Parkinson disease (PD) is one of the most wide spread neurodegenerative disorders. In North America alone it affects 1 million people. It is a multifactorial disorder caused by genetic, various biological and environmental factors. One of the important features of PD is the dementia, which is believed to be due to the loss of dopaminergic neurons. In some cases the disease can be inherited as an autosomal dominant or recessive trait but in the majority of \cases it is acquired. The biological causes of the disorder are unknown. The identification of mutations in the parkin gene in the autosomal recessive case and alpha-synuclein gene in autosomal dominant cases has opened a new avenue for studies to understand the basic biochemical mechanisms of pathogenesis. Although several types of treatments such as transplantation of cells that produce L-Dopa and direct gene delivery using adeno-associated viral vectors may correct animal models of PD, their use fulness in the human is not yet clear. A better understanding of the causes of neurodegeneration may lead to better therapies in the future.
