Parkinson’s Tremor is one of the cardinal features of disease and was described in ancient Indian descriptions of the “kampavata” illness, which probably corresponds to the modern definition of Parkinson’s tremor. Tremor is often the presenting feature of Parkinson’s disease, but it is not a necessary feature for this diagnosis, and ~25% of patients with Parkinson disease in fact never develop tremor. Furthermore, tremor may diminish in later stages of the disease, when bradykinesia becomes more prominent. The typical and rather complex movements of parkinsonian rest tremor indicate Parkinson’s disease with high specificity. They include agonist and antagonist activation alternating in a precisely tuned manner, often leading to a stereotypical series of movements, such as the typical pill-rolling tremor. Tremor in Parkinson’s disease is often more difficult to alleviate than the hypokinetic Parkinson’s disease manifestations (bradykinesia and rigidity). The tremor is not as responsive to dopaminergic therapy as the hypokinesias, or may not improve with medical treatment at all. An analysis of what is known about the pathogenesis of Parkinson tremor may help explain this discrepancy.

The pathologic hallmark of Parkinson’s tremor is the loss of dopamine-producing neurons in the substantia nigra pars compacta especially its ventrolateral portion, which projects to the putamen. This induces a dopaminergic deficit in the striatum, where these neurons form synapses on neurons belonging to two distinct classical corticostriatothalamocortical circuits, known as the indirect and direct pathways. Dopaminergic neurons project to striatal cells that form part of the indirect pathway. These are equipped with inhibitory receptors. Thus, dopamine exerts an inhibitory net effect on the indirect pathway loop, and the dopaminergic deficit of Parkinson’s disease reduces this inhibition. Royal Care Super Speciality Hospital is the only Neuro-Care center in all of India, facilitated with expertise and technology that provides an MRgFUS (Magnetic Resonance guided Focused Ultrasound) therapy to Essential Tremors and Parkinson’s patients with tremors.
