Cognitive Disorders in Hereditary Spastic Paraplegia Type 4

Recruiting
Conditions
Spastic Paraplegia
Registration Number
NCT06260982
Lead Sponsor
Central Hospital, Nancy, France
Brief Summary

Hereditary spastic paraplegia type 4 is the most frequent mutation of hereditary spastic paraplegias. It is commonly described as pure, with progressive weakness of the lower limbs, pyramidal syndrome and vesico-sphincter disorders. However, cognitive disorders have been reported for over 20 years, but remain poorly characterized.

Detailed Description

Our primary objective is to describe a pattern of cognitive impairment in Hereditary Spastic Paraplegia type 4 using 18-FDG-PET metabolic imaging.

As secondary objectives, we wish to study the presence of correlations between neuropsychological tests, clinical examination, 18-FDG-PET data and general and genetic data of the pathology. We also wish to investigate correlations between genotype and phenotype.
