Mental fatigue is one of the most significant post-traumatic brain
injury symptoms. It is currently not possible to objectively identify.
This study investigated whether a complex computer cognitive test with load on
endurance, processing speed and attention were more demanding for participants
suffering from mental fatigue after brain injury compared with a control group.
METHOD: Seventy-six subjects of mild traumatic brain injury (mTBI) and 45 healthy
controls were included in the study. All subjects with mTBI had been suffering
from mental fatigue for six months or more. Mental fatigue was screened using the
Mental Fatigue Scale (MFS). Cognitive function was measured for information
processing speed and working memory, and with a novel computer test. RESULTS: The
mTBI group rated MFS significantly higher than the control group. The results
revealed a significantly slower information processing speed for the mTBI
subjects and a poorer performance on the working memory test. The computer test
revealed a less efficient performance over time for the TBI subjects compared to
the control group. CONCLUSIONS: The results indicate a less efficient performance
over time in complex and demanding cognitive tasks for individuals experiencing
from mental fatigue after brain injury.
