Parkinson’s disease in which there are certain areas of the brain that do not receive an adequate supply of oxygen resulting in spasticity of the legs. There are characteristic changes of the brain around the
ventriclesUltrasound, normal fetus - ventricles of brain
Ultrasound, normal fetus- ventricles of brain (fluid filled spaces) that can easily be picked up on MRI called periventricular leukomalacia. The leg spasticity and weakness is present within a few months of birth.
On the other hand, hereditary spastic paraplegia typically has a genetic component (other family members have the disease which is passed on from one generation to another) and the patients usually don't have symptoms until later on in childhood or when they reach middle age (40-50s). You'll have to talk to your physician about the diagnosis and which one your son fits. If there is any question, consider a pediatric neurologist to help you out. GOod luck.
