Question

You should assume that all stroke patients in this activity are experiencing dysfunction due to the lack of oxygen to the affected area which caused damage to those neurons and they are no longer functioning. Explain the effect of each?

1. Your patient has had a stroke that has affected the left somatosensory association cortex.
2. Your patient has had a stroke that has affected the occipital lobe.
3. Your patient has had a stroke that has affected the hypothalamus.

4. Your patient has been in a car accident and their cerebrum has been destroyed.
5. Your patient has been in a car accident and their brainstem has been destroyed.

Answer 1

Left somatosensory association cortex-

stroke damage to the sensory cortex results in decreased sensory threshold,an inability to discriminate the properties of tactile stimuli or to identify object by toch.

Affected occipital lobe- When stroke affects most of the occipital lobe on one side of the brain,the visual problem that arises is called homonymous hemianopia this describes loss of half of the visual out of each eyes. Sometimes occipital lobe can cause visual hallucinations, illusion and also experience severe vision loss of total blindness.

Affected the hypothalamus- Hypothalamus is a portion that contains a number of small nuclei with a variety of function.one of the most important function of hypothalamus is to link the nervous system to endocrine system via pituitary gland will be affects.it also affects the metabolic process & other activity of the ANS.It is synthesize and secretes certain neuroharmones called releasing harmones or hypothalamic harmones .Above process will be affected.

Stroke also affects body temperature,hunger,thrist fatigue,sleep and cardiac rhythms.

Destroyed Cerebrum - The cerebrum if damage or destroyed it may cause personality issue,loss of senses the or trouble with thinking and learning.

Destroyed brainstem- stroke damage to the brain stem may lead to breathing issue , cardiac centre will be affected and even death.
