Reading of the Week: Coffee & Dementia Risk – the New JAMA Paper; Also, Mental Healthcare and Till on Her Son & His Illness

Many of us enjoy drinking coffee before a busy afternoon clinic. Is that cup of java actually healthy? Do caffeinated beverages like coffee and tea reduce the risk of dementia?

Smaller studies have suggested that they do reduce risk; a meta-analysis of coffee drinkers had a similar finding. In an impressive, new JAMA paper, Yu Zhang (of Harvard University) and his co-authors attempt to answer these questions. They report on a prospective cohort study involving almost 132 000 people, looking at dementia risk with a follow-up period up to 43 years. They found a reduction of about 18%. “Greater consumption of caffeinated coffee and tea was associated with lower risk of dementia and modestly better cognitive function, with the most pronounced association at moderate intake levels.” We consider the paper and its implications.

A cup (or two) a day keeps the doctor away?

It’s the paradox of modern psychiatry. Our medications and therapies have never been better, yet access remains poor and quality is uneven, in part because there is no mental health “system.” So, what can be done? In the second selection, from the podcast series Quick Takes, I sit down with Dr. Paul Kurdyak. In addition to being the longest serving ED psychiatrist at CAMH, he is the Vice-President, Medical, of Ontario Health’s Mental Health and Addictions Centre of Excellence. “Good systems just work. They don’t need to be navigated.”

And in the third selection, Madeline Till, a psychotherapist, writes about the struggles of her son, who has schizophrenia. In a New York Times essay, she wonders whether it would be easier if he had cancer. “More than anything else I have ever wanted, I want to stop this revolving door. I want schizophrenia to be treated with the same urgency, seriousness and continuity as any other life-threatening illness.”

Reading of the Week: Cannabis-Related Disorders – the new NEJM Paper; Also, Surgeons & Opioid Prescribing and MAiD & Mental Illness

February 8, 2024 /

From the Editor

Cannabis use is increasingly common. Should you be screening for misuse? What’s the role of drug testing? Do short interventions work?

In the first selection, we look at the new paper on cannabis-related disorders, published in The New England Journal of Medicine. Dr. David A. Gorelick (of the University of Maryland) comments on cannabis use disorder, offering practical suggestions, drawing on the latest in the literature (with 76 references). “Cannabis use disorder and heavy or long-term cannabis use have adverse effects on physical and psychological health.” We discuss the paper and its takeaways.

In the second selection, Jason Zhang (of the University of Michigan) and his co-authors consider surgeons and the prescribing of opioids. Given past problems, are surgeons more frugal when they reach for the prescription pad? Drawing on an impressive US database, they analyzed dispensed opioids from 2016 to 2022 in a new JAMA Network Open research letter, finding a step in the right direction – but just a step. “Despite large reductions in opioid prescribing, surgical opioid stewardship initiatives remain important.”

And in the third selection, The Globe and Mail weighs in on the recent decision to delay the expansion of medical assistance in dying, or MAiD, for mental disorders. In an unsigned editorial, the authors recognize the suffering of some, but argue that not enough has been done to define the term irremediable. “A delay is not enough.”
