Apneic spells in progressive dialysis encephalopathy

Area of Science:

• Neurology
• Nephrology
• Critical Care Medicine

Background:

• Dialysis encephalopathy is a neurological complication associated with chronic kidney disease and dialysis.
• Previous descriptions of dialysis encephalopathy primarily focused on cognitive and motor deficits.

Observation:

• A 53-year-old patient presented with progressive dialysis encephalopathy.
• The patient exhibited episodic EEG abnormalities characteristic of the syndrome.
• The patient experienced sudden respiratory arrest spells.

Findings:

• The respiratory arrest episodes were in close temporal association with the abnormal EEG findings.
• This suggests a potential link between the specific EEG abnormalities and respiratory control in dialysis encephalopathy.

Implications:

• This observation expands the known clinical spectrum of dialysis encephalopathy.
• It highlights the importance of monitoring respiratory function in patients with this condition.
• Further research may elucidate the neurophysiological mechanisms underlying respiratory arrest in dialysis encephalopathy.
