Maybe I missed it in the article, but there was nothing about corellation vs causality?

When you are depressed, you will often experience both tiredness and cognitive issues anyway. Which results in longer sleep times due to massive exhaustion from being always on your limit. So maybe they sleep longer because of the cognitive issues?

Here's a brief review of the study results. They were only looking for association, not causality:

Long sleep was associated with reduced overall cognitive function (β ± standard error = −0.25 ± 0.07, p < 0.001), with strongest effects in those with depressive symptoms using (−0.74 ± 0.30, p = 0.017) and not using antidepressants (−0.60 ± 0.26, p = 0.024). Weaker but significant effects were observed in those without depressive symptoms (−0.18 ± 0.09, p = 0.044). No significant associations were observed in participants using antidepressants without depressive symptoms.

**Weaker but significant effects were observed in those without depressive symptoms (−0.18 ± 0.09, p = 0.044). **

This is certainly something to investigate further.
