  • Title: [Rudimentary psychomotor seizures and their differential diagnosis].
    Author: Karbowski K.
    Journal: Schweiz Rundsch Med Prax; 1990 Jun 12; 79(24):772-6. PubMed ID: 2367770.
    Abstract:
    Clinically it is often very difficult to distinguish rudimentary psychomotor seizures from absence seizures and sudden nonepileptic disturbances, especially from transitory cerebral ischaemia. In contrast to absence seizures during which bifrontally accentuated spike-wave activity is registered in the EEG, absence like psychomotor seizures usually present with unilateral temporal or frontotemporal EEG discharges. Syncopal and psychomotor attacks may overlap in the following context: falls resembling syncope during psychomotor seizures, the so-called "temporal fainting spells"; cardiac arrhythmias during psychomotor attacks; psychomotor symptoms such as automatisms and/or "dreamy states" that occur during syncopal attacks with transient dysfunction of the limbic system; alternating psychomotor and syncopal attacks in the same patient Symptoms of intermittent vertebrobasilar insufficiency: non-systematic vertigo, brief blurring of consciousness and blackouts may all be misinterpreted as rudimentary psychomotor seizures. The further differential diagnosis includes psychogenic attacks as well as states of confusion due to a variety of diseases in internal medicine.
