A dummy foal, also known as neonatal maladjustment syndrome (NMS), is a condition that causes neurological symptoms in foals. Foals with NMS appear healthy at birth but soon exhibit neurological abnormalities such as detachment, disorientation, unresponsiveness, confusion, and difficulty nursing. They may also exhibit abnormal, often vague behaviors and/or neurologic signs. NMS is not a disease but rather a broad term that applies to foals that exhibit abnormal behaviors and/or neurologic signs. The cause of NMS is not fully understood, but it is believed to be related to oxygen deprivation during birth. Treatment for NMS may include supportive care, such as providing oxygen and fluids, and medications to control seizures and other symptoms. In some cases, a technique called "squeezing" may be used to help the foal recover. The survival rate for foals with NMS varies depending on the severity of the condition and the promptness of treatment.
