Cerebellar Stroke - Signs and Symptoms - Oren Zarif - Cerebellar Stroke
Although cerebellar stroke is rare and only makes up 10% of all strokes, if left untreated, mortality is 40% and half of the survivors experience long-term deficits. Cerebellar strokes can be characterized by a wide spectrum of symptoms, from ataxia to vertigo. Some risk factors include cigarette smoking, diabetes mellitus, and high blood pressure. However, there is a small amount of published information to guide neurologists in their clinical decision-making.

The neurologic signs and symptoms of cerebellar stroke are typically nonspecific, depending on the location and extent of the lesion. A thorough history and neurological examination are the first steps in diagnosing cerebellar stroke. There are several types of cerebellar stroke. The following information may help you determine the most appropriate treatment. In most cases, cerebellar stroke is accompanied by signs of brainstem infarction, including: headache, ipsilateral truncal ataxia, and dysmetria.

Some of the signs and symptoms of cerebellar stroke include ataxia, dysarthria, intention tremor, and clumsiness. Patients may also experience memory problems, poor motor planning, and scanning speech. Early diagnosis of cerebellar stroke is vital to ensuring the best recovery. Patients should seek medical attention if any of these symptoms persist for more than a few weeks. In some cases, cerebellar stroke can lead to hydrocephalus, which may cause brainstem compression and hydrocephalus.

Although the cause of cerebellar stroke remains uncertain, a revised classification of cerebellar infarcts may uncover unrecognized associations between various etiologic subtypes. Small cortical infarcts are characterized by oblique orientation on MRI and may be a precursor to cardiac embolism. Those with smaller infarcts may be at greater risk for the latter.

Patients with symptoms of cerebellar infarction or hemorrhage should be diagnosed promptly. Early diagnosis of cerebellar hemorrhage or infarction may help in the proper treatment. A debilitating hematoma can compress the brain stem or cause a cerebellar herniation, which can be fatal. Surgery may be necessary to remove the hematoma and prevent the patient from deteriorating.

Some common risk factors for cerebellar stroke include blood clots, trauma, and traumatic injury to the back of the head. Smoking, high blood pressure, and elevated cholesterol and fat levels are among the risk factors. Heart disease, traumatic injury to the head, and a ruptured brain aneurysm are also risk factors. Injuries to the neck and head can also damage blood vessels, interfering with the regular flow of blood.

While the specific cause of cerebellar stroke is unknown, recent research has shown that psychiatric disorders may be associated with cerebellar pathology. This has significant implications for patients with schizophrenia and dementia. If you or a loved one suffers from cerebellar stroke, consider talking to your physician as soon as possible. The results of the study could change the course of treatment. There are several types of treatments available, including pharmacological treatment.

Isolated cerebellar stroke patients have a better prognosis than those with larger cerebral infarctions, although more studies are needed. In this study, patients with an isolated cerebellar stroke recovered well within 90 days. However, the prognosis of patients with larger cerebellar infarctions should be monitored carefully to determine whether larger cerebellar strokes are associated with clinically significant deterioration.

Although the cause of cerebellar infarcts remains unclear, it has become increasingly common to identify very small ones. The small cerebellar infarcts, with a diameter of less than 2 cm, are deserving of greater attention. To better understand these brain lesions, we reviewed terminology, mechanisms, and classification system for very small infarcts. We used a targeted search strategy to identify relevant studies published in English language and restricted to the period before February 21, 2013.
