Keane Lim, Yuen Mei See, Jimmy Lee
The discovery of endocannabinoid's role within the central nervous system and its potential therapeutic benefits have brought forth rising interest in the use of cannabis for medical purposes. The present review aimed to synthesize and evaluate the available evidences on the efficacy of cannabis and its derivatives for psychiatric, neurodegenerative and movement disorders. A systematic search of randomized controlled trials of cannabis and its derivatives were conducted via databases (PubMed, Embase and the Cochrane Central Register of Controlled Trials)...

Huntington's disease (HD) is an incurable, neurodegenerative disease, which manifests via a triad of progressive symptoms: motor impairment, psychiatric disorders, and cognitive decline. Conventionally, the HD diagnosis is based on the presence of involuntary choreiform movements and a positive genetic test for the CAG-expanded allele gene. Although the diagnosis focuses on the motor part of the triad, there is increasing evidence that both cognitive and neuropsychiatric symptoms can, and often do, present decades before the onset of motor symptoms...

AIM: The symptoms of Huntington's disease are well known, yet the symptoms of juvenile Huntington's disease (JHD) are less established due to its rarity. The study examined a cluster of symptoms considered to be common, but under-recognized in JHD: pain, itching, sleeping difficulties, psychosis and tics. MATERIALS & METHODS: A symptom survey was constructed using the online tool Qualtrics and dispersed to JHD caregivers through websites. RESULTS: A total of 33 surveys were completed...

Almost all patients with Huntington disease (HD) show some form of behavioral changes during the disease progression. These behavioral manifestations may already be present before cognitive or motor symptoms become apparent, and vary from subtle anxiety to severe psychosis and suicide attempts. These behavioral manifestations are related to both psychologic factors, like the burden of having a severe disease, and biologic factors that are related to the disease itself. In this chapter, both nonpharmacologic and pharmacologic interventions are discussed...

Huntington's disease (HD) is a fatal neurodegenerative disorder characterized by motor dysfunction, cognitive deficits and psychosis. HD is caused by mutations in the Huntingtin (HTT) gene, resulting in the expansion of polyglutamine (polyQ) repeats in the HTT protein. Mutant HTT is prone to aggregation, and the accumulation of polyQ-expanded fibrils as well as intermediate oligomers formed during the aggregation process contribute to neurodegeneration. Distinct protein homeostasis (proteostasis) nodes such as chaperone-mediated folding and proteolytic systems regulate the aggregation and degradation of HTT...

Huntington's disease (HD) is rare variant of progressive neurodegenerative disorder which follows an autosomal dominant pattern. Psychiatric comorbidities are not uncommon with HD. Mood disorder, cognitive disturbances, anxiety disorders, and psychosis are the psychiatric comorbidities reported with HD. We report here a case of HD, where psychosis developed during illness. Prognosis of psychosis in HD is emphasized in this report with review of literature.

BACKGROUND: Tetrabenazine (TBZ) is the only US Food and Drug Administration-approved drug for the treatment of chorea related to Huntington's disease and other hyperkinetic disorders. TBZ was first synthesized in 1950, and was then used for the treatment of psychosis. But later its potential in treating hyperkinetic disorders was proved by its ability to block vesicular monoamine transporters 2 and deplete monoamine stores. There is still lack of awareness about the therapeutic potential of this drug...

The endocannabinoid system (ECS) comprises a complex of receptors, enzymes, and endogenous agonists that are widely distributed in the central nervous system of mammals and participates in a considerable number of neuromodulatory functions, including neurotransmission, immunological control, and cell signaling. In turn, the kynurenine pathway (KP) is the most relevant metabolic route for tryptophan degradation to form the metabolic precursor NAD(+). Recent studies demonstrate that the control exerted by the pharmacological manipulation of the ECS on the glutamatergic system in the brain may offer key information not only on the development of psychiatric disorders like psychosis and schizophrenia-like symptoms, but it also may constitute a solid basis for the development of therapeutic strategies to combat excitotoxic events occurring in neurological disorders like Huntington's disease (HD)...

