6 month follow up with Neuropsychological data Screening Module of the Neuropsychological Assessment Battery-SNAB
- Attention: 56.7% of the patients remained impaired at 6 months post-trauma, 3.33% worsened, and the remaining improved or remained unaffected.
- Language Function: 63.3% of patients remained impaired, 26.7% improved, 6.67% remained unaffected, and 3.33% worsened.
- Memory: 33.3% of patients remained impaired within the domain of memory 6 months post-trauma with essentially equivocal changes (26.7% worsened, 26.7% remained unaffected, and 13.3% with improved memory status).
- Spatial Functioning: 53.3% remained unaffected for spatial function, although 23.3% showed signs of delayed impairments in the chronic phase.
- Executive Functioning: 70.0% of the subset patient group remained impaired with respect to executive functioning, with only 20.0% of these patients showing signs of improvement or recovery after the 6-month period post-trauma.
