👉 Vasoparesis is a medical condition characterized by a loss of muscle and/or nerve function, often due to injury or disease. This can include conditions like spinal cord injuries, brain damage, stroke, heart attack, and other diseases that affect the nervous system. It can also be caused by certain medications, such as chemotherapy drugs, which can reduce blood flow to the brain. Vasoconstriction (the dilation of blood vessels) is one common type of vasoparesis.
