Abstract
Movement disorders encompass nervous system abnormalities responsible for the onset of abnormal involuntary movements both due to an excess of movement (so-called hyperkinetic disorders, which include tics, chorea, dystonia, tremor, and myoclonus) and due to slow, reduced movement (so-called hypokinetic disorders, mainly Parkinsonian syndromes). In all of them, regardless of their cause, an abnormality occurs in the normal functioning of the motor pathway of the basal ganglia. Tremor is a rhythmic, oscillatory movement which, according to its presentation (rest, postural, or kinetic), frequency (Hz), and topographic distribution, is due to different causes which have clinical particularities and different treatment and prognoses. Myoclonus refers to sudden, brief muscle spasms due to a neuronal discharge that cannot be voluntarily suppressed. It has different etiologies and treatments according to the origin, distribution, and form of presentation. This update will describe these aspects of tremor and myoclonus.
