World Alzheimer's Day
Preparations are underway in Geneva for World Alzheimer’s Day, which takes place on the 21st September.
The Swiss Association for Alzheimer’s Research has organised a series of talks at the Kempinski hotel followed by a fundraising event at the Théâtre du Léman.
Nadine Pachta, the Vice President of the association & Anat Koifman, from the organisation committee joined Katt Cullen on the Mid Morning Mix to discuss the disease, what can be done and the series of conferences and gala evening they're hosting across the Kempinski & the Théâtre du Léman on Wednesday 21st September.
More information can be found at www.recherchealzheimer.ch and tickets to the gala evening can be purchased from fnac.ch or at the Théâtre du Léman.
What is Alzheimer’s disease?
Alzheimer’s is a disease of the brain that causes problems with memory, thinking and behavior. It is not a normal part of aging.
Alzheimer’s gets worse over time. Although symptoms can vary widely, the first problem many people notice is forgetfulness severe enough to affect their ability to function at home or at work, or to enjoy lifelong hobbies.
The disease may cause a person to become confused, get lost in familiar places, misplace things or have trouble with language.
It can be easy to explain away unusual behavior as part of normal aging, especially for someone who seems physically healthy. Any concerns about memory loss should be discussed with a doctor.
How Alzheimer’s affects the brain
The brain has 100 billion nerve cells (neurons). Each nerve cell connects to many others to form communication networks. In addition to nerve cells, the brain includes cells specialized to support and nourish other cells.
Groups of nerve cells have special jobs. Some are involved in thinking, learning and memory. Others help us see, hear, smell and tell our muscles when to move.
Brain cells operate like tiny factories. They receive supplies, generate energy, construct equipment and get rid of waste. Cells also process and store information and communicate with other cells. Keeping everything running requires coordination as well as large amounts of fuel and oxygen.
Scientists believe Alzheimer’s disease prevents parts of a cell’s factory from running well. They are not sure where the trouble starts. But just like a real factory, backups and breakdowns in one system cause problems in other areas. As damage spreads, cells lose their ability to do their jobs and, eventually, die.
The changes that take place in the brain begin at the microscopic level long before the first signs of memory loss.
The role of 'plaques' and 'tangles'
The brains of individuals with Alzheimer’s have an abundance of plaques and tangles.
Plaques are deposits of a protein fragment called beta- amyloid that build up in the spaces between nerve cells. Tangles are twisted fibers of another protein called tau that build up inside cells.
Though autopsy studies show that most people develop some plaques and tangles as they age, those with Alzheimer’s tend to develop far more. They also tend to develop them in a predictable pattern, beginning in the areas important for memory before spreading to other regions.
Most experts believe that plaques and tangles disable or block communication among nerve cells and disrupt processes the cells need to survive.
The destruction and death of nerve cells causes memory failure, personality changes, problems in carrying out daily activities and other symptoms of Alzheimer’s disease.
Clinical studies drive progress.
Scientists are constantly working to advance research. But without clinical research and the help of human volunteers, we cannot treat, prevent or cure Alzheimer’s. Clinical trials test new interventions or drugs to prevent, detect or treat disease for safety and effectiveness. Clinical studies are any type of clinical research involving people and those that look at other aspects of care, such as improving quality of life. Every clinical trial or study contributes valuable knowledge, regardless if favorable results are achieved.
