Stroke Effects Print By Heidi Moawad, MD | Reviewed by a board-certified physician Updated September 29, 2016 If you have had a stroke, the effects of your stroke may endure long after your first stroke symptoms stabilize and after you receive appropriate stroke treatment.Your long-term stroke effects are, in many ways, similar to your initial stroke symptoms. What the immediate and long-standing effects of a stroke have in common is that they generally involve the same part of the body or the same cognitive function. For example, your arm may be weak, your face may be lopsided, speech might be garbled, or vision may be blurry. This is because the initial symptoms of a stroke correspond to the area of the brain that is injured by the stroke, as do the enduring residual effects.However, some effects of stroke can take months, or even years, to develop. The most common effects of a stroke are described below.Take a look at the regions of the brain that may be impacted by a stroke. Article How a Stroke Changes Your Personality Article How to Treat Your Post-Stroke Pain WeaknessMost of the time, weakness caused by a stroke affects one side of the body. Weakness of one side of the body is called hemiparesis, while complete paralysis of one side of the body is called hemiplegia.The hemiparesis or hemiplegia after a stroke can affect the face, arm, or leg or a combination of the three. Generally, a stroke survivor suffers long-term weakness that is less severe than the initial weakness that he or she experienced while the stroke was in its early stages, especially if stroke treatment was initiated promptly.Hemiparesis and hemiplegia result from a stroke that damages one side of the brain in one or more of the regions that control motor function. A cortical stroke, a subcortical stroke, or a brainstem stroke can cause hemiplegia or hemiparesis.Balance Problems or DizzinessThe majority of stroke survivors continue to feel a bit off balance, even during and after stroke recovery. These sensations can manifest in many different ways, and they can come and go, but dizziness typically stabilizes about six months after a stroke and does not normally continue to worsen in severity.Some stroke survivors truly are off balance, some feel dizzy, some experience light-headedness and some have a sensation that the room is spinning.A stroke in any region of the brain can cause a sense of feeling off balance, but a stroke involving the brainstem or the cerebellum is more likely to result in persistent dizziness and trouble maintaining balance and coordination.Physical therapy is the most effective way to combat balance impairment after a stroke, and there are a number of safe at-home balance exercises that you can do on your own to maximize your sense of balance and reduce your dizziness. Article Why Does a Stroke Cause the Loss of Peripheral Vision? Article How Can a Stroke Can Change Your Sense of Humor? Vision ChangesThere are a variety of vision changes that may result from a stroke, including double vision (diplopia) visual field loss (hemianopsia), jerking of the eyes (nystagmus), and loss of vision. These are the most common visual changes after a stroke, although some stroke survivors lose vision in the center of the visual field, while other stroke survivors lose the ability to see color.Disruptions in vision after a stroke can be a serious handicap, interfering with driving and even with safety at home.Speech and Communication ProblemsAphasia Aphasia describes trouble speaking or understanding words due to a disease or an injury of the brain. When a stroke involves the dominant side of the cerebral cortex (usually the left side) a stroke survivor may have trouble forming words (Broca's aphasia) or trouble understanding words and language (Wernicke's aphasia.) Usually, a stroke survivor has either Broca's aphasia or Wernicke's aphasia, and only rarely experiences both types of aphasia, for instance, if the stroke is very large. Dysarthria Dysarthria is a problem in which a stroke survivor cannot speak clearly due to weakness and diminished coordination of face and mouth muscles after a stroke.Stroke survivors who have dysarthria do not necessarily have aphasia, as these are two completely different types of speech problems. Most stroke survivors who have dysarthria can understand speech and can use the correct words, but they have trouble making their words understandable due to the muscle weakness or muscle coordination problems.Cognitive DeficitsCognitive changes after a stroke include memory glitches, trouble solving problems, and difficulty understanding concepts.The severity of cognitive changes after a stroke varies tremendously from one stroke survivor to another. In general, a larger stroke results in more severe cognitive deficits than a smaller stroke.Another factor that influences the degree of cognitive deficit after a stroke is whether a stroke survivor had any cognitive problems prior to the stroke. Article Weber's Syndrome Symptoms and Diagnosis Article How a Stroke Changes Vision A person who had early dementia or was cognitively impaired for any reason prior to a stroke is at a higher risk of suffering from a worse cognitive deficit after a stroke.Some stroke survivors experience severe dementia-like symptoms after a stroke, but that