Brain imaging shows white matter abnormalities in the periventricular and other regions.	Is a	True	Complicated hereditary spastic paraplegia	Inferred relationship	Some
Spastic paraplegia-severe developmental delay-epilepsy syndrome is a rare, genetic, complex spastic paraplegia disorder characterized by an infantile-onset of psychomotor developmental delay with severe intellectual disability and poor speech acquisition, associated with seizures (mostly myoclonic), muscular hypotonia which may be noted at birth, and slowly progressive spasticity in the lower limbs leading to severe gait disturbances. Ocular abnormalities and incontinence are commonly associated. Other symptoms may include verbal dyspraxia, hypogenitalism, macrocephaly and sensorineural hearing loss, as well as dystonic movements and ataxia with upper limb involvement.
