Brief summary

PatiEnt Neuropsychological outcomeS After laseR ablation

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.

Interventions

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.

MeasureTime frameDescription
Site-determined Cognitive Changes Per DomainAt least six months from baseline assessment. Subjects were analyzed even if they only had 1 test performed. The baseline test information can still be used even if they didn't have follow up testing done.Neuropsychological test data collected will 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 (Boston Naming Test), Executive Function (Trails Making Test), Attention (Wechsler Adult Intelligence Scale 3 Digital Span Test), Verbal Memory (Logical Memory Test), Visual Memory (Brief Visiospacial Memory Test), Verbal Fluency (Animal Fluency Test), and Motor Function (Grooved Pegboard Test).

Site-determined Cognitive Changes Per Domain

Neuropsychological test data collected will 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 (Boston Naming Test), Executive Function (Trails Making Test), Attention (Wechsler Adult Intelligence Scale 3 Digital Span Test), Verbal Memory (Logical Memory Test), Visual Memory (Brief Visiospacial Memory Test), Verbal Fluency (Animal Fluency Test), and Motor Function (Grooved Pegboard Test).

Time frame: At least six months from baseline assessment. Subjects were analyzed even if they only had 1 test performed. The baseline test information can still be used even if they didn't have follow up testing done.

Population: Subjects who had LITT and completed baseline and follow-up testing.
