Scientists say that depression symptoms that continue to progress into old age can be a warning sign of dementia.
The study found out that symptoms like chronic depression seemed not to be associated with it.
The Dutch researcher’s interest was the progression of depression in older adults and the risk that is associated with it.
The conclusion of the study was that depression can act as a signal that the condition is worsening.
These results were published in The Lancet Psychiatry after conducting tests on 3,000 adults of age 55 years and above living in Netherlands.
All the participants had depression but did not have dementia when the study started.
The Erasmus University Medical Center Dr. M Arfan said that symptoms of depression that increase as time passes can be an indicator of dementia in later life.
“There are a number of potential explanations, including that depression and dementia may both be symptoms of a common underlying cause, or that increasing depressive symptoms are on the starting end of a dementia continuum in older adults,” he said.
How to prevent
It is still unknown the effect that depression has on dementia.
But what is known is that they usually come hand in hand.
Dr. Simone from Centre for Healthy Brain Ageing said that research ought to be carried in deeper details so as to expose the link between the two.
“A focus on lifestyle factors such as physical activity and social networks, and biological risk factors such as vascular disease, neuroinflammation, high concentrations of stress hormones, and neuropathological changes, might bring new treatment and prevention strategies a step closer,” she wrote in a linked editorial in the journal.
Each person has different levels of depression. Some have a brief depression while others can experience it for months if not years.
It is important to maintain low depression levels that can not affect the risk of dementia.
