Lacunar Stroke - Oren Zarif - Lacunar Stroke


A new study by Chen et al. studied the incidence of lacunar stroke, also called infarction, and its risk factors. The researchers used MRI scans of the brain to determine the causes, risk factors, and the prevalence of lacunar stroke. The study concluded that the risk of lacunar stroke increased with advanced age, smoking, high cholesterol, and diabetes mellitus. The authors also noted that there are some common risk factors, including atherosclerosis, smoking, and alcohol consumption.

The vascular system of the brain consists mainly of arterial branches. These arteries form a circle in the middle of the brain. The branches of the cerebral artery include the basilar, vertebral, and middle cerebral arteries. Deep cerebral arteries feed the white and gray matter in the brain. Lacunar stroke occurs when a small penetrating artery becomes blocked or obstructs. These lacunar strokes vary in size, but the majority of them are under 10 mm in size.

If you suspect that you are suffering from a lacunar stroke, visit a doctor right away. Early treatment is crucial to preventing additional strokes and reducing the risk of a full-blown stroke. Treatment for lacunar stroke depends on the type of brain injury. Treatment usually involves medicines to restore circulation and reduce the severity of symptoms. A severe stroke may require physical rehabilitation and even a lifetime of disability. If treatment is not provided in time, the symptoms may return after a few weeks or months.

A lacunar stroke affects both the motor and sensory areas of the brain. The thalamus, which controls voluntary movement, has been damaged in this process. Damage to these areas affects these nerve fibers, and the affected area may experience weakness or loss of motor ability in one arm or leg. The face and eyes are not affected in most lacunar strokes. A person suffering from such a stroke may also suffer from depression, anxiety, or mood swings.

The diagnosis of a lacunar stroke is based on a variety of diagnostic tests. Typically, a CT scan will take detailed images of the brain. Because lacunar strokes are small, they may not show up well on CT imaging. In some cases, another diagnostic test may be performed such as magnetic resonance imaging. A CT angiography will also be conducted to detect any blocked blood vessels. This test is more accurate than CT imaging.

Once diagnosed, patients must undergo physical therapy and occupational therapy. They may also need muscle relaxants to reduce spasticity. Care coordination is essential. Antiplatelet medications are also important, as is ensuring that vascular risk factors are well controlled. Patients must also follow guidelines recommended by their primary care provider to prevent another stroke. The care coordination of treatment for a lacunar infarction is critical to a patient's recovery.

Unlike other types of stroke, the cognitive impairment following a lacunar infarction is not a function of the location of the lesion. It is rather related to the extent of the pathology in small vessel disease, which is often diffuse throughout subcortical tissues. Although lacunar infarction is not known to cause higher-level dysfunction, the clinical findings of this type of stroke should be evaluated and acted upon accordingly.

A single penetrating artery occlusion may lead to a lacunar infarct, which accounts for about a quarter of all cerebral infarcts. Patients with lacunar infarcts usually present with a classic lacunar syndrome. Diabetes mellitus and hypertension are major risk factors. The patients with lacunar infarcts show a paradoxical clinical course: they usually exhibit an initial favourable.

Clinical course, but are more likely to die within a few months. In fact, small vessel disease may lead to a lacunar stroke, and the risk for death is heightened when there is no accompanying disease.

Lacunar stroke can be asymptomatic. However, in many cases the patient may never even experience any symptoms. Because the infarcts are small, the autopsy material is often scanty and difficult to interpret. Studies on stroke risk factors have relied on clinical diagnosis. The findings of this study have supported the hypothesis that there are two distinct types of this type of stroke. So what is a lacunar infarct?
