Depression may increase the risk of developing Alzheimer's: The Daily Telegraph reports on a study that followed more than 900 Catholic clergy for up to 13 years. It reports on a study that followed more than 900 Catholic clergy for up to 13 years. The study found that those who developed the disease had more symptoms of depression at the beginning of the study.
The main aim of the research was to look at changes in depressive symptoms in the early stages of Alzheimer's. There is a known association between dementia and depression. However, there are different theories as to whether depression causes Alzheimer's or whether they both develop because of a separate cause. By investigating changes in the severity of depression around the time that dementia develops, the researchers hoped to shed some light on the debate.
Their study found no increase in depressive symptoms before Alzheimer's became evident. This suggests that depression is not an early sign of the same processes that cause dementia. The researchers say that this therefore implies that depressive symptoms are a risk factor for Alzheimer's.
This study challenges the theory that depression and dementia are caused by another factor. It therefore adds weight to, but does not prove, the theory that depression is a risk factor for dementia. However, this study has shortcomings, and further research that is free of these should provide a clearer picture. Until more is known, depression sufferers should not be overly worried that they will develop dementia.
