Answer 1

10. Stroke affecting both sides of the pons can result in a syndrome known as “locked in”. Hence, option “d”’ is correct.

1. Dissociated sensory loss is most likely to occur following a stroke in posterior inferior cerebellar artery. Hence, option “E “ is correct.
2. Acetylcholine esterase inhibitors are proved to be the one of the best drugs for myasthenia gravis (MG).Hence, option “E” is correct.
3. Huntington's chorea, disorder that occurred due to death of brain cells, is a autosomal dominant disease. Hence, option “c” is correct.
4. Amyloid Plaques and Neurofibrillary Tangles are one of the most common symptoms of Alzheimer disease. Hence, option “ b” is correct.
