Essential tremor
During maturation, a process occurs that involves progressive neurodegeneration and/or the death of neurons. This process, which can be normal and natural during normal aging, involves the fundamental cells of the nervous tissue and its internal components, which are the ones that prevent effectiveness in conducting information in the human brain, with the appearance of tremors, such as in Parkinson's disease. Essential tremor is the result of abnormal communication between certain areas of the brain, including the cerebellum, thalamus, and brainstem.