Huntington's disease (HD) is an autosomal dominant neurodegenerative disease characterized by a triad of progressive motor dysfunction, cognitive decline and psychiatric disturbances. The hallmark of HD is the distinctive choreiform movement disorder that typically has a subtle, insidious onset in the fourth to fifth decade of life and gradually worsens over 10 to 20 years until death. Notably, two-thirds of HD patients present with chorea and one third with mental changes. The prevalence of psychiatric symptoms is significantly higher than in the general population, and is estimated to be around 66-73%...

Behavioral symptoms are an important feature of Huntington's disease and contribute to impairment in quality of life. The Movement Disorder Society commissioned the assessment of the clinimetric properties of rating scales in Huntington's disease to make recommendations regarding their use, following previously used standardized criteria. A systematic literature search was conducted to identify the scales used to assess behavioral symptoms in Huntington's disease. For the purpose of this review, 7 behavioral domains were deemed significant in Huntington's disease: irritability, anxiety, depression, apathy, obsessive-compulsive behaviors, psychosis, and suicidal ideation...

Huntington's disease is characterised by a triad of motor symptoms (choreic movements), psychiatric symptoms and cognitive decline. Much less is known about the psychiatric symptoms such as psychosis and anxiety than about the motor symptoms. We discuss the case of a patient with Huntington's disease and psychosis and comment on the possible types of medication that should be used.

This is a case of a 60-year-old man who presented with a 6-month history of increasing agitation and emotional volatility. His family brought him to the emergency room as they were concerned about his threatening and aggressive behaviour. The patient was initially incoherent and uncooperative. During the interview, the patient's family revealed that he had a previous diagnosis of Huntington's disease; there was also a family history of personality changes preceding Huntington's chorea. The patient was admitted to the psychiatric inpatient unit and started on low-dose risperidone...

INTRODUCTION: Psychosis is a major psychiatric problem that often occurs at the interface of psychiatry and the neurological specialty of movement disorders. Psychotic syndromes are common in treated movement disorder patients, and almost all antipsychotic drugs produce movement disorders. There is little published data on psychosis in movement disorders aside from Parkinson's disease (PD). AREAS COVERED: In this review, we focus primarily on PD, in which about 30% of treated patients have visual hallucinations and 5-10% have paranoid delusions; dementia with Lewy bodies, a variant of PD in which dementia occurs early and psychotic symptoms are common; Huntington's disease (HD), an inherited disorder that causes behavioral problems, frequently including psychosis; and tardive dyskinesia (TD), a group of movement disorder syndromes caused by antipsychotic drugs...

Huntington disease (HD) is an inherited, progressive, autosomal dominant disorder. Some patients develop severe chorea or cognitive symptoms. The genetic defect causes progressive atrophy of the striatum, the cortex and extrastriatal structures (Sheperd GM. Corticostriatal connectivity and its role in disease. Nat Rev Neurosci 2013;14:278-91). The precise timing of clinical diagnosis of HD is poorly characterized and is mainly based on motor symptoms (Huntington, Study and Group.

The GGGGCC (G4C2) repeat expansion in C9ORF72 is the most common cause of familial amyotrophic lateral sclerosis (ALS), frontotemporal lobar dementia (FTLD) and ALS-FTLD, as well as contributing to sporadic forms of these diseases. Screening of large cohorts of ALS and FTLD cohorts has identified that C9ORF72-ALS is represented throughout the clinical spectrum of ALS phenotypes, though in comparison with other genetic subtypes, C9ORF72 carriers have a higher incidence of bulbar onset disease. In contrast, C9ORF72-FTLD is predominantly associated with behavioural variant FTD, which often presents with psychosis, most commonly in the form of hallucinations and delusions...

Huntington's disease (HD) is a dominantly inherited progressive neurological disease characterized by chorea, an involuntary brief movement that tends to flow between body regions. HD is typically diagnosed based on clinical findings in the setting of a family history and may be confirmed with genetic testing. Predictive testing is available to family members at risk, but only experienced clinicians should perform the counseling and testing. Multiple areas of the brain degenerate, mainly involving the neurotransmitters dopamine, glutamate, and γ-aminobutyric acid...
