17
Q

What is the major concern that can occur with alcoholism (disorder)

A

Wernickes Encephalopathy/Korsakoffs Psychosis

18
Q

What is Wernickes Encephalopathy/Korsakoffs Psychosis- how does it occur, what are the symptoms, how can it progress?

A

Alcoholism can lead to thiamine deficiency which then leads to developement of WE/KP-> WE is the physiological component and causes nystygmus, ataxia and opthalmalgia-> KP is the psychological symptom and causes confabulation/memory loss
-> It is preventable but can be irrevesible and leave people in a constant state of confusion

19
Q

How do you treat WE/KP

A

If there is nystgymus/thought that the patient may have WE/KP administer large doses of thiamine

20
Q

What is the role of thiamine

A

Thiamine is required for myelin/fatty acids/steroids and glycolysis to work (the enzymes in this pathway require thiamine)-> without thiamine the brain will not function

21
Q

What are the complications of alcohol withdrawal

A

seizures, vomiting, confusion, delirium tremors, extreme agitation, tachycardia, paranoia, hypertension, high temp-> can be fatal

22
Q

What medication is given to alcoholics going through withdrawal-> why must administration be monitored

A

Benzodiazepines-> need to monitor patient and only give small doses and benzodiazepines are also highly addictive-> don’t want to replace one addiction with another
