Neuropathology of Atypical Parkinsonian Disorders
Although the clinical syndrome of parkinsonism (rigidity, bradykinesia, and tremor) is most often owing to idiopathic Parkinson’s disease (PD), it may also be associated with a variety of other underlying pathologies (Table 1) (1–3). Each of these other pathological conditions tends to have a characteristic clinical phenotype, however atypical cases are increasingly recognized (4–8). Moreover, ...

متن کاملHistorical Issues and Atypical Parkinsonian Disorders
Studying archetypes is a fundamental task in nosography. Duchenne de Boulogne practiced it instinctively, and many others have done it before and after him: It is indispensable, and the only way to extract a specific pathological state from the chaos of imprecision. The history of medicine, which is long and grand, shows this truth well. But once the archetype is established, the second nosogra...
متن کاملNeurogenetics II: complex disorders.
The genetic analysis of common neurological disorders will be a difficult and protracted endeavour. Genetics is only one of many disciplines that will be required but it has already thrown considerable light on the aetiology of several major neurological disorders through the analysis of rare inherited subgroups. The identification of individual susceptibility genes with variants of smaller eff...
