Neurobiological Predictors of Huntington's Disease (PREDICT-HD)

2014-08-27 03:55:35 | BioPortfolio

Summary

The purpose of this trial is to study early brain and behavioral changes in people who have the gene expansion for Huntington's disease, but are currently healthy and have no symptoms.

Description

Huntington's Disease (HD) is an inherited disease that causes changes in a person's ability to control movements, thinking, and feelings. The intent of this study is to learn more about the beginning changes in thinking skills, emotional regulation, and brain structure and function as a person begins the transition from health to HD.

Preliminary studies indicate that people with HD may have marked decline before an actual diagnosis. This study will help reveal the earliest indicators of the disease and what factors influence the age at which a person carrying the gene develops the disease. It is necessary to get information on the early stages of HD in order to develop drugs that can slow or postpone the onset of HD. The investigators hope this study will provide essential information for future trials of experimental drugs for HD.

During this 4-year study, participants will undergo several detailed tests, including MRI scans of the brain, cognitive assessments, physical exams, and neurological and psychiatric testing.

Medical and Biotech [MESH] Definitions

A biochemical phenomenon in which misfolded proteins aggregate either intra- or extracellularly. Triggered by factors such as MUTATION, POST-TRANSLATIONAL MODIFICATIONS, and environmental stress, it is generally associated with ALZHEIMER DISEASE; PARKINSON DISEASE; HUNTINGTON DISEASE; and TYPE 2 DIABETES MELLITUS.

Membrane glycosylphosphatidylinositol-anchored glycoproteins that may aggregate into rod-like structures. The prion protein (PRNP) gene is characterized by five TANDEM REPEAT SEQUENCES that encode a highly unstable protein region of five octapeptide repeats. Mutations in the repeat region and elsewhere in this gene are associated with CREUTZFELDT-JAKOB DISEASE; FATAL FAMILIAL INSOMNIA; GERSTMANN-STRAUSSLER DISEASE; Huntington disease-like 1, and KURU.

A phenyl-piperidinyl-butyrophenone that is used primarily to treat SCHIZOPHRENIA and other PSYCHOSES. It is also used in schizoaffective disorder, DELUSIONAL DISORDERS, ballism, and TOURETTE SYNDROME (a drug of choice) and occasionally as adjunctive therapy in MENTAL RETARDATION and the chorea of HUNTINGTON DISEASE. It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279)

A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea. (From Adams et al., Principles of Neurology, 6th ed, pp1060-4)

A protein that is highly expressed in the nervous system as well as other tissues; its size and structure vary due to polymorphisms. Expanded CAG TRINUCLEOTIDE REPEATS have been identified in the Huntingtin (HD) Gene of patients with HUNTINGTON DISEASE and are associated with abnormal PROTEIN AGGREGATES. Huntingtin interacts with proteins involved in a variety of gene expression and cellular processes; it is also essential for embryonic development.
