What is Hereditary Spastic Paraplegia ?

Hereditary Spastic Paraplegia (HSP) is a group of rare, inherited neurological disorders that primarily affect the lower extremities. It is characterized by progressive stiffness and weakness in the legs, resulting in difficulty walking and an abnormal gai


Hereditary Spastic Paraplegia (HSP) is primarily caused by genetic mutations that affect the development and function of nerve cells in the spinal cord and brain. HSP can be inherited in an autosomal dominant, autosomal recessive, or X-linked pattern, depending on the specific genetic mutation.

Autosomal dominant inheritance means that a person only needs to inherit one copy of the mutated gene from one parent to develop the condition. This is the most common type of inheritance pattern for HSP, accounting for about 70% of cases. Autosomal recessive inheritance means that a person needs to inherit two copies of the mutated gene, one from each parent, to develop the condition. This accounts for about 20% of cases. X-linked inheritance means that the mutated gene is located on the X chromosome and primarily affects males, who have only one X chromosome.


Some common symptoms of HSP include:

  1. Stiffness and weakness in the legs: HSP primarily affects the lower extremities, causing stiffness and weakness in the legs that can make it difficult to walk and maintain balance.

  2. Abnormal gait: As a result of the stiffness and weakness, individuals with HSP often have an abnormal gait, such as walking on their toes or shuffling their feet.

  3. Spasticity: HSP can cause increased muscle tone and spasms, making it difficult to move the legs smoothly.

  4. Urinary and bowel problems: In some cases, HSP can cause difficulty with urinary or bowel control, such as frequent urination or constipation


Some possible treatments for HSP include:

  1. Physical therapy: Physical therapy can help improve mobility, strength, and balance. This may include exercises to improve muscle strength and range of motion, as well as assistive devices like braces or walkers.

  2. Occupational therapy: Occupational therapy can help individuals with HSP adapt to the challenges of daily life. This may include strategies for conserving energy, modifying activities, and using assistive devices.

  3. Medications: Medications may be used to manage spasticity, pain, or other symptoms of HSP. These may include muscle relaxants, anti-spasticity medications, or pain relievers.

  4. Surgery: In some cases, surgery may be recommended to correct deformities or relieve pressure on the nerves.

  5. Genetic counseling: Genetic counseling may be recommended for individuals with HSP and their families. This can help individuals understand the inheritance pattern and the risks of passing on the condition to future generations.
