What symptom did Keenan's wife report that indicates possible complications related to his chronic kidney disease?

In the context of chronic kidney disease (CKD), increased confusion can be indicative of several underlying issues related to the progression of the disease. One significant concern in CKD is the buildup of toxins in the bloodstream due to the kidneys' diminished ability to filter waste. This accumulation can impact cognitive function, leading to symptoms such as confusion or altered mental status.

Additionally, patients with CKD may experience an imbalance in electrolytes, such as sodium and potassium, which can also contribute to neurological symptoms, including confusion. It is important for caregivers and family members to be aware of these changes as they can signify worsening kidney function or the development of complications such as uremic encephalopathy, which is a serious condition that requires immediate medical attention.

Understanding this symptom helps in recognizing the seriousness of kidney disease and the need for timely intervention to manage complications effectively. Other symptoms listed, while they may be relevant to different health concerns, do not specifically relate to the cognitive effects that can arise from CKD-related complications.
