DISEASES OF THE NERVOUS SYSTEM (G00-G99)

Diseases of the nervous system (G00-G99) accounted for 5,961 registered deaths in 2008, representing 4.1% of all registered deaths. This follows a gradual increase in deaths attributable to Diseases of the nervous system over time, from 3,890 in 1999. The number of deaths due to Diseases of the nervous system was higher for females (3,237) than for males (2,724). The median age at death was 80.0 for males, 84.4 for females.

Deaths from Alzheimer's disease (G30) constituted 42% (2,483) of all deaths due to Diseases of the nervous system and 1.7% of all registered deaths in 2008. Female deaths (1,692) due to Alzheimer's disease were much higher than male deaths (791), with a ratio of 47 male deaths per 100 female deaths. The median age at death due to Alzheimer's disease was 86.8 years.

Parkinson's disease (G20) accounted for 22% of all deaths due to Diseases of the nervous system and 0.9% of all deaths registered in 2008. There were 1,284 deaths due to this disease, with a median age at death of 83.2 years. The number of male deaths (752) due to this disease was higher than the number of female deaths (532). This was similar to the overall trend for the past 10 years.

(a) Causes selected are those with 20 or more deaths at the 3 digit level of ICD-10.
(b) 2008 data have been subject to process improvements which have increased the quality of these data. See Technical Note 1: 2008 COD Collection - Process Improvements for further information.
(c) Causes of death data for 2008 are preliminary and subject to a revisions process. See Technical Note 2: Causes of Death - Revisions Process.
(d) Data cells with small values have been randomly assigned to protect the confidentiality of individuals. As a result, some totals will not equal the sum of their components. It is important to note that cells with a zero value have not been affected by confidentialisation.
