Lacunar Stroke - Oren Zarif - Lacunar Stroke

In the event of a lacunar stroke, the affected area is either the whole face, an arm or leg, or both. These affected areas connect to the brain cortex, which is a part of the nervous system that controls voluntary movements. A stroke in these areas causes an inability to move and may affect a range of other bodily functions as well. Pure motor strokes are also known as hemiparesis, resulting in weakness on one side of the body.

A doctor may administer blood pressure tests and ask you about your symptoms. In some cases, doctors may perform a detailed neurological exam to determine the extent of damage and how quickly the symptoms improve. A doctor may also administer heart function tests. In some cases, the symptoms will go away completely without treatment, known as a transient ischemic attack. However, if the symptoms persist, it is best to seek medical treatment as soon as possible.

A CT scan may be necessary to confirm a diagnosis. CT scans provide detailed images of the brain, but they cannot accurately identify lacunar stroke. MRI, on the other hand, is more sensitive and may be necessary to confirm the diagnosis. Patients who have multiple lesions in their cerebellum will likely undergo an MRI or CT angiography. Although these tests are not a cure for lacunar stroke, they are useful in identifying other conditions.

A study conducted by Chen et al. compared two studies to find out what risk factors are associated with the development of lacunar stroke. Researchers compared MRI scans and the incidence of lacunar stroke in Black people in a majority-Black community. Their findings revealed that black patients are at greater risk of developing this condition than white patients. This research shows that a genetic factor may play a role in the development of lacunar infarcts.

While this study was not designed to determine the precise cause of lacunar stroke, the results showed that patients with mild syndromes showed poorer cognitive performance than those without. The researchers also found that a recent small subcortical infarcts were located mainly near corticospinal tracts related to motor and sensory functions. This type of infarction is associated with changes in emotional health and sleep quality. It is therefore imperative to investigate the cause of these symptoms, which may be associated with lacunar stroke.

Large vessel ischemic strokes are clinically different from lacunar stroke, and a patient with a severe case of carotid stenosis increases the risk of a subsequent stroke. If the lesions are more than 70%, the U.S. Preventive Services Task Force recommends carotid artery intervention in patients with these symptoms. However, in many cases, a thorough embolic workup may not be indicated for patients with lacunar stroke.

In some cases, people with a lacunar stroke can develop dementia. Some of these individuals may experience changes in their abilities in the years after the event. Some cases are associated with fatty deposits in the bloodstream. These fatty deposits build up in the arteries and make them more prone to blockages. Despite the risk, most patients recover fully and resume normal activities. Although they do not necessarily suffer permanent disabilities, those with multiple lacunar strokes may be at increased risk for dementia or emotional behavior.

A patient with a lacunar stroke is at a higher risk for early dementia because it is usually small in size. While the symptoms of a lacunar stroke can vary depending on the location and the cause of the infarction, they usually result in a reduced ability to perform everyday activities. If this is the case, the patient may also develop parkinsonism, which resembles symptoms of Parkinson's disease.

A recent study published in the journal Stroke describes a case of a patient with a lacunar stroke as a small artery that branches directly from the larger main artery. Because lacunar strokes occur in the deep brain, the arteries of this region are small and branch off of this larger artery. High blood pressure can directly damage these arteries and increase the risk of lacunar stroke. Additionally, it can cause atherosclerosis, which forms plaques on blood vessel walls.

Although this type of stroke is relatively uncommon, the mortality and morbidity are high. A good outcome has been achieved by early diagnosis and treatment. This article summarizes the pathophysiology of lacunar stroke, discusses the treatment options, and highlights the importance of the interprofessional team in the patient's care. Also, it highlights the importance of care coordination and the need for antihypertensive therapy. Further, the goal of rehabilitation therapy is to restore neurologic function to the level it was before the onset of the stroke.
