Non-choreic movement disorders as initial manifestations of Huntington’s disease
Huntington disease HD is a rare neurodegenerative disorder of the central nervous system characterized by unwanted choreatic movements, behavioral and psychiatric disturbances and dementia. Mean age at onset of symptoms is years.
In some cases symptoms start before the age of 20 years with behavior disturbances and learning difficulties at huntinhton Juvenile Huntington disease, JHD; see this term. The classic sign is chorea that gradually spreads to all muscles.
Ve unwanted movements include tics, comparable to those seen in Tourette syndrome see this termbut these are fairly rare. Cerebellar signs can appear sporadically, similar to the presence of hypo- and hypermetria. Other less well-known, but prevalent and often debilitating features of HD include unintended weight loss, sleep- and circadian rhythm disturbances and autonomic nervous system dysfunction.
Dysarthria and dysphagia become very prominent during the creia of the disease. Talking and swallowing gradually become more problematic leading to choking at any time in some patients. All patients develop hypokinesia and rigidity leading to bradykinesia and severe akinesia.
OMIM Entry – # – HUNTINGTON DISEASE; HD
All psychomotor processes become severely impaired. Patients also experience cognitive decline. Psychiatric symptoms are very common in the early stage of the disease, often prior to onset of motor symptoms. Suicide occurs more frequently in early symptomatic patients and also in premanifest gene carriers. The most risky periods for suicide are around the time of the gene test and when independence starts to diminish.
HD is caused by an elongated CAG repeat 36 repeats or more on the short arm of chromosome 4 4p The longer the CAG repeat, the earlier the onset of disease.
In cases of JHD, the repeat ed exceeds Diagnosis is based on clinical symptoms and signs in an individual with a parent with proven HD and is confirmed by DNA determination Premanifest diagnosis should only be performed by multidisciplinary teams in healthy at-risk adult individuals who want to know whether huntingtkn carry the mutation or not. Differential diagnoses include other causes of chorea including general internal disorders or iatrogenic disorders. Phenocopies clinically diagnosed cases of Huntkngton without the genetic mutation are observed.
Prenatal diagnosis is possible by chorionic villus sampling or amniocentesis. Pre-implantation coreiaa with in vitro fertilization is offered in several countries.
To date, no cure is available. Management should be multidisciplinary and is based on treating symptoms with a view to improving quality of life. Chorea is treated with dopamine receptor blocking or depleting agents. Medication and non-medical care for depression and aggressive behavior may be required.
The progression of cogeia disease leads to complete dependency in daily life, which results in patients requiring full-time care, and finally death. The most common cause of death is pneumonia, followed by suicide. Other search option s Alphabetical list.
