Tremor may be defined as an involuntary movement that is rhythmic (i.e., regularly recurrent) and oscillatory (i.e., rotating around a central plane). Tremor has its own rich clinical phenomenology and there are variety of ways to classify it.
Pathophysiology[edit | edit source]
Tremor's Pathophysiology is still a debatable topic. The researchers have been unable to identify a particular cause for tremors due to the complex nature of the condition. A hypothesis given in a 2014 article the pathogenesis of both classic tremor and essential tremor is hypothesized to be caused by cerebello–thalamo– cortical network. The difference appears to be in how this network is activated to oscillate. In classic tremor, the setting is stability of a body part where an abnormal beta rhythm synchronizes the basal ganglia and in a mechanism still to be elucidated triggers the cerebellar network. In essential tremor, the abnormality appears to be in the cerebellar network itself, and dysfunction of the motor controller for generating an action sets off the oscillation. Clearly much more data are needed to verify these hypotheses.
