Drawing test strong predictor for post-stroke mortality

Researchers analysed data from a study of 1000 Swedish men whose intellectual capacity was assessed at age 70. Some 155 of the men had a stroke and 84 subsequently died.

They found that the men’s pre-stroke scores on the Trail Making Test, which involves drawing lines between numbers in ascending order as quickly as possible, was significantly related to the likelihood of post-stroke mortality. Mini Mental State Exam scores were unrelated to mortality.
