G40-G47: Episodic and paroxysmal disorders
G46: Vascular syndromes of brain in cerebrovascular diseases
Vascular syndromes of the brain in cerebrovascular diseases are a group of conditions that occur when the brain's blood vessels are impaired, disrupting the supply of blood to the brain. They're caused by various forms of cerebrovascular diseases such as stroke, transient ischemic attack (TIA), or chronic cerebrovascular diseases. This disruption can lead to different syndromes depending upon the area of the brain that is affected, each with its own set of symptoms. Symptoms can vary widely but often include sudden weakness, difficulty speaking, vision problems, balance issues, dizziness, or severe headaches. These vascular syndromes, depending on their severity and the speed of medical intervention, can either resolve without long-term issues, can cause permanent damage like paralysis, or may even be fatal. They progress rapidly, and given their impact on the brain, they affect multiple systems in the body.
