Life Expectancy n The 20 th century saw a dramatic increase in life expectancy Life Expectancy n The 20 th century saw a dramatic increase in life expectancy from 47 y in 1900 to around 80 y today n Most of this gain can be attributed to improved social conditions and success in preventing and treating major infectious diseases (eg TB) n Further gains will depend on delivering new healthcare advances

Treating Parkinson’s Disease The MRC and Parkinson’s Disease Society have recently funded a £ Treating Parkinson’s Disease The MRC and Parkinson’s Disease Society have recently funded a £ 1. 25 m trial to test the long-term effectiveness of surgery versus drug treatment for Parkinson’s Disease • Parkinson’s Disease is controlled by drugs but these become less effective over time and the period of relief they offer also decreases • Surgery provides longer periods of quality living as opposed to the 1 -2 h that drugs offer, but the long term effects on quality of life of the patient and carer need to be evaluated • The trial is being led from the QE hospital in Birmingham
