Your babyâs soft spot is actually two spots called fontanels â one toward the front of that sweet little head; another smaller one toward the back â and theyâre gaps between the bones of your babyâs skull. And though it may seem as if your babyâs soft spots were put there to make you nervous, they actually plays an important role.
Stroke Home > Cause of Mini-Strokes. A transient ischemic attack (also known as a TIA or mini-stroke) is caused by a temporary lack of oxygen- or nutrient-rich blood to a part of the brain. This lack of blood flow occurs because a blood vessel becomes severely narrowed or blocked.
A transient ischemic attack (TIA) is a transient episode of neurologic dysfunction caused by ischemia (loss of blood flow) â either focal brain, spinal cord, or retinal â without acute infarction (tissue death). TIAs have the same underlying cause as strokes: a disruption of cerebral blood flow (CBF), and are often referred to as mini-strokes. Symptoms caused by a TIA resolve in 24 hours or less.[1][2] TIA was originally defined clinically by the temporary nature of less than 24 hours of the associated neurologic symptoms.
