Effect of Early Memantine Administration on Outcome of Patients With Moderate to Severe Traumatic Brain Injury

Effect of Early Memantine Administration on Outcome of Participents with Moderate to Severe Traumatic Brain Injury

Studying the effect of memantine on platelet, platelet/lymphocyte ratio (PLR) and C reactive protein (CRP) & serum NSE levels in participents with moderate to severe TBI as well as outcome.

Investigators evaluate prognostic effect of memantine on participents with moderate to severe TBI. also to estimate which of platelet, platelet/lymphocyte ratio (PLR), C reactive protein (CRP) or serum NSE levels will be affected by administration of memantine in participents with moderate to severe TBI as a predictor of outcome.
