What kind of neurological symptoms are associated with PRES?

The neurological symptoms associated with Posterior Reversible Encephalopathy Syndrome (PRES) primarily include acute confusion and seizures. This condition is characterized by swelling in the brain's posterior regions, which can lead to a rapid onset of neurological issues. Patients often present with altered mental status, which can manifest as confusion, agitation, or changes in consciousness, and seizures are a common neurologic complication due to the edema affecting the brain tissue and the associated electrical activity.

Acute confusion indicates a sudden change in mental state, while seizures represent convulsions caused by abnormal electrical discharges in the brain. These symptoms often arise quickly and may resolve with appropriate management, highlighting the reversible nature of the syndrome.

Other symptoms related to PRES, such as headaches, memory loss, or hallucinations, may occur but are less characteristic or prominent than the acute confusion and seizures. Thus, while those symptoms may sometimes be related to other neurological conditions or occur in other contexts, the defining features of PRES center around the acute neurological changes that lead to confusion and seizure activity.
