10.9.4 Dementia
10.9.4.1 Diagnosed and Modelled Prevalence
The prevalence of dementia is given in section 10.9.3.1 on page 667 for each general
practice in Hull for 2009/10. Table 333 presents the prevalence of dementia for
2009/10 for Hull and comparator areas (see section 3.3.3 on page 44), as well as for
England. Hull is relatively more deprived than England and most of the comparators,
and with higher premature mortality rates and the younger population in Hull compared
to the national distribution, it is perhaps not surprising that Hull‟s prevalence of dementia
is lower than England as the highest prevalence will occur in the oldest age groups (e.g.
85+ years). However, if the prevalence of dementia was associated with deprivation,
then this would counter-balance this argument to some extent.

The number of patients with diagnosed dementia and the prevalence as recorded on the
GP QOF disease registers over time is illustrated in Table 334 for 2006/07 to 2009/10
(the registers were introduced during 2004/05 but the dementia measure was introduced
2006/07). The latest list size refers to the registered population as at 1 st January 2010,
but the number and prevalence on the disease register is as at 31 st March 2010 (the
same definitions used in QOF), and this means that the prevalence can be biased if
large population changes have occurred over this three month period (e.g. Y02747,
Y02786, Y02896 and Y02748 all opened between 5 th October 2009 and 11 th January
2010). The latest list size for B81668 (Dr EG Stryjakiewicz) relates to 2006/07. Some
practices were not in existence for all the years so information is not applicable (N/A).
