Degenerative disease
Template:Short description Degenerative disease is the result of a continuous process based on degenerative cell changes, affecting tissues or organs, which will increasingly deteriorate over time.<ref name=":3">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
In neurodegenerative diseases, cells of the central nervous system stop working or die via neurodegeneration. An example of this is Alzheimer's disease.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The other two common groups of degenerative diseases are those that affect circulatory system (e.g. coronary artery disease) and neoplastic diseases (e.g. cancers).<ref name=":3" />
Many degenerative diseases exist and some are related to aging. Normal bodily wear or lifestyle choices (such as exercise or eating habits) may worsen degenerative diseases, depending on the specific condition.<ref name=":3" /> Sometimes the main or partial cause behind such diseases is genetic.<ref name=":4">Template:Cite news</ref> Thus some are clearly hereditary like Huntington's disease.<ref name=":5">Template:Cite journal</ref> Other causes include viruses, poisons or chemical exposures, while sometimes, the underlying cause remains unknown.<ref name=":4" />
Some degenerative diseases can be cured. In those that can not, it may be possible to alleviate the symptoms.<ref name=":3" />
