The paper reviews contribution of the Bologna group to the understanding of motor disorders in sleep. Nocturnal myoclonus was first discovered in restless legs syndrome patients: it occurs during NREM light sleep (stages 1- 2) and may be considered the motor accompaniment of the cyclic fluctuations in excitability typical of such stages. Propriospinal myoclonus has recently been reported and may also be modulated by supraspinal control: jerks can in fact be confined to the 'pre-dormitum) and may be responsible for severe imnsonnia. Nocturnal frontal lobe epilepsy occurs during NREM sleep and may be misdiagnosed as parasomnia. Its recognition may often be difficult due to absence of ictal epileptic EEG activity: video-polysomnographics recording of the seizure is mandatory to confirm the diagnosis. REM sleep behavior disorders are an expression of the dissociated REM sleep stages; they can be apparently idiopathic, or associated with narcolepsy but they may also herald by years parkinsonian diseases or multiple system atrophy.
