A person who suffers from memory distrust syndrome may distrust his or her own memory and be motivated to rely on external (non-self) sources.

 Hypnosis, Memory, Amnesia
This posthypnotic amnesia does not occur unless it has been specifically suggested to the subject, and the memories are not restored when hypnosis is reinduced; thus it is not a form of state-dependent memory.
Reversibility marks posthypnotic amnesia as a disruption of memory retrieval, as opposed to encoding or storage, somewhat like the temporary retrograde amnesias observed in individuals who have suffered concussive blows to the head.
The mechanism for this amnesia appears to be a division of consciousness, such that the subject is unaware of events that would otherwise be memorable.

In contrast to posthypnotic amnesia, which is a disruption in episodic memory, hypnotic agnosia is best construed as a disruption in semantic or procedural memory -- that is, in the subject's ability to access generic, context-free, declarative and procedural knowledge.

Source amnesia is an episodic memory disorder where source or contextual information surrounding facts are severely distorted and/or unable to be recalled.
            As source amnesia prohibits recollection of the context specific information surrounding facts in experienced events, there is also the inclusive case of confusion concerning the content or context of events, a highly attributable factor to confabulation in brain disease.
            Since source amnesia involves the lack of source memory recollection, though the fact itself may be remembered, one would expect the occurrence of source amnesia prominently with pre-mature, deteriorated, or damaged neurological centers responsible for episodic memory.
