Recent advances of transcranial electrical stimulation in healthy aging and Parkinson's disease: Effects on dual tasking.

The prevalence of cannabis hyperemesis syndrome (CHS), a condition characterized by cyclical nausea and vomiting associated with frequent cannabis use, increased sharply in the United States during 2016–2022. The proportion of all-cause emergency department visits that involved CHS were higher after implementation of a new diagnosis code, suggesting improved recognition and previous underestimation of the public health impact of CHS. Higher proportions were observed among younger persons and females. The new CHS-specific diagnosis code has improved CHS surveillance and estimation of public health impact. However, increased clinical recognition and education about risks of frequent cannabis use are still needed, particularly in younger populations.
