Is there a correlation between aluminum and Alzheimer's? Does coffee drinking increase the risk of developing Alzheimer’s disease? [ 08/30/13 ]
There is some evidence to causally link aluminum to Alzheimer's disease, however, further studies need to be done to definitely establish that high levels of dietary aluminum lead to Alzheimer's disease. You can read more about the connection between aluminum and AD in the frequently asked questions (FAQs) section of our website.
As far as coffee goes, recent studies indicate that there may be a beneficial effect to consuming caffeine. For example, in one study it was found that the prevalence of Alzheimer's disease and dementia was lower in people who consume on average one cup of coffee per day compared to those who do not regularly drink coffee. Another study investigated the effects of caffeine in a mouse model of Alzheimer's disease (Arendash et al. Neuroscience. 2006; 142(4): 941-952). Researchers found that giving the mice 1.5 mg of caffeine per day in their drinking water (which is the human equivalent of about five cups of coffee per day) caused the mice to perform significantly better on several behavioral and cognitive tests than their non-caffeine consuming counterparts. Additionally, the investigators found that long-term administration of caffeine to these transgenic mice resulted in lower brain levels of amyloid beta protein, which is the protein responsible for much of the pathology (e.g., amyloid plaques) characteristic of Alzheimer's disease. However, because of the negative side effects associated with the overuse of caffeine (heart palpitations, anxiety, nervousness, headaches, peptic ulcers, etc.) it generally not advised that anyone should start drastically increasing their coffee intake.
I read that a neurologist has special tests that can determine if uncharacteristic behavior is due to dementia or some other condition. My husband's neurologist diagnosed my husband with Alzheimer’s disease; however, he did not give him any tests. Are there tests that are routinely given as part of an Alzheimer’s disease evaluation? [ 08/30/13 ]
Physicians can correctly diagnose Alzheimer's disease (AD) about 90 percent of the time based on mental and behavioral symptoms, a physical examination, neuropsychological tests, and laboratory tests. It is possible that your husband's symptoms were so pronounced (to the trained eye) that the neurologist felt confident in declaring an AD diagnosis without further testing. To learn more about the tests that are routinely performed as part of an Alzheimer's disease evaluation, please read the section titled “What are the diagnostic tests used in Alzheimer's disease?” under Frequently Asked Questions (FAQ).
My mother had been suffering from Alzheimer disease for six years. She started taking Exelon; then her doctor changed the medication to Aricept (donepezil), and finally Reminyl (galantamine) in combination with Ebixa (memantine). In addition to these drugs, she takes heart medicines, including Furosemide, Lanoxin, and Levothyroxine. Unfortunately, she died six month ago as a result of her ascites. In my opinion, the ascites occurred due to malfunctioning kidneys, as a result of the Alzheimer’s medications that she was taking. Your “Frequently Asked Questions” section of the website indicates that, on average, patients with Alzheimer`s disease live eight to ten years after diagnosis. How long does Alzheimer`s disease last, on average, for patients if they do not take the conventional treatments. Thank you in advance for your kind assistance. [ 08/30/13 ]
I am sorry for your loss, and many grieving individuals question whether medications prescribed during a terminal illness were more harmful than beneficial. The medications for Alzheimer's disease are not thought to either decrease or increase survival time; however, quality of life is modestly improved for some affected people and their caregivers. Ascites is more typically caused by liver failure than by malfunctioning kidneys, and it is more often the case that malfunctioning kidneys alter the effects of medications rather than vice versa.
My partner of 20 years was diagnosed with Alzheimer’s eight years ago. Around 21 years ago, he was also diagnosed with Lewy Body disease. He weighed 212 pounds when first diagnosed, but now he weighs 129 pounds, is totally bed-ridden, and speaks very little. He eats well most of the time and sleeps as soon as he has eaten. Is this normal? He is still taking Namenda, twice daily, one Zoloft 100mg daily, 1/2 of a 10 milligram Norvasc daily, and one K DURx daily. Does the combination of these drugs cause sleepiness? [ 06/20/13 ]
Your partner has survived for an astounding number of years despite serious illnesses. I am not sure how his clinicians have distinguished between his Alzheimer’s disease and his Lewy Body disease, but both of these can interfere in so many ways with cognitive, emotional, behavioral, and physical functioning. As these diseases progress, an individual may require more hours of sleep each day, and sleep may be more fragmented. It would not be unusual to sleep after eating. The medications he is taking are not typically associated with increased sleepiness, but individuals can react idiosyncratically to medications so it is not impossible that his Namenda, Zoloft, or Norvasc might increase his sleepiness. Progression of his disease(s), however, is a more probable explanation.
