Many people worry that they will get Alzheimer’s when they get older. It is the most common form of dementia, which is considered incurable. The risk factors range from obesity and high blood pressure to smoking. As a new study by Danish researchers shows, a certain disease also increases the likelihood of developing dementia: Depression.

Study finds link between depression and dementia

The team found a “sustained association between dementia and depression diagnosed in early and middle age,” the study said. This published it in the journal “Jama”. The data of over one million Danes was examined for this purpose.

The results “suggest that depression may increase the risk of dementia” – and that by 2.41 times.

This was also the case when the depression was diagnosed in early adulthood. The association was stronger in men than in women.

Depression has been considered an early symptom of dementia. “The results therefore provide strong evidence that depression is not only an early symptom of dementia, but also that depression increases the risk of dementia,” London psychiatrist Natalie Marchant classified the study at “CNN”.

But how are the two diseases related? So far, the researchers have not been able to answer this with any certainty. However, there are three theories that Merchant mentions:

  1. For example, there are common risk factors for depression and dementia that appear earlier in life and could thus link the diseases.
  2. Depression may also increase the risk of dementia through changes in the levels of important neurotransmitters in the brain.
  3. Or, depression can lead to changes in health behavior, which in turn increase the risk of dementia.

To what extent the treatment of depression can reduce the risk of dementia again, the scientists want to investigate further.

This is how depression manifests itself

Depression is one of the most common and, in terms of its severity, one of the most underestimated illnesses, writes the German Depression Aid and Suicide Prevention Foundation. Every fifth to sixth adult suffers from it in the course of his life.

The portal “patient” lists the most important characteristics of depression

  • depressed, depressed mood
  • Loss of interest and joylessness as well
  • Lack of drive and fatigability.

It also mentions the “two-factor test”, which can provide initial indications of depression:

  1. In the past month, have you often felt down, sad, depressed, or hopeless?
  2. In the last month, have you had significantly less desire and pleasure in things that you usually enjoy doing?

If you answer “yes” to both questions, this could be the first sign of depression. In this case, be sure to consult a doctor.
