In Balint syndrome all are seen except-
## Core Concept
Balint syndrome is a rare neurological disorder characterized by a combination of visual symptoms, including **simultagnosia** (inability to perceive more than one object at a time), **optic apraxia** (difficulty in moving the eyes), and **optic agnosia** (difficulty in recognizing objects despite intact visual perception). This syndrome typically results from bilateral lesions in the **parieto-occipital regions** of the brain.
## Why the Correct Answer is Right
The correct answer, which is not a feature of Balint syndrome, needs to be identified based on the characteristics of the syndrome. Balint syndrome primarily involves difficulties with visual perception and eye movements. The symptoms include:
- Simultagnosia: The inability to see more than one object at a time.
- Optic apraxia: A problem with voluntary eye movements.
- Optic agnosia: Difficulty in object recognition.
## Why Each Wrong Option is Incorrect
- **Option A:** If it describes one of the classic symptoms of Balint syndrome (e.g., simultagnosia, optic apraxia, optic agnosia), then it is incorrect because the question asks for what is NOT seen in Balint syndrome.
- **Option B:** Similarly, if it describes another symptom of Balint syndrome, it would be incorrect for the same reason.
- **Option C:** This would also be incorrect if it is a known feature of Balint syndrome.
## Clinical Pearl / High-Yield Fact
A key clinical pearl is that Balint syndrome often results from **bilateral parieto-occipital lesions**, which can be caused by conditions such as **stroke** or **cerebral vasculitis**. Patients with Balint syndrome have difficulty navigating through spaces because of their impaired visual perception and eye movement control.
## Correct Answer: D.
