Examining cognitive disorders in hereditary spastic paraplegia type 4

Cognitive Disorders and Metabolism in 18-FDG- PET in Hereditary Spastic Paraplegia Type 4 (SPG4)

Observational Central Hospital, Nancy, France · NCT06260982

This study is trying to see how hereditary spastic paraplegia type 4 affects thinking and memory by looking at brain scans and comparing them with tests and genetic information from people with the condition.

What this trial studies

This observational study aims to characterize cognitive impairments associated with hereditary spastic paraplegia type 4 using 18-FDG-PET metabolic imaging. The primary objective is to identify specific patterns of cognitive dysfunction in affected individuals. Additionally, the study will explore correlations between neuropsychological assessments, clinical evaluations, imaging data, and genetic information. By understanding these relationships, the research seeks to provide a clearer picture of the cognitive aspects of this condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with a pathogenic variant in the SPAST gene living in the Grand Est region of France.

Not a fit: Patients with dementia or cognitive disorders unrelated to hereditary spastic paraplegia type 4 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of cognitive disorders in patients with hereditary spastic paraplegia type 4, leading to better diagnosis and management strategies.

How similar studies have performed: While cognitive disorders in hereditary spastic paraplegia have been noted, this specific approach using 18-FDG-PET imaging is relatively novel and has not been extensively tested in prior studies.
