The agedness Special Senses Thursday, November 17, 2011 1. ) Age-related Macular Disease Is a disease associated with aging that gradually destroys sharp, exchange hatful. Central vision is needed for seeing objects clearly and for common mundane tasks such as reading and driving. AMD affects the macula, the part of the eye that allows you to see comely detail. There are two forms of age-related macular degeneration Dry form and slopped form. The dry form is characterized by the presence of yellow deposits, called drusen, in the macula.A fewer drusen whitethorn not cause change in vision however, as they grow in size and increase in number, they may lead to a dimming or distortion of vision that people name most noticeable when they read. In more advanced stages, there is likewise a thinning of the light-sensitive layer of cells in the macula tether to atrophy, or tissue death. In the atrophic form, pati ents may have guile spots in the center of their vision. The wet form is characterized by the harvest- meter of ab mean(prenominal) occupation vessels from the choroid underneath the macula.These blood vessels leak blood and fluid into the retina, causing distortion of vision that breaks straight lines look wavy, as well as blind spots and pass of telephone exchange vision. They last scar, leading to permanent loss of central vision. They affect quotidian life story in that there is struggle to do housework, studying, shopping, enjoying leisure activities and interests such as reading. 2. ) Glaucoma Is a disease in which distress to the optic nerve leads to progressive, irreversible vision loss because the aqueous humor does not flow come on of the eye properly and fluid pressure builds up over time causing damage to the optic nerve.It is the second leading cause of blindness. It affects stars periodical life such as driving or playing certain sports . It causes contra st sensitivity, problems with glare, and light sensitivity which interfere with day-after-day activities. 3. ) Cataracts Are cloudy areas in the lens inside the eye which is normally clear. There are two types Age related cataracts which appear by and by in life and congenital cataracts, that may be present when a baby is born or shortly after birth. Cataracts cause an soul to see halos around lights. In some, the glare from car ights become techy and driving at night may be dangerous. Although far freshet is affected more than near vision. If the cataracts are bad enough, it cigarette make reading more difficult as well. 4. ) Detached Retina Is a derangement of the eye in which the retina peels away from its underlying layer of support tissue. initial detachment may be localized, but without rapid treatment the blameless retina may detach, leading to vision loss and blindness. It affects daily activities because of the sudden visual aspect of floaters, (dark, semi-transp arent, floating shapes) in the field of vision or a consume of black dots. These are actually red blood cells because all retinene tears bleed a little when they occur. ) It causes a loss of central vision, a loss of peripheral vision called the curtain effect and brief, beamy flashes of light which may be most noticeable when you move your look in the dark. 5. ) Deafness (sensorineural and conductive) Sensorineural earshot loss is due to damage to the pathway that weighed down impulses take from the hair cells of the inner ear to the auditive nerve and the brain. Conductive hearing loss is caused by anything that interferes with the transmission of sound from the outer to the inner ear.Both of these hearing losses affect daily life because you may own problem localizing sounds or understanding lyric in busy environments and participating in everyday normal conversations which can lead to social isolation, frustration, tension, anger, stress and depression. 6. ) Menieres Di sease Is a derangement of the inner ear that can affect hearing and balance to a varying degree. It is characterized by episodes of vertigo and tinnitus and progressive hearing loss, though usually in one ear. It affects daily life because for some, sounds appear tiny or distorted and may experience unusual sensitivity to noises.In addition, you may experience a sensation of fullness or pressure in one or both ears and unilateral or bilateral tinnitus. some(a) may have parasitic symptoms, which arent necessarily symptoms of Menieres, but sooner side effects from other symptoms. Typically these are nausea, vomiting and sweating. 7. ) motor ataxia Is an inability to coordinate muscle activity during voluntary movement, most frequently results from disorders of the cerebellum or the posterior columns of the spinal cord may involve the limbs, dot or trunk. Affects ones daily life because it can depart a persons walking pattern. For e. . wide based fluctuating gain with difficult y stopping, turning and problem walking in indisposed lit areas. It can cause falls due to postural instability, difficulty with tasks requiring fine control and coordination, tremors during voluntary movement, slurred speech and altered handwriting. 8. ) Hyposomnia literally means less sleep. It is a condition whereby a person does not need as much sleep as a normal individual. Specifically, they sleep less than 6 hours per night, but are adequately rested. It may occur at the onset, during or at the termination of sleep, and is common among the elderly.It affects daily life because the person that sleeps less but feels they need more experience the same problems as the person with insomnia that cannot sleep more than a few hours but feel they need more. It affects everyday life and activities because it is usually come with by general emotional upset, depression, or anxiety.
