La maladie de Parkinson est de nature chronique et évolutive. Retraite Plus vous explique les 4 principaux stades de cette maladie neurodégénérative.


Recently, Braak and coworkers proposed a pathologic staging scheme for Parkinson disease (PD). In this staging, scheme substantia nigra pathology occurs at midstage disease, while involvement of anterior olfactory nucleus, medulla, and pontine tegmentum occur earlier. In the last stages, Lewy bodies (LBs) involve cortical areas.

Parkinson’s disease (PD) is a neurodegenerative disorder for which there is no cure. Most patients suffer from sporadic PD, which is likely caused by a combination of genetic and environmental factors. Braak’s hypothesis states that sporadic PD is caused by a pathogen that enters the body via the nasal cavity, and subsequently is swallowed and reaches the gut, initiating Lewy pathology (LP Recently, Braak and coworkers proposed a pathologic staging scheme for Parkinson disease (PD). In this staging, scheme substantia nigra pathology occurs at midstage disease, while involvement of anterior olfactory nucleus, medulla, and pontine tegmentum occur earlier.

“The breakthrough in the field was that they proposed that the process starts nowhere near the substantia nigra,” says John Duda of the Philadelphia Veteran’s Affairs Medical Center.

They do this by producing a chemical called dopamine that Parkinson’s disease is a progressive neurological disorder. Its first signs are problems with movement. A combination of lifestyle changes, medication, and other treatments can help someone with Parkinson’s maintain a good quality of life. A loss of dopamine characterizes a disorder of the Central Nervous System, Parkinson's disease- the chemical transmitter used to communicate to the muscles and allow for smooth mobility. Parkinson's is a slowly progressing disease.

proposed that cases with Lewy pathology in the peripheral nervous sytem, spinal cord and brain stem are prodromal Parkinson’s disease (PD), suggesting a hypothesized progression of PD pathology. However, the putative potential of peripheral α-synuclein to promote brain pathology has been questioned recently.

Parkinson's disease is a neuro degenerative movement disorder due to Dopamine deficiency. Unlike the Braak staging scheme for Parkinson’s disease (Braak et al., 2003), the unified staging system for Lewy body disorders that was used in the study of Galiano-Landeira et al. (2020 ) was expressly developed to fit the diversity of diseases that feature Lewy pathologies and not just Parkinson’s disease ( Fig. 1 ). Braak staging refers to two methods used to classify the degree of pathology in Parkinson's disease and Alzheimer's disease. These methods are used both in research and for the clinical diagnosis of these diseases and are obtained by performing an autopsy of the brain. Se hela listan på Braak et al.
