Some Stroke Survivors Can't Recognize Fear, Anger in
THURSDAY, Feb. 2 (HealthDay News) -- Damage in some areas of the
forebrain may prevent some stroke survivors from being able to
recognize anger, disgust and fear, emotions that are related to
assessing threats, a small study indicates.
It included 23 young patients who'd survived a stroke that
impacted their basal ganglia, an area of the forebrain, and 68
Stroke survivors with damage in the basal ganglia had a reduced
ability to recognize threat-related facial expressions in others,
suggesting that the basal ganglia plays a role in threat
Researchers also did MRIs on the patients and tested a wide
range of the participants' thinking and motor abilities and social
behaviors, and screened them for coexisting conditions such as
depression and anxiety.
Physicians should determine how well stroke survivors with basal
ganglia damage are able to identify emotions in others and if
necessary, assistance with that should be part of their
rehabilitation program, the researchers said.
The study was to be presented Thursday at the American Stroke
Association meeting in New Orleans.
Because this study was presented at a medical meeting, the data
and conclusions should be viewed as preliminary until published in
a peer-reviewed journal.
