[24] The tests have a positive predictive value over 90%, but a negative predictive value less than 50%. The LP should ...
Diagnostic methods for hypertensive encephalopathy include physical examination, blood pressure measurement, blood sampling, ECG, EEG, chest X-ray, urinalysis, arterial blood gas analysis, and imaging of the head (CAT scan and/or MRI). Since decreasing blood pressure is essential, anti-hypertensive medication is administered without awaiting ...
Therefore, the reduced CSF pressure could cause a decrease in Perilymphatic pressure and cause secondary endolymphatic hydrops. [38] In addition to the increased hearing loss, there have also been findings of resolved hearing loss after ventriculoperitoneal shunt placement, where there is a release of CSF pressure on the auditory pathways.
Patients may have a history of loss of consciousness but they recover and do not relapse. Clinical onset occurs over hours. Complications include focal neurologic deficits depending on the site of hematoma and brain injury, increased intracranial pressure leading to herniation of brain and ischemia due to reduced blood supply and seizures.
