In a subgroup of patients, traumatic brain injury (TBI) results in the occurrence of acute epileptic seizures or even status epilepticus, which are treated with antiepileptic drugs (AEDs). Recent experimental data, however, suggest that administration of AEDs at the early post-injury phase can compromise the recovery process. The present study was designed to assess the profile of a novel anticonvulsant, lacosamide (Vimpat) on post-TBI structural, motor and cognitive outcomes. Moderate TBI was induced by lateral fluid-percussion injury in adult rats. Treatment with 0.9% saline or lacosamide (30 mg/kg, i.p.) was started at 30 min post-injury and continued at 8h intervals for 3d (total daily dose 90 mg/kg/d). Rats were randomly assigned to 4 treatment groups: sham-operated controls treated with vehicle (Sham-Veh) or lacosamide (Sham-LCM) and injured animals treated with vehicle (TBI-Veh) or lacosamide (TBI-LCM). As functional outcomes we tested motor recovery with composite neuroscore and beam-walking at 2, 7, and 15 d post-injury. Cognitive recovery was tested with the Morris water-maze at 12-14 d post-TBI. To assess the structural outcome, animals underwent magnetic resonance imaging (MRI) at 2 d post-TBI. At 16d post-TBI, rats were perfused for histology to analyze cortical and hippocampal neurodegeneration and axonal damage. Our data show that at 2 d post-TBI, both the TBI-Veh and TBI-LCM groups were equally impaired in neuroscore. Thereafter, motor recovery occurred similarly during the first week. At 2 wk post-TBI, recovery of the TBI-LCM group lagged behind that in the TBI-VEH group (p<0.05). Performance in beam-walking did not differ between the TBI-Veh and TBI-LCM groups. Both TBI groups were similarly impaired in the Morris water-maze at 2 wk post-TBI. MRI and histology did not reveal any differences in the cortical or hippocampal damage between the TBI-Veh and TBI-LCM groups. Taken together, acute treatment with LCM had no protective effects on post-TBI structural or functional impairment. Composite neuroscore in the TBI-LCM group lagged behind that in the TBI-Veh group at 15 d post-injury, but no compromise was found in other indices of post-TBI recovery in the LCM treated animals.
