BACKGROUND: Mental fatigue is one of the most significant post-traumatic brain
injury symptoms. It is currently not possible to objectively identify.
OBJECTIVE: 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.
