What is a common neurological disturbance associated with CKD?

1. Memory loss

2. Reduced cerebral blood flow

3. Severe headaches

4. Visual disturbances

The correct answer is: Reduced cerebral blood flow

Chronic Kidney Disease (CKD) can lead to a variety of neurological disturbances, and reduced cerebral blood flow is a significant factor contributing to cognitive impairment and other neurological issues in these patients. CKD often results in an accumulation of uremic toxins in the bloodstream, which can affect the vascular system and impair cerebral perfusion. This reduced blood flow to the brain may lead to symptoms such as confusion, difficulty concentrating, and an overall decline in cognitive function, commonly referred to as "uremic encephalopathy." Additionally, other factors such as hypertension, anemia, and electrolyte imbalances commonly associated with CKD can also contribute to reduced cerebral blood flow, further exacerbating neurological disturbances. Recognizing the relationship between kidney function and cerebral perfusion is essential for managing patients with CKD, particularly in a nephrology setting.
