[Non-epileptic paroxysmal disorders in pre-school children].

Paroxysmal events are commonly encountered in toddlers. These events include a variety of conditions with different manifestations and pathophysiology. For that reason, the diagnosis of these events can be challenging. In some instances, studies such as EEG and polysomnogram may be useful to differentiate between epileptic and non-epileptic events. In the majority of cases, a complete clinical history is enough to make an appropriate diagnosis. In this article, we review some of the most common paroxysmal non-epileptic events affecting toddlers, such as: tics, dyskinesias, sleep related events, etc. We also discuss diagnostic strategies and treatment options.
