This is PBA after dementia, what about after stroke? Whom is going to answer that question? ASA or NSA are you going to sponsor research to answer that f*ckingly simple question? Or are you going to continue to sit on your ass WAITING FOR SOMEONE ELSE TO SOLVE THE PROBLEM?
Dextromethorphan, Quinidine Effective
for Pseudobulbar Affect Secondary to Dementia
A fixed combination of dextromethorphan and quinidine has
demonstrated efficacy in treating pseudobulbar affect (PBA) and
depressive symptoms in patients with dementia, researchers reported here
at the 168th Annual Meeting of the American Psychiatric Association
(APA).
“The PRISM-2 is an open label study that enrolled patients with PBA
secondary to dementia, stroke, or traumatic brain injury,” explained
Andrew Cutler, MD, Florida Clinical Research Center, LLC, Sarasota,
Florida.
The analysis focused on patients form PRISM-2 who had PBA secondary
to dementia to determine if the medication had any impact on treating
any depression that patients experienced.
“The way that this medication works suggests that it will affect
mood,” said Dr. Cutler. “These were no patients who had significant
clinical depression, but they had depressive symptoms.”
PBA symptoms were significantly enhanced from study entry to the
12-week mark, with a 67.7% decrease in PBA episodes and a mean change of
-7.2 on the Center for Neurologic Study-Liability Scale (P< .001).
“By day 90, the PBA episodes were cut down to 3 a week,” said Dr.
Cutler, noting patients had multiple PBA episodes daily at study entry.
“There was tremendous improvement in episodes of PBA.”
The study also looked at depressive symptoms as measured by the
Patient Health Questionnaire-9. They found an improvement on that scale
that was statistically significant, with a change from 13.2 at study
entry to 7.4 after 12 weeks (P< .001).
Of note, there was not a direct relationship between improvement in PBA symptoms and reduction in depressive symptoms.
The most common adverse events were headache, urinary tract infection, and diarrhoea.
The study was limited by the fact that it was not randomised; rather it was an open-label design.
Funding for this study was provided by Avanir Pharmaceuticals, Inc.
