DISEASES OF THE NERVOUS SYSTEM (G00-G99)
Diseases of the nervous system (G00-G99) accounted for 5,467 registered deaths in 2007, representing 4.0% of all registered deaths. This follows a gradual increase in deaths attributable to Diseases of the nervous system over time, from 3,717 in 1998. The number of deaths due to Diseases of the nervous system was higher for females (2,956) than for males (2,511). The median age at death was 79.3 years for males, 84.1 years for females.
Deaths from Alzheimer's Disease (G30) constituted 42% (2,272) of all deaths due to Diseases of the nervous system and 1.6% of all registered deaths in 2007. Female deaths (1,543) due to Alzheimer's Disease were much higher than male deaths (729), with a ratio of 47 male deaths per 100 female deaths. The median age at death due to Alzheimer's Disease was 86.4 years.
Parkinson's Disease (G20) accounted for 20% of all deaths due to Diseases of the nervous system and 0.8% of all deaths registered in 2007. There were 1,109 deaths due to this disease, with a median age at death of 82.7 years. The number of male deaths (672) due to this disease was higher than the number of female deaths (437). This was similar to the overall trend for the past 10 years.
