What are side effects and/or symptoms of someone who suffered from cerebral edema at 1 years of age.  My step son had hit his head falling out of a baby chair onto hard tile floor.  He had neurological evaluations for 6 months and they determined that diagnosis.  My true questions are if heavy sleeping (during day), mood swings, and delusions of granduer are side effects that could have derived from such a trauma that occured many years ago.  Reasoning and logical decsion making is heavily affected as well.
I read your question carefully, and I understand your concern. Cerebral edema means brain swelling, but it's not a specific sign as it can be present in many types of brain lesions. However, considering the length of time he was followed it is obvious that he sustained a brain damage due to the trauma, damage which is permanent, some brain tissue is lost. That traumatic brain impairment can manifest itself with the behavioral symptoms that you describe, it is a common occurrence. Of course that must be correlated with the extent of injury on brain imaging, but it is well possible. I hope to have been of help.
