Testing an Intervention to Improve Post-hospital Outcomes in Persons Living with Dementia and Their Family Care Partners
Background and Objective Hospitalized persons living with dementia are at risk for functional decline, behavioral symptoms of distress, and delirium, all persisting in the post-acute period. In turn, family care partners (FCPs) experience increased anxiety and lack of preparedness for caregiving, compounding existing strain and burden. Family-centered Function-focused Care (Fam-FFC) purposefully engages FCPs in assessment, […]

Low physical activity is associated with two hypokinetic motor abnormalities in psychosis
Individuals with schizophrenia engage in more sedentary behavior than healthy controls, which is thought to contribute to multiple health adversities. Age, medication side effects and environment are critical determinants of physical activity in psychosis. While motor abnormalities are frequently observed in psychosis, their association with low physical activity has received little interest. Here, we aimed […]

A phase 2a randomised, double-blind, placebo-controlled, parallel-group, add-on clinical trial of ebselen (SPI-1005) as a novel treatment for mania or hypomania
Rationale Lithium is an effective prophylactic and anti-manic treatment in bipolar disorder; however, its use is declining through perceived poor tolerance and toxicity. Lithium inhibits inositol monophosphatase (IMPase), a probable key therapeutic mechanism. The anti-inflammatory drug, ebselen, also inhibits IMPase and appears well-tolerated and safe.
