Impact of anticholinergic burden on cognitive impairment, disability and malnutrition: a cross-sectional study among hospitalized older patients

The anticholinergic burden (ACB) is known to be associated with the worsening of functional and cognitive status. This study aims at demonstrating a correlation between the ACB and the malnutrition, given the widespread effect on the digestive tract of anticholinergic medications.
