Why is a trial of antidepressant treatment, followed by reassessment of cognition, often both a diagnostically useful step and an appropriate clinical intervention in a suspected case?

Because depressive pseudodementia's cognitive impairment characteristically improves substantially, sometimes dramatically, once the underlying depression is treated, which a genuine dementia would not do

Because antidepressants directly reverse the neurodegenerative changes seen in true dementia

Because it avoids the need for any further cognitive assessment altogether

Because cognitive symptoms are not considered real until treatment is tried
