Apathy and Functional Status in Early-Stage Huntington's Disease.

Objective: Apathy is common in Huntington's disease (HD) and difficult to treat. Multiple recent calls have been made to increase understanding of apathy across the spectrum of HD severity. Functional status is an important outcome in HD trials; however, no consensus currently exists regarding the impact of apathy on functional status in HD.

Deciphering Cognitive Impairments in Huntington's Disease: A Comparative Study of Stroop Test Variations.

Background: Huntington's disease (HD) is a neurodegenerative disorder marked by cognitive impairment, movement abnormalities, and behavioral disturbances. The Stroop Color Word Test (SCWT) is a widely used tool to detect cognitive decline in HD. Variations in SCWT formats-horizontal (original) and vertical (Golden)-may influence performance, given HD's impact on cognitive and oculomotor abilities.

Influence of anosognosia on patient-reported outcomes for psychiatric symptoms and quality of life in Huntington's disease.

Introduction: Anosognosia, defined as reduced awareness of one's deficit or symptom, is common in Huntington's disease (HD) and detectable at each disease stage. The impact of anosognosia on self-reporting in HD populations is critical to understand given growing use of patient-reported outcomes in HD clinical care and research. We aimed to determine the influence of anosognosia on patient-reported outcome measures assessing psychiatric symptoms and quality of life in HD.
