Asthma is a chronic inflammatory disease of the airways, characterized by airway obstruction and increased airway responsiveness to different stimuli. The obstruction is reversible, either spontaneously or in response to treatment. The increase in airway responsiveness may be evident with specific stimuli like cat antigens, ragweed, or dust mites, or with non-specific stimuli like irritants, smoke, odors, infections, methacholine and histamine.
Prevalence of asthma among the elderly resembles the prevalence in the general population, at 5-7 percent. Many of them develop asthma symptoms for the first time at the age of 60 or 70 years, while there are others who age with asthma.
Asthma is not just a childhood disease; it can occur at any age. The classic symptoms of asthma — coughing, wheezing, breathlessness and tightness of chest — can easily be misinterpreted as part of normal ageing or be misdiagnosed as other health problems in older adults. Older people may not report their symptoms; may attribute their symptoms to another illness or disease or normal ageing; or may simply ignore their symptoms. Here are some of the most common reasons for unrecognized asthma in older people.
·Heart or lung diseases with similar symptoms to asthma, such as wheezing, can mask the presence of asthma.
·The actual symptoms of asthma might be dismissed as other conditions. For example, a chronic cough might be mistaken for bronchitis, or the inability to sleep during the night may be dismissed as insomnia.
Conditions which have symptoms in common with asthma in the elderly include:
§ Chronic obstructive pulmonary disease (COPD);
§ Chronic bronchitis, emphysema, or acute respiratory illness;
§ Rhinosinusitis with postnasal drip;
§ Gastro-oesophageal reflux; and
§ Cardiac diseases such as congestive heart failure, acute myocardial infarction (heart attack) or cardiac arrhythmia (abnormal heart rhythm).
Triggers for asthma attacks can differ in older adults with asthma from those most commonly affecting children with asthma. In older adults, viral respiratory illnesses (for example, colds and ‘flu), and airborne allergens are the most common triggers. This is why it’s important that older adults have an influenza vaccination every year. Pneumococcal vaccine is also recommended for all people who are over 65.
Some medications used frequently in older adults are also known to trigger asthma or make symptoms worse. Examples include: aspirin and other anti-inflammatory medications used to treat arthritis and other pain; beta-blockers used to treat hypertension (high blood pressure) and heart disease; and beta-blocking eye drops used to treat glaucoma. For this reason, it is important to keep a list of all the medications you currently use and show it to your doctor at each visit.
In addition to the issues above, changes in lung structure and function brought about by normal ageing may make the problems associated with asthma worse in the elderly.
Also, normal, age-related changes in the body mean that older people with asthma are more susceptible to adverse effects from the very medications they are taking to control their asthma. They may also be at risk of adverse interactions between different medications they are taking.
Remembering to take medications for chronic conditions, such as asthma, may be more of a challenge for older people than younger ones. Also, problems with co-ordination or arthritis of the hands may make using puffers and other asthma medication delivery devices difficult, and problems with eyesight may affect ability to read labels. If you have problems coordinating drug release and inhalation, you may find it easier using the puffer in conjunction with a spacer. Alternatively, you may be better off using a breath-activated device such as an Accuhaler, Autohaler or Turbuhaler.
· Have you experienced an attack or recurrent attacks of wheezing?
· Have you had a troublesome cough or wheeze on waking up in the morning?
· Do you have a tendency to cough or wheeze after exercising?
· Do you experience a cough, wheeze or chest tightness after exposure to airborne allergens or pollutants?
· Do colds go to your chest or take more than 10 days to clear up?
If asthma is suspected, see your doctor who will make a diagnosis and prescribe the appropriate treatment. Making the diagnosis will probably involve doing some basic lung function tests, performed before and after using an asthma reliever medicine. Many doctors have such testing equipment in their surgeries and it can be done by them or their practice nurses. They may also order a chest X-ray to rule out other disorders or to diagnose co-existing conditions.
You should also follow the same recommended general rules for the control of asthma that all people with asthma are encouraged to follow;these will be incorporated in the written asthma action plan that you develop with your doctor.
A Urinary Tract Infection May Cause an Older Person to be Confused
Urinary tract infections, with or without symptoms, are quite common in the elderly.
Asymptomatic (without symptom) UTIs in the elderly are usually not treated unless the benefits outweigh the risks, but recognizing and properly treating a symptomatic UTI in an elderly person may help prevent more serious infections and complications.
Prevention is the best and safest approach.
Is sudden confusion permanent? The answer to that may depend on whether or not and how quickly a cause is determined. Caregivers of the elderly should be particularly watchful for changes in an elder’s mental status and should contact a healthcare provider of any acute confusion or sudden worsening of existing confusion. Ruling out a UTI would be an appropriate early step if an elder suddenly became confused or had worsening confusion. Early treatment of a symptomatic UTI may prevent more serious symptoms and complications and can quite possibly result in a return to the elder’s normal mental status.Source:http://seniors-health-medicare.suite101.com/uti_may_be_cause_of_sudden_confusion_in_elderly
