Huntington's Disease (HD) is an autosomal dominant disease manifested in a triad of cognitive, psychiatric, and motor signs and symptoms. HD is caused by a triplet repeat (CAG)expansion in the gene Huntingtin (HTT). This disease has classically been conceptualized as a neurodegenerative disease. However, recent evidence suggests that abnormal brain development may play an important role in the etiology of HD. Huntingtin (HTT)is expressed during development and through life. In animal studies, the HTT gene has been shown to be vital for brain development. This suggests that a mutant form of HTT (gene-expanded or CAG repeats of 40 and above) would affect normal brain development. In addition, studies in adults who are gene-expanded for HD, but have not yet manifested the illness, (pre-HD subjects) have significant changes in the structure of their brain, even up to 20 years before onset of clinical diagnosis. How far back these changes are evident is unknown. One possibility is that these brain changes are present throughout life, due to changes in brain development,though initially associated with only subtle functional abnormalities.
In an effort to better understand the developmental aspects of this brain disease, the current study proposes to evaluate brain structure and function in children, adolescents, and young adults (ages 6-30) who are at risk for developing HD - those who have a parent or grandparent with HD. Brain structure will be evaluating using Magnetic Resonance Imaging (MRI) with quantitative measures of the entire brain, cerebral cortex, as well as white matter integrity via Diffusion Tensor Imaging. Brain function will be assessed by cognitive tests, behavioral assessment, and physical and neurologic evaluation. Subjects that are gene-expanded (GE) will be compared to subjects who are gene non-expanded (GNE). Changes in brain structure and/or function in the GE group compared to the GNE group would lend support to the notion that this disease has an important developmental component.

- Volume of brain structures as measured by Magnetic Resonance Imaging (MRI) [ Time Frame: 1 hour out of 6-7 hour testing day, 3-4 annual visits ]Magnetic Resonance Imaging (MRI) and Diffusion Tensor Imaging (DTI) data will be analyzed to assess brain structure based upon variables including global volume, total cerebral spinal fluid, subregion volumes, cortical surface anatomy including cortical depth, surface area and gyral shape, and symmetry between brain hemispheres, all in consideration of age, gender, and height. Results will be evaluated for comparative differences between the GE group and the GNE group. In addition, these measures of brain structure will be paired with corresponding measures of brain function to evaluate brain development based upon growth and performance.
- Quantitative assessment of cognitive skills and behavioral factors [ Time Frame: 4 hours out of 6-7 hour testing day, 3-4 annual visits ]Participants undergo a cognitive battery which will quantify skills such as attention, learning, memory. In addition, behavioral measures will be administered in both self and proxy report formats. Results will be analyzed for comparative differences between the GE group and the GNE group. In addition, these measures of brain function will be paired with appropriate measures of brain structure to evaluate brain development based upon growth and performance.
- Quantitative assessment of motor performance [ Time Frame: 1 hour out of 6-7 hour testing day, 3-4 annual visits ]Motor skill (both fine and gross) will be assessed and quantified via standard UHDRS motor exam and Q-Motor/Q-Cog equipment suite. Results will be analyzed for comparative differences between the GE group and the GNE group. In addition, these measures of brain function will be paired with appropriate measures of brain structure to evaluate brain development based upon growth and performance.
- Quantification of Neurofilament Light [ Time Frame: 10 minutes for blood draw out of 6-7 hour testing day, 3-4 annual visits ]Plasma samples will be sent for each visit to University College of London for analysis of NfL, an indicator of neuronal damage, to determine viability as a biomarker for Huntington's Disease.
Biospecimen Retention: Samples With DNA
Bio-specimens are collected and retained for all participants for genetic testing purposes and future research. Specimens are either a single sample of 3-4 teaspoons of blood drawn from the arm.
Biospecimens will be tested for the number of CAG repeats in the Huntingtin Gene. Each sample obtained will be coded with a randomly assigned number and never linked with personal identifiers. The results from the genetic analysis will be sent directly to the data manager on the project, who is the ONLY research member with access to this data. This person has no direct contact with study participants.
