Psychological symptoms and personality characteristics affect quality of life following stroke
Anxiety, depression and fatigue may decrease long-term
quality of life (QOL) for subarachnoid hemorrhage (SAH) stroke survivors, researchers
reported in Stroke: Journal of the American Heart Association.
In a study assessing 141 men and women living in the
community two to four years after a SAH stroke, researchers found health-related
QOL was related to psychological symptoms, such as mood disorders, fatigue, cognitive
complaints, and to personality characteristics.
Depression, anxiety and fatigue were pronounced in a
significant proportion of SAH survivors studied, with a strong association to
decreased QOL.
Researchers found 32 percent of the survivors reported
anxiety; 23 percent reported depression; and 67 percent reported fatigue.
The patients - discharged from the University Medical
Center, Utrecht, in The Netherlands to their own homes - were an average 51 years.
Sixty-six percent were women.
"The major point is to look beyond physical symptoms
and look at psychological symptoms and personality characteristics to evaluate
quality of life," said Anne Visser-Meily, M.D., Ph.D., lead author of the study
and rehabilitation specialist at the Rudolph Magnus Institute of Neuroscience
at University Medical Center in Utrecht. "These characteristics are important
in planning rehabilitation and targeting an intervention to help improve quality
of life."
Researchers evaluated QOL scores using the well-established
Stroke Specific Quality of Life scale. The scale has 49 items, merged into four
domains reflecting physical, cognitive, emotional and social QOL. They also used
other scales to help in evaluation.
Researchers found the best scores in the physical domain;
the worse were in the emotional and social domains. All psychological symptoms
and personality characteristics were strongly related to the total QOL score.
The study examined such personality characteristics as
passive coping and neuroticism. "When you analyze depression, anxiety and fatigue,
you find there is a strong correlation with a passive coping style and neuroticism,"
Visser-Meily said. "Those with a passive coping style need psychological support
to encourage them to be more independent."
Cognitive function is another important determinant of
QOL associated with coping style. Those who had a passive coping style and who
were depressed reported more neuropsychological problems. "This emphasizes the
need to take personality into account as a potential vulnerability factor for
decreased QOL," said Visser-Meily.
