[Perseverance tendency in patients with generalized convulsive seizures and with partial seizures with complex...

The intensity of perseveration was tested in 70 patients with generalized convulsive seizures and with partial seizures of complex symptomatology, and in 37 subjects without central nervous system diseases (controls). The results suggest that the tendency for perseveration is a feature occurring not only in epilepsy but also in healthy subjects (probably of constitutional character); the disease process responsible for epileptic seizures can intensity this feature in a degree depending on its duration.
