Description
Hereditary Spastic Paraplegia (HSP) 63, also known as SPG63, is a rare and complex form of HSP.
Characteristics:
- Onset in infancy with spastic paraplegia, presenting with delayed walking and a scissors gait
- Associated with short stature and normal cognition
- Periventricular deep white matter changes in the corpus callosum are noted on brain imaging
Cause: SPG63 is caused by a homozygous mutation in the AMPD2 gene (1p13.3) [11][11].
This form of HSP is extremely rare and complex, with a distinct set of characteristics that differentiate it from other forms of the disorder.

Signs and Symptoms
Hereditary Spastic Paraplegia (HSP) 63, also known as SPG63, is a rare and complex form of HSP characterized by an onset in infancy of spastic paraplegia. The primary symptom of HSP is difficulty walking due to spasticity and weakness in the legs [3]. Both legs are affected, usually to a relatively similar degree.
The initial symptoms may include:
- Difficulty with balance
- Weakness and stiffness in the legs
- Muscle spasms
- Dragging the toes when walking
In some forms of HSP, other symptoms such as urinary bladder disturbance, spasticity, abnormal gait, decreased vibration sensation in the toes, and mild upper extremity hyperreflexia may also be present [1][5].
It's worth noting that the symptoms of SPG63 can vary from person to person, but generally, they are similar to those of other forms of HSP. The disease typically progresses gradually over time, with most patients losing the ability to walk by 60 to 70 years of age [9].
Additional Symptoms
- Muscle spasms
- Abnormal gait
- Urinary bladder disturbance
- Decreased vibration sensation in the toes
- Difficulty with balance
- Dragging the toes when walking
- Mild upper extremity hyperreflexia
- weakness
- spasticity
Diagnostic Tests
Hereditary Spastic Paraplegia (HSP) 63, also known as SPG63, is a rare and complex form of HSP characterized by an onset in infancy of spastic paraplegia. Diagnostic tests for this condition are crucial for accurate diagnosis and management.
Electrophysiologic studies: These studies can assess peripheral nerve, muscle, dorsal column, and corticospinal tract involvement in patients with HSP (Source: [6]). This can help identify the extent of neurological damage and guide treatment decisions.
Genetic testing: Genetic testing for SPG4/spastin mutations is available commercially and can provide laboratory confirmation of the diagnosis (Source: [9]). This test can be applied to patients with a clinical suspicion of spastic paraplegia, including those with HSP 63.
Imaging studies: Brain imaging may show periventricular deep white matter changes in the corpus callosum, which is a characteristic feature of SPG63 (Source: [1]). This can help confirm the diagnosis and rule out other conditions that may present similarly.
Neuropsychological evaluations: These evaluations can assess cognitive function and identify any neuropsychological deficits associated with HSP 63. This information can be used to develop personalized treatment plans and improve patient outcomes.
Other ancillary testing: Additional tests, such as blood work and metabolic panels, may be performed to rule out other conditions that may present similarly to HSP 63. These tests can help identify underlying metabolic or genetic disorders that may contribute to the development of this condition.
It's essential to note that a comprehensive diagnostic evaluation for HSP 63 should involve a multidisciplinary team of healthcare professionals, including neurologists, geneticists, and other specialists as needed. Accurate diagnosis and management of this rare condition require a thorough understanding of its complex clinical presentation and the use of various diagnostic tests.

Treatment
Hereditary Spastic Paraplegia (HSP) is a group of rare genetic disorders that affect the nervous system, leading to progressive muscle weakness and stiffness in the legs. While there are no treatments that can prevent or reverse HSP, various drug therapies have been explored to manage its symptoms.
Medications for Muscle Relaxation
Several medications have been used to reduce muscle spasticity in patients with HSP:
- Baclofen: An oral medication that has been prescribed as a muscle relaxant to reduce spasticity [9].
- Tizanidine: Another oral medication that has been used to manage muscle stiffness and spasms.
- Gabapentin/Pregabalin: Oral medications that have been prescribed to reduce muscle spasticity by affecting the way nerve signals are transmitted.
Botulinum Toxin Injections
In addition to oral medications, botulinum toxin injections have also been explored as a treatment option for HSP. These injections can help relax muscles and reduce spasticity [7].
Other Therapies
While not directly related to drug treatments, it's worth noting that other therapies such as physical therapy and muscle relaxers may be used in conjunction with medications to manage symptoms.

Differential Diagnosis
Differential Diagnosis of Hereditary Spastic Paraplegia
Hereditary spastic paraplegia (HSP) is a syndromic designation for inherited neurologic disorders in which the predominant symptom is lower extremity spastic weakness. The differential diagnosis of HSP is broad and includes various conditions that can present with similar symptoms.
Structural Abnormalities of the Brain and Spinal Cord
- Structural abnormalities involving the spinal cord, such as syringomyelia or tethered cord syndrome, can mimic the symptoms of HSP [12].
