PSY625: Biological Bases of Behavior

Case Studies

1.This case is an 80-year-old male who is on an inpatient rehabilitation unit and you are being

asked to see the patient to evaluate him for dementia versus delirium. The patient is a retired

professor who was living alone and independently prior to his injury. He fell on the ice while

retrieving his mail and sustained a right hip fracture. He underwent surgery for repair of his hip

fracture two days prior to your consult. The patient has been exhibiting the following symptoms:

occasional visual hallucinations, confusion about where he is, inconsistent recall as to the reason

he is in the hospital, and behavioral outbursts (e.g., yelling and swearing

at the staff).

2.This case is a 65-yearold married female with 16 years of education. She works full-time as

an elementary school teacher. Her symptoms began suddenly one evening; her husband noted she

referred to the dog food as “Jell-O” and called the television remote a “fork.” She appears to

understand conversational language and can read and write normally, but is unaware of her

paraphasia errors in speech.

3.This case is a 48-year-old male who is referred for an evaluation of behavioral and mood changes. Over the past year, his wife has noticed that he has become increasingly withdrawn and

isolated. He no longer enjoys any type of social interaction and prefers to spend his time alone

playing card games on his computer. He is college educated with no previous significant

medical, neurological or psychiatric history. He works as an engineer and has been at the same

company successfully for the past 20 years. In the past year, his supervisors have noticed that his work

quality has declined and he seems less motivated and “

excited” about his job. Task she had always completed early are now being done late or not at all,

and he appears unconcerned that his job is now in jeopardy.

4.

This case is a 16-year-old female with no previous history of any psychiatric conditions,

learning difficulties, or a diagnosis of attention deficit hyperactivity disorder. She is a high school

sophomore and her parents have noticed that her mood seems

to be “up and down.” She often falls asleep if not involved in a stimulating activity. Tea

cheers at school note good performance on tests, but homework is frequently turned in late and she appears distractible and fidgety during class. She works part-time as a waitress on the weekends but is in danger of losing her job due to frequent tardiness over the past 6 months.

5.

This case is a 19-yearoldmale with 12 years of education who has worked in the field of construction successfully for the past two years. His girlfriend stated that he is often inattentive;

she finds that he “spaces out” when they are talking and she frequently has to repeat information

to him. He was involved in a car accident 6 months prior and sustained a very brief loss of

consciousness, but his Glasgow Coma Scale at admission to the EDwas 15/15. There was no evidence of pre-or post-traumatic amnesia.
