Both large strokes and multiple small strokes can cause vascular dementia. Conditions such as old age, prior memory problems, a history of several strokes, or a stroke located in the left side of the brain all seem to increase the likelihood of dementia in the first year after stroke.
Conclusions. Left-hemispheric ischemic strokes appear to be more frequent and often have a worse outcome than their right-hemispheric counterparts. The incidence of large-vessel ischemic strokes is higher in the left middle cerebral artery distribution, contributing to these hemispheric differences.
Effects of a left hemisphere stroke in the cerebrum
Right-sided weakness or paralysis and sensory impairment. Problems with speech and understanding language (aphasia) Visual problems, including the inability to see the right visual field of each eye. Impaired ability to do math or to organize, reason, and analyze ...
Left-sided strokes might be referred more frequently because they lead to clear symptoms, such as aphasia, whereas right-sided strokes may lead to less explicit symptoms, such as hemineglect or spatial disorientation.
A stroke can have many different effects, depending on which side of the brain is affected. A right-sided stroke can cause left-sided weakness, left-sided sensory loss, loss of vision from the left side of both eyes, personality changes, neglect of the left side of the body, and lack of recognition of the stroke.
Even after surviving a stroke, you're not out of the woods, since having one makes it a lot more likely that you'll have another. In fact, of the 795,000 Americans who will have a first stroke this year, 23 percent will suffer a second stroke.
Recovering From A Left-Brain Stroke
Though changes after a left-brain stroke are often abrupt and severe, the brain has an incredible ability to adjust and even reconnect neurological pathways. This ability is called neuroplasticity and occurs before you're even born.
Stroke survivors with right-brain injuries frequently have speech and communication problems. Many of these individuals have a hard time pronouncing speech sounds properly because of the weakness or lack of control in the muscles on the left side of the mouth and face.
Rehabilitation and treatment of a right side stroke involves restoring as much function as possible. The side effects listed above can be remedied, at least partially, by participation in the following rehabilitation methods and stroke recovery treatments: Physical Therapy.
Both large strokes and multiple small strokes can cause vascular dementia. Conditions such as old age, prior memory problems, a history of several strokes, or a stroke located in the left side of the brain all seem to increase the likelihood of dementia in the first year after stroke.
The most rapid recovery usually occurs during the first three to four months after a stroke, but some survivors continue to recover well into the first and second year after their stroke. Some signs point to physical therapy.
A left hemispheric stroke happens when blood cannot flow to the left hemisphere (side) of your brain. A stroke caused by a blood clot is called an ischemic stroke. A stroke caused by a burst or torn blood vessel is called a hemorrhagic stroke.
Right Brain
If the stroke occurs in the right side of the brain, the left side of the body will be affected, producing some or all of the following: Paralysis on the left side of the body. Vision problems. Quick, inquisitive behavioral style.
Hemorrhagic strokes are less common, making up about 15 percent of stroke cases, but they are often deadlier, Sozener says. Patients may experience one of the following types: Intracerebral hemorrhage, a weak blood vessel breaking inside the brain.
Overall, the general prognosis of ischemic stroke is considered better than that of hemorrhagic stroke, in which death occurs especially in the acute and subacute phases [2,3].
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.
After six months, improvements are possible but will be much slower. Most stroke patients reach a relatively steady state at this point. For some, this means a full recovery. Others will have ongoing impairments, also called chronic stroke disease.
Aphasia is a language disorder that affects your ability to communicate. It's most often caused by strokes in the left side of the brain that control speech and language.
Because the frontal lobe controls our spatial awareness, a frontal lobe stroke may affect a patient's ability to pinpoint the location of things they see, feel, or hear, and may cause difficulties with navigating the environment.
Damage to the right side of your brain can cause problems with attention, memory, problem solving, and more. Speech-language pathologists, or SLPs, can help.
This may be caused by: A clot from another part of the body that breaks off and becomes trapped in a blood vessel supplying the brain. A clot that forms in an artery that supplies blood to the brain. A tear in an artery supplying blood to the brain.
Unfortunately, blood thinners can reduce the risk of clot-related stroke only to increase the risk of stroke related to bleeding and blood vessel rupture. To prevent unwanted complications from blood thinners, patients may need to make lifestyle and adjustments moving forward.
Driving after a stroke
If you have had a stroke or TIA, you cannot drive for 1 month. Whether you can return to driving depends on what long-term disabilities you may have and the type of vehicle you drive.
