- Aging--Learn to Enjoy the Inevitable, part I
-
-
- ------------------------------------------------------------------------------
-
- Robert Browning wrote: "Grow old along with me! The best is yet to be,
- The last of life, for which the first was made."
- In just a few words, he summarized the idea that old age isn't the dim,
- dark, painful, fearful thing so many people think it will be. Growing older
- can be a fulfilling time, an age when you know what you want out of life but
- haven't stopped going out and getting it; an age when you have fond
- recollections and time to make more happy memories.
- Unfortunately, the subject is so full of myths that many people fear
- aging. We live in a society that practices "ageism," a prejudice against
- people based on their age. Advertisements make us believe that only young
- people enjoy themselves and have energy or sexual feelings. Old people,
- according to commercials, are tired, feeble, confused, silly and prone to
- indigestion, constipation, denture stains, arthritis and bladder incontinence.
- Admittedly, there is a small grain of truth in these myths. Although
- aging isn't a disease, getting older does mean more aches and pains and other
- changes in your body. YOUR vision may weaken; your hearing may be less acute;
- YOUR knees and other joints may start aching; you may slow down a bit. Very
- few people age without one or two physical problems, but the good news is that
- very few people get all of them.
- First, remember that you're not alone. The percentage of the American
- population over 65 is increasing as more people live longer. At the turn of
- the century, only 4 percent of Americans lived past age 65. Now, more than 12
- percent of the population is older than that, and 40 years from now it will be
- more like 20 percent.
- It's important for you to understand the aging process, just as it was
- important for you to understand what was happening to your body when you went
- through puberty. Aging is inevitable. It's impossible to stop the flow of
- time and almost impossible to stop the effects of time's passage. But with a
- positive outlook, you can make Browning's words true for you: "The best is
- yet to be."
- It would be easy to define aging as the effects of a long life, but it
- isn't that simple. We all know of people like comedian George Burns, who is
- keeping a busy schedule of performances well into his 90's. Or producer
- George Abbott, who still works in the theater in his second century. Former
- congressman Hamilton Fish Sr. recently remarried, just a few months short of
- his 100th birthday. Yet, Rita Hayworth died of Alzheimer's disease at age 68.
- Why do some people get old so young, while others stay young so old? The
- answer is that we don't really know.
- Heredity is, to some extent, a factor. Someone once said that the best
- way to live a long healthy life is to pick parents who lived to healthy old
- ages. The trouble is, we don't get to pick our parents. While it's true that
- some of the infirmities of old age, such as impaired vision, hearing or
- arthritis, run in families, there is more to aging than your family tree.
- Different people age at different rates, but their problems will be similar.
- How well we take care of ourselves also can help us lead longer lives.
- People who smoke, are sedentary, eat and drink too much, generally don't live
- as long as people who keep their weight down, exercise regularly and don't
- smoke. Keeping active is the best advice on how to stay young. Activity
- helps both the mind and body. More people rust out than wear out.
- There is no simple explanation of aging, although there are several
- theories. These theories basically fall into two camps. One says that aging
- is related to how fast we live--that is, how fast our hearts beat, our lungs
- breathe and our metabolisms work--and that outside events, such as exposure to
- chemicals, accidents and plain wear and tear eventually wears us out. The
- other set of theories is based on the idea that aging and death are programmed
- into us and are an essential part of our lives, like growth and adolescence.
- These two groups of theories overlap a great deal, and both may be at least
- partly right.
- Both theories rest on the fact that throughout our lives our bodies
- reproduce and replace cells, the building blocks of human flesh. The genes,
- contained in a chemical called deoxyribonucleic acid, or DNA, in each cell's
- nucleus tell it how to create proteins and other chemicals and tell it when to
- split. Most cells in our bodies use the information in DNA to create
- replacements for themselves at regular intervals. Other cells, most notably
- nerve cells in the brain and nervous system, are meant to last a lifetime, and
- as they die off, they aren't replaced, although the remaining nerve cells do
- work harder.
- As we age, however, DNA is damaged through wear and tear, like a document
- copied too many times. Although the body can repair DNA--and does so
- regularly--it could be that the body slowly loses this ability and replacement
- cells aren't made as well as those created earlier in life.
- The chemicals, especially proteins, that receive faulty DNA instructions
- may be poorly made as well. A protein called collagen, which is an important
- component in skin and connective tissue, becomes less pliable with age and
- loses its ability to stretch and relax. Some researchers believe that
- unstable chemicals called free radicals, which are produced normally during
- metabolism, damage our bodies. This damage accumulates and eventually leads
- to the breakdown of individual cells and organs.