is typically the consequence of the buildup of damage from several strokes, rather than only one stroke.Spatial Difficulties/Neglecting One Side of the BodyThe neglect of one side of the environment and the diminished ability to notice one side of the body is called hemispatial neglect. This results from a stroke of the right cerebral cortex.Hemispatial neglect causes a stroke survivor to have trouble interacting with one side of the environment and sometimes even recognizing one side of his or her own body. Often, stroke survivors who have hemispatial neglect are completely unaware that they had a stroke.Behavioral ChangesAfter a stroke, new behaviors can include a lack of inhibition, which means that people may behave inappropriately or childlike after a stroke. Other changes in behavior include a lack of empathy, loss of sense of humor, irrational jealousy, and anger.Emotional DistressMany people experience sadness and depression after a stroke. This is a result of the physical changes in the brain that accompany a stroke.But there are other emotional changes that arise in response to the new circumstances that a stroke survivor must face, such as sadness and angst regarding the handicaps that result from a stroke. While depression is the most common mood after a stroke, some stroke survivors also experience anxiety, anger, or frustration.PainAs many as 60 to 70 percent of stroke survivors experience new onset pain after a stroke. Post stroke pain can include muscle pain, facial pain, headaches, low back pain, and neck pain. The treatment for post stroke pain includes rest, physical therapy, and medication. Post stroke headaches require special attention from your doctor, but they can improve with the right treatment.Fatigue and Sleeping ProblemsMost stroke survivors experience some degree of fatigue. This can manifest as excess sleeping or as tiredness with inability to get enough rest.On a related note, sleep disturbances such as waking in the middle of the night, having trouble falling asleep, trouble staying asleep, and sleeping sporadically throughout the day are very common after a stroke. These problems typically add to the overall fatigue after a stroke.Unlike many other post stroke effects, sleep disturbances do not have a tendency to improve on their own. If you experience sleep problems after a stroke, you should discuss your symptoms with your doctor.Swallowing DifficultiesAbout half of stroke survivors experience some problems with chewing and swallowing food.A speech and swallow evaluation can identify swallowing problems after a stroke. While it might not seem to be a major issue, swallowing problems are, in fact, quite dangerous. The choking that results from stroke-induced muscle weakness may cause serious illness, such as aspiration pneumonia or even life-threatening breathing obstruction problems.Trouble With UrinationAfter a stroke, many stroke survivors experience incontinence, which is urinating when you do not want to. Some stroke survivors also experience bladder retention, which is the inability to urinate when you want to. Both of these problems are inconvenient and embarrassing, but they can be managed with medical treatment.Muscle AtrophyAfter a stroke, the weakened muscles may be so weak that you cannot use them at all. When muscles are unused for a prolonged time, they can literally shrink, becoming smaller, losing actual muscle bulk and tone. Unfortunately, muscle atrophy results in worsening muscle weakness.It is difficult to recover from muscle atrophy, but rehabilitation techniques can help improve the situation and slowly rebuild muscle. It is better to prevent muscle atrophy through pre-emptive post stroke rehabilitation methods that engage weakened muscles before they shrink.Muscle SpasticitySometimes weakened muscles become stiff and rigid after a stroke, possibly even jerking on their own. Muscle spasticity is often painful, with pain centered around the spastic muscles and involving nearby muscles as well. Muscle spasticity and rigidity result in diminished motor control of the already weakened muscles.Muscle spasticity can be prevented with active post stroke rehabilitation. If muscle spasticity develops after a stroke, there are a number of effective medical treatments that can be used to control the symptoms, but the medications do not completely reverse spasticity.SeizuresAfter a cortical stroke, as many as 30 to 50 percent of stroke survivors experience seizures. This is because when the cerebral cortex becomes injured after a cortical stroke, this region of the brain may start to produce erratic electrical activity, resulting in a seizure.Sometimes, seizure prevention is a part of the post stroke care program if there is a high risk of post-stroke seizures. Some stroke survivors develop seizures years after a cortical stroke in the context of a serious medical event, such as surgery or a major infection. Post-stroke seizures can be managed with medication.A Word From VerywellThe effects of a stroke are wide ranging. It is important to recognize that, while some stroke effects such as hemiplegia and vision loss are expected, other stroke effects such as pain, dizziness, and trouble urinating also deserve your attention to help you live your best life possible as you recover from your stroke.
