Medscape (12/14, Brooks, Subscription Publication) reports a new study now “provides more evidence that antipsychotics that raise prolactin levels are tied to a significantly increased risk for breast cancer.” After identifying “914 cases of invasive breast cancer among 540,737 women,” investigators concluded that “the relative risk for breast cancer was 62% higher in women who took category 1 antipsychotic medications associated with high prolactin levels.” These medications “include haloperidol (Haldol), paliperidone (Invega), and risperidone (Risperdal).” What’s more, “the risk was 54% higher in those taking category 2 antipsychotics that have mid-range effects on prolactin,” such as “iloperidone (Fanapt), lurasidone (Latuda), and olanzapine (Zyprexa).” The findings were published online Dec. 3 in the Journal of Clinical Psychopharmacology.

The New York Times (12/8, MacKeen) reported on prolonged grief disorder (PGD), “a newly recognized condition” that is “a syndrome in which people feel stuck in an endless cycle of mourning that can last for years or even decades, severely impairing their daily life, relationships and job performance.” PGD “isn’t new” but previously “it was listed in the D.S.M. as a condition for further study. Preliminary studies suggest that it affects around 7 percent of those in mourning.” The Times added, “Dr. Vivian Pender, president of the American Psychiatric Association, which publishes the D.S.M., said the prevalence of prolonged grief disorder may increase because of the sheer magnitude of Covid deaths.” Dr. Pender said, “I think the pandemic has made losing someone particularly worse. The usual loss and grieving process has been disrupted.”
