Yes. Some people with Alzheimer's disease who learned English later may gradually understand or use mainly their first language, but this change is not universal. For new care staff, the key task is to identify the person's current preferred language and communication method, then use them consistently. Treat language switching as a communication change—not deliberate misbehavior.

What does "switching back" mean?
"Switching back" means a person begins using or understanding their first-learned language more than a later language. The National Institute on Aging describes this as a recognized communication change in some people with Alzheimer's disease. National Institute on Aging guidance The change may involve speaking, understanding, naming objects, or following instructions.
It can develop gradually, and the person may use more than one language depending on the situation. Do not assume that every bilingual resident will revert to a first language. The Alzheimer's Association lists this among possible communication changes, while stressing that changes differ by person and disease stage. Alzheimer's Association communication guidance.
Is the first language always best preserved?
No. A first language may become the main language, but it is not always the person's strongest language for every task.
In a clinical cohort of 74 sequential bilingual patients with probable Alzheimer's disease, informants reported that 66 people—89.2%—had gradually shifted to predominant or exclusive use of their first-learned language. Mendez and colleagues' clinical study However, another study of 29 Spanish-English bilingual people with Alzheimer's disease found that some could name pictures in their nondominant language when they could not name them in their dominant language. Staff should test communication preferences rather than rely on assumptions about which language dementia has affected least.
What should new staff document?
Use the resident's current abilities, not ethnicity, immigration history, name, or an old chart entry. Ask the resident, family, familiar staff, and language professionals which language works best for specific tasks.
Record practical details, such as: CMS guidance says the care plan should identify the resident's language and available communication tools. It also says all interacting staff, including temporary staff, must know and consistently use those supports for routine care, pain, condition changes, and refusal. CMS State Operations Manual, Appendix PP.
- Preferred spoken language for conversation and personal care
- Languages the resident understands, reads, or uses for familiar words
- Helpful gestures, pictures, objects, or communication boards
- How the resident expresses pain, refusal, discomfort, and basic needs
- Whether the resident responds better to a familiar person, setting, or routine
How can staff communicate at the bedside?
Start with one-to-one conversation in a quiet space. Speak slowly and clearly, ask one question at a time, and allow extra time for a response. Use short, step-by-step instructions supported by gestures, objects, pictures, or demonstrations.
For example, show a towel while saying the equivalent of "wash your face," rather than giving several instructions at once. Avoid correcting, arguing, or demanding that the resident use English. If words fail, observe facial expression, gestures, body movement, and changes from the person's usual behavior. Confirm important information through the resident's established communication supports.
When is professional language assistance needed?
Facilities should arrange competent language assistance when staff cannot communicate reliably with a resident. CMS long-term-care guidance recommends credentialed medical interpreters, available in person, by phone, or by video, along with visual aids and staff training. Do not use an untrained interpreter for important information simply because that person speaks the language.
Family members or bilingual staff may offer useful background, but the facility still needs a dependable method for communicating care, symptoms, changes in condition, and refusal. Also check hearing and vision. The Alzheimer's Association notes that hearing or eyesight loss can compound dementia-related communication difficulty, so not every communication failure results from language switching. Regular hearing and eyesight checks may improve communication.
