What is Hereditary Spastic Paraplegia?
Written by Medicover Team and Medically Reviewed by Dr Jaypal Ramdhan Ghunawat , Neurologist
Hereditary Spastic Paraplegia (HSP) is a group of inherited neurological disorders that mainly affect the spinal cord and legs. It causes progressive stiffness (spasticity) and weakness in the lower limbs due to damage to the nerves that control muscle movement. Over time, walking becomes increasingly difficult as the condition worsens.
Is Hereditary Spastic Paraplegia a Common Condition?
Hereditary Spastic Paraplegia is considered a rare condition, and its exact prevalence is hard to pinpoint. Many cases go undiagnosed or are mistaken for other neurological disorders. However, it's generally believed to affect between 1 and 5 people in every 100,000 worldwide.
Types of Hereditary Spastic Paraplegia
HSP can be classified into two main types: pure and complex.
Pure HSP
Pure HSP is characterized by spasticity and weakness confined to the lower limbs, without additional neurological symptoms. This form is more common and generally has a better prognosis.
Complex HSP
Complex HSP includes additional neurological or systemic symptoms, such as cognitive impairment, epilepsy, ataxia, and peripheral neuropathy. The prognosis for complex HSP can vary depending on the severity and range of symptoms.
What Are the Symptoms of Hereditary Spastic Paraplegia?
Hereditary Spastic Paraplegia (HSP) can affect people in different ways. In most cases, the symptoms develop slowly and worsen over time. The condition mainly affects the legs, leading to stiffness and weakness that can impact walking and balance.
Common Symptoms
- Trouble walking or frequent tripping
- Fatigue after light activity
- Severe difficulty walking
- Trouble controlling the bladder
- Speech or swallowing problems (in more complex types)
- Poor hand coordination
What Are the Different Types of Hereditary Spastic Paraplegia?
Hereditary Spastic Paraplegia (HSP) isnt a single condition. It includes many types that differ in symptoms and severity. Doctors usually group HSP into two main forms: pure and complex.
Pure HSP
This is the more common form. What it looks like
- Stiff and weak leg muscles
- Trouble walking
- Mild bladder issues
- No major problems with thinking or senses
Many people with pure HSP stay active and manage daily tasks on their own.
Complex HSP
This type includes leg stiffness along with other symptoms. You might also see
- Speech or swallowing trouble
- Learning difficulties
- Seizures
- Vision or hearing problems
- Poor balance or coordination
Complex HSP may need more support depending on how it affects the body.
What About Genetic Types?
HSP is linked to many different genes. Each one has a label like SPG4, SPG7, etc.
- SPG4 is the most common gene type seen in pure HSP.
- Other types may cause either pure or complex symptoms.
What Causes Hereditary Spastic Paraplegia and Whos at Risk?
Hereditary Spastic Paraplegia (HSP) is a genetic condition. This means it runs in families and is passed down through genes. It mainly affects the nerves in the spinal cord, leading to stiff and weak leg muscles over time.
Causes of Hereditary Spastic Paraplegia
HSP happens when certain genes don't work as they should. These gene changes can stop the nerves from sending signals properly.
- Most cases are inherited from one or both parents
- Gene types like SPG4, SPG3A, or SPG7 are often involved
- The damaged nerves are usually the ones that control leg movement
Risk Factors for Hereditary Spastic Paraplegia
Some people are more likely to develop HSP because of their family history or background.
- Family history: If a parent has HSP, there's a chance it can be passed on
- Inherited patterns: It can be passed in different ways, dominant, recessive, or X-linked
- Close family marriages: These can raise the chance of certain types of HSP
- Age: Symptoms can show up in childhood or later in adulthood

Get Second OpinionHow Is Hereditary Spastic Paraplegia Diagnosed?
Hereditary Spastic Paraplegia (HSP) can be tricky to diagnose because its symptoms often look like other nerve or muscle problems. To get the right diagnosis, doctors take a close look at your symptoms, medical history, and family background.
