Memory loss is the most well-known symptom of dementia, particularly Alzheimer’s disease. But experts say there are other warning signs that can signal early brain changes — ones that are especially important for types of dementia where forgetfulness is not the primary symptom. Just like occasional lapses in memory, these issues can also be attributed to other age- or health-related changes (or just a bad day), so experts emphasized that they aren’t necessarily red flags for dementia in isolation. But, especially in combination, they might be a sign that it’s time to see a doctor.
