First Proven Diagnostic Test For Alzheimer's 66

Posted by kdawson from the peace-of-mind-or-otherwise dept.
An anonymous reader writes "A test that can confirm or rule out Alzheimer's disease at an early stage has been shown effective by US pathologists. 'With this test, we can reliably detect and track the progression of Alzheimer's disease,' said lead researcher Leslie Shaw with the University of Pennsylvania's Alzheimer's Disease Neuroimaging Initiative in Philadelphia. ... The new test is detailed in the journal Annals of Neurology. It measures the cerebral-spinal fluid concentration of two biochemicals associated with the disease — amyloid beta42 peptide and tau protein."

      No joke. I think most people when faced with a lumbar puncture would choose to not to know, or to just start taking Aricept blind. A needle in the arm or the ass is bad enough, a needle in the spine is a whole other level of terror.

      • In all honesty, a spinal tap is not that bad of a procedure, provided that the patient relaxes and doesn't try to use their back for a bit after the tap is done. Oh, and yeah, it hurts, but not (from what I've heard) any worse than a needle in the triceps, like a few vaccines.

          I had to hold down my 3 year old daughter while they stuck a needle in her spine. This is a standard test for meningitis.

          If I could have made her relax, or even taken the needle myself, I would have done it. The memory haunts me to this day.

            Dude. I'm no doctor, and I've never had a spinal tap, but it seems like a few millimeters might be a whole hell of a lot more painful when you are talking about drilling into the spinal column.

          I could see choosing even a very unpleasant spinal tap over having AD, but that's not really the choice being offered here. It's having a potentially unpleasant procedure to find out that yes, you do in fact have this disease, about which we can do almost nothing.

          The meds we have now are really piss poor. Do crosswords and hard math problems a lot. It's cheaper and WAY less painful. Plus it might actually help.

      A diagnostic test is useful for finding a cure, though. When doing research, it helps to know who actually has the disease and be able to measure whether it's getting better or worse.

There is a very nice man called Christer who runs the Alzheimers fÃrening (organisation) in Sweden who is *very* active in driving recognition of the disease.

      True. One upside might be that with a working test for Alzheimer's, doctors (especially those who aren't experienced in it) will not put you on other neuro-type treatments for diseases that look somewhat like Alzheimer's. At least then you won't be on unnecessary drugs.

    • If we can find a diagnostic, we might find a way to help prevent/prolong onset, so learning earlier might give a person a better chance to prepare.

      Knowing allows planning - for the person (as best they can), their relatives, friends and people at work. Consider the alternative. You have a person who is slowly but surely (although often with periods of lucidity) losing their memory, their judgment, and acting in increasingly inappropriate ways. This is a serious problem for all concerned.

    Those who don't have a loved one with suspected Alzheimer's Disease (AD) don't even imagine how important this news is. AD is impossible to accurately decisively diagnose before it's moderate to advanced (before that it's just a non-specific Mild Cognitive Impairment), and even then there will always be doubts. AD is only decisively diagnosed after the death of the patient, when a biopsy of cerebral mass is made. No genetic diagnosis egsists, because there are so many genetic modifications that can lead to AD.

    Anyway, this is great news for me, as I do have someone who is suspect to early signs of AD. I hope he can be tested soon.

  • This kind of testing was performed on my wife in the fall of 2006 her in the Netherlands. In de december 2006 she was diagnosed with Alzheimer's Disease based on the test results. I do not know whether this is exactly the same test as described in the article, but I remember having read that it was developed by a Dutch academical hospital.

  • This is indeed really good news as previous testing consisted of cutting open the skull and counting the rings.

    I kid in part, but I could have sworn that the only way to positively diagnose Alzheimer's was in a post-mortem. If it's possible to detect in the very early stages, before it becomes debilitating, those who have it may get a chance to put some things in order and make their wishes (DNR, Long-term care options, etc) known to loved ones.
