Formed visual hallucinations are seen in lesions of:: (A) Frontal lobe, (B) Temporal lobe, (C) Occipital lobe, (D) Parietal lobe
Answer is B. The lesions of temporal lobe can cause all types of hallucinations (auditory, visual, olfactory etc). Formed visual hallucinations are elaborate visual hallucinations (e.g a patient may repo seeing a tree with green leaves which has a parrot sitting and a man standing near it) . The presence of elaborate visual hallucinations should raise a strong doubt of an organic cause (i.e. a pathology of brain parenchyma), specifically a temporal lobe pathology.
