This week begins with a review of the latest internet gaming disorder research, a case report of tapentadol-induced hallucinations, and a novel way to identify face blindness.

The Journal of Clinical Psychiatry just released new data that shows that ketamine once again offers a ray of hope for veterans suffering from depression.

Clinical Outcomes of IV Ketamine for Depression

Short-term clinical trials found intravenous (IV) ketamine to be effective in reducing depressive symptoms. This study assessed longer-term outcomes of IV ketamine for depression and explored treatment and patient factors that may affect results.

Records of IV ketamine infusions for depression and associated Patient Health Questionnaire-9 (PHQ-9) scores were identified from Veterans Health Administration (VA) electronic medical records for patients treated in Fiscal Year 2020 and up to 12 months following the date of their first infusion.

And while only a minority of patients treated with IV ketamine for depression experienced response or remission, symptom improvements achieved within the first 6 weeks were sustained over at least 6 months with decreasing infusion frequency. Further study is needed to determine optimal infusion frequency and potential for adverse effects with repeated ketamine infusions for depression.
