Symptoms and Signs

The classic presentation of Todd's paresis is a temporary weakness of a hand, arm, or leg after partial seizure activity within that limb. When seizures affect areas other than the motor cortex, other transient neurological deficits can occur.


The cause of Todd's paresis is not known but there are two hypotheses to its cause. The first is the depletion theory, where the motor cortex is exhausted resulting to prolonged neuronal hyperpolarization. The second is that there is temporary inactivation of motor fibres caused by activation of NMDA receptors.
