Alzheimer's disease. Ten-minute Alzheimer's test to spot disease in earliest stages before brain is badly damaged. By Fiona Macrae Science Correspondent Published: 23:05 GMT, 21 May 2012 | Updated: 23:05 GMT, 21 May 2012 A ten-minute memory test that picks up Alzheimer’s disease and other forms of dementia in their earliest stages is available for use in GPs’ surgeries from today.
The test distinguishes between normal forgetfulness and the more dangerous memory lapses that can signal dementia. Early diagnosis would allow patients to receive drug treatment when it would help them the most, letting them work and live independently for longer. Quick: A simple ten-minute test on a computer will effectively screen patients for early signs of Alzheimer's and allow faster treatment Barbara Sahakian, the Cambridge University professor who helped develop the CANTABmobile test, said that to catch people before the brain became too badly damaged, the computer program should be used to screen everyone over 65. The quick test is designed to identify memory lapses that occur very early in the onset of dementia. People in their 60s are hit hardest by Alzheimer's as it progresses more quickly.
May be that patients diagnosed after 80 have some kind of 'resistance' to condition By Claire Bates Published: 12:08 GMT, 3 August 2012 | Updated: 12:12 GMT, 3 August 2012 People who develop Alzheimer's symptoms in their 60s and 70s, are more likely to decline quickly compared to those diagnosed in very old age, researchers say.
A team from the University of California said the 'younger elderly' showed faster rates of brain tissue loss and cognitive decline than Alzheimer patients who were over 80 years old. The findings have profound implications for both diagnosing the degenerative condition and efforts to find new treatments. Early-onset: Author Terry Pratchett revealed when he was 59 that he had been diagnosed with Alzheimer's Disease. Study author Dr Dominic Holland, said: 'One of the key features for the clinical determination of AD is its relentless progressive course.
Alzheimer's Disease (Alzheimer's) Heimer's Association - What is Alzheimer's. Alzheimer's Disease Fact Sheet. Alzheimer’s disease is an irreversible, progressive brain disease that slowly destroys memory and thinking skills, and eventually even the ability to carry out the simplest tasks.
In most people with Alzheimer’s, symptoms first appear after age 60. Estimates vary, but experts suggest that as many as 5.1 million Americans may have Alzheimer’s disease. Alzheimer’s disease is the most common cause of dementia among older people. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities, to such an extent that it interferes with a person’s daily life and activities. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must depend completely on others for basic activities of daily living. Agitation in Older Persons With Dementia. Dementia%202. Is it Alzheimer’s or Another Dementia?
Distinguishing between Alzheimer’s and other types of dementia Key Points More than 50 conditions can cause or mimic the symptoms of dementia.
A small percentage of dementias are reversible. Symptoms subside when the underlying problem is treated. Two common examples are dementia caused by vitamin B12 deficiency or an underactive thyroid (hypothyroidism). For physicians and families intent on pinning down a diagnosis, one major complicating factor is the existence of so many kinds of dementia. Alzheimer’s disease is by far the most common intractable condition.
In some types of dementia, treatment will improve mental functioning, and in a small percentage, the dementia is completely reversible if treatment begins before permanent brain damage occurs. Reversible dementias Reversible dementias are often easier to diagnose than irreversible dementias because they are usually accompanied by other, obvious symptoms. Delirium Speed of onset. Toxic reactions to drugs Depression Pseudodementia. Protein Tweak May Trigger Alzheimer’s. Like a prion, Alzheimer's protein seeds itself in the brain. The Alzheimer’s-related protein amyloid-beta is an infectious instigator in the brain, gradually contorting its harmless brethren into dangerous versions, new evidence suggests.
The study adds to the argument that A-beta is a prion, a misfolded protein that behaves like the contagious culprits behind Creutzfeldt-Jakob disease in people, scrapie in sheep and mad cow disease. In human cells grown in a dish, amyloid-beta (red) moves from a nerve cell with many A-beta molecules (right) to an unaffected cell (green, left) via a cell-to-cell connection. Sangeeta Nath Amyloid-beta taken from the brain of one mouse was injected into a second mouse brain (shown); 300 days later, the protein had spread throughout and formed deposits (dark spots). J. Dementia: Can Alzheimer's disease be delayed by a chemical found in PINE CONES? Compound found to prevent formation of plaques that stop brain cells from working effectively in Alzheimer's patients By Claire Bates Published: 09:29 GMT, 2 August 2012 | Updated: 10:21 GMT, 2 August 2012 A once-a-day tablet that harnesses a chemical found in pine cones shows great promise in both preventing and slowing the progress of Alzheimer's disease.
The drug, known as NIC5-15, has been shown in animal studies to be effective in preventing the formation of amyloid plaques. These are believed to coat the brain cells stopping them from working effectively.
