Doctors at Iran’s Isfahan University of Medicine recently documented the case of a 23-year-old male whose head dropped to a 90-degree angle because his neck muscles could no longer support it.

Cervical Kyphospholiosis (CKS), aka “Dropped Head Syndrome,” is a serious medical condition characterized by weakness in the neck extensor muscles, which renders them unable to support the weight of the head. It is usually associated with various neuromuscular conditions, including mitochondrial myopathy, congenital myopathy, motor neuron disease, or anatomical abnormalities. such as an unusually large head, but doctors at an Iranian university recently reported a previously undocumented case of CKS caused by years of substance abuse.
