STROKE ASSESSMENT AND BRAIN LOBE INVOLVEMENT - QUIZ QUESTIONS


                                             
Scenario 1: Sam had a stroke involving the
occipital area of the brain. His vision was
affected. He was advised by his doctor to
give up his driving privileges. He refused
and drove into a tree.

Scenario 2: Tina's stroke involved the parietal
 lobe. She is having difficulty with distinguishing
right from left and math calculations.
Enjoy the video: The stroke patient

An eye exam may become necessary to check
for visual deficits. Visual acuity testing is done
 from about 20 feet away.

Stereognosis is the normal ability to identify
objects by touching.

Quiz questions
1. Which area of the brain is responsible for vision?
2. What is the parietal lobe responsible for?
3. What testing is done after a stroke?
4. What is stereognosis?

Can you identify brain lobe involvement after a stroke?

Scenario 3: Tom had a stroke which involved 
the temporal lobe. He now has difficulty with 
his hearing and memory loss.

Scenario 4: Ellen was diagnosed with a brain
tumor in the frontal lobe. A tumor resection
was done. Ellen is now showing signs of
 impaired judgement and unsteady gait.

The human brain is made of 2 cerebral
hemispheres: left and right. The corpus
callosum forms a bridge that joins them
 together. Each hemisphere has 4 lobes. 

Millions of nerve cells called neurons
originate in the brain and transmit 
information all over the body. 

The nerve pathways in the brain cross over.
This results in the left brain controlling the
 functions of the right and vice versa.

The frontal lobe, parietal lobe, temporal
 lobe, and occipital lobe.

Frontal Lobe: responsible for motor activity
and judgement/reasoning.
Parietal Lobe: responsible for distinguishing
 right and left; and math calculations
Temporal Lobe: responsible for memory and hearing
Occipital Lobe: responsible for vision


The CNS is the Central Nervous System and is comprised
of the brain and spinal cord. The PNS is the Peripheral
Nervous System and is made of the nerves outside of
the CNS. 
Cranial nerves are part of the PNS.
The optic nerve does not seem to be included.

Quiz questions

1.What is the human brain made up of?
2.What are the lobes of the cerebral hemispheres?
3. What are neurons?
4. What is each lobe responsible for?
5. What are the CNS and PNS?



Scenario: Ann has a pituitary adenoma. She can only
 see half of anything in her visual field.

What is hemianopia?
Hemianopia is a loss of vision (blindness) in half
of the visual field. This may occur in one or both eyes.
