Spinal deformities occur when the spine contains unnatural curves, and can be caused by defect or injury. Scoliosis, kyphosis and spondylolisthesis are common conditions that fall under spinal deformities. The typical symptoms involve pain and reduced movement.

Spinal stenosis is a narrowing of spaces in the spine that results in pressure on the spinal cord or nerve roots.
Spine tumors may be intrinsic to the spinal cord or nerve roots or they may be metastatic tumors from cancer elsewhere in the body, such as the lung or breast.
Subarachnoid hemorrhage results from the bleeding of an artery around the base of the brain. It is the least common type of stroke, accounting for about 5 percent of all strokes.
Syringomyelia is a condition in which a cavity forms in the spinal cord and fills with cerebrospinal fluid, the liquid that cushions your brain and spinal cord.
Traumatic brain injury (also referred to as TBI) is defined as a blow or jolt to the head, or a penetrating head injury that disrupts the function of the brain.
