Quick answer
Do sleep disorders affect ketamine therapy?
Untreated severe sleep apnea raises perioperative risk and warrants disclosure. Insomnia is common in patients seeking ketamine therapy and can shift after sessions — sometimes improving, sometimes briefly disrupted. Disclose all sleep concerns at screening.

Sleep apnea

Severe untreated obstructive sleep apnea increases perioperative respiratory risk. Patients on CPAP should report this; some clinics request a recent sleep study.

Insomnia

Ketamine response often improves sleep over weeks. Some patients have temporarily disrupted sleep the night of a session.
