Ischemic Stroke precedes depression.
One in two survivors of stroke will get depression. One in four survivors will get anxiety. Depression and anxiety can happen at any time after a stroke.
Pseudobulbar Affect, also called “emotional lability,” “reflex crying” or “labile mood,” can cause: Rapid mood changes — a person may “spill over into tears” for no obvious reason and then quickly stop crying or start laughing.
Depression was more frequent in patients with stroke in the left hemisphere (63%). We can conclude that depression after stroke is more frequent in younger patients, female patients, patients with localized stroke in the left hemisphere and with higher NIHSS disability score.
Mental illnesses that are commonly associated with stroke are depression [38], anxiety [39], fatigue [40], sleep disturbances [41], and emotionalism [42].
Depression is a common experience for stroke survivors. It's often caused by biochemical changes in the brain. When the brain is injured, the survivor may not be able to feel positive emotions. Depression can also be a normal psychological reaction to the losses from stroke.
Treatment for post-stroke depression may include psychotherapy as an adjunct in combination with antidepressants [Evidence Level A], as appropriate to the person who has experienced a stroke's health state and other deficits (e.g., communication and other cognitive deficits).
The pathology underlying PSD and major depression differs. Stroke leads to neuronal and glial cell death due to hypoxic lesion, whereas major depression is not always associated with detectable cell death.
Depression is common after stroke, affecting approximately one third of stroke survivors at any one time after stroke (compared with 5%–13% of adults without stroke), with a cumulative incidence of 55%.
Both the frontal lobe and the limbic system play large roles in emotions. When a stroke damages the emotion center of the brain, it can result in a condition known as pseudobulbar affect, which causes uncontrollable emotional outbursts. Pseudobulbar affect is also common following a brainstem stroke.
Another personality change that occurs after stroke is impulsiveness. This is characterized as the inability to think ahead or understand consequences. Impulsiveness is more commonly seen in people with right-side or a frontal lobe stroke.
As you begin to recover, you might feel that your behaviour changes or improves. You may start feeling better physically and emotionally. But some changes will be long term. You are still the same person, but a stroke may change the way you respond to things.
How Does a Stroke Impact Life Expectancy? Despite the likelihood of making a full recovery, life expectancy after stroke incidents can decrease. Unfortunately, researchers have observed a wide range of life expectancy changes in stroke patients, but the average reduction in lifespan is nine and a half years.
“Stroke survivors experience feelings of anger, frustration, anxiety, sadness, fear and hopelessness. These emotions are common with post-stroke depression, which affects more than one-third of stroke survivors,” says Dr. Ashish Masih, a neurologist at INTEGRIS.
Stroke lesions in the posterior lobe of the left cerebellar hemisphere and the left cerebellar peduncle were significantly correlated with severity of depression. According to the interpretation of the authors, these findings add to the understanding of the role of the cerebellum in emotional processing.
Patients with stroke experience cognitive decline that is faster than that of stroke-free controls from 1 to 3 years after onset. An increased rate of decline is associated with older age and recurrent stroke.
Changes in your emotions and to your personality are common after stroke. It's very normal to experience strong emotions after stroke, however these emotional reactions usually get better with time. Longer-term emotional and personality changes can be very challenging.
Subcortical ischemic depression refers to vascular depression specifically due to lesions and restricted blood flow, known as ischemia, in certain parts of the brain. However, the disorder is typically described as vascular depression in the literature.
In this study, people with symptoms of depression had a 46% increased stroke risk compared with those without such symptoms.
Right hemisphere stroke produces an increase in serotonin receptor binding, which is not found following comparable left hemisphere strokes. Within the left hemisphere, the lower the serotonin binding, the more severe the depression.
No two strokes are the same. Some people may feel more like themselves within just a few days, without any lasting physical or cognitive issues. But for others, it may take several months to heal or adjust to any long-term effects.
The development of depressive symptoms is the most frequent affective complication after a stroke. Post-stroke depression (PSD) has been widely studied and has been estimated to affect between 29% and 33% of patients1,2.
Our study showed that SSRIs are effective in preventing and treating depression, and improving anxiety, motor function, cognitive function, and dependence in patients after stroke.
Apathy is a reduction in goal-directed activity in the cognitive, behavioral, emotional, or social domains of a patient's life and occurs in one out of three patients after stroke.