My mother-in-law has dementia, which was diagnosed about two years ago. She takes Aricept, two Advil PM at bedtime, and melatonin to help her sleep through the night. It doesn't work. She still forgets what she said or asked, and forgets if family members have passed on or not. As her primary caregiver, I work full time while she goes to adult daycare, which picks her up each morning. She wakes up several times at night, gets dressed and waits by the front window watching for the bus at all hours. I've placed brightly colored sticky notes throughout the house, on windows, mirrors, and clocks, saying "Mary: The bus comes at 8 am. What time is it now?" I've placed the notes on the clocks and placed clocks everywhere in the house. She takes the notes down, but still waits by the front window watching for them in the dead of night. Do you have any suggestions on how to keep her from waking up and staying up all night waiting for the bus? We've taken her off any caffeinated drinks, but that [ 06/20/13 ]
Alzheimer’s disease and other dementias have profound effects on sleep. Alzheimer’s, in particular, is known to interfere with the continuity of sleep, so many affected people wake intermittently during the night. You’re right to eliminate caffeine and other stimulants from her diet. Prepare a restful sleeping area for her, too, and avoid excessive emotional stimulation before bedtime. Controlled release melatonin helps some Alzheimer’s patients remain asleep longer. Other medications are sometimes used, but please consult your mother-in-laws clinicians about this because they will balance the potential benefits of increased sleep with the risks that these medications bring, which include increased confusion and fall risk.
My mother was diagnosed with Alzheimer's disease around seven years ago. She is currently living in a nursing home and I noticed lately she has been sleeping more than usual. Last night, while visiting with her, I tried to wake her and she wouldn't wake up. Even the nurse shook her and took her vitals. She was fine, but had a slight fever. I also noticed that her breathing was more rapid than usual. Does this mean she is shutting down? Her medications have been reduced and she still sleeping as if she is in a coma. [ 06/20/13 ]
As Alzheimer’s disease progresses, it is common for affected individuals to require more sleep. Fever and rapid breathing, however, may indicate the presence of an infection. The urinary tract, the lungs, or the skin are common sites of infection in people with advanced Alzheimer’s, and the clinicians caring for your mother may wish to assess for the presence of an infection affecting her temperature and breathing.
My father and several aunts had Alzheimer's disease and it concerns me greatly. I understand that some studies are showing the presence of metals in the brain and I've heard we should not be cooking with cast iron. Is that true? If so, what is the best material for cookware? [ 06/19/13 ]
Because the ultimate cause of Alzheimer’s disease is not yet certain, the search for modifiable lifestyle risk factors is very compelling. There is research exploring the risk-reducing value of addressing medical disorders such as diabetes, paying attention to nutrition, engaging in appropriate levels of physical activity, and maintaining cognitive stimulation and social connections. The relevance of various environmental exposures has also been explored, and the possible role of cookware in increasing the risk for Alzheimer’s has been debated for decades. Cookware made of cast iron, stainless steel, or aluminum has the potential for exposing users to trace amounts of metals. Concerns have also been raised about zinc and copper. A definitive link between exposure to metals and Alzheimer’s has not been established, though concerns about the toxicity of these metals, most frequently aluminum, have not been entirely laid to rest. Enameled cast iron or stainless steel has been recommended as most safe, but the food that you eat is probably a much more important risk factor than the cookware you use to prepare it.
My wife, who is 59 years old, suffers from severe and rapidly progressing Alzheimer’s disease. From the onset, her eyesight has been compromised. She sees, but can no longer watch the television and walks with great difficulty. Our doctor indicates nothing is wrong with her eyes, but there does appear to be a problem somewhere between her eyes and her brain. I would appreciate any perspective that you have on Alzheimer’s disease and loss of vision. [ 06/19/13 ]
The process of vision places demands not only upon the eyes but also on the brain. The eyes are the sensory organs that take in light and convert sensory input into the nerve impulses that are transmitted to visual centers in the brain. In Alzheimer’s disease, and particularly in the posterior cortical variant of this brain disorder, visual function can be greatly disturbed. Even though nothing is wrong with the eyes themselves, the brain’s inability to understand the signals it is receiving can produce symptoms such as you have described.
