Intermingle of astrocytic processes with oligodendrocytes, meningeal cells, microglia and fibroblasts gradually develop into a scar-like structure, which has long been implicated as a major physical impediment to axonal regeneration and counteracts TBI recovery (Fawcett and Asher, 1999). Change in sleep patterns. Neurological presentation of Diffuse Axonal Injury includes bilateral neurological examination deficits frequently affecting the frontal and temporal white matter, corpus callosum, and brainstem. This is called intracranial pressure (ICP) monitoring. In the initial stages following traumatic brain injury, careful handling is essential when assessing patients, especially if they are in a minimally conscious state.

Loss of consciousness. Repeated nausea and vomiting.
Improve lighting in the home, especially around stairs. We propose that the term concussion should be avoided. Exogenous VEGF, for instance, increases astrocytic response, promotes angiogenesis and enhances neurogenesis in experimental model of TBI through the activation of Akt pathway and the Raf/MEK/ERK cascade (Wu et al., 2008; Thau-Zuchman et al., 2010; Lu et al., 2011).
