X-linked spasticity-intellectual disability-epilepsy syndrome

X-linked spasticity-intellectual disability-epilepsy syndrome (also known as Goldblatt syndrome or X-linked spastic paraplegia-intellectual disability-epilepsy syndrome) is a rare genetic neurological disorder that primarily affects males. The condition is characterized by a triad of progressive spastic paraplegia (stiffness and weakness of the legs), intellectual disability of variable severity, and epileptic seizures. The central nervous system is the primary body system affected, with symptoms reflecting dysfunction of both the upper motor neurons (leading to spasticity) and the cerebral cortex (contributing to seizures and cognitive impairment). Affected individuals typically present in infancy or early childhood with developmental delay, followed by the emergence of spasticity in the lower limbs and seizures. The spasticity may be progressive and can significantly impair mobility over time. Intellectual disability ranges from mild to severe. Seizures may take various forms and can be difficult to control with standard antiepileptic medications. Female carriers may be asymptomatic or show mild manifestations due to X-inactivation patterns. There is currently no cure for this condition. Treatment is symptomatic and supportive, focusing on management of spasticity through physical therapy and antispasticity medications (such as baclofen), seizure control with antiepileptic drugs, and educational and developmental support services to optimize cognitive and functional outcomes. Orthopedic interventions may be necessary in some cases to address contractures or skeletal deformities resulting from chronic spasticity.
