Alzheimer's disease relate to aging - Research Paper Example This document examines the prevalence of Alzheimer’s among the elderly persons and the resources available in Marshall County for helping the victims of the condition. As persons advance in age, the body undergoes various changes in their brains and results to dementias (UCSF Memory and Aging Center, 2014). For example, the brain shrinks that occur in the prefrontal cortex and hippocampus. The shrinking of the brain interferes with memory, learning, planning, etc. The changes in neurons and neurotransmitters can degrade the white matter and result to reduction in communication (UCSF Memory and Aging Center, 2014). In some instances, plagues and tangles structures develops outside and inside of the neurons respectively thus causing the brain cells to stop working and eventually die thus causing failure of memory, change in characters and complications with carry out day to day activities (Swaab et al., 2011). Also, changes in blood vessels occur with age, resulting to reduced blood flow due to narrowing of the arteries and less growth of new capillaries. With age, there is an increase in brain inflammation and increase in damages caused by free rad icals that interfere with normal functioning of the brain (Swaab et al., 2011). The changes in brain that occurs with age are the most likely cause of Alzheimer’s among the elderly persons. The most notable change in brain with age is atrophy or the shrinking of some parts of the brain, the secretion on wobbly molecules known as free radicals, the brain inflammation and dysfunction of the mitochondrial resulting to collapse of generation of energy within the cells (Swaab et al., 2011). Various studies have established that five percent of persons with Alzheimer’s occur due to inherited factors from the parents. An example is the familial Alzheimer’s disorder caused by alterations occurring in one of the inheritable genes in human

To what extent does social role theory explain anti-social behaviour Essay

To what extent does social role theory explain anti-social behaviour - Essay Example Whether the interaction is going to be positive or not depends on the nature of the people interacting with each other. The increasingly diverse and complex social roles that human being plays lead to socialization and personality development (Newman 70). Social Role theory studies the development of human being through different roles that he plays. According to Briddle (1979) and Brown (1965), â€Å"a social role is any set of behaviors that has a socially agreed-upon function and accepted code of norms† (Newman 70). However, when the social norms and functions become distorted with negative attitudes of prejudice, discrimination and racism, then people who are the victim of it become frustrated and their frustration leads to anti-social behavior. The word ‘role’ in social role theory is taken from the context of theatre where the actor behaves and acts as expected from him through the script (Newman 70). The same concept is applied to social life. The social life works as a stage, the social identities that person assumes work as roles and the behavior expectation from each role that people play act as script (Newman 70). With every step in life, the range and the nature of role changes and people learn to adjust and accommodate the new things and behavior pattern that come with it (Newman 70). However, there are times when the this adjustment becomes difficult and people start finding it impossible to fit into the social scenarios. Mostly, the problem begins when a person gets into an adolescence phase and begin to develop a social identity. Social identity is formed when a person interacts with people in personal relationship and in social groups(Newman 72). According to Tajfel
