Study to Assess the Risk Factors of Depressive Symptoms in Elderly

A ninety year old lady is covered in an insulating blanket to try and stay warm and is unable to leave her house unaided as she is registered blind and frail.A new study from the Max Planch Institute for Human Cognitive and Brain Sciences and the University of Münster finds that depression caused by cardiovascular diseases plays a smaller role in seniors compared to younger people. It was previously unknown whether age influenced the likelihood of suffering from depressive mood or depression.

Smoking has previously been shown to be a higher risk factor for high blood pressure, obesity, heart disease, and diabetes. But this new study shows that the risk of being affected by depressive mood or depression also increases. The more risk factors the smoker has, the higher the chance of depression.


Until now, it was unclear how age played a role in this risk factor for depression. Previous studies have already shown that other diseases such as dementia or stroke need a combination of several risk factors to lead to a more frequent onset of disease between the age of 40 and 65 compared to old age. Until now, it was unclear if this also applies to depression.

Longitudinal Study

Researchers investigated the relationships between risk factors and depression with the help of the longitudinal study, “English Longitudinal Study of Aging,” in which more than 18,000 people in Great Britain participated over a period of 12 years. Data were analyzed for more than 7,000 people over the age of 50 who had not yet suffered a heart attack, stroke, or dementia. High blood pressure, diabetes, smoking, obesity, and high cholesterol were all considered risk factors.

Every two years, the extent of depressive mood was recorded along with the calculation of depressive symptoms as a function of risk factors and age. Growth models were used to help calculate the development of individuals over the years. This resulted in a curve for each person, whose different courses could be explained by adding or removing risk factors. The influence of gender and education was removed accordingly.

The first author of the study, Maria Blöchl explains, “The risk factors lead to changes in the brain structure. If regions responsible for emotion regulation change in the process, the mood of those affected probably deteriorates and this can eventually lead to depression.”


Her team believes that there is likely a psychological component, and these factors usually lead to physical and psychological stress, which in turn can lead to a depressive mood. Blöchl adds, “The general health status is then often not very good and people take more medication. This is often psychologically stressful.”

Previous research has shown that older people are better able to cope with stress. They may also be better at coping with existing ailments which can lead to a different way of dealing with symptoms of illness and prevent depressive moods. Further research is needed to investigate the relationship between depression and coping methods in seniors.

After going through health problems and becoming frustrated with the conventional ways doctors wanted to treat her illness (which were not working), she took it upon herself to find alternative treatments. This led her to revolutionize her own diet to help her get healthier and tackle her health problems. She began treating her illness by living a more balanced lifestyle through healthy food choices, exercise and other alternative medicine such as meditation. This total positive lifestyle change led her to earn a diploma in Nutritional Therapy from Health Sciences Academy in London, England. Today, Sarah enjoys helping others by teaching healthy lifestyle changes through her personal consultations and with her regular contributions to the Doctors Health Press. Also, passionate about following her dreams in life, Sarah moved to France and lived in Paris for over 5 years where she earned a certification in beadwork and embroidery from Lesage (an atelier owned by Chanel). She then went on to be a familiar face sitting front row and reporting from Paris Fashion Week. Sarah continues to practice some of the cultural ways of life she learned while in Europe.
