In October 2014, a study showed that stem cells could help people with macular degeneration, which is a disease that causes continuous loss of sight. Researchers followed eighteen patients for three years and saw no signals of rejection of the transplanted stem cells (Young). Stem cells can also be used to create brain tissue

Introduction It is well established that the aging process adversely affects a number of neurocognitive functions. Increasing our understanding of the neurocognitive aging process remains a significant public health issue. A large body of cross-sectional data (Anstey, Lord, & Williams, 1997; Anstey, Luszcz, & Sanchez, 2001a; Anstey & Smith, 1999; Baltes & Lindenberger, 1997, 1997; Lin et al., 2011; Lindenberger & Baltes, 1994; Salthouse, Hancock, Meinz, & Hambrick, 1996) and longitudinal data (Anstey

Another milestone in science has been reached: the discovery of stem cells in the 19th Century. Stem cells have the ability to divide for indefinite periods in culture and to give rise to specialized cells (U.S. Department of Health and Human Services, 2009).

This can be caused from any sort of retinal degenerative disease like macular degeneration. This is when the front-end cells die, the photoreceptors die, and over time, all the cells and the circuits that are connected to them, they die too. Until the only things that you have left are these cells here, the output cells, the

As population ages in all developing nations, impacts of falls remaining a huge problem for social and healthcare systems (Oliver, 2009). According to National Institute on Aging (NIA), in 2006 almost 500 million people worldwide were aged 65 or older. That number projected to reach 1 billion by 2030 with most rapid increases in developing countries.

Alzheimer’s disease is a neurodegenerative disorder, meaning it attacks the neurons within the brain. Neurons are the areas of the brain that allow for chemical messages, or neurotransmitters, to be transmitted. These neurons are necessary for connections with other nerve cells, and without them, the neuronS ultimately die. Alzheimer’s is a form of, and the most common cause of, dementia, or loss of intellectual capacity and personality. ("Dementia.") Alzheimer’s disease, or AD, is not a normal part
