Abstract

BACKGROUND:

Have USA total neurological deaths (TNDs) of adults (55-74) and the over 75's risen more than in twenty Western Countries?

METHODS:

World Health Organization TND data are compared with control mortalities cancer mortality rates (CMRs) and circulatory disease deaths (CDDs) between 1989-1991 and 2008-2010 and odds ratios (ORs) and confidence intervals calculated.

RESULTS:

Neurological Deaths - Twenty country (TC) average 55-74 male rates per million (pm) rose 2% to 503 pm, USA increased by 82% to 627 pm. TC average females rose 1% to 390 pm, USA rising 48% to 560 pm. TC average over 75's male and female increased 117% and 143%; USA rising 368% and 663%, significantly more than 16 countries. Cancer mortality - Average 55-74 male and female fell 20% and 12%, USA down 36% and 18%. TC average over 75's male and female fell 13% and 15%, the USA 29% and 2%. Circulatory deaths - TC average 55-74 rates fell 60% and 46% the USA down 54% and 53%. Over 75's average down 46% and 39%, USA falling 40% and 33%. ORs for rose substantially in every country. TC average 75's ORs for CMR: TND male and females were 1:2.83 and 1:3.04 but the USA 1:5.18 and 1:6.50. The ORs for CDD: TND male and females TC average was 1:3.42 and 1:3.62 but the USA 1:6.13 and 1:9.89.

CONCLUSIONS:

Every country's neurological deaths rose relative to the controls, especially in the USA, which is a cause for concern and suggests possible environmental influences.