- On the other hand, other researchers believe that certain genes are
- switched off as we get older, in a predetermined pattern. They point out that
- different creatures have different life-spans that cannot be extended past a
- certain point. Mice live much shorter lives than people do, but parrots live
- longer.
- These researchers note that the maximum human life-span is probably in
- the range of 115-120 years. The oldest documented human life was 120 years,
- while longer life-spans for certain groups of people, notably those living in
- Soviet Georgia who are said to be in their 150's, are unsubstantiated.
- While either of these theories may be correct, the present fact is that
- more people are living to older ages than ever before. Research may not be
- able to extend our lives past a certain point, but it can help us improve the
- years we do have. The main goal of gerontology, the study of aging, is to let
- more of us age as well as we can with minimum disability.
- The problems that come with age follow certain patterns. As long as
- you're aging anyway--and we all will--it's best to understand as much about it
- as possible.
-
- The Senses
-
- One of the most frequently occurring disabilities of aging is sensory
- loss. Although people can lose portions of their vision, hearing, sense of
- taste or smell at any time during life, it commonly happens as we grow older.
- Partial loss of hearing and vision may occur with age due to lifelong
- activities--repeated exposure to loud noise can lead to hearing loss--or from
- certain disabilities.--diabetes can be a factor in certain types of vision
- problems.
-
- EYES
-
- Although many older people can read fine print and thread needles without
- glasses, others lose some vision as they age. Essentially, your eye is like a
- camera. Light comes in through the clear cornea in front, goes through the
- pupil and is focused by the lens, which is right behind the pupil. This
- focused picture is projected onto the retina that lines the back of the eye.
- The retina interprets the image into electrical messages sent to the brain by
- the optic nerve. If anything interferes with any of these steps, you can have
- impaired vision.
- You should have your eyes checked regularly by an ophthalmologist (a
- medical doctor who specializes in the eyes) or an optometrist (a nonmedical
- doctor who can examine eyes and fit you with glasses, but cannot treat medical
- diseases of the eye). If you have a family history of diabetes, have your
- eyes examined more frequently, since several eye conditions, notably
- cataracts, macular degeneration and retinal detachment, occur more frequently
- in diabetics.
- PRESBYOPIA: Probably the most common eye problem in older people,
- presbyopia is a problem of refraction, wherein it is difficult for the eye to
- focus on objects at nearer distances. A common symptom of presbyopia is
- holding a newspaper out at arms' length in an effort to focus on the print. In
- younger people, the lens of the eye is very flexible and can change shape
- slightly to bring objects at different distances into focus on the back of the
- eye, or retina. In presbyopia (which actually means aging eye), the lens
- loses some of its flexibility, and you may need glasses for close-up work such
- as reading or sewing. Presbyopia usually starts after age 40 and its
- treatment is simple: glasses.
- CATARACTS: A cataract is a clouding of the lens so that light doesn't
- pass though well. Instead of being like clear glass, a cataractous lens is
- like frosted glass. (The word cataract means "waterfall," because having a
- cataract on your lenses is comparable to seeing through a waterfall.)
- A cataract is neither a film over the eye, nor a growth within the eye.
- If the clouded area of your lens isn't in the center, but is off to one side,
- and isn't interfering with your vision, you can easily live with it. However,
- if a cataract keeps you from driving, reading or enjoying life the way you
- would like, consider having it removed. Surgery is the only way to treat
- cataracts and the whole lens is removed. No matter what you've heard, lasers
- cannot be used to treat cataracts, although they may be used during the
- surgical procedure or several months after surgery, if a complication sets in.
- For most people, cataract surgery is simple and is done on an outpatient
- basis. You go to the hospital, have the procedure done and go home the same
- day. There is little discomfort. Most people who have a cataract removed
- have a small plastic artificial lens (called an intraocular lens) implanted
- during the surgery. If an artificial lens isn't implanted, you will need
- special glasses or contact lenses after your surgery. Most people who develop
- a cataract that interferes with vision in one eye will develop one in the
- other eye. If you need cataract surgery in both eyes, the procedures will be
- scheduled a few weeks or months apart.
- GLAUCOMA: Two out of every 100 people over 35 years of age develop
- glaucoma, a serious eye condition. Glaucoma is a disease where the internal
- pressure of the eye increases, and if it isn't treated, can result in
- blindness. Part of the problem is that glaucoma has almost no symptoms. There
- is no pain and, frequently, the first symptom is a partial loss of vision.
