Parkinson’s disease is an aging-related neurodegenerative disorder of the central nervous system, affecting about 2.5% of people over 70 years of age, which is mainly characterized by resting tremor in the arms and cyclic blocks of muscle movement (especially, in the legs), with gradual impairment of autonomy.
There are also “juvenile” forms of Parkinson’s disease, which start earlier, as early as after age 50, generally less frequent and for which it is often easier to identify a specific cause, such as intoxication with exogenous substances or taking certain medications.
In this case, they are referred to as “parkinsonisms,” as these variants do not exactly coincide with Parkinson’s disease and share only part of its etiopathogenesis, but are characterized by essentially indistinguishable symptoms and anatomopathological features.
