title: [Tremors].
abstract: Tremor (Tr) is an involuntary rhythmic movement disorder. Its causes are multifold. The physiopathogenesis is complex and only partially understood. The classification, based on clinical grounds distinguishes: 1) Physiological Tr at 8-12 Hz, postural, involving the limbs; 2) Essential Tr at 8 Hz, often familial, postural, involving the limbs; 3) Parkinsonian Tr at 4-6 Hz, present at rest, rarely isolated, often asymmetrical, involving the limbs, sometimes the jaw; 4) Cerebellar Tr at 3-4 Hz, maximal at the end of limb movements. Therapy is based on this classification. The main points for the diagnosis are age of onset, associated signs, toxic factors and heredity.
