Depression, age, medical problems linked to dependence after stroke

A study has indicated that people who have stroke are more likely to be dependent if they are depressed, older or have other medical problems.

"Post-stroke depression is a common problem. About 795,000 people in the United States have a stroke each year and one third of survivors develop depression as a result," said study author Arlene Schmid, with the Richard L Roudebush Veterans Affairs Medical Centre and Indiana University in Indianapolis.

"We wanted to see whether depression and other factors affected function and dependence after a stroke."

For the study, researchers gathered information about 367 ischemic stroke survivors with an average age of 62 with no severe language or thinking skill impairments. Of those, 174 were diagnosed with post-stroke depression one month after the stroke.

The participant's level of independence was rated using a zero to five scale, with five being the most severely disabled and dependent. Three months later, 20% of participants were considered dependent, scoring a level three or higher.

The study found that stroke survivors with depression were more likely to be dependent if they were older, had other coinciding health problems or were severely depressed compared to those who were younger (64 vs 59), free of other health problems (18 vs 15 points on a test for co-morbidities) or not depressed (16 vs 14 points on a patient health questionnaire).
