Most people who develop Parkinson's disease are 60 years of age or older. (medicinenet.com)
Parkinson's disease is the second most common neurodegenerative disorder and the most common movement disorder. (medicinenet.com)
Characteristics of Parkinson's disease are progressive loss of muscle control, which leads to trembling of the limbs and head while at rest, stiffness, slowness, and impaired balance. (medicinenet.com)

Parkinson's disease was named after the British doctor James Parkinson, who in 1817 first described the disorder in detail as 'shaking palsy. (medicinenet.com)
Most of the movement-related symptoms of Parkinson's disease are caused by a lack of dopamine due to the loss of dopamine-producing cells in the substantia nigra. (medicinenet.com)
Other cells in the brain also degenerate to some degree and may contribute to non-movement-related symptoms of Parkinson's disease. (medicinenet.com)
Although it is well known that lack of dopamine causes the motor symptoms of Parkinson's disease, it is not clear why the dopamine-producing brain cells deteriorate. (medicinenet.com)
In addition, abnormal clumps called Lewy bodies, which contain the protein alpha-synuclein, are found in many brain cells of individuals with Parkinson's disease. (medicinenet.com)

Genetic variants were assessed using the American College of Medical Genetics criteria for pathogenicity. (bmj.com)
The presence of oligogenic variants did not influence the age of onset or disease severity. (bmj.com)
Conclusions A priori, individuals with AD, PD-DLB and FTD-ALS are more likely to harbour a known genetic risk factor, and it is the burden of these variants in combination with rare benign alleles that is likely to be responsible for some oligogenic associations. (bmj.com)
1-5 Some of the known risk alleles are common in the general population, raising the possibility that multiple interacting genetic variants might enhance the risk of developing disease or modify the disease phenotype. (bmj.com)
A view is emerging that the genetic component of the disease may be due to a large number of variants, each of which is very rare (mainly deletions of DNA segments), rather than to a handful of common variants. (dericbownds.net)
It is therefore attempted to elucidate the effect of genetic variants (single nucleotide polymorphisms, SNPs) on gene expression and epigenetic modification of regulatory regions of the genome (DNA methylation). (lifeandbrain.com)

We then will use chemical biology approaches to determine how identified AD variants dysregulate brain blood-brain barrier transport functions to compromise brain health and promote AD risk. (curealz.org)
Effects of genetic variants on the risk of complex diseases estimated from association studies are typically small. (ulaval.ca)
Nonetheless, variants may have important effects in presence of specific levels of environmental exposures, and when a trait related to the disease (endophenotype) is either normal or impaired. (ulaval.ca)
