Differentiate between delusions and hallucinations.

Answer:

Dissociative Amnesia is characterised by extensive but selective memory loss that has no specific known organic/biological cause (eg. head injury). Some people cannot remember anything about their past. Others can no longer recalls specific events, people, places, or object, while their memory for other events remain intact. This disorder is often associated with overwhelming stress.

A Delusion is a strongly held false belief despite evidence being provided to the contrary. A person with a delusion has a certain belief that they held on to even if evidence supports the contrary. It is not affected by rational argument and has no basis in reality. Different delusions are delusion of persecution, reference, grandeur and control.

Whereas, Hallucination is a perception without the present of a stimulus. Hallucinations are defined as perceptions in a conscious and awake state in the absence of external stimuli which have qualities of real perception, in that they are vivid, substantial and located in external objective space. Hallucinations can be auditory, tactile, somatic, visual, gustatory and olfactory.
