Brief Summary:
PatiEnt Neuropsychological outcomeS After laseR ablation

Condition or disease Intervention/treatment
Cognitive Change Device: Neuroblate System

Detailed Description:
This is a multicenter sub-study that will include comprehensive neuropsychological assessment data collection done at baseline (within 1 year prior to the index LITT procedure) and at follow-up (at least 6 months from the index LITT procedure). Visual field testing will be conducted in a subset of enrolled patients. Up to 250 subjects may be enrolled at up to 15 study sites.

Study Type : Observational [Patient Registry]
Estimated Enrollment : 250 participants
Observational Model: Cohort
Time Perspective: Cross-Sectional
Target Follow-Up Duration: 5 Years
Official Title: PatiEnt Neuropsychological outcomeS After laseR Ablation
Actual Study Start Date : September 29, 2021
Estimated Primary Completion Date : December 2024
Estimated Study Completion Date : December 2024

Intervention Details:
  • Device: Neuroblate System

    All subjects will undergo comprehensive neuropsychological assessment post-LITT per standard of care practice.

    Visual field testing will be conducted in a subset of enrolled patients.

Primary Outcome Measures :
  1. Site-determined cognitive changes per domain [ Time Frame: At least six months from baseline assessment ]
    Neuropsychological test data will be collected for all study participants to describe cognitive domain specific changes as a cohort. Change will be assessed from raw test scores and demographically corrected standardized scores (where available). For this study, collected cognitive domains include Language, Executive Function, Attention, Verbal Memory, Visual Memory, Verbal Fluency, and Motor Function.

Secondary Outcome Measures :
  1. Change in raw test scores from standard battery of preferred neuropsychological tests [ Time Frame: At least six months from baseline assessment ]
    Describe the observed change or stability of neuropsychological test scores in patients who underwent laser ablation surgery. Change will be assessed from raw test scores and demographically corrected standardized scores (where available). For this study, tests include Boston Naming, Trails making Test A and Test B, Digit Span, Logical memory test (subtest from Wechsler Memory Scale IV), BVMT--Brief Visuospatial Memory Test, Animal Fluency test, and Grooved Pegboard.

  2. Incidence of visual field deficits in patients with MTLE [ Time Frame: At least six months from baseline assessment ]
    Visual field testing using Humphry automated fields (HVF 24-2 SITA standard) will be conducted for a subset of patients to identify visual field deficits resulting after the LITT procedure.
