Symptoms of vertebrobasilar insufficiency, or VBI, include difficulty speech, vision loss in one or both eyes, nausea, vomiting and numbness in the limbs, reports Healthline. Symptoms of VBI and stroke are similar. They vary depending upon the severity of the condition and may be temporary or long-term. Other symptoms of vertebrobasilar include balance and coordination problems, vertigo, weakness and mental problems.
Symptoms of VBI require immediate medical attention, states Healthline. The main cause of the problem is atherosclerosis, which is hardening and obstruction of the arteries, restricting the flow of blood to the brain. Smoking, obesity, diabetes and hypertension may render a person vulnerable to the condition.
A physical assessment, blood tests, magnetic resonance imaging and CT scans may help diagnose the condition, according to Healthline. The doctor may perform magnetic resonance angiography and, in less common cases, recommend a lumbar puncture to help determine the specific cause of the condition and best treatment option.
Treatment includes staying physically active, shedding extra pounds, quitting smoking and taking prescription medications, explains Healthline. Medications manage diabetes and blood pressure, thin blood and lower the levels of cholesterol. Surgery helps to improve blood flow to the brain, counteracting the problem. Eating a diet that contains plenty of fruits and vegetables may help prevent the problem.
