Mayo Clinic study finds men with Alzheimer's are misdiagnosed more often than women

Wickedly complex and nuanced response beyond me at the moment, but it is a very good set of questions and deserves at least a start of a reply.

Dementia is a family of diagnoses/conditions. Most are ‘clinical syndromes’ meaning that they are a label applied to a constellation of clinical characteristics that tend to occur in a group. For most of these, a specific diagnosis (which requires knowing the cause and pathologic process) is either not possible at all, or only possible post mortem. The labels serve two purposes: 

provide some degree of predictive information (this pattern usually progresses slowly/fast/episodically, or this pattern tends to cause aggression/incontinence/language problems).
help make educated guesses about what interventions might be useful. (E.g., smoking cessation and control of BP in multi-infarct dementia.)

There are some demented states that have a specific and identifiable cause: b12 deficiency, hypothyroidism. These are relatively uncommon but worth looking for (obviously) and very gratifying when found - if found early enough to prevent permanent damage. (This is in contrast to delirium, where underlying causes are pretty common.)

Alzheimer’s is still a pathologic diagnosis. Technically, it can only be made at autopsy. There is still no accepted accurate test with acceptable sensitivity and specificity. On top of that, the medications used have statistically significant but often clinically meaningless benefits: delaying institutionalization by several months, for example. 

The clinical challenge is that because Alzheimer’s (which is increasingly looking like it has more than one sub-type) is a syndrome rather than a disease, is not easily and reliably differentiated from other dementing processes, can occur in parallel with other dementing processes, and because treatment is minimally effective for almost all dementia, no one wants to be honest about it. Clinicians don’t like to be powerless and patients and family desperately want more optimism and certainty than is usually appropriate.  

The most important two things I found were:

Honest discussion about what we know and don’t know with patient and caregivers.
Focus on management of the environment and robust support rather than on medication.

Dunno if that helps.

Certainly there was no agreed upon way to analyse the potential patients at an early time, such that interventions can be readily administered and monitored.

I do remember conversations which were absolutely normal, reflecting a sense of the information, older memories, good judgement, and then the next day she clearly did not remember that her husband had died  10 years earlier.  Since her older sister also had some form of dementia, it was assumed by most that this was a familial form of Alzheimers--those the physician daughter of the sister who is a neurologist said that neither had Alzheimer's, as per her review.

> Well, Bill, that's a good question that the article didn't address. It does say that men may contract Alzheimer's earlier than women do and that it impacts memory less frequently in men than it does women, hence the diagnostic difficulty. It also says that the disease progresses more rapidly in men than women.

According to the researcher, in addition to memory loss, Alzheimer's is associated with "language impairment, motor disfunction, behavioral issues and apathy". Behavioral issues include being argumentative and the disease often leads to violent tendencies. Being friends with some spouses of Alzheimer's patients, I can't imagine them having survived even the early symptoms without knowing why their husband or wife was acting so erratically. As one girlfriend told me when her husband was diagnosed with early onset Alzheimer's, "At least now I know why he was being such an a-----e."

The expense of seeking a diagnosis wastes money desperately needed for care when the patient is no longer able to be alone.

Perhaps they might add a brain SPECT scan to the list of tests when the other tests come back negative. That's a proven way to identify Alzheimer's before waiting to autopsy the patient's brain.