- Normally, a fluid called aqueous humor flows from the back part of the
- eye, around the lens and into the front part of the eye and then back through
- a special drainage system around the edge of the iris. In glaucoma, this
- drainage system is partially or totally blocked, which means the pressure
- increases within the eye, leading eventually to damage to the optic nerve. The
- faults in the drainage system that cause the problem may be due to a
- congenital condition, to injury, to something clogging the system, or most
- commonly, to the narrowing of elements of the drainage system.
- Glaucoma is most commonly treated with prescription eye drops. These
- dilate the drainage system and allow the pressure to decrease. The eye drops
- do have some side effects, such as headaches or temporarily blurred vision. If
- your glaucoma progresses in spite of the medications, there are surgical
- procedures that your doctor may recommend, as well as laser treatments that
- may reopen the drainage system. Still, the first line of treatment is eye
- drops.
- MACULAR DEGENERATION AND RETINAL DETACHMENT: While problems such as
- presbyopia and cataracts are caused at the front of the eye, macular
- degeneration and retinal detachment are problems occurring with the back of
- the eye. The retina is a thin film lining at the back of the eve that
- receives images. The macula is the central area of the retina where the lens
- focuses the central part of an image. When you are looking at this page of
- print, the word you are reading now and a small area around it is being
- focused on your macula, while the rest of the page is hitting the rest of
- your retina.
- About 70 percent of cases of macular degeneration are caused by aging,
- with the rest caused by disease, infection or accident. In macular
- degeneration, when the macula breaks down, your central vision becomes blurry.
- If you are looking at a page of print, the edges of the page are clear, but
- the center is fuzzy, missing completely as if something were blocking your
- view, or distorted and wavy. If only one eye is affected, you may not even
- notice you have a problem, but if both maculas degenerate, you may have a
- great deal of difficulty in reading or doing close-up work.
- A good eye examination will detect macular degeneration early. However,
- for the type of macular degeneration that occurs with age, there is little
- that can be done. Ophthalmologists are using lasers to help stop the spread
- of macular degeneration that is caused by disease, but this treatment does not
- help the more common age-induced macular degeneration.
- Retinal detachment occurs when the entire retina, or parts of it, comes
- lose from the back of the eye. Retinal detachment can happen quite suddenly.
- Vision can be suddenly clouded or completely lost. If this happens, see your
- doctor or go to an emergency room immediately. There are ways to reattach a
- detached retina either with surgery or using a laser. These procedures can
- return some or most of your vision.
- Most people experience tiny black spots or specks that float through
- their vision. Commonly called floaters, these are usually harmless and most
- people learn to ignore them. If, however, you notice a sudden increase in
- their number, or if they are accompanied by flashes of light, an examination
- is in order, since this could be a sign of retinal detachment.
- LOW VISION AIDS: If you should experience some loss of vision, don't
- despair; there are several ways for you to cope and continue to live
- independently. Your ophthalmologist or optometrist can fit you with special
- glasses that will make the most of what vision you have. He or she will also
- refer you to therapists who can train you to use optical aids. These include
- special hand-held lenses, prisms or mirrors, and even televisions and
- computers that magnify the picture.
- Other helpful aids include large-print books and magazines, needle
- threaders, and even telephones and calculators with larger, easier to see
- characters on them. Many magazines are printed in large type, and local
- libraries often have a selection of large-print books. Many books are now
- widely available on audio tape for listening, which can be a great joy for
- someone who no longer can read easily.
-
- EARS
-
- Hearing loss is something many older people refuse to acknowledge, yet it
- is one of the most common results of aging. About 30 percent of all people
- between the ages of 65 and 74 have some degree of hearing loss and that
- percentage increases to 50 percent of all those over age 75. Refusal to admit
- that you have lost some hearing can limit your social life, frustrate your
- ability to communicate and be downright dangerous if you aren't able to hear
- something like a fire alarm. You may also become depressed and unresponsive.
- Unfortunately, hearing loss in the elderly can be misdiagnosed as mental
- confusion.
- Aging can affect hearing in several ways. Normally, your outer ear,
- collects sound and channels it into the ear canal to the car drum. The ear
- drum vibrates when the sound hits it and three tiny bones in the middle ear
- conduct the sound into the cochlea, in the inner ear, where it vibrates tiny
- hairs that translate the sound into nerve impulses that go to the brain.
