What is Huntington's disease?
Huntington’s disease (HD) is a hereditary, progressive neurodegenerative disease clinically characterized by abnormal involuntary movements, behavioral disturbance, cognitive dysfunction, and psychiatric disease. The disease is caused by a CAG (glutamine) trinucleotide expansion in exon 1 of the huntingtin (htt) gene at the location 4p16.9 [1]. The normal function of httis not known, but it may be involved in internal cell signaling, maintenance of cyclic adenosine monophosphate response element binding protein, and preventing neuronal toxicity [2]. Early evidence suggests that the binding of the Ras homologue enriched in striatum protein to mutant htt(mhtt) may be necessary to cause cellular toxicity [3]. However, why the protein causes cellular toxicity in adulthood is not well understood. There is evidence suggesting that the interaction of the group 1 metabotropic glutamate receptors and mhttprotein may be at the root of delayed onset [4].
What is the best treatment for dystonia?
For patients with the akinetic form of HD (Westphal variant), antiparkinsonian medications, such as levodopa, dopamine agonists, and amantadine, may be beneficial [103–106]. Botulinum toxin injections can also be considered for focal dystonia associated with HD, both typical presentation and Westphal variant. Even in patients with chorea, underlying dystonia and/or bradykinesia may be present and needs to be addressed.
What is the best medication for chorea?
Other medications that are commonly considered when treating chorea include dopamine anta gonists, benzodiazepines, and glutamate antagonists. Dopamine antagonists (neuroleptics) are perhaps the most commonly considered agents in the management of chorea and psychosis in patients with HD, but few double-blind, placebo-controlled studies evaluating the efficacy and safety of these agents have been published [75–77]. None of the typical neuroleptics have been found to be effective in reducing chorea in placebo-controlled trials. However, in a study of haloperidol in 10 patients, oral doses of 1.5–10.0 mg/day corresponded with at least a 30 % reduction in chorea compared with baseline [78]. The quantity and quality of these efficacy data need to be taken into account when considering the risks of using typical neuroleptics, particularly tardive dyskinesia. Apathy and akathisia, other potential adverse effects of the dopamine receptor blockers, can be particularly problematic in patients with HD, as they may not have the insight to recognize these problems or may wrongly attribute the symptoms to HD.
Does chorea require a long term treatment?
Overall, there is not enough evidence available to guide long-term symptomatic treatment in HD, and double-blind and long-term studies assessing various treatment strategies in HD are needed [55]. Despite the lack of evidence, an American Academy of Neurology Guidelines publication was recently released recommending consideration of tetrabenazine (TBZ), amantadine, or riluzole if chorea requires treatment [46]. A Cochrane review of studies for the symptomatic treatment of HD examined 22 trials that involved 1254 different participants [56]. Nine trials had a crossover design and 13 were conducted in parallel. The studies examined were of relatively short duration, ranging from 2 to 80 weeks. The number of trials examining various pharmacological interventions included antidopaminergic drugs (n = 5), glutamate receptor antagonists (n = 5), and energy metabolites (n = 5). Based on available evidence, the authors of the Cochrane review concluded that only TBZ showed clear efficacy for the control of chorea, but “no statement can be made regarding the best medical practice for the control of motor and non-motor symptoms in HD”.
How to treat behavioral dyscontrol?
Behavioral dyscontrol can be a severely disabling symptom of HD causing distress to the patient, family, and caregivers. Environmental approaches and cognitive interventions are the mainstay of treatments, but pharmacological agents can augment addressing disruptive behaviors. Depression, anxiety, aggressive, impulsive, and obsessive–compulsive behaviors are also frequently treated pharmacologically and require behavioral intervention, but caution should be used to avoid oversedation and apathy, already common in patients with HD. Although not well-studied, cognitive approaches to treat behavior may be more effective than pharmacotherapy for some aspects of the disease [40]. There have been few clinical trials to examine the effect of agents for cognition in HD such as donepezil, rivastigmine, and atomoxetine. None of the trials to date have demonstrated significant improvement [41–43]. Recent advances in the cognitive aspect of HD have focused on finding improved methods of diagnosing and tracking changes over time [44].
How is HD diagnosed?
HD is diagnosed based on the presence of typical motor findings commonly in the setting of a family history of the disease. There may be other manifestations of HD at the time of presentation or prior to diagnosis based on personality changes or behavioral and cognitive symptoms. A DNA test showing abnormal CAG expansion in the httgene can be used to confirm the diagnosis in symptomatic individuals. With proper genetic counseling and at the patient’s request, DNA analysis can be performed in individuals at risk for developing HD under the care of experienced clinicians.
Is there a treatment for chorea?
Although there is no established treatment to delay the onset or forestall the progression of HD, symptomatic treatment of chorea based on the neurochemical pathology known may be beneficial in some individuals, as it may have a favorable effect on motor function, quality of life, and safety [5–7]. Clinicians may also consider treatment for dystonia, other movement disorders, and non-motor aspects of HD.

