9) Transient ischemic attack and its associated signs and symptoms
Contrary to a full-blown stroke attack, a transient ischemic attack (TIA) or also known as a mini-stroke is a condition in which there is a temporary lack of blood supply towards the brain. This condition also causes signs and symptoms similar to stroke, but they are not as severe and may last for less than 24 hours without causing permanent disabilities. Sometimes, this condition may present with a specific visual disturbance known as amaurosis fugax or transient monocular blindness (TMB). It is characterized by a sudden dimming or obscuring of the visual field in one eye leading to blurring and the grayish appearance of the surrounding objects. Exposure to direct sunlight or bright light may aggravate the condition.
Often these symptoms are gone by the time you seek medical attention, and you may not have active signs and symptoms by the moment you’re in front of your doctor.
Although its signs and symptoms are of shorter duration and may not cause major discomfort, most doctors believe that a mini-stroke can be a predisposing factor that leads to ischemic stroke later in life (1 in 3 patients may experience a stroke after having a mini-stroke). Knowing the above-mentioned warning signs and symptoms of stroke or mini-stroke can help you seek quick medical intervention and treatment you need as early as possible. Your doctor will determine what type of stroke you experienced depending on the clinical assessment and investigations.