- Anything affecting how sound goes from the outer ear through to the tiny
- bones--a middle ear infection, wax buildup, a punctured eardrum--is called a
- conductive hearing loss. There are several medical or surgical ways to treat
- and reverse a conductive hearing loss.
- If the problem is in the cochlea, it is a sensorineural hearing loss, and
- this is where most problems caused by age occur. The bad news is that there
- aren't too many ways of treating this kind of hearing loss, which is also
- called nerve deafness. When nerve deafness is caused by aging, it is called
- presbycusis. Essentially, in nerve deafness, the tiny hairs of the cochlea
- have started to deteriorate and the body cannot regenerate them. These tiny
- cells are also damaged or destroyed by prolonged exposure to loud noise, such
- as years of working with a jackhammer or living near an airport.
- There are several warning signs to look for if you think you are losing
- your hearing. Do people around you seem to be mumbling? Do you have trouble
- understanding spoken words or a telephone conversation? Do you hear a ringing
- or hissing sound continually? Does your family tell you that you play the
- radio or television ton loudly? Do you not hear common household sounds such
- as a faucet dripping or your doorbell? These are all symptoms of hearing loss
- and you should take them seriously.
- You can learn to cope with your loss of hearing first by acknowledging
- it. Let people know that you don't hear well and if you don't understand what
- they have said, ask them to repeat it. Many people who have lost some hearing
- get into the habit of nodding while listening, even if they haven't caught all
- of the conversation. This is a bad habit, because it gives the speaker the
- impression that you understood what they said.
- HEARING AIDS: Hearing aids can help many people who have suffered some
- hearing loss. They won't make you hear perfectly, but they can help. Don't
- be ashamed to get a hearing aid. No one is ashamed to get glasses, so think
- of them as glasses for your ears. Remember also that you may have to try out
- one or two hearing aids before you get one that suits you.
- There are basically five kinds of hearing aids, ranging from tiny ones
- that fit completely into the ear canal to large ones for severe hearing loss
- that are worn in a shirt pocket. All hearing aids consist of a microphone to
- pick up sounds, an amplifier to make the sound louder, a miniature receiver to
- deliver the louder sound into the ear, and batteries to power the whole thing.
- The size and type of hearing aid you get depends on how severe your hearing
- loss is, what kind of hearing loss you have and what type of hearing aid you
- can handle easily.
- In addition to assistive devices, consider buying a caption decoder for
- your television, which puts dialogue in print at the bottom of the screen.
- Many live and taped television shows are closed-captioned and this device can
- increase your viewing pleasure.
- TINNITUS: Tinnitus is a ringing in the ears, when your ears are hearing
- sounds that don't really exist. Ringing in the ear can be perceived as a
- constant hum, a buzz or a ringing sound that can be intermittent or constant.
- This can be one symptom of hearing loss, or it can occur in people who
- otherwise hear normally.
- If you suffer from tinnitus, have your cars and your hearing checked. In
- some cases, the apparent noise is caused by a wax plug in the car canal, a
- buildup of fluid in the middle car, high or low blood pressure, or a hole in
- the ear drum. These conditions can be taken care of and your tinnitus may be
- relieved. Tinnitus may also be a side effect of taking aspirin, but this
- usually occurs only when high doses are needed to treat arthritis pain.
- The most common cause of tinnitus is damage to the auditory nerve itself
- and this cannot be cured. Nerve damage that leads to tinnitus in the elderly
- is often due to aging, but it can be aggravated by constant exposure to loud
- noise.
- Even though your tinnitus may be untreatable, you can learn to cope with
- it. Because the hissing and ringing seem worse when you are in a quiet place,
- playing a radio softly in the background helps mask the noise. For some
- people, getting a hearing aid helps their tinnitus, although why this works is
- unknown.
-
- TASTE AND SMELL
-
- Many older people lose a portion of their ability to taste and smell.
- Although such a loss isn't as disabling as the loss of vision or hearing, it
- can interfere with eating and enjoyment of your surroundings. The loss of
- taste or smell, which often go hand in hand, may show up first as a lack of
- interest in food. Nothing may taste right; everything but highly seasoned
- food may taste bland. This could lead to a loss of appetite and eventual
- malnutrition.
- If you suspect you have lost part of your sense of taste or smell, see
- your physician for a complete physical. There are some reversible causes for
- these sensory losses, including medications to clear up sinus infections and
- head colds.
