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.
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.
Is HD a pathogen?
There are multiple theories on the pathogenesis of HD. It is likely that more than one process may be occurring at once , but there is evidence to support multiple individual mechanisms, including toxic neuronal aggregates, transcriptional dysregulation, excitotoxicity, mitochondrial dysfunction with altered energy metabolism, and changes in axonal transport and synaptic dysfunction (Table 2) [24–30].
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 help someone with Huntington's disease?
These strategies include: Using calendars and schedules to help keep a regular routine. Initiating tasks with reminders or assistance.
What is the diagnosis of Huntington's disease?
Diagnosis. A preliminary diagnosis of Huntington's disease is based primarily on your answers to questions, a general physical exam, a review of your family medical history, and neurological and psychiatric examinations.
Why is it so hard to maintain a healthy weight?
Difficulty maintaining a healthy body weight. Difficulty eating, higher caloric needs due to physical exertion or unknown metabolic problems may be the cause . To get adequate nutrition, you may need to eat more than three meals a day or use dietary supplements.
How do multiple interventions help?
And multiple interventions can help a person adapt to changes in his or her abilities for a certain amount of time. Medications will likely evolve over the course of the disease, depending on overall treatment goals. Also, drugs that treat some symptoms may result in side effects that worsen other symptoms.
Why do people have genetic tests?
The test can't tell you when the disease will begin or what symptoms will appear first. Some people may have the test because they find not knowing to be more stressful.
Which drugs have fewer side effects?
Other drugs, such as risperidone (Risperdal), olanzapine (Zyprexa) and quetiapine (Seroquel), may have fewer side effects but still should be used with caution, as they may also worsen symptoms.
Can Huntington's disease be confirmed by genetic testing?
If symptoms strongly suggest Huntington's disease , your doctor may recommend a genetic test for the defective gene. This test can confirm the diagnosis. It may also be valuable if there's no known family history of Huntington's disease or if no other family member's diagnosis was confirmed with a genetic test.
What is the best treatment for Huntington's disease?
Movement problems, such as chorea, for example, are a common Huntington’s symptom. Xenazine (tetraben azine) is the only medication specifically approved for Huntington’s chorea. Others, such as antipsychotics and benzodiazepines, have also demonstrated a benefit and can be used off-label.

You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.
Is Huntington disease progressive?
Huntington disease (HD) is progressive, eventually leading to disability and death (usually from a coexisting illness or infection). However, the disease affects everyone differently; the age of onset, specific symptoms, and rate of progression varies for each person with HD.
Is there a cure for Huntington's disease?
Unfortunately, there is currently no cure for Huntington disease (HD). The current goal of treatment is to slow down the course of the disease and help affected people function for as long and as comfortably as possible. [3]#N#Current treatment strategies involve the use of various medications to treat specific symptoms such as abnormal movements and behaviors. Depression and suicide are more common among affected people, so caregivers should monitor for associated symptoms and seek help if necessary. As symptoms of the disease worsen, affected people need more assistance, supervision, and care. [3]
What causes Huntington's disease?
It’s caused by a mutation of the HTT gene, which creates a toxic protein that gradually destroys vast tracts of the brain, eventually removing all the person’s mental faculties. This mutated gene is dominant, meaning that only one of your two copies of HTT needs to be faulty for you to have Huntington’s.
What is the Ionis HTT RX?
The drug in question is IONIS-HTT Rx, developed by California-based Ionis Pharmaceuticals in conjunction with researchers around the world. There are many lines of promising ongoing research, but the Ionis drug – a type of antisense oligonucleotide, or ASO – is the first that’s suggested it might be possible to suppress the disease. An ASO works by sticking to the messenger RNA that carries the information for making a specific protein from a cell’s DNA to its protein-building machinery. Then the ASO destroys the RNA, preventing the protein from being made.
How many sets of CAG are in a mutated HTT gene?
In a mutated HTT gene, a particular triplet of DNA bases, CAG, is abnormally repeated. With below 26 sets of CAG in each of your two HTT genes, you won’t get the disease, but with more than 40 in just one of them, you will – at an age that depends on the number of those extra repeats.
Is Hope high for Huntington's?
Hope is now high among those affected by Huntington’s too. But until a treatment becomes generally available, their options remain limited. There are medications to help manage some of the symptoms – such as depression, mood swings and involuntary movements – but nothing can yet slow its progression.
Does huntingtin lower cerebrospinal fluid?
With an ASO selected, the UCL trial then confirmed the drug’s safety and its ability, when injected into the spinal cord, to lower huntingtin levels in the cerebrospinal fluid . The excitement of the result lay in its biological effect: its success in lowering the protein in humans was, Tabrizi says, “beyond what I’d ever hoped”.
Why did participants not want to know their risk?
The two primary reasons why participants did not want to know their risk were because they felt no effective cure or treatment exists and their inability to undo the knowledge they learned from the test.
Can you get counseling if you don't want to be tested?
The study, published in Clinical Genetics, also suggests that individuals who have chosen not to be tested can benefit from supportive counseling, which is not usually offered.
