Degeneration (algebraic geometry), the act of taking a limit of a family of varieties; Degenerate bilinear form, a bilinear form on a vector space V whose induced map from V to the dual space of V is not an isomorphism; Degenerate distribution, the probability distribution of a random variable which only takes a single value
Degeneration theory achieved a detailed articulation in Bénédict Morel's Treatise on Degeneration of the Human Species (1857), a complicated work of clinical commentary from an asylum in Normandy (Saint Yon in Rouen) which, in the popular imagination at least, coalesced with de Gobineau's Essay on The Inequality of the Human Races (1855).
Fundus of geographic atrophy. Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision over time.
Alzheimer's disease (AD) is a chronic neurodegenerative disease that results in the loss of neurons and synapses in the cerebral cortex and certain subcortical structures, resulting in gross atrophy of the temporal lobe, parietal lobe, and parts of the frontal cortex and cingulate gyrus. [14]
Degenerative disease is the result of a continuous process based on degenerative cell changes, affecting tissues or organs, which will increasingly deteriorate over time. [ 1 ] In neurodegenerative diseases , cells of the central nervous system stop working or die via neurodegeneration .
The incidence of age-related macular degeneration and its associated features increases with age and is low in people <55 years of age. [101] Smoking is the strongest modifiable risk factor. [102] As of 2008, age-related macular degeneration accounts for more than 54% of all vision loss in the white population in the US. [103]
This degeneration was described as being passed from generation to generation, resulting in imbecility and senility due to hereditary influence. Max Nordau's Degeneration held that the two dominant traits of those degenerated in a society involve ego mania and mysticism. [13]
Degeneration is deterioration in the medical sense. Generally, it is the change from a higher to a lower form. More specifically, it is the change of tissue to a lower or less functionally active form. True degeneration: when there is actual chemical change of the tissue itself.
