I have frontotemporal dementia? Should I do all the things that are supposed to help people with Alzheimer’s disease? The front and side areas of my brain have decreased in size, and I have many problems, such as loss of memory for people and places. [ 04/09/11 ]
Frontotemporal dementia (FTD) comprises a group of disorders that are separated from Alzheimer's disease by their different microscopic pathologic findings in brain tissue, and by their different course of symptoms. No specific medications are FDA-indicated for the treatment of FTD, though many patients are put on cholinesterase inhibitors or memantine in an effort to see if they provide some benefit. The cholinesterase inhibitors such as donepezil, rivastigmine, or galantamine have not been consistently helpful to patients with FTD, however.
Does fluoride cause Alzheimer's disease? [ 04/08/11 ]
The safety of fluoride, added to drinking water as a preventive treatment for tooth decay, has been questioned by various groups concerned about its possible toxicity. With Alzheimer's disease, however, no firm evidence supports a harmful effect of fluoride. To the contrary, there is speculation that fluoride may have a beneficial effect by competing with aluminum for absorption, which is suspected to be neurotoxic; however, this has not been proven.
What are common problems associated with diagnosing Alzheimer's disease? [ 03/22/11 ]
Diagnostic problems generally fall into the categories of "false positives" (people incorrectly diagnosed with the disease who do not have it), or "false negatives" (people who have the disease and are incorrectly diagnosed as NOT having it).
Sometimes the false positives can result from other disorders that affect cognition, such as depression, delirium, medications, substance use, or a wide range of medical disorders. The false negatives can arise when a person's cognitive level prior to becoming ill was so high that functional reserve covers any growing deficit. In addition, since the diagnosis of Alzheimer's disease is based on a clinical syndrome rather than a definitive diagnostic test using blood, cerebrospinal fluid or brain imaging at this juncture, an atypical presentation can confuse clinicians. Some patients present with a disturbance of visuospatial or language functions that are more clearly apparent than the disturbance of cognition, which again confusing matters. When cerebrovascular disease is also present, the diagnosis may be "mixed," or the cerebrovascular disease may distract attention from the Alzheimer's disease. These are some of the common variations and problems in the diagnosis of this neurological disorder.
My mother died of Alzheimer's disease, and she used to tell me that she could feel or hear something changing inside of her head. I often hear something like a cricket sound in my head, and my brother said that he sometimes has that sensation as well. I wonder if my brother and I are experiencing what my mother was describing. Have you ever heard of such a description from people who had Alzheimer's disease? [ 03/21/11 ]
The sensation that you describe has no link to Alzheimer's disease that I am aware of, but is often referred to as one of the characteristic presentations of "tinnitus," which is the perception of sound within the ear that is not related to any external sound. This symptom should be medically evaluated. It often occurs as a consequence of prolonged exposure to high levels of noise, but it can also represent a serious medical condition such as a blood vessel disorder, high blood pressure, narrowing arteries, or even (rarely) brain tumors.
Can colors improve the mood of an Alzheimer’s disease patient? What paintings or colors would most improve their mood? [ 03/15/11 ]
Researchers believe that Alzheimer's disease (AD) patients respond to colors the same as anyone else. Therefore, in the design of a room the goal should be to create a calm peaceful atmosphere to reduce anxiety and agitation. Accordingly, bright colors and vivid patterns should typically be avoided. Instead, soothing pastel shades, light blues, peaches, pinks, greens, and beige are usually recommended colors for use in homes for patients with AD. AD patients may have difficulty discriminating between similar color intensities, such as light blue or light green. Therefore, if you want to want to highlight a particular feature, such as the door to the bathroom, stairs or other obstacles, make sure you use a contrasting color.
As for paintings, one study found that AD patients who were taken to visit an art museum had better recall of paintings that could tell a story, because the patients could remember the story more than the actual picture itself. So it is possible that such “storytelling” paintings may be more interesting and, hopefully, more cheerful than a painting with abstract shapes or designs. That being said, however, because art can be so subjective, you may have to tailor the paintings to fit the patient. For example, if the patient used to be an avid fisherman or hunter, then woodland scenes or scenic rivers might be to his taste, whereas a patient who loved to garden might find pictures of flower gardens and meadows more to her liking. Stick to easily recognizable subject matter in the pictures. Basically, any painting that would make you and most other people smile would be a good choice for an AD patient as well.
My father was diagnosed with Alzheimer's disease around 3 years ago. During the past several months, his talk of suicide has increased. How long do these tendencies usually last? Will he likely continue to have these suicidal thoughts? [ 03/15/11 ]
Depression is a fairly common problem in Alzheimer's disease patients, particularly those in the early stages of the disease who are aware of their own cognitive decline. One study found that a diagnosis of Alzheimer's disease by itself increases the risk of both depression and suicide in elderly patients. This study reported that people who had a higher level of daily functioning (that is, they generally had mild symptoms or were in the early stages of the disease) and had previous suicide attempts were at an elevated suicidal risk. Similarly, another recent study indicated that early diagnosis of Alzheimer's disease or other dementia may actually increase the risk of suicidal thoughts.
If your father is still in the early stages of the disease, he may be aware of his own deteriorating memory and cognition, which may have prompted this talk of suicide. If you have not done so already, please contact your father's physician so that your father can be professionally examined for signs of depression. If formally diagnosed, antidepressant medication may be useful. As the disease progresses and your father becomes less aware of his own cognitive decline, then talk of suicide will likely decrease.
My wife is in the late stages of Alzheimer's disease. Since she has started tube feeding, and has been gagging either to hyper-salivation or from food backing up from her stomach. She has difficulty swallowing secretions. Is there anything that can alleviate this problem? Her gastroenterologist, who inserted the tube, said that this issue is not his department! [ 03/15/11 ]
There are certainly medications that can reduce secretions, and there may be other issues with the tube feeding if food is "backing up." The clinician or specialists in charge of your wife's tube feeding should provide advice; this is often the gastroenterologist and/or the nutritionist. If neither of these can help, a consult from a specialist who can examine your wife is most certainly needed.
Recently I have noticed that my husband will try to mimic a hand motion (i.e. if someone on TV moves their hand in an awkward way or makes a gesture) he will automatically try to do the same. He is immediate in this action, and not like he has thought about it. Has anyone else ever experienced this, and is it a symptom of his dementia condition? [ 03/14/11 ]
Imitating behavior is not unusual in dementia patients, though its clinical significance is not clear. It may reflect reduced power of the normal control we exert on our behavior through our frontal lobes, keeping us from engaging in actions that we would want to normally inhibit.