What are the effects of HD?
HD is a result of changes in the brain, so it's understandable that cognitive abilities are affected. While memory can be affected, other areas of cognition are impacted as well. These include impaired executive functioning (such as the ability to plan and make decisions), poor concentration, a lack of focus, poor judgment and a lack of insight into your own behaviors. A lack of inhibitions may also develop. For example, if you have HD, you might do something that you normally wouldn't feel is appropriate because your impulse control is decreased.
Can you manage HD?
HD has a wide range of symptoms that may develop , some of which can be successfully managed with medications and non-drug approaches. Before delving into treatments, understanding symptoms as part of the disease can also help cope with them and take a more active role in your own or a family member's care.
Do people with Huntington's disease need help?
Most importantly, people with HD and their families have a risk for isolation. Know that there are resources and support available to encourage you and help you determine your next steps. If you're not sure what to do or need help, the Huntington's Disease Society of America has local chapters as well as online support groups that can encourage you, answer your questions or walk with you or just be a listening ear as you live with HD.
Is there a cure for HD?
While there is no cure available for HD at this time , there are a few medications and complementary approaches that may help relieve some symptoms for a time. Keep in mind that you should not use complementary or supplementary substances without checking with your physician, as some can have significant negative side effects or drug interactions with your other medications.

What is the EHDN guidelines?
The EHDN guidelines task force developed guidelines between 2015 and 2018 based on a formalized consensus method , adapted from the 2015 French Health Authority recommendations (HAS) ( https://www.has-sante.fr/portail/jcms/c_272505/recommandations-par-consensus-formalize-rcf ). This method combines exhaustive review of the literature, experts' proposals, and external scoring of the proposals until agreement ( Figure 1 ). This is particularly suitable when at least two of the following conditions are met (1) absence or insufficiency of high-level evidence specifically addressing the questions asked; (2) possibility of declining the theme in easily identifiable clinical situations; (3) controversy, with the need to identify by an independent group situation in which a practice is deemed appropriate. Its main advantages are (1) its ability to identify the degree of agreement or indecision among experts (2) the strict independence between the steering group, which formulates the proposals to be put to the vote, and the rating group which judges the appropriateness.

What are the symptoms of Huntington's disease?
The onset of Huntington’s disease (HD) is heralded by a wide range of symptoms, from behavioral ones, such as depression and irritability, to physically visible ones, such as bodily tremors, bradykinesia, akinesia, and dysphagia. As the disease advances, symptoms become progressively severe.
How to manage HD?
Managing HDThough people with the HD allele will eventually show symptoms, there are many lifestyle choices that can make the disease easier to manage. People with HD can engage in many activities – such as physical therapy and exercise – that help them deal with symptoms. Also, scientists have recognized that genes only tell part of the story, as described here. There is great variability in age of onset and progression of disease, only about 40% of which can be explained by the number of CAG repeats – and lifestyle choices might account for some of that variability. So while no one can choose their own genes, people at risk for HD can choose a healthy lifestyle.
