Clinical Trial Summary

This research relates to the study of cognitive deficits related to various focal brain lesions and their localizations in the brain.

it involves building a large database of behavioural responses measured during the performance of cognitive tasks in patients with focal brain injury, to allow to better understand function of brain.

Description:

The study of patients with focal lesions is at the origin of many key discoveries in the field of neurology and cognitive neuroscience.

There are many mechanisms of injury in the brain. The investigators focus on delineated lesions (as opposed to panencephalic, infectious or traumatic lesions), including stroke, excision of intracranial expansive processes or cortectomies of epileptogenic foci.

At the CHUGA, several hundred patients are hospitalized each year for stroke, several dozen patients are operated on brain tumor and about thirty patients benefit from surgical treatment for their epilepsy.

Post-injury cognitive disorders represent a large heterogeneous class of neurological disorders. They are differentiated by various clinical and neuropsychological profiles involving different higher functions such as attention, language, memory, decision-making or executive functions. This variability observed in these disorders complicates their characterization. Especially, there is no, on a sufficiently large scale, data collection to establish whether cognitive deficits are explained by the relative contribution of the type of test used, the location of the lesion, the nature of the pathology and the post-injury delay. This requires a large cohort of patients.

The objective of this project is precisely to build a structure-function database in patients with focal brain injury (post-stroke or post-cortical resection), with the aim of conducting a transnosographic and longitudinal study of brain functions in these patients. To the knowledge of the investigators, this type of approach has not yet been proposed. Such a project should eventually lead to a better understanding of the nature of the cognitive deficits observed in different types of lesions, and to refine the correlations between structures and functions. This project is in line with the objectives set by the University Hospital Federation NeuroPsyNov, which was labeled in 2015 (Dir P. Kahane, fhu-neuropsynov.chu-grenoble.fr) and aims to encourage transnosographic and translational studies of neurological and psychiatric diseases.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Behavioral performance during cognitive tasks: Exploratory	Behavioral performance during cognitive tasks evaluating attention, memory, language, executive functions and decision-making (reaction time, error rate, modeling parameters): Aggregated data depending of patient disorders linked to the localization of brain lesion and susceptible to evolve in the time (next 10 years).	Data collection will be done on one or more routine visits at 3, 6, 12 or 24 months post lesion (so a maximum of four two-hour sessions)
Secondary	Behavioral performance (reaction time, error rate, modeling parameters): Exploratory	Behavioral performance (reaction time, error rate, modeling parameters) for a given localization according to the pathology and the delay relative to the initial event (lesion) (3, 6, 12, 24 months).	Data collection will be done on one or more routine visits at 3, 6, 12 or 24 months post lesion (so a maximum of four two-hour sessions)
