- uraemic seizures
2
Q

- altered mentation or generalised forebrain signs such as seizures
3
Q
Cause of hepatic encephalopathy

5
Q
Fill in the gaps: all animals less than xx months of age which present with xx should be screened for HE secondary to congenital xx xx
A
- All animals less than 12m/o which present with seizures should be screened for HE secondary to congenital portosystemic shunting
– they rarely present with seizures related to feeding

A
- generalised changes in the brain, so present with progressive forebrain or vestibular signs
8
Q
Prevalence of thiamine deficiency
A

9
