Which of the following is NOT a sign of dialysis dementia?

Dialysis dementia, often referred to in the context of cognitive changes seen in patients undergoing long-term dialysis, typically presents with a range of psychological and cognitive symptoms. Common signs include speech problems, personality changes, and confusion. These symptoms result from the accumulation of toxins in the brain due to impaired renal function and the effects of hemodialysis on the central nervous system.

While frequent headaches can occur in patients undergoing dialysis, they are not a specific hallmark or defining feature of dialysis dementia. Headaches can arise from various causes unrelated to cognitive decline or dementia, such as dehydration, electrolyte imbalances, or other medical conditions. Therefore, recognizing that headaches do not directly associate with the cognitive impairments indicative of dialysis dementia clarifies why they are not considered a sign of this condition.
