A study of drugs

Complete Overview Between part-time jobs, endless classes, and filling out applications for killer summer internships, most college students rarely have time to study. Many are expert procrastinators who put things off until the last minute.

A study of drugs

Story highlights Drugs used for depression and urinary incontinence had the highest risk for new-onset dementia Anticholinergics used for gastrointestinal and respiratory issues did not have an increased dementia risk, study found CNN Many older adults know that long-term use of certain medications can negatively affect cognition and increase one's risk of dementia.

But a new study suggests that some classes of anticholinergic drugs -- particularly those used to treat depression, Parkinson's and urinary incontinence -- carry a higher risk than others.

Some existing anti-cancer drugs may act in part by targeting RNA, study shows

Anticholinergic drugs function by blocking the effects of acetylcholine, a chemical released by nerve cells to send signals to other nerves and muscles. The new study, published Wednesday in the British Medical Journallooked at the risk of new-onset dementia among nearlyolder adults in the United Kingdom.

But those individuals taking other classes of anticholinergics -- including those used for asthma and gastrointestinal issues -- were not at an increased risk of developing dementia compared with matched controls, the study found.

Read More "Previous studies had really only said that anticholinergics were associated with dementia incidence," said George Savvaresearcher of health sciences at the University of East Anglia and a lead author on the study, in a news briefing. Researchers compared how many daily doses of anticholinergic drugs these patients had been prescribed between four and 20 years earlier with a control group of almostmatched individuals.

Specifically, those anticholinergics used for depression e. The exact reasons for the increased risk of dementia among those taking certain anticholinergic medications remain unclear. Levels of acetylcholine are known to be significantly lower in people with Alzheimer's disease, the most common cause of dementia in older adults, according to the Mayo Clinic.

Nootropics (/ n oʊ. ə ˈ t r ɒ p ɪ k s / noh-ə-TROP-iks) (colloquial: smart drugs and cognitive enhancers) are drugs, supplements, and other substances that may improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals. While many substances are purported to improve cognition, . May 30,  · High doses of some commonly used pain drugs like ibuprofen can increase heart attacks, strokes and related deaths by about a third, a study warned on Thursday. The drugs. Designer drugs are synthetically created substances designed to mimic the effects of existing drugs. In this lesson, learn more about the dangers of designer drugs and see examples of types of.

Therefore, some anticholinergic drugs may block the normal activity of acetylcholine in regions of the brain associated with memory and cognition, resulting in Alzheimer's-like symptoms, according to Savva. Why it's so hard to treat dementia The new study is among the largest of its kind and adds to the existing literature linking long-term anticholinergic use with dementia, according to Dr.

Clive Ballardexecutive dean of University of Exeter Medical School, who was not involved in the research. But the new study is the first to look at different classes of anticholinergic medications, according to Savva.

This allowed the researchers to show that some types of anticholinergic medications were not associated with the onset of dementia. Previously, antihistamines have been implicated in dementia riskbut we've not found any association between those specifically and dementia, as well as the gastrointestinal drugs," Savva said.

The study was observational in nature, making it difficult to draw definitive conclusions about causality, according to Dr. Martin Rossorprofessor or clinical neurology at University College London, who was not involved in the research. But particularly as treatment options for many conditions increase, the study adds more weight to the notion that physicians should be proactive about identifying alternatives to anticholinergic medications whenever possible, according to Dr.
