Incorrect Question 4 0/0.5 pts If a patient has a stroke that destroys the right side of the thalamus, what will be the most likely impairment? There should be no impairment to somatosensory sensation since perception only occurs via the somatosensory cortex Temperature and touch sensation on the left side of the body will both be impaired Temperature sensation on the right side will be impaired, whereas touch sensation will be lost only on the left side Touch sensation on the right side of the body will be impaired ·Explanation / Answer
Answer b. Temperature and Touch sensation on the left side of the body will both be impaired.
"A stroke in one part of the thalamus will not have the same effect as a stroke in another part." The right hemisphere of the brain controls the movement of the left side of the body so stroke in the right hemisphere often causes paralysis in the left side of the body. This is known as left hemiplegia.
Survivors of right-hemisphere strokes may also have problems with their spatial and perceptual abilities. This may cause them to misjudge distances (leading to a fall) or be unable to guide their hands to pick up an object, button a shirt or tie their shoes. They may even be unable to tell right side up from upside-down when trying to read.
Along with these physical effects, survivors of right-hemisphere strokes often have judgment difficulties that show up in their behaviour. They often act impulsively, unaware of their impairments and certain of their ability to perform the same tasks as before the stroke. This can be extremely dangerous. It may lead them to try to walk without aid or to try to drive a car.
Survivors of right-hemisphere strokes may also experience left-sided neglect. This is a result of visual difficulties that cause them to "forget" or "ignore" objects or people on their left side.
Some survivors of right-hemisphere strokes will experience problems with short-term memory. Although they may be able to recall a visit to the seashore that took place 30 years ago, they may be unable to remember what they ate for breakfast that morning.
