Brief Summary
In this study, 300 patients aged ≥18 years old with traumatic brain injury (case group) and hospitalized patients without central nervous system disease or their family members and accompanying staff (control group) were selected as the study objects. At baseline, participants completed the Mini-mental State Examination (MMSE), the Loewenston Occupational Therapy Cognitive Assessment (LOTCA) battery, the Glasgow Coma Scale (GCS), and the Alzheimer's Disease Rating Scale Cognitive Subscale (ADAS-Cog11). The evaluation process of the first LOTCA test was videotaped by a person. 2 weeks after the evaluation, the same two scale raters watched the video and rated it independently again. After 3 months, the subjects completed MMSE, LOTCA battery, GCS, ADAS-Cog11 assessment again.
