Question Details
Cognitive Dysfunction In A Dog
by jenmercier - November 17, 2024    View Case Report
Hi Steve,
Biscuit is a almost 16 yo MN shih tzu mix who presented to me for a QOL evaluation.
He seems constantly hungry but also losing weight. Can't seem to settle, sometimes doesn't sleep through the night. Stares off into space and sometimes startles himself.
Drinking a little more than usual but nothing crazy. Starting to pee and poop in the house now which he never did
Was vomiting bile but pepcid has helped that.
No coughing. No diarrhea
now is eating his own poop as well

vision is poor/cataracts

Pertinent medical history:
perianal carcinoma removed about a year ago- no visual evidence of recurrence
oozing cyst on his neck- doesn't bother him
tried rimadyl previously and he was panting excessively

Medications:
pepcid BID
gabapentin - 50mg BID
omega benefits cognitive, just started

Diet: wellness core senior small bites. wet food on top for meds and enticing


Tongue: pink to light pink with fine cracks
Pulse: deep, vessel tone but soft pulse, somewhat narrow
neutral to warm all over
greasy coat

Diagnostics:
slightly elevated BUN, SDMA, platelets, cholesterol, potassium

Assessment
The owners main concerns are the behavioral changes. To me he has signs of Kidney/Liver Yin deficiency and Blood deficiency and also some Damp Heat and Blood stagnation.
If I try to not overthink it, it seems like there is a lack of Yin so Yang is not achored. Lack of Blood is leading to stasis and Heat.

When I look up cognitive dysfunction, two formulas that could fit are San Piao Xiao San or Ban Xia Bai Zhu Tian Ma

I look forward to your guidance!

Hi Jen,

I definitely see the Yin deficiency, which is very much centered in the Stomach, creating the increased thirst, appetite, gastric concerns, cracked tongue and perhaps even incomplete digestion that is precipitating coprophagy. The Yin deficiency can cause Yang to not be anchored in the evenings, creating restlessness, but the pulse is more indicative (at least when you examined him) of deficiency.

If that is correct, then Yi Guan Jian should help a lot. Besides healing the Stomach, it contains Rehmannia, which greatly enhances cognition in humans and animals.

I often team YGJ with Chai Hu Jia Long Gu Mu Li Tang to help anchor Yang. The two are combined in the formula known as Halscion, if you're using that. You might wonder if you need to start there, but Shao Yang disharmony (calling for CHJLGMLT) is often the underlying cause of Stomach Dryness and thus Yin deficiency. The slightly high platelets suggests that Shao Yang disharmony is present, at least as a root condition that you will likely have to address at some point.

Hopefully this helps you out!

Steve
