Meet the whole teamPrivate assessment alongside the NHS
A private assessment is a different route to a diagnosis. It does not replace your GP or the NHS.
With your consent, we send your report, diagnosis and care plan to your GP, so your care can continue through the NHS or privately.
NHS memory assessment services are free to use, and waiting times vary by area.
