Onset
The risk is greatest with cervical spinal cord lesions and is rare with lesions below T6 Thoracic vertebrae. It has rarely been reported in spinal cord lesions as low as T10. The first episode may occur weeks to years after spinal cord injury takes place, but most people at risk (80%) develop their first episode within the first year after injury. Once a person has their first episode of autonomic dysreflexia, the next 7–10 days are critical because there is a high incidence of recurrence within that time. Some people describe this predisposition as an easily excitable autonomic nervous system.

Famous quotes containing the word onset:
“While the onset of puberty can vary by as much as six years, every adolescent wants to be right on the 50-yard line, right in the middle of the field. One is always too tall, too short, too thin, too fat, too hairy, too clear-skinned, too early, too late. Understandably, problems of self-image are rampant.”
—Joan Lipsitz (20th century)
