The introduction highlights the shift from traditional treatment to a patient-focused approach, emphasizing the importance of patient and family involvement in clinical decision-making. The case study details the patient's medical, social, and individual history, including the progression of dementia, her caregiving role, and the impact of the disease on her daily life.
