What possible causes of cognitive impairment could a technician share with the family of a patient undergoing dialysis?

Uncontrolled high blood pressure is a significant factor that can contribute to cognitive impairment in patients, particularly those who are undergoing dialysis. Hypertension can lead to changes in blood flow to the brain, affecting cognitive functions such as memory, attention, and problem-solving. In patients with kidney issues, uncontrolled hypertension worsens the overall health and can lead to a range of complications, including stroke and vascular dementia, which further exacerbate cognitive decline.

While advanced age, low red blood cell counts, and intradialytic hypotension can also influence cognitive function, uncontrolled high blood pressure is directly linked to the vascular health that impacts cognition. Age is a risk factor but does not provide the immediate context relevant to a patient's current health status, and low red blood cell counts may lead to anemia-related cognitive effects, particularly if anemia is severe. Intradialytic hypotension can cause temporary symptoms during dialysis sessions but is often managed effectively and does not carry long-term implications compared to the persistent risks posed by uncontrolled hypertension.
