Final answer:
The correct answer is option a) Grandiose.
Step-by-step explanation:
Avidor's belief that he is the prime minister of Israel, despite contradicting evidence, suggests that he is experiencing a grandiose delusion. Grandiose delusions are characterized by an inflated sense of self-importance and a belief in having exceptional abilities, wealth, or fame. In Avidor's case, his delusion is of a high status and power by identifying as the prime minister of a country.
Other types of delusions include:
- Persecutory delusions, where individuals believe they are being conspired against, cheated, spied on, followed, poisoned or harassed by other individuals or organizations.
- Somatic delusions involve a belief that one has a physical defect or medical problem.
- Paranoid delusions, often a subcategory of persecutory delusions, involve intense and irrational mistrust or suspicion, which can lead to a feeling of being threatened or targeted.
In the context of the given question, Avidor does not exhibit symptoms of believing he is being harmed or conspired against, which would be indicative of persecutory or paranoid delusions. Nor does he have a belief related to his body or health, which would be a somatic delusion. Hence, the correct answer is a) Grandiose.
