Depression an early warning sign for Alzheimer's

DEPRESSION appears to flag later cognitive decline, raising the possibility of early interventions with anti-depressants, a Western Australian study shows.

The study of 460 healthy adults shows those with signs of depression are more likely to have memory problems from middle-age onwards.

Lead author Dr Hamid Sohrabi, from Edith Cowan University, says the study lays the groundwork for a new screening test for cognitive decline caused by psychiatric comorbidities such as depression.

“We found that the signs of depression begin well before the symptoms of dementia begin manifesting,” he says.
