Atypical social cognitive processing in premotor Huntington's disease: a single case study

Area of Science:

• Neuroscience
• Neurology
• Clinical Case Study

Background:

• Presents a case of a 52-year-old male with pre-motor Huntington's disease (HD).
• Highlights significant negative symptomatology and behavioral changes impacting social and occupational life.
• Notes the absence of overt motor symptoms at this stage.

Purpose of the Study:

• To detail the clinical and neuropsychological presentation of pre-motor Huntington's disease.
• To emphasize the impact of non-motor symptoms on patient's functional ability.
• To illustrate early social cognitive deficits in HD.

Main Methods:

• Detailed clinical examination.
• Repeat neuropsychological testing focusing on executive function and social cognition.
• Longitudinal assessment over two years (ages 50 and 52).

Main Results:

• Identified behavioral, psychiatric, and social-affective deficits.
• Demonstrated significant impact on social, occupational, and interpersonal functioning.
• Documented changes in executive function and social cognition.

Conclusions:

• Social cognitive changes can precede motor symptoms in Huntington's disease by months or years.
• Unrecognized deficits can severely impact an individual's lifestyle and functional capacity.
• This case underscores the importance of recognizing non-motor symptoms for early HD diagnosis and management.
