Alzheimer’s Society comment on new findings that higher concentrations of the protein clusterin in the blood could be associated with the development, severity and progression of Alzheimer’s disease.
New research published in Archives of Psychiatry identified the protein in a small study of 95 people. It then measured levels in a sample of 689 participants, including 464 people with Alzheimer’s disease. It found higher levels of the protein in the blood were associated with severity of disease, rapid clinical progression and atrophy of the area of the brain linked to memory.
Alzheimer’s Society comment:
‘This interesting study provides more evidence that the protein clusterin could have an important role to play in the development of Alzheimer’s disease. It draws significantly on work carried out by Dr Thambisetti during his time as an Alzheimer’s Society fellow.’
‘We are not yet able to say that changes to the clusterin will lead to Alzheimer’s disease. However, researchers can now further investigate what the protein does and whether it is possible to alter the progression of Alzheimer’s by developing drugs to target it. One in three people over 65 will die with dementia. This week, Dementia Awareness Week, Alzheimer’s Society is asking people to Remember the Person behind the diagnosis.’

Notes
This week is Dementia Awareness Week. It runs until 10 July 2010. The theme of the biggest event in Alzheimer’s Society’s calendar is Remember the Person.
