First, the GP will try to rule out any underlying physical or mental causes of the symptoms – many of which can be treated – such as:

· depression

· anxiety

· vitamin deficiency

· diabetes

· hormonal conditions

· menopause

The GP will ask about the person’s symptoms, when they started, how they affect their daily life, and their family medical history.

It is a good idea to keep a record of symptoms for a few weeks to show the GP.

It is also helpful for a family member or friend to go to the appointment with the person so they can talk about any changes they have seen.

The GP is likely to carry out a short memory and concentration test. This may include:

· stating the day, date and year

· naming pictures of common objects, eg keys, kettle

· remembering and repeating a list of items

· completing a simple drawing, eg putting numbers on a clock face

The GP should also arrange blood tests, an ECG (a check of heart rhythm) and a head scan.

If other causes of the person’s symptoms are ruled out, the GP should refer them to a specialist memory clinic for more detailed assessments and further scans such as an MRI or CT scan to look for changes in the brain.
