Overview

Kyphoscoliosis-lateral tongue atrophy-hereditary spastic paraplegia syndrome is a very rare inherited neurological condition. It combines three main problems: an abnormal curving of the spine (called kyphoscoliosis), wasting or shrinking of the sides of the tongue (lateral tongue atrophy), and hereditary spastic paraplegia — a condition where the legs gradually become stiff and weak due to damage to the nerve pathways in the spinal cord. This disease belongs to a broader family of conditions called hereditary spastic paraplegias (HSPs), which are sometimes also called familial spastic paraplegias or Strümpell-Lorrain syndrome as a group. The combination of spinal curvature, tongue changes, and leg stiffness makes this particular syndrome distinct from other types of hereditary spastic paraplegia. People with this condition may notice difficulty walking, muscle stiffness in the legs, and changes in their speech or swallowing related to the tongue involvement. The spine curvature can also affect posture and, in some cases, breathing. Because this is an extremely rare syndrome, treatment is focused on managing symptoms rather than curing the underlying cause. Physical therapy, mobility aids, and supportive care are the main approaches used today. Research into this specific syndrome is still in early stages, and most management guidance is borrowed from the broader hereditary spastic paraplegia field.
