Study examines how depression symptoms shape heart disease and cognitive aging
Researchers followed 5,423 adults aged 50 and older in England over 14 years to study heart disease, depressive symptoms and changes in memory and thinking.
They grouped people by whether their depressive symptoms stayed low, moderate or high over time; these patterns were not diagnoses of depression.
The link between heart disease and cognitive decline varied across those symptom patterns, though the available findings do not say how each group differed.
At the study’s start, people with cardiovascular disease performed less well on tests of memory, orientation and word fluency than people without it.
Heart disease and depressive symptoms have each been linked to poorer cognitive health, making their combined relationship important as dementia cases are projected to rise worldwide.
Because symptom and cognitive changes were assessed over overlapping periods, the study could not establish which changes came first.
A 14-year study of 5,423 adults examined whether long-term depressive symptom patterns change the association between cardiovascular disease and cognitive decline.
The analysis used data from the English Longitudinal Study of Ageing, collected from 2004–2005 to 2018–2019.
At baseline, 1,080 participants, or 19.9%, had cardiovascular disease, and they performed more poorly on memory, orientation and semantic fluency tests than participants without the condition.
Researchers grouped participants into low-stable, moderate-stable and high-stable depressive symptom trajectories.
Because depressive symptoms and cognitive changes were assessed over overlapping periods, the study could not establish whether persistent symptoms preceded cognitive decline.
- Who
- Researchers analyzed data from 5,423 middle-aged and older adults in England.
- What

- England, using data from the English Longitudinal Study of Ageing.
- Why
- Researchers investigated whether patterns of depressive symptoms over time affect the relationship between cardiovascular disease and cognitive decline.
This story does not have two clearly opposing sides.
Data collection began with wave 2 of the English Longitudinal Study of Ageing.
Data collection ended with wave 9.
