it can be influenced by nutritional choices.
up until now there is no known cure for it.
it can be contracted through germs.

Answer 1

Here’s a short evaluation of each statement plus brief context and practical points.

1) "Alzheimer's disease has some lifestyle factors because everyone can contract it in their lifetime."
- Partly true / partly false. Alzheimer’s risk is influenced by a mix of non‑modifiable (age, genetics such as APOE4) and modifiable lifestyle and vascular factors (physical activity, smoking, blood pressure, diabetes, hearing loss, social and cognitive activity, diet). However, it is not true that “everyone” will get Alzheimer’s; risk increases with age but most older people do not develop the disease.

2) "It can be influenced by nutritional choices."
- True. Diet appears to influence risk: patterns such as Mediterranean, DASH or MIND diets are associated with lower dementia risk in many studies. Nutrients and eating patterns that reduce cardiovascular risk (healthy fats, vegetables, whole grains, limited processed foods and sugar) are generally recommended. Evidence is still evolving and no specific food or supplement is a proven guaranteed prevention.

3) "Up until now there is no known cure for it."
- True. There is no cure that reverses Alzheimer’s. Treatments exist that can modestly improve symptoms or slow decline in some people (cholinesterase inhibitors, memantine, and some anti‑amyloid monoclonal antibodies shown to reduce amyloid burden and marginally slow progression in selected patients), but none restore normal brain function or eliminate the disease.

4) "It can be contracted through germs."
- False in the usual sense. Alzheimer’s is not a contagious infection you “catch” from another person. There is research exploring whether chronic infections (e.g., herpes viruses, oral bacteria) or inflammatory responses may contribute to risk, but that does not mean Alzheimer’s is transmitted like a viral or bacterial disease. Very rare and specific laboratory/iatrogenic findings (related to prion-like seeding in unusual circumstances) do not imply ordinary person-to-person contagion.

If you want, I can:
- Summarize practical, evidence‑based ways to lower dementia risk.
- Point to reliable sources (WHO, Lancet Commission, Alzheimer’s Association) for further reading.
