Posr Stroke Depression
A variety of emotional and behavioural disorders may develop following cerebrovascularlesions.
The DSM-IV categorizes post-stroke depression as a “mood disorder due to general medical conditions” with the specifiers of:
(a) depressive features;(b) major depressive-like episodes; (c) manic features; or (d) mixed features.
6Posr Stroke Depression
Five or more of the following present during two week period and representing a change in function, one symptom must be
either depressed mood or loss of interestDepressed mood most of the day for most days.Marked reduction in interest or pleasure in most
activities Significant weight loss or gain, significant
increase or decrease in appetite Insomnia or hypersomnia Psychomotor agitation or retardation Fatigue or loss of energy Feelings of worthlessness; inappropriate guiltReduced ability to think or concentrateRecurrent thoughts of death or suicide
7Posr Stroke Depression
The most associated with stroke are:
*
“depressed mood or loss of interest and at least 2 but fewer than 4 symptoms of major depression.”
8Posr Stroke Depression
Depression is often observed in patients with severe physical illnesses.
PSD has less emphasis on feelings of low self-esteem, guilt and self-blame, while hypochondrial concerns, lethargy and behaviour disturbances are most characteristic

12Posr Stroke Depression
Depression is a common complication post-stroke affecting approximately one-third of patients.
13Posr Stroke Depression
The mean prevalence of depression among in-patients in acute or rehabilitation settings was 19.3% and 18.5% for major and minor depression respectively while, among individuals in community settings, mean prevalence for majorand minor depression was reported to be 14.1% and 9.1%.
Among patients included in outpatient studies, mean reported prevalence was 23.3% for major depression and 15% for minor depression (Robinson 2003).
Overall mean prevalence ranged from 31.8% in the community studies to 35.5% in the acute and rehabilitation hospital studies

In community settings mean prevalence for major depression was 14.1% and 9.1% for minordepression .
Among patients included in outpatient studies, mean reported prevalence was 23.3% for major depression and 15% for minor depression (Robinson 2003).
Overall mean prevalence ranged from 31.8% in the community studies to 35.5% in the acute and rehabilitation hospital studies
15Posr Stroke Depression
Estimates of prevalence may be affected by the time from stroke onset until assessment.
Sub acute phase may be in a period of transition >>>>attempting to adjust.
In fact, the highest rates of incident depression have been reported in the first month following stroke.
16Posr Stroke Depression
While the incidence of major depression post-stroke may decrease over the first 24 months following stroke, minor depression tends to persist or increase over the same time period.

Approximately one-half of individuals identified as experiencing depression during the acute phase post stroke, continued to experience depression at 18 months; however, more women than men were identified in the acute phase while more men than women were identified as depressed at 18 months post stroke

19Posr Stroke Depression
There remains a wide diversity of findings in studies looking at the relationships between stroke location and depression.
Not all studies have confirmed this relationship and more recent meta-analyses have failed to establish a definitive relationship between the site of the brain lesion and depression
20Posr Stroke Depression
PSD most often with:- left cortical and basal ganglia lesions (the
closer to left frontal pole the more likely is severe, major depression),
right posterior pole (produces minor depression),
less so with subcortical lesions, and least with cerebellar brain stem lesions.
Apathy and paradoxical cheerfulness are associated with right anterior lesions.
21Posr Stroke Depression
Detection and diagnosis of post-stroke depression is often inconsistent.
Compliance with guidelines for screening is poor.
Identified barriers to routine screening include time pressures and concerns about
screening tools.

(0–100):
Pathological crying linked to infarct in basis of pontis and corticobulbarpathways and occurs in response to mood incongruent cues.
Emotionalism is crying that is congruent with mood (sadness) but patient is unable to control crying as they would have before stroke.
Catastrophic reaction is crying or withdrawal reaction triggered by a task made difficult or impossible by a neurologic deficit (e.g. moving a hemiplegic arm)

Stroke & Depression
27Posr Stroke Depression
Depression post stroke is associated with functional ability and may have a negative impact on recovery.
Although patients with post-stroke depression may experience significant recovery, functional ability will remain at a lower level than non-depressed patients, despite rehabilitation interventions.
Goodwin and Devanand (2008) demonstrated that co-occurrence of stroke and depression is associated with greater physical limitations than either condition on its own.
Physical impairment and post-stroke depression appear to act upon each other, and each influences the recovery of the other.
28Posr Stroke Depression
Early attention to issues of social withdrawal or impaired social functioning may help deter later depression and provide an opportunity for patients to resume pre-stroke activities.
Post-stroke depression impacts negatively upon social activity and vice versa.
29Posr Stroke Depression
Post-stroke depression appears to have a negative impact on cognition; however, the relationship between depression and cognitive impairment post stroke is poorly understood.
Posr Stroke Depression 30
The presence of mental health disorders post stroke, including depressive symptomatology, has been associated with an increased risk for mortality.
Further study to clarify the association between psychological distress and mortality is required.
Posr Stroke Depression 31
There is strong (Level 1a) evidence that early initiation of antidepressant therapy, in non-depressed stroke patients is associated with reduced risk for the development of post-stroke depression.
While treatment over a period of one year was associated with significant reduction in risk, further study is required to assess both duration of treatment and optimal timing for the initiation of therapy.
Early initiation of antidepressant therapy in non-depressed individuals is effective in preventing post-stroke depression.
Posr Stroke Depression 32
There is strong (Level 1a) evidence that ongoing individualized contact and support provided via various care provision models is associated with less deterioration of mood and/or mental health state following stroke.
Ongoing, individualized contact and support may reduce the risk for deterioration of psychological health following stroke.
Posr Stroke Depression 33
There is strong (Level 1a) evidence that heterocyclic antidepressants improve depression post stroke. Side effects in elderly patients mean that these medications should be used with caution in that population.
SSRI antidepressants are effective in the treatment of post-stroke depression.
There is moderate (Level 1b) evidence that reboxetine, a noradrenaline reuptake inhibitor, is effective in reducing retarded post-stroke depression.
There is limited (Level 2) evidence suggesting that venlafaxine, an SNRI, is a safe and effective treatment for post- stroke depression. Randomized controlled trials are required.
There is moderate (Level 1b) evidence that methylphenidate is more effective than placebo in improving depression and improving functional recovery. Methylphenidate (a psychostimulant) appears to be effective in treating depression post-stroke and has an earlier onset of action than traditional antidepressants
The herbal medicine Free and Easy Wanderer Plus may be effective in the treatment of PSD. Further research is required.
Posr Stroke Depression 34
Active care management in conjunction with antidepressant therapy may improve response to treatment.
Pharmacologic treatment of post-stroke depression is associated with improved functional recovery.
Treatment with antidepressants following stroke improves long-term survival.
Posr Stroke Depression 35
Electroconvulsive therapy may be a safe and effective treatment for post-stroke depression.
Repetitive transcranial magnetic stimulation is an effective and well-tolerated treatment for post-stroke depression in patients for whom pharmacotherapy is ineffective
