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.

Management:

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)
