Caring for people with Alzheimer's disease using the conceptual model of progressively lowered stress threshold in the clinical setting.

Care of the people with Alzheimer's disease and related disorders (ADRD) has been fraught with controversy, often resulting in competing philosophies about what constitutes the "correct" approach. Whether developing an individualized plan of care or specialized programming, it is helpful to use a conceptual framework. The Progressively Lowered Stress Threshold (PLST) conceptual model has been used extensively for planning individualized care for patients with ADRD, developing specialized environments and programming, evaluating outcomes of interventions, and serving as the theoretical framework for nursing research. This article describes use of the PLST model in a clinical setting.
