In simple terms
How to tell everyday age-related forgetfulness from changes that need assessment, and what protects the brain.
What is usual with age
- Taking longer to recall a name, then remembering it later
- Occasionally forgetting an appointment but managing the diary
- Being more easily distracted in noisy places
What deserves assessment
- Repeating the same question within a short conversation
- Getting lost on a familiar route
- Difficulty with familiar tasks: cooking a known recipe, handling money
- Family noticing changes in personality, judgement or withdrawal
Reversible causes to rule out first
Thyroid problems, vitamin B12 deficiency, depression, poor sleep or sleep apnoea, alcohol and some medicines can all mimic memory disease. A simple check-up can find them.
What protects the brain
- Blood pressure, blood sugar and hearing well managed
- Regular physical activity, most days
- Social contact and mentally demanding hobbies
- Treating hearing loss: hearing aids reduce cognitive strain
When to seek medical help
Ask for a memory assessment if daily independence is affected, or if changes appear over months rather than years.
