Health Assessment 23the debilitating effects of an ischemic stroke is higher in people who do not seek treatment after an episode of TIA. The risk is particularly highest in the first 24 hours, the first week and lessens after a few weeks. So, TIA should be treated as an emergency so that, further complications can be prevented[ CITATION Sor11 \l 16393 ]. In many cases a TIA occurs due to either asymptomatic or symptomatic carotid stenosis, extracranial vertebral artery atherosclerosis or intracranial atherosclerosis [ CITATION Col17 \l 16393 ]. Imaging studies help in the diagnosis of this set of diseases [ CITATION Ueh15 \l 16393 ]. Carotid re-vascularilization is often recommended or patients with severe stenosis[ CITATION Col17 \l 16393 ]. Other therapy may involve an anti-platelet therapy, blood pressure control, reduction of low densitylipoprotein, and extensive lifestyle modification that includes controlling blood glucose levelswithin the normal range. Symptoms experienced by TIA patients are often similar to the those experienced by patients of ischemic stroke. But as the name suggests, these symptoms are of transient nature. Weakness in limb is usually unilateral, slurred speech, monocular blindness or even binocular blindness or blurred vision is experienced by some patients. Limb shaking occurs inTIA patients but does not occur in patients due to ischemic stroke. At times, patients may report hemivisual field vision defects or ataxia of the limbs, but these symptoms may be due to some other underlying cause and are not caused due to Transient Ischemic Attack. Imagingtechniques may help understand the cause of such associated symptoms. How symptoms re perceived by patients and their physicians depends on their gender, education and race[ CITATION Kim14 \l 16393 ].The propensity to suffer from TIA is greater in patients with hypertension, diabetes, dyslipidemias patients who have had a TIA before are advised to follow a prescribed diet, exercise regularly, limit intake of alcohol and cessation of tobacco use. Surgical procedures may have to be done on some patients for revascularisation of the carotid artery. At times
