There are by 2009 approximately 246 memory clinics but there are no official NHS figures and no specific standards or set models relating to them.
The National Institute for Health and Care Excellence (NICE) provide guidelines (CG42) which identify the recommended interventions and approaches to assessing a person who is referred to a memory service.
This means that clinics across the Uk differ in how they assess and the type of professionals who staff the memory service.
Assessments are performed by mental health nurses, psychiatrists, occupational therapists and psychologists.
There is also the use of a semi structured interview which gathers information about an individual's experience of memory problems, and the onset and progression of any difficulties with cognitive functioning, activities of daily living and behaviour.
