Presentation
This condition accounts for about 0.7% of all HD-like presentations. [jnnp.bmj.com]
We therefore propose that a diagnosis of HDL2 should be considered in a wide spectrum of neuropsychiatric and abnormal movement presentations. [scielo.org.za]
The present study indicates that lutein is a promising candidate for the management of HD and related conditions. [liebertpub.com]

- Short Arm
Etiology and Pathophysiology Associated with a CAG trinucleotide repeat expansion of the huntingtin gene (HTT) on the short arm of chromosome 4 (4p16.3) causing a toxic gain-of-function mutation The gene encodes the protein huntingtin, which plays a role [unboundmedicine.com]
Each chromosome has a short arm designated as “p” and a long arm identified by the letter “q.” Chromosomes are further subdivided into bands that are numbered. [rarediseases.org]
Pathophysiology In HD there is an excessive sequence of CAG repeats in part of the HTT ("Huntingtin") gene, which is located on the short arm of chromosome 4 [3]. [physio-pedia.com]
The gene responsible for HD is HTT, which is located on the short arm of chromosome 4 (4p16.3). This gene produces a protein known as huntingtin, whose function remains unclear. [bcm.edu]

Neurologic
- Involuntary Movements
Chorea (involuntary movements) is a much less prominent feature and may be absent altogether. [huntingtonsociety.ca]
In the middle stage, the movement disorder may become more of a problem. Medication for chorea may be considered to provide relief from involuntary movements. [hdsa.org]
Defective huntingtin protein leads to brain changes that cause abnormal involuntary movements, a severe decline in thinking and reasoning skills, and irritability, depression and other mood changes. [alz.org]

Movement disorders The movement disorders associated with Huntington's disease can include both involuntary movement problems and impairments in voluntary movements, such as: Involuntary jerking or writhing movements (chorea) Muscle problems, such as [mayoclinic.org]
- Irritability
Irritability: For severe anger and threatening behavior, experts agree that an atypical antipsychotic drug is the preferred approach. [alz.org]
The three areas that health care providers often try to treat with medications are the involuntary movements, irritability and obsessive-compulsive tendencies. [consumer.healthday.com]

Mood disturbance is usually the first symptom seen, with bipolar disorder -like mood swings that may include mania, depression, extreme irritability or angry outbursts, and psychosis. [medicinenet.com]

Workup
DNA testing is used to diagnose HD; workup of the disease in asymptomatic individuals should also involve neurological and psychological examination in addition to genetic counseling. [arupconsult.com]

Treatment and outcomes There is currently no cure for Huntington's disease and no way to slow or stop the brain changes it causes. Treatments focus on managing symptoms. [alz.org]
We work with UAB functional neurosurgeons to coordinate treatment strategies for movement disorders, including PD, dystonia, and essential tremor. [uabmedicine.org]
Possible future treatments Various new treatments for HD are being studied. They include gene therapy treatments and various treatments with medicines. For example, trials looking at the effect of a new medicine called pridopidine are underway. [patient.info]
Prognosis

Diagnosis/ prognosis: There is no treatment or cure for Huntington’s Disease, and the patient eventually becomes completely dependent on others for daily functioning. [who.int]
Treatment and prognosis No treatment is currently generally available 4. [radiopaedia.org]
Prognosis Prognosis has historically been somewhat bleak for people with HD. Complications related to movement abnormalities and immobility, such as pneumonia and respiratory complications, are a common cause of death in HD. [encyclopedia.com]
What is the outlook (prognosis) with Huntington's disease (HD)? HD is a condition that slowly progresses so that you gradually develop more, and worsening, symptoms. [patient.info]
Etiology
