ABSTRACT
Although a relationship between sleep and epilepsy is well recognized and some sleep related epileptic syndromes are
better characterized, those epilepsies which manifest through motor behaviors during sleep are less known. This paper
offers a brief review about the clinical, diagnostic and therapeutic aspects of seizures that manifest through complex
motor behavior during sleep. In last two decades, three kind of seizures have been described: a) Episodic Nocturnal
Wanderings are featured by complex behavior, which includes leaving the bed, walking, taking things and even violent
behavior; b) Nocturnal Paroxysmal Dystonia consists of brief and highly stereotyped dystonic movements of head, trunk
and limbs; and, c) Paroxysmal Arousals are episodes characterized by sudden eyes opening and facial expressions of fear
or confusion. They are more frequent in men, with an onset between 10 and 20 years old. Clinical assessments, EEG and
imaging studies use to be normal. The polysomnogram with audiovisual monitoring is necessary to document the
disorder. Events are present during stage 2, 3 and 4 of non rapid eye movements sleep. The focus of epileptic activity is
predominantly located in frontal lobe, but also, although less frequently, in temporal lobe. Treatment with antiepileptic
drugs, especially carbamazepine, produces notable improvement. These sleep related motor behaviors should be taken
into account during the assessment of typical parasomnias and diurnal excessive sleepiness.
