Which of the following is most likely to involve an organic form of memory loss?

Accepted Answer

Korsakoff's Syndrome is a type of organic amnesia that is typically caused by a deficiency of vitamin B1 (thiamine) and is often seen in individuals with alcohol dependency.

The other options (dissociative disorder, limited amnesia, and fugue) are typically associated with psychological or situational factors rather than organic brain damage or dysfunction.

Question 3

Which of the following conditions is preventable?
