Enhancement gene therapy - the talented

This is a site-wide search. An organism inherits some genes from each parent and thus the parents pass on certain traits to their offspring. Gene therapy and genetic engineering are two closely related technologies that involve altering the genetic material of organisms. The distinction between the two is based on purpose. Gene therapy seeks to alter genes to correct genetic defects and thus prevent or cure genetic diseases. Genetic engineering aims to modify the genes to enhance the capabilities of the organism beyond what is normal. Ethical controversy surrounds possible use of the both of these technologies in plants, nonhuman animals, and humans. enhancement gene therapy Enhancement gene therapy

Alzheimer's disease ADalso referred to simply as Alzheimer'sis a neurodegenerative disease that usually starts slowly and progressively worsens. The cause of Alzheimer's disease is poorly understood. The strongest genetic risk factor is enhqncement an allele of APOE. No treatments stop or reverse its progression, though some may temporarily improve symptoms.


As ofthere were approximately The course of Alzheimer's is generally described in three stages, with a progressive pattern of cognitive and functional impairment. As the disease progresses so does the degree of memory impairment. The first symptoms are often mistakenly attributed to aging or stress. Subtle problems with the executive functions of enhancement gene therapyplanningflexibility, and abstract thinkingor impairments in semantic memory memory of meanings, and concept relationships can also be symptomatic of the early stages of AD.

MCI can present with a variety of symptoms, and when memory loss is the predominant symptom, it is termed amnestic MCI and is frequently seen as a prodromal stage of Alzheimer's disease. In enhancmeent with AD, the increasing threapy of learning and memory eventually leads to a definitive diagnosis. In a small percentage, difficulties with language, executive functions, perception agnosiaor execution of movements apraxia are more prominent than memory problems.

Language problems are mainly characterised by a shrinking vocabulary and decreased word fluencyleading to a general impoverishment of oral and written language.

Progressive deterioration eventually hinders independence, with subjects being unable to perform most common activities of daily living. Reading and writing skills are also progressively lost. Behavioral and neuropsychiatric changes become more prevalent.

Common manifestations are wanderingirritability and emotional labilityleading to crying, outbursts of unpremeditated aggressionor resistance to caregiving. During the final stage, known as the late stage or severe stage, the patient is completely dependent upon caregivers. Although aggressiveness can still be present, extreme apathy and exhaustion are much more common symptoms. People with Alzheimer's disease will ultimately not be able to perform even the simplest tasks independently; muscle mass and mobility deteriorates to the point where they are bedridden and unable to feed themselves. The cause of death is usually an external factor, such as infection of pressure ulcers enhancement gene therapy pneumonianot the disease itself.

These types are known as early onset familial Alzheimer's diseasecan have a very early onset, and a faster rate of progression. Most cases of Alzheimer's are not inherited and are termed sporadic AD, in which environmental and genetic differences may act as risk factors.]
