Reflex epilepsies

Description

Reflex epilepsies are rare epileptic syndromes with seizures induced by specific triggering factors (either by visual, auditory, somato-sensitive or somato-motor stimulation, or by higher cortical function activities). Photosensitive epilepsies are the most frequent form. Spontaneous seizures may also occur. "Reflex seizures'" can be classified into a simple "pure" reflex epilepsy and a complex group. The former comprises seizure triggered by simple sensory stimuli or by movements (photosensitive epilepsies). The latter are triggered by complex mental and emotional processes (verbal and non-verbal epilepsies).

Coding note from above levels

Use additional code, if desired, to identify the type of seizure.
