Could medications contribute to dementia?
Alzheimer's disease and other diseases that cause dementia are very destructive, not only for those affected but also for their friends and family. For most forms of dementia, there is no very effective treatment. For example, the treatments available for Alzheimer's disease can slow down a little damage, but they do not reverse the condition. In fact, for most people who take drugs for dementia, it may be difficult to know whether the treatment works at all. Could medications contribute to dementia?
Experts predict that dementia will become much more common in the coming years. We urgently need a better understanding of the causes of this condition, as this can lead to better care and even preventive measures. Could medications contribute to dementia?
New research linking certain drugs with the risk of dementia
A new study raises the possibility that certain drugs may contribute to the risk of developing dementia. Could medications contribute to dementia?
The focus of this research is on drugs with "anticholinergic" effects. These are drugs that block a chemical messenger called acetylcholine, which affects muscle activity in the gastrointestinal tract and the urinary tract, lungs, and elsewhere in the body. It is also involved in memory and learning. Could medications contribute to dementia?
Many drugs have at least some anticholinergic effects, and it is estimated that up to half of older adults in the US take one or more of these drugs. Common examples include: - Could medications contribute to dementia
- amitriptyline, paroxetine, and bupropion (most often taken for depression)
- oxybutynin and tolterodine (taken for overactive bladder) Could medications contribute to dementia?
- diphenhydramine (common antihistamines, as found in Benadryl). So, should you worry about your medication and dementia?These findings are interesting but not definitive, and they do not mean you should stop taking medication because you are worried about developing dementia.First, the study found that the use of certain drugs was more common in people who were later diagnosed with dementia. That does not mean these drugs cause dementia. There are other potential explanations for this finding. For example, some people experience depression during the early phase of dementia. Could medications contribute to dementia? Instead of antidepressants causing dementia, drugs may be prescribed for early symptoms of dementia that have developed. These are called "confounders by indication" and this is a potential weakness of such studies that attempt to link past drug use to future illnesses.Another reason to be cautious about these results is that they can not be used to estimate their impact. the use of drugs on individuals people risk dementia. This type of study looks at risk in large groups, but individual factors (such as smoking or inactivity) may have a far greater impact on the risk of dementia.However, there is reason to be concerned about the possibility that anticholinergic drugs contribute to the risk of dementia. Acetylcholine is involved in memory and learning, and previous studies have shown lower levels of acetylcholine in the brains of people with Alzheimer's disease (the most common cause of dementia in the elderly). In addition, animal studies have shown that anticholinergic drugs may contribute to brain inflammation, a potential contributor to dementia. Could medications contribute to dementia?
What's next? - Could medications contribute to dementia?
Additional research will no doubt provide further information about the potential impact of drug use on the risk of dementia. In the meantime, it's a good idea to review the drugs you used with your doctor before making any changes. - Could medications contribute to dementia
And remember that you may be able to reduce the risk of dementia by not smoking, exercising regularly, and surviving for a healthy diet (rich in fiber, fruit, vegetables, and omega-3 fatty acids). Get your blood pressure and lipids checked regularly, and follow your doctor's advice on how to keep them within the optimal range. Could medications contribute to dementia
Any drug use has potential risks and benefits. Recent research linking certain drugs with the risk of dementia reminds us that the risk of some drugs is found only years after its use becomes commonplace. Could medications contribute to dementia
