Which symptom is associated with dialysis dementia?

Dialysis dementia, also known as dialysis-related cognitive impairment, refers to cognitive decline that may occur in patients undergoing long-term dialysis treatment. One of the symptoms often associated with dialysis dementia is muscle spasms. These spasms can arise due to electrolyte imbalances, particularly a deficiency of calcium or magnesium, which are critical for proper muscle function. The neurological impact of dialysis on patients can lead to changes in cognitive function and potentially result in physical manifestations such as muscle spasms.

The other options listed do not directly correlate with the cognitive issues and neurological symptoms characterized by dialysis dementia. Skin rashes are generally related to other factors such as reactions to dialysis products or infections. Frequent urination could occur in patients with different kidney issues but is not a symptom associated specifically with dementia related to dialysis. Rapid weight gain might reflect fluid overload rather than cognitive changes, and while it is a concern for dialysis patients, it doesn't indicate cognitive impairment akin to dialysis dementia.
