Certainly food sensitivities can cause mental symptoms.  I've just been
reading this: http://tinyurl.com/m3yts  -- very interesting stuff, and
it does, indeed, mention mental symptoms from gluten sensitivity.  (Your
pies would have had gluten in the crust and gravy, no doubt.)

Not saying gluten is the thing (though it bears looking at,) but simply
that yes, mental symptoms from food sensitivities are not at all
unknown, and often go undiagnosed.

Now this kind of behaviour isn't that unusual for him but this was the
first
time I'd seen it come on so quickly and so closely associated with
eating
(which may of course just have been pure coincidence).  Still, if
there may
be a known dietary effect that is aggravating things (many too much
protein
or something?) I'd like to know more.

Anyone seen anything similar?<<

Heard .. of similar ..

Vascular dementia .. lack of blood flow .. immediate induction .. of ..
violent behavior ..

Alzheimers' .. problems / cognition seem to stem somewhat from the
inability of the blood to flow properly to the brain .. evidenced by
improvement by the use of blood thinners.

If one were to wish to do a home based study of this .. phenomenon ..
one 'could' prepare a fat based meal for your father.

They have shown a fat based meal is able to increase the viscosity
pretty .. quickly.

Soooo ..

Blood Flow to Heart Hampered After High-Fat Meal
Mon Apr 1, 5:54 PM ET

NEW YORK (Reuters Health) - While a lifetime of fatty meals can lead to

a heart attack, a study released Monday suggests that chowing
down on just one high-fat meal can interfere with blood flow to the
heart in healthy young men.

In the study, 15 healthy men in their 20s or early 30s consumed a shake

containing a whopping 1,200 calories and 100 grams of fat--roughly the
equivalent of eating a fast-food meal plus dessert. All of the men
underwent a heart test and had blood samples taken before and
after consuming the liquid meal.

The researchers, led by Dr. Takeshi Hozuml of Osaka City University in
Japan, found that 5 hours after the high-fat meal, the ability of heart

arteries to expand and increase blood flow to the muscle--a measure
known as coronary flow reserve--dropped by 18%.

In addition, five men underwent the same tests after consuming a
low-fat 1,200 calorie meal that contained only 10 grams of fat.
In that case, the men did not have a drop in coronary flow
reserve after consuming the meal, according to the
report in the April issue of the Annals of Internal Medicine.

The findings suggest that coronary microcirculation--the tiny blood
vessels that provide oxygen-rich blood to heart muscle--can be
impaired by a high-fat meal.
Although the study did not include people with heart disease, the
results could explain why those with heart disease-related chest
pain, known as angina (news - web sites), can have increased pain
after a high-fat meal. The pain of angina is thought to be due to a
reduction in blood flow to the heart.

The heart, the body's blood pumping organ, requires its own blood
supply to
function properly. Coronary arteries are the main blood vessels that
supply the
blood to the heart, and if a blockage occurs the surrounding vessels
compensate
by expanding in size to keep the proper amount of blood flowing to the
heart.

Doctors have know that a high-fat meals, which increase the amount of
fatty substances in the blood such as triglycerides, can over
time lead to artery clogging and eventually heart attacks.
In the new study, the investigators found that triglyceride levels
jumped
from 140 milligrams per deciliter of blood (mg/dL) after the high-fat
meal, but
only 10 mg/dL after the low-fat meal.

While the researchers were not able to determine if the increase in
triglyceride levels was responsible for the decrease in the heart's
blood flow reserve, the authors say the findings suggest
implications for patients
with heart disease.

sounds like time for a second opinion...

I think its **far** more likely to have been a pure coincidence. For
example, whats so important about 30 minutes in your mind? What did he do an
hour before? Trip over? Maybe it was that. 2 hours? See a story on the TV?
Maybe it was that. 1 minute or 14 minutes before? What exact phrase did you
say to trigger his behaviour?

IMHO this is a great example of the capability of the human brain to jump to
unwarranted conclusions, you have associated one thing that happened
previously with another that happened later, without any good reason,
especially as this isnt the first time its happened, when I started reading
it sounded as if he had never had this type of behaviour before and it was
completely 'out of the blue'. It could have been caused by a myriad of
things (all more likely than a steak pie!), external or internal, including
a vital neuron failing.

Dont worry about diet, go to the doc and enquire after medicines that may be
able to manage these type of delusions. Though from what you have reported
they may not be much help, since I suppose in a way they arent 'delusions',
eg he isnt just imagining that things are occurring like people trying to
kill him, he has just lost his memory and is now back (in his mind) where he
was say 50 years ago, he doesnt know who you are or where he is so he is
logically trying to escape just like you would if you found yourself in a
strange house with people you didnt know who insisted you lived there and
couldnt leave.

This may just be a sign of things to come and you should expect more
behaviour of this type. After all, initially he had very few and very mild
examples of this type of behaviour, and over time they have increased to
more frequent and more serious. Now you have witnessed a very serious
example, and you aren't (I apologise for saying this) thinking clearly,
instead of looking at the big picture (gradually increasing severity and
frequency to a point where he is getting out of your ability to manage) you
have fixed on one episode as if that is the problem, rather than the real
problem, 'dads getting much worse, what should we do if he's like this all
the time?".

I hope you are considering how he can be managed if (as sounds likely) these
episodes get more frequent and more violent. Who normally cares for him?

Jim,

You could test this easily enough - just give him the same meal
elsewhere and see what happens.

I strongly suspect it has nothing to do with food, since in 30 minutes,
he wouldn't have digested the food yet - he might have had time for an
allergy, but not for "too much protein" or anything else along those
lines.

He's got brain damage that is interfering with his ability to recognize
places, people and objects - its pretty common at that stage for them
to think someone has taken away the "real" item, and replaced with a
fake or imposter. That has to be really scary. You say he also has
catastrophic reactions (i.e. flip outs), which is also common - he has
a very limited ability to cope with change, new information, demands,
stress etc.

So - just being in your house out of his familiar surroundings for a
few hours might be enough stress to set him off if he's not having a
great day, particularly if you've been doing things with him like
getting him cleaned up, feeding him etc. The stress of all that might
be cumulative, and pow!
