hi, can I please get help on a case study on nueroanatomy I have been struggling for a couple of hours now and can't seem to understand the study to answer the following questions. is there any way or format that i can get help. I would really appreciate it.

thanks!

1. Based on the information in the case, what is the most likely neuroanatomic location for a single lesion that can explain all of the patient’s symptoms and signs? In your own words, explain how you arrived at that localization.

2.What are some possibilities for the nature of the lesion (e.g., stroke, tumor, trauma, etc.)? In your own words, explain your rationale for these options.

3. How does the laboratory data and neuroimaging demonstrate the actual lesion for the patient? Describe how you interpret the data in your own words.

4.How was the patient was treated, and how did they subsequently fare? Describe the treatment plan in your own words.

Chief Complaint
A 67-year-old man was found at the bottom of a flight of stairs, lethargic and smelling of alcohol.
History
Little information could be obtained from the patient. He was discovered at the base of a staircase intoxicated and with a posterior scalp
laceration and was therefore brought to the emergency room.
Initial Physical Examination
General appearance: An unkempt man lying on a stretcher.
Vital signs: T = 98°F, P = 90, BP = 176/89, R = 20.
Head: Scalp laceration over right occipital area; normal tympanic membranes (see Table 3.9).
Neck: In cervical stabilization collar put on by emergency personnel.
Lungs: Clear.
Heart: Regular rate with no murmurs, gallops, or rubs.
Abdomen: Normal bowel sounds; soft, nontender.
Extremities: No edema, normal pulses.
Rectal: Normal tone, heme negative.

Neurologic exam:
Mental status: Lethargic but arousable, with garbled speech. Stated his full name but did not know his location d.
date. Did not recall what happened to him, saying “I'm all right." Followed simple commands.
Motor: Able to move all four extremities.
Clinical Course in the Emergency Room
The initial impression of the emergency room personnel was that the patient was intoxicated with alcohol and perhaps had a mild
concussion, both of which were likely to improve with observation over the next few hours. The patient was sent for X-rays of the cervical
spine and chest. His blood alcohol level came back at 325 mg/dl (>100 mg/dl can cause intoxication, although chronic users can develop

He then became increasingly somnolent and developed irregular respirations, requiring emergency intubation and mechanical
ventilation. A second, rapid but more detailed neurologic exam was done, and the patient was taken for an emergency head CT scan.
Follow-up Physical Examination
Vital signs: P = 95, BP = 184/90.
The remainder of the general exam was unchanged.
