[Posttraumatic cerebrasthenia and posttraumatic encephalopathy--difficulties in opinionating]

Post-traumatic cerebrasthenia and post-traumatic encephalopathy are the effects of a head trauma. Most physicians overuse these diagnoses. They do not perform differential diagnostic management, what leads to issuing erroneous opinions. The aim of this report is to show the symptoms of posttraumatic cerebrasthenia and posttraumatic encephalopathy and diagnostic investigations, which could be helpful for diagnosing these conditions. Cerebrasthenia (the subjective posttraumatic syndrome, subjective syndrome, posttraumatic neurosis) is usually a functional--"unorganic" disorder. It happens in the cases of many people who had brain concussion. The most common symptoms are: headache, vertigo, irritability, insomnia, attention deficits, fatigability. Posttraumatic encephalopathy is a persistent brain tissues injury which could be caused by more severe trauma (brain contusion, endocranial bleeding). The clinical picture of this disease entity is not unambiguous. The most frequently encountered form is a simple (common) form, which is similar to cerebrasthenia, but with differences in the neurological examination (focal signs) and with persistent changes in EEG.
