Which is a symptom of dialysis disequilibrium syndrome (DDS)?

Dialysis disequilibrium syndrome (DDS) is a rare but serious complication that can occur during or after hemodialysis, characterized by a rapid imbalance of solutes and fluids between the blood and cerebral spinal fluid. One of the hallmark symptoms of DDS is blurred vision, which can occur due to fluctuations in osmotic gradients and changes in brain fluid levels. This symptom points to the neurologic effects that can arise from the rapid changes in solute concentrations, particularly affecting the eyes and vision.

In addition to blurred vision, patients may also experience a range of other symptoms associated with DDS, such as headache, nausea, or hypotension. However, blurred vision specifically highlights the changes occurring in the central nervous system, making it a distinct symptom of this condition. Understanding DDS and its symptoms is crucial for healthcare providers to identify and manage this syndrome effectively during hemodialysis treatments.
