What are the symptoms of ischemia of the brain?

As a medical professional with expertise in neurology, I can provide you with a detailed explanation of the symptoms associated with brain ischemia. Brain ischemia can present with a variety of symptoms, which may vary depending on the severity and the specific area of the brain affected. Here are some common symptoms: 1. Sudden numbness or weakness: This can occur on one side of the body, particularly the face, arm, or leg. 2. **Confusion or trouble speaking and understanding speech**: The individual may have difficulty forming words or comprehending what others are saying. 3. **Sudden trouble seeing in one or both eyes**: This could include blurred vision, blackening of the vision, or double vision. 4. **Sudden trouble walking, dizziness, or loss of balance and coordination**: The person may stumble or have an unsteady gait. 5. Sudden severe headache: This is often described as the worst headache of one's life and may be accompanied by vomiting, seizures, or altered consciousness. 6. Loss of consciousness or fainting: This can occur if the brain does not receive enough blood flow to maintain consciousness. 7. Difficulty swallowing: This can lead to choking or coughing when eating or drinking. It's important to note that these symptoms can be transient, lasting only a few minutes, or they can be persistent, indicating a more severe and lasting ischemic event. The acronym FAST can be used to remember the key warning signs of a stroke: Face drooping, Arm weakness, Speech difficulty, and Time to call emergency services.

Brain ischemia (a.k.a. cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke.
