adult-onset leukodystrophy, with a wide spectrum of neurological and psychiatric manifestations that includes Parkinsonism, dementia, seizures, limb weakness, spasticity and abnormal motor behaviour. Alien-hand syndrome and mirror movements are rare manifestations of this and other neurodegenerative disorders. We describe a woman with progressive limb and trunk rigidity, Parkinsonism and dementia, who also had involuntary left arm levitation (part of the posterior variant of alien-hand syndrome) and left-hand mirror movements...

Patients with Parkinson's disease (PD) often present symptoms of anxiety, depression and apathy. These negative affect manifestations have been recently associated with the presence of impulsive compulsive behaviours (ICBs). However, their relation with the use of dopamine replacement therapy (DRT), a renewed risk factor for ICBs, is still not fully understood. Elucidating the role of these different ICBs predictors in PD could inform both prevention/intervention recommendations as well as theoretical models...

22q11.2 deletion syndrome is the most common microdeletion syndrome. This article reviews the different neurological manifestations of 22q11.2 deletion syndrome. The syndrome is associated with neurological disorders such as epilepsy and movement disorders. Patients with 22q11.2 DS have an increased incidence of provoked and unprovoked seizures. Provoked seizures include, amongst others, seizures due to hypocalcemia, surgery, perioperative hypoxia, antipsychotic medication, and fever. Both focal seizures, myoclonus and generalized tonic-clonic seizures occur in 22q11...

Introduction: Premutation expansions (55-200 CGG repeats) of the Fragile X Mental Retardation 1 (FMR1) gene on the X chromosome are associated with a range of clinical features. Apart from the most severe - Fragile X-Associated Tremor/Ataxia Syndrome (FXTAS) - where the most typical white matter changes affect cerebellar peduncles, more subtle changes may include impairment of executive functioning, affective disorders and/or subtle motor changes. Here we aimed to examine whether performance in selected components of executive functioning is associated with subclinical psychiatric symptoms in non-FXTAS, adult females carrying the FMR1 premutation...

Primary familial brain calcification (PFBC) is a progressive neurological disorder manifesting as bilateral brain calcifications in CT scan with symptoms as parkinsonism, dystonia, ataxia, psychiatric symptoms, etc. Recently, pathogenic variants in MYORG have been linked to autosomal recessive PFBC. This study aims to elucidate the mutational and clinical spectrum of MYORG mutations in a large cohort of Chinese PFBC patients with possible autosomal recessive or absent family history. Mutational analyses of MYORG were performed by Sanger sequencing in a cohort of 245 PFBC patients including 21 subjects from 10 families compatible with a possibly autosomal-recessive trait and 224 apparently sporadic cases...

BACKGROUND: Adrenoleukodystrophy (ALD) is an X-linked peroxisomal disorder caused by mutations in the ABCD1 gene. The clinical manifestations of ALD vary widely with some patients presenting with adrenomyeloneuropathy (AMN) that resembles the phenotype of hereditary spastic paraplegia (HSP). The aim of this study is to investigate the frequency, spectrum, and clinical features of ABCD1 mutations in Taiwanese patients with HSP phenotype. METHODS: Mutational analysis of the ABCD1 gene was performed in 230 unrelated Taiwanese patients with clinically suspected HSP by targeted resequencing...

BACKGROUND: Complex parkinsonism is the commonest phenotype in late-onset PLA2G6-associated neurodegeneration. OBJECTIVES: The aim of this study was to deeply characterize phenogenotypically PLA2G6-related parkinsonism in the largest cohort ever reported. METHODS: We report 14 new cases of PLA2G6-related parkinsonism and perform a systematic literature review. RESULTS: PLA2G6-related parkinsonism shows a fairly distinct phenotype based on 86 cases from 68 pedigrees...

Life expectancy has increased worldwide and, along with it, a greater prevalence of age-dependent disorders, chronic illnesses and comorbidities can be observed. In 2019, in both Europe and the Americas, dementias ranked 3rd among the top 10 causes of death. Parkinson's disease (PD) is the second most frequent type of neurodegenerative disease. In the last decades, globally, the number of people suffering from PD has more than doubled to over 6 million. Of all the neurological disorders, PD increased with the fastest rate...

Parkinson's disease (PD) is the second most prevalent neurodegenerative disease in North America, next to Alzheimer's disease. Patients who suffer from PD typically present with neuromuscular, cognitive, postural and psychiatric deficits, which make oral hygiene challenging, but extremely important. Although the cardinal signs of PD are movement-related, manifestations in the orofacial complex are ubiquitous. Weakened facial musculature, gaunt appearance, tremors of the tongue, lips and eyes, erratic mandibular movements, bruxism, xerostomia, sialorrhea, dysphagia, dysgeusia and glossitis are examples of the plethora of atypical orofacial findings associated with PD...

Parkinson's disease (PD) is a complex disorder characterized by a wide spectrum of symptoms. Depression and anxiety are common manifestations in PD and may be determinants of health-related quality of life (HRQoL). The objective of this study is to determine the association of depression and anxiety with the dimensions of HRQoL in subjects with PD enrolled in an association of patients. Ninety-five community-based patients with PD diagnosis at different disease stages were studied. HRQoL was assessed using the Parkinson's Disease Questionnaire (PDQ-39); depression and anxiety were assessed using the Beck Depression Inventory (BDI-II) and the State-Trait Anxiety Inventory (STAI), respectively...

Background: Infectious outbreaks, most recently coronavirus disease 2019 (COVID-19), have required pervasive public health strategies, termed lockdown measures, including quarantine, social distancing, and closure of workplaces and educational establishments. Although evidence analysing immediate effects is expanding, repercussions following lockdown measures remain poorly understood. This systematic review aims to analyse biopsychosocial consequences after lockdown measures end according to short, medium, and long-term impacts...
