Re: Does an MRI show Alzheimer's?
My MIL has had numerous MRI's and CAT scans, which show nothing but the usual old age degeneration, nothing to explain her behaviour !!!! This has been an ongoing argument for years!! Plus she has a speech problem, and I notice doctors tend to 'feed' her the answers to the mini mental (who is the president, what year is it?? etc etc).
The local lady here that looks after Day Care and Respite, did mention Multi-Infarct Dementia doesn't show up on scans, and some doctors refuse to 'commit' to a diagnosis without 'proof'. Last time I heard, it can only be proven through an autopsy, and my MIL is far from that!!
Multi Infarct Dementia comes from lots of little Transic Eschemic attacks, little brain neurons stop working for a minute and then wake up. Most people get them, but don't notice anything, you may be forgetful but you will remember. Infarct means death of tissue, so that relates to the neuron NOT working at all and dying. They are small enough NOT to show up on any type of scan.
Goodluck, hope this helps, and do let us know how you get on.
