The primary nursing concern for Alzheimer's disease is ensuring safety and maintaining quality of life while managing progressive cognitive decline and behavioral symptoms through person-centered care. Alzheimer's is progressive dementia with memory loss, disorientation, impaired judgment, and eventually loss of basic functions. Nursing interventions: create safe environment (prevent wandering, falls); use communication strategies (simple sentences, nonverbal cues); maintain routines; manage behavioral symptoms (agitation, sundowning) non-pharmacologically first; provide cognitive stimulation appropriate to stage; support caregivers (respite, education). Documentation includes cognitive status, functional abilities, and behavioral symptoms. Patient education for family about disease progression and care strategies. Nurses coordinate with geriatrics, neurology, social work. Medications (cholinesterase inhibitors, memantine) may slow progression temporarily. Advanced stages require total care. Ethical issues include decision-making capacity and end-of-life care. Person-centered care preserves dignity.
