Traumatic brain injury (TBI) is a serious healthcare problem, and this report is
a selective review of recent findings on the epidemiology, pathophysiology and
neuropsychological impairments following TBI. Patients who survive
moderate-to-severe TBI frequently suffer from a wide range of cognitive deficits
and behavioral changes due to diffuse axonal injury.
These deficits include
slowed information-processing and impaired long-term memory, attention, working
memory, executive function, social cognition and self-awareness. Mental fatigue
is frequently also associated and can exacerbate the consequences of
neuropsychological deficits. Personality and behavioral changes can include
combinations of impulsivity and apathy. Even mild TBI raises specific problems:
while most patients recover within a few weeks or months, a minority of patients
may suffer from long-lasting symptoms (post-concussion syndrome). The
pathophysiology of such persistent problems remains a subject of debate, but
seems to be due to both injury-related and non-injury-related factors.