Steps in Diagnosing HSP
Doctors usually begin with a physical and neurological exam to check your reflexes, muscle strength, and walking pattern. If HSP is suspected, they may suggest a few more tests.
- MRI Scan: Shows if there's damage in the brain or spinal cord
- Genetic Testing: Looks for gene changes linked to HSP
- Nerve and Muscle Tests (EMG, NCV): Checks how well your nerves and muscles are working
- Blood Tests: Helps rule out other causes of your symptoms
What Are the Treatment Options for Hereditary Spastic Paraplegia?
Hereditary Spastic Paraplegia doesnt have a cure, but there are ways to manage symptoms and improve daily life. Treatment focuses on reducing muscle stiffness, improving movement, and helping you stay as independent as possible. Care plans vary based on how mild or severe the symptoms are.
Medications
- Doctors may prescribe muscle relaxants like baclofen, tizanidine, or diazepam to ease stiffness and improve leg movement.
- These medicines usually start showing results within a week or two. For tightness in specific muscles, botulinum toxin injections may be used.
- They typically take effect in about two weeks and may need to be repeated every few months.
- If pain or swelling is present, short courses of anti-inflammatory medication may help.
- Your doctor will monitor how well these treatments work and adjust them as needed.
Physical and Occupational Therapy
- Therapy plays a key role in managing HSP. Physical therapy includes stretching, strength training, and balance exercises to help you move better and avoid joint problems.
- Gait training can improve the way you walk and reduce the risk of falling.
- Occupational therapy focuses on making everyday activities easier, like getting dressed, cooking, or working.
- Most people begin to feel better with consistent therapy over 8 to 12 weeks and often continue with home exercises after that.
Surgical Treatment
- In severe cases where other treatments don't help enough, surgery might be considered.
- Procedures like tendon release can ease tightness and improve mobility.
- If stiffness affects a large part of the body, a baclofen pump may be placed to deliver medicine directly to the spine.
- Surgery may also be needed if there are deformities in the limbs or spine that affect posture or walking.
- Recovery times vary, but most people begin rehab within a few weeks after the procedure.
Assistive Devices
- Using braces, walkers, or wheelchairs can make a big difference in daily comfort and safety.
- These tools help reduce fatigue, prevent falls, and make it easier to move around at home, school, or work.
When Should You See a Doctor?
If your legs feel stiff, weak, or heavy for more than a couple of weeks, its a good idea to see a doctor. These signs could point to Hereditary Spastic Paraplegia (HSP), especially if they slowly get worse over time.
You should also get checked if you
- Trip or lose balance more often than usual
- Find it hard to walk or lift your feet while walking
- Have a parent or sibling with similar walking problems
- Notice bladder issues along with leg stiffness
- Had normal movement before but now I feel it's changing
Even if your symptoms are mild, don't wait too long. Getting help early can make a big difference.
Who Might Be at Higher Risk?
Some people are more likely to develop HSP. This includes those with a family history of the condition or those from families where close relatives have married. Children with delayed walking or unusual walking patterns should also be checked early.
Why It's Important to Act Early?
HSP can't be cured, but early treatment can help manage symptoms and slow things down. The sooner you know what's going on, the better your chances of staying active and independent.

Can Hereditary Spastic Paraplegia Be Prevented?
Hereditary Spastic Paraplegia (HSP) is passed down through genes, so it can't be fully prevented. But there are some smart steps you can take to manage risks and catch symptoms early.
What Can You Do?
Even though you can't stop the condition from being inherited, you can still take action to prepare and protect your health.
- Know your family history: If others in your family have HSP, it's a good idea to talk to a doctor or genetic counselor.
- Consider genetic counselling: Couples with a family history of HSP may benefit from genetic advice before having children.
- Look out for early signs: If you or your child starts to show signs like leg stiffness or walking trouble, don't wait. Early care can help slow things down.
- Stay active and healthy: Regular movement, a balanced diet, and healthy habits can support your muscles and nerves.
