Frequently asked questions

Is memory loss just old age?

Not always. Some causes are reversible, so assessment is worthwhile.

Can family consult on behalf of an elderly patient?

Yes. Family input is essential; the patient can join the video call if possible.

Are sleeping pills safe in old age?

Many increase confusion and falls. Ask before giving any sleeping medicine.
