of causes Impact of fatigue post strokeMeaning of Fatigue to patients What can help Professionals role in supporting patients with
post stroke fatigue Overview
What is itA feeling of lack of energy and weariness and an aversion of
effort.
Mead et al (2007)
It may not be caused by activity It may not improve with rest
How common is itReports vary Estimated prevalence rates between 16-70 %
even in stroke patients who seem to recover well. (Glader 2002, Carllson 2003; Leegard 1983)
Can go on for years without improvement (Naess et al 2005, Christensen et al 2008, Schepers et al 2006, van der Werf 2001)
Prevalence rates on the chronic phase that show no natural improvement are as high as 38-73% (Lerdal et al 2009)
A Cochrane review found Some association with depression (Naess 2005; Schepers 2006; van der
Werf 2001), One small study found a relationship with brain stem lesions (Staub
2001), Others did not (Ingles 1999; Morley 2005; Naess 2005).
Possible underlying biological mechanism; one small study of 38 participants found a relationship with plasma
glutamate/glutamine ratio (Syed 2007). In cancer patients, fatigue may be related to cortisol dysregulation
(Bower 2005). The relationship between cortisol dysregulation and fatigue after stroke has
not been studied. Another interesting hypothesis is that fatigue may be associated with
physical deconditioning, which is common after stroke (Saunders 2004), but the single study which has investigated the relationship between
fatigue and fitness found no association (Michael 2006).
Put simply Number of factors involved in having a greater risk of stroke
Type of stroke Size of stroke Location of stroke Number of strokes
Other factors associated with fatigue Depression Anxiety Reduced functional health Disrupted Sleep Pain Reduced physical fitness
(Lerdal et al 2009, Naess et al 2005, Tang, et al 2009, Snaphaan, et al 2011)
Put simply The Cause of fatigue after stroke is still
unclearDiagnosis is typically based on exclusion of
other conditions, There are often frequent comorbiditiesNo known neuropathological basisNo established single cause or pathogenesis No recognised treatment
How bad is itOutcome tools

DependenceMRS
What do the National Guidelines say?There is no evidence that
medication improves outcomes in fatigue (McGeough et al 2009).
6.37.1 RecommendationsA Fatigue in medically stable
patients should be assessed particularly where engagement with rehabilitation, or quality of life is affected.
B Patients with fatigue and their families should be given information and reassurance that the symptom is likely to improve with time.
What do patients sayLots of patients said it started at the time of
their stroke. Different factors were reported to improve
fatigue,exercise, good sleeprehabilitation and rest. Fatigue influences patients’ sense of “control”
after their stroke Small mixed study Barbour & Mead (2012)
Cognitive and Graded Activity Training Can AlleviatePersistent Fatigue After Stroke
A Randomized, Controlled Trial Aglaia et al (2013)
This randomized, controlled, assessor-blind clinical trial was conducted in 8 rehabilitation centers.
83 stroke patients randomly assigned (4 months after stroke) to 12 weeks of Cognitive Therapy (CO) or CO with Graded Activity Training (GRAT) after
qualification.73 patients completed treatment and 68 were
available at follow-up.
Results Both treatment showed benefits on fatigue
but not on pain or anxietyCOGRAT group better than Co group on
physical endurance Conclusions
A 12-week cognitive therapy program can alleviate persistent fatigue after stroke. The
best results are obtained when cognitive therapy is augmented with graded activity
training. Aglaia et al (2013)
Summary Fatigue after stroke is common and can cause a high
impact on the function and quality of life into the long-term.
Causes are still unclearNo specific medication to treat itCognitive therapy and Graded Activity Training program
may helpPatient report benefits from
Activity and rest Keeping occupiedNot overdoing it A good sleep pattern Modify medication regimes
