<p>I’m a psychologist who works with old people. (Do not construe any of the following as medical advice.)</p>
<p>It is correct that a definitive diagnosis of Alzheimer’s Disease (AD) can only be concluded postmortem. But we can guess at a diagnosis of AD versus Vascular Dementia (VD). AD is characterized by problems centering around short-term memory, and by a progressive and uniform decline in overall functioning. VD centers around executive functioning–the ability to plan an organize–and can be more sudden in onset, and step-wise in decline. People with VD may retain greater cognitive awareness–e.g., not forgetting loved ones names–over time than those with AD.</p>
<p>AD is at least four times more prevalent than VD. And, sadly, if you are 85, your chances are one in two of developing some symptoms of dementia.</p>
<p>People can have mixed dementia–exhibiting symptoms of either. There are also other dementias, such as those associated with Parkinson’s or brain damage from alcholo abuse.</p>
<p>There are also conditions that mimic dementia.</p>
<p>Depression can yield dementia-like symptoms–psuedodementia depression. Sucessfully treat the depression and the symptoms resolve.</p>
<p>Illness at any age can cause delirium. In older people, infections such as pneumonia or urninary tract infections, can mimic demential. Again, treat the disease and the symptoms resolve.</p>
<p>There are also many people with “mild cognitive impairment”–sort of like losing a few miles on your fastball, but you can still get the ball over the plate–a condition that puts you at greater risk for dementia, but which can also remain stable for years.</p>
<p>Forgetting is common at any age, and not as severe with old age as many like to think. As I like to say, “It’s not forgetting that’s the problem, but forgetting you forgot.” I regularly forget where I put my keys, but I told my wife to be concerned only when she sees me wandering around the house not knowing what I’m looking for. (My son tells me I have to be nice to him because someday he will be picking out my nursing home.)</p>
<p>I can, without controversy say, there is no effective treatment for AD or VD. Again, do not take this as medical advice, but drugs such as Aricept and Namenda are a multi-billion dollar boondoggle perpetuated by the pharmaceutical industry. They are marginally only more therapeutic than garlic was against the bubonic plague. It would be a much better use of scarce resources to spend the money on research and palliative care. Aricept, for example, may make a tiny difference, but a difference that has no meaningful consequences in the real world. By way of analogy, my wife is quite nearsighted. Suppose there was a drug that would enable her to see the big E on the top of the eye chart without her glasses, I still wouldn’t get into a car with her unless she had them on. Similarly, there are many studies that show, for example, that taking Aricept will keep you–on average–out of the nursing home for two weeks longer than if you were on no anti-dementia drugs. In the UK, based on findings such as these, anti-dementia drugs can be prescribed only by psychiatrists or neurologists, and not by primary care physicians. Aricept can only be used for the mildest of dementias, not for moderate or severe ones, and Namenda is not prescribable for therapeutic purposes. It is restricted to research purposes only.</p>
