Why is spastic cerebral palsy caused by lesion in pyramidal tract?

  1. Hello everyone,

    The way I remember upper motor neuron lesions. I always thought a singular lesion in pyramidal tract would only cause Babiniski sign and loss of superficial reflexes. For a UMN to cause spasticty it must affect extra pyramidal motor tracts such as reticulospinal tract.

    But I just read in this website spastic cerbral palsy is pyramidal and non spastic is extrapyramidal. How can that be?

    Also did I understand these terms right

    Plegia : Complete paralysis.
    Diplegia: Lower Limbs affected more than Upper Limb . Isn't this same as paraplegia?
    Quadriplgia: All 4 limbs affected. Are UL more affected than LL.


    Thank you :smile:
