Drug treatment for allergies and early identification of Alzheimer's disease
Use of medication
If the above preventative measures do not completely resolve the issue, allergy medications may be helpful for the patient. Here are some applicable medications.
Dr. Norman, an expert on antihistamines, points out: "The first line of defense against pollen allergies is the antihistamine."
These medications are available at pharmacies or prescribed by a doctor. When your body encounters an allergen, antihistamines work by preventing histamine from disrupting your body's response. In the past, antihistamines primarily kept you calm and sluggish; now, pharmaceutical companies have developed antihistamines with non-sedating effects, thus preventing drowsiness. Here's an important tip: take your antihistamines before your allergy becomes severe.
Oral decongestants have some adverse side effects, such as insomnia and high blood pressure, so you need to do a drug trial before using them to see how they affect you.
Immunotherapy, which involves a series of gradually increasing doses of allergen injections, is a last resort for treating allergies. While immunotherapy is ineffective for food allergies, research suggests it can be effective in treating allergies caused by dust, bee venom, cat dander, ragweed, and grass.
Dr. Adkinson points out, "When active avoidance and medication fail, and the patient's allergic reaction has lasted for more than a season, we usually consider immunotherapy."
However, be prepared, as immunotherapy lasts for a long time. During the first 8-16 weeks of the first year, administer injections 1-2 times per week, then once a week during the following periods of the year, and thereafter, it is recommended to administer injections every 2-3 weeks.
Even while undergoing immunotherapy, you need to take your medication regularly and avoid allergens.
Fun Facts
Dust Analysis
How bad are the allergens in your home?
Currently, you can obtain relatively accurate statistics on common allergens circulating in your home. Researchers at Johns Hopkins University in Baltimore can analyze dust allergens in your home's air and then provide you with precise measurements of allergen levels.
If you're interested, you can learn how to analyze this process. It's actually quite simple: connect a small collection device to your vacuum cleaner, and the collected dust sample can be analyzed in a lab to tell you the types and concentrations of allergens in your home.
Dr. Robert Hamilton, Associate Professor of Medicine at Johns Hopkins University, points out: "This analysis allows you to make a basic assessment of your indoor environment so you can see if there are any dust allergy issues. So based on that, you can decide whether to clean more diligently or not to worry." Currently, this dust analysis costs $25.
Alzheimer's disease
Timely treatment
You see signs of aging in an elderly friend, but for a long time you're unsure what's wrong. This friend first forgets simple things, like the names of close friends or jokes and witty remarks they used to know. Then they begin to forget entire conversations-or even whether they were ever discussed at all. Later, everyday tasks like shopping and keeping accounts become increasingly difficult. Finally, you realize that the friend you once knew is long gone-taking with him his humor, his charm, and his boundless understanding.
The cause of this outcome is Alzheimer's disease, whose most terrifying symptom is the gradual loss of memory and the inability to collect and retain information. Ultimately, patients are trapped in a permanent reality, inevitably leading to death. Alzheimer's disease is currently the fourth leading cause of death among adult Americans. It has been called the disease of the century, a silent and mysterious "plague."
If you are under 60, Alzheimer's disease is not a near-term threat. Since there's nothing you can do to prevent it, you don't need to worry about it too much. However, given that others in your life have already developed the disease, and that you will also grow old with it, it's wise to pay attention to research in this medical field.
Self-decay
Experts believe that Alzheimer's disease not only damages memory but also the brain. Microscopic examination reveals abnormal deposits called plaques on the surface of the brains of Alzheimer's patients, which have infiltrated normal brain cells. Leon So, chair of the Department of Neuroscience at the University of California, San Diego, explains that long-term plaque buildup can cause the death of nerve cells. Since nerve cells are the brain cells that transmit and process information, their loss will impair brain function and even lead to paralysis.
Experts are still unsure what causes Alzheimer's disease. One suspicion is beta-amyloid protein, which is a fragment of protein with distorted shape that can accumulate in brain cells and create cavities. Another theory suggests that excessive aluminum intake and insufficient zinc intake can contribute to Alzheimer's. However, experts believe it is becoming increasingly clear that Alzheimer's disease may be caused by many factors, and there is more than one underlying cause.
It's not just memory loss
Constantly losing keys, forgetting where I parked my car, and not remembering my colleagues' names-is this dementia?
I'm afraid not. It's worth noting that Alzheimer's patients don't suspect anything wrong with their forgetfulness. Dr. So points out, "If you suspect you have Alzheimer's, it's very likely you don't actually have the disease."
Furthermore, while Alzheimer's disease is becoming increasingly common, it is not a normal consequence of aging. On the contrary, a certain degree of memory loss is an inevitable result of human aging. Victor Henderson, professor of neurology, geriatrics, and psychology at the University of Southern California, Los Angeles, points out: "Everyone forgets things; as we get older, we realize our memory is failing."
Latest Information
• Prevalence: The threat of Alzheimer's disease is gradually increasing. It is estimated that 10% of Americans aged 75 to 85 have the disease, and the probability of developing Alzheimer's disease is as high as 50% for those over 85. It is estimated that Alzheimer's disease causes approximately 100,000 deaths each year.
• Risk factors: The causes of the disease are mostly unknown. Some evidence suggests that family and educational circumstances determine the onset of the disease; people with little education and limited career achievements are more prone to Alzheimer's disease. In addition, excessive aluminum intake or insufficient zinc intake may also play a role in the onset of the disease.
• Affected age group: mainly the elderly; the older a person is, the more susceptible they are to the disease.
• Gender differences: Same for both men and women.
• Target patients: Family doctors can make early diagnoses, but it is recommended to seek treatment from specialists in neurology or geriatrics.
Therefore, if you start forgetting "normal" things, like where you put your keys, you don't need to worry, as this is normal. However, if the "memory loss" involves entire conversations or even experiences from several days ago, then you should see a doctor. Although sometimes men as young as 40 can develop this condition, which doctors call premature aging dementia, it generally affects older adults. Dr. Henderson points out, "This condition is very common among older adults; 50% of people over 85 will have it."
Doctors point out that evidence suggests Alzheimer's disease is related to family circumstances, with those less educated or less successful in their careers being more susceptible. Experts are unsure why this is the case; one possibility is that the more you use your brain, the better you maintain it; another possibility is that well-educated and successful individuals may develop strategies to manage Alzheimer's effectively, thus delaying diagnosis.
Timely diagnosis
Accurate diagnosis is always crucial, especially when Alzheimer's disease is suspected. This is because other treatable conditions, such as mini-strokes, nutritional deficiencies, and pernicious anemia, can produce symptoms similar to Alzheimer's.
Autopsy is the only method with a 100% accurate diagnosis of Alzheimer's disease. However, doctors can arrive at a near-perfect diagnosis through brain scans, interviews with the patient's family, psychological assessments, and other laboratory tests. Furthermore, researchers at Harvard University have developed a simple eye test: after instilling pupil-dilating drops into the eyes, the pupils of Alzheimer's patients dilate more than those of normal individuals. This method has been used to detect several cases of Alzheimer's disease.
Early diagnosis can not only alleviate the anxiety of patients and their families, but also give patients the opportunity to participate in experimental treatments, which may slow down or minimize the onset of symptoms in Alzheimer's patients.
