Does fluoxetine reduce apathetic and depressive symptoms after stroke? An analysis of the Efficacy oF Fluoxetine—a randomized Controlled Trial in Stroke trial data set

If our stroke medical 'professionals' would actually rub their two functioning neurons together the spark generated just might lead to the realization that depression treatment is totally unnecessary once 100% recovery protocols are available.  Solve the primary problem of 100% recovery and you don't have to work on the secondary problem of depression. Do you blithering idiots ever think at all?

 

Does fluoxetine reduce apathetic and depressive symptoms after stroke? An analysis of the Efficacy oF Fluoxetine—a randomized Controlled Trial in Stroke trial data set

Abstract

Objective:

Apathy is a common and disabling symptom after stroke with no proven treatments. Selective serotonin reuptake inhibitors are widely used to treat depressive symptoms post-stroke but whether they reduce apathetic symptoms is unknown. We determined the effect of fluoxetine on post-stroke apathy in a post hoc analysis of the EFFECTS (Efficacy oF Fluoxetine—a randomized Controlled Trial in Stroke) trial.

Methods:

EFFECTS enrolled patients ⩾18 years between 2 and 15 days after stroke onset. Participants were randomly assigned to receive oral fluoxetine 20 mg once daily or matching placebo for 6 months. The Montgomery–Åsberg Depression Rating Scale (MADRS) was administered at baseline and 6 months. Individual items on this scale were divided into those reflecting symptoms of apathy and depression. Symptoms were compared between fluoxetine and placebo groups.

Results:

Of 1500 participants enrolled, complete MADRS data were available for 1369. The modified intention-to-treat population included 681 patients in the fluoxetine group and 688 in the placebo group. Confirmatory factor analysis revealed that apathetic, depressive, and anhedonic symptoms were dissociable. Apathy scores increased in both fluoxetine and placebo groups (both p ⩽ 0.00001). In contrast, fluoxetine was associated with a reduction in depressive scores (p = 0.002)

Conclusion:

Post-stroke apathetic and depressive symptoms respond differently to fluoxetine treatment. Our analysis suggests fluoxetine is ineffective in preventing post-stroke apathy.

Introduction

Apathy occurs in one out of three patients after stroke.1 It describes a reduction in goal-directed activity in the cognitive, behavioral, emotional, or social domains of a patient’s life. Despite its frequency, apathy is clinically under-recognized, and there are no proven drug treatment approaches.
Antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), are often used to treat post-stroke depression. Whether SSRIs are also effective in apathy remains uncertain.1 Despite shared symptoms, post-stroke apathy and depression are dissociable syndromes. Negative emotionality is a key characteristic of depression that distinguishes it from apathy. Depressed patients may present with pessimism and hopelessness, while those with apathy show lack of emotional distress. Recent studies suggest apathy and depression have different neuroanatomical correlates with white matter track damage and subsequent complex network disruption underlying apathy, but not depression.1,2 This suggests they might respond differently to therapeutic interventions.
We determined whether fluoxetine reduced apathy in a post hoc analysis of data from the Efficacy oF Fluoxetine, a randomized Controlled Trial in Stroke (EFFECTS) trial.
