A tremor is defined as cerebellar tremor if it is a pure or dominant intention tremor (uni or bilateral), with a frequency of less than 5 Hz and may sometimes be associated with postural tremor ( Deuschl G et al, 1998). Titubation is a pattern of cerebellar tremor, involving the head and the trunk. It can be noted in various etiologies and degenerative conditions affecting the cerebellum.
These tremors are difficult to treat. Various drugs including anti-cholinergic, 5-Hydroxy-L-Tryptohan, amantadine, propranolol, clonazepam, carbamazepine, tetrahydrocannabinol, weights have been shown variable results in small number of cases/case reports.( Deuschl G et al, 2010; Hallett M et al, 1991; Rascol A et al, 1981; Fox P et al, 2004)