-
- The Nervous System
-
- Perhaps one of the greatest fears that people have about growing older is
- senility, the loss of one's mental capabilities with the passage of years.
- This fear is unfounded. Senility isn't an inevitable part of growing older.
- Indeed, people don't lose their power to think and remember without a physical
- reason, which is why senility is really a bad word. A better word is dementia
- ("deprived of mind"), which is a blanket term for any impairment of
- intellectual function.
- Meanwhile, we're learning more about Alzheimer's disease and
- multi-infarct dementia, two conditions that cause the loss of mental function
- and for which there are few treatments. Many people who are diagnosed as
- being senile are actually suffering from overmedication or poor medication
- combinations, depression, undetected hearing loss, hypothermia, drug or
- alcohol abuse, or any of several conditions that can be treated. Many cases
- of dementia can be reversed once their cause is properly diagnosed.
-
- ALZHEIMER'S DISEASE
-
- Perhaps there is no disease as merciless as Alzheimer's. A person in the
- final stages of Alzheimer's loses his or her memory and personality. The
- family must cope with the gradual fading away of their loved one while the
- body still lives. It is estimated that between 2.5 million and 3 million
- Americans have this disease, which means as many as one in 10 of all people
- over 65 years old.
- Alzheimer's causes a variety of physical, psychological and emotional
- changes. It can start as mild forgetfulness and episodes of confusion. Often,
- affected people will suddenly not know how to do something they have done all
- their lives, such as read music or find the way to a local store. If
- Alzheimer's, or any other dementia, is suspected, the patient should undergo a
- complete physical and psychological examination to rule out any other
- problems.
- Alzheimer's is a disease that causes changes within the brain. When bits
- of brain tissue from an Alzheimer's patient are examined under the microscope,
- researchers can see dead nerve cells and tangles of nerve fibers and plaques
- in greater amounts than in healthy older brain tissue. Unfortunately, no
- physician can be certain of the diagnosis of this disease until after the
- patient has died and this brain tissue can be examined. Generally, people
- with severe effects of the disease show more plaques and tangles in their
- brain tissue.
- The cause of Alzheimer's disease is still uncertain. It does tend to run
- in families, and there is evidence of a genetic link. Some evidence points to
- an infectious agent, such as a slow virus that takes many years to develop.
- There is no cure for Alzheimer's. Treatment consists of keeping the
- patient as comfortable as possible. Medications can be used to keep the
- patient from becoming agitated or anxious. The progress of Alzheimer's can be
- slowed by keeping the patient stimulated and active, so that the patient is
- using as much of the brain as possible. Overprotection actually may provoke
- babylike behavior.
- Until the disease is advanced and the patient is institutionalized, the
- burden of caring for an Alzheimer's patient can be a great emotional and
- physical strain on the family. There are self-help groups and home-nursing
- services that can help the family cope. Some social service agencies run
- programs where groups of Alzheimer's patients meet to exercise, undergo some
- training, and socialize--which gives them stimulation and their family members
- a needed "day off."
-
- MULTI-INFARCT DEMENTIA
-
- After Alzheimer's disease, the second leading cause of dementia in the
- elderly is due to problems with the circulation of blood to the brain. The
- brain needs a constant flow of oxygenated blood. Any interruption in that
- blood flow can cause parts of the brain to infarct or die from lack of oxygen.
- This interruption may be caused by a blood clot or a burst blood vessel,
- creating a stroke.
- If the affected blood vessel is a major one, the effects can be sudden
- and dramatic, even mortal. Small strokes, on the other hand, frequently occur
- and leave milder symptoms, such as slurring of words or numbness in a hand. If
- a series of small strokes occur, the chances are great that the person will
- lose some intellectual capability and decline physically.
- Multi-infarct dementia accounts for between 12 percent and 20 percent of
- all cases of dementia in the elderly. A combination of Alzheimer's and
- multi-farct dementia causes an estimated 20 percent of all cases of dementia
- in people over age 65. Patients with multi-infarct dementia usually have a
- history of cardiovascular disease, such as high blood pressure.
- Alzheimer's and multi-infarct dementia are different in the way they
- progress. Alzheimer's progresses gradually, but steadily. A patient with
- multi-infarct dementia loses mental function only with each new infarct, and
- so there is a loss of function followed by a period of stability, until
- suddenly another loss of function occurs. Frequently, the infarcts will occur
- in the same area of the brain, so a patient may eventually lose the ability to
- move one side of the body or communications skills. As with Alzheimer's
- disease, the patient should be kept as stimulated as possible.
