Discussion: Foundational Neuroscience -NURS 6630

As a psychiatric mental health nurse practitioner, it is essential for you to have a strong background in foundational neuroscience. In order to diagnose and treat clients, you must not only understand the pathophysiology of psychiatric disorders, but also how medications for these disorders impact the central nervous system. These concepts of foundational neuroscience can be challenging to understand. Therefore, this Discussion is designed to encourage you to think through these concepts, develop a rationale for your thinking, and deepen your understanding by interacting with your colleagues.

Assignment: Assessing and Treating Clients With Dementia

The Alzheimer’s Association defines dementia as “a general term for a decline in mental ability severe enough to interfere with daily

life” (Alzheimer’s Association, 2016). This term encompasses dozens of cognitive disorders of impaired memory formation, recall, and communication. The care and treatment of clients with dementia is dependent on multiple factors, including the stage of dementia, comorbidities, family support, and even the care setting. In your role, as the psychiatric mental health nurse practitioner, you must be prepared to not only treat clients with these various cognitive disorders, but also the multiple behavioral issues that often accompany them. For this Assignment, as you examine the client case study in this week’s Learning Resources, consider how you might assess and treat clients presenting with dementia.

BACKGROUND

Mr. Akkad is a 76 year old Iranian male who is brought to your office by his eldest son for “strange behavior.” Mr. Akkad was seen by his family physician who ruled out any organic basis for Mr. Akkad’s behavior. All laboratory and diagnostic imaging tests (including CT-scan of the head) were normal.

According to his son, he has been demonstrating some strange thoughts and behaviors for the past two years, but things seem to be getting worse. Per the client’s son, the family noticed that Mr. Akkad’s personality began to change a few years ago. He began to lose interest in religious activities with the family and became more “critical” of everyone. They also noticed that things he used to take seriously had become a source of “amusement” and “ridicule.”

Over the course of the past two years, the family has noticed that Mr. Akkad has been forgetting things. His son also reports that sometimes he has difficult “finding the right words” in a conversation and then will shift to an entirely different line of conversation.

SUBJECTIVE

During the clinical interview, Mr. Akkad is pleasant, cooperative and seems to enjoy speaking with you. You notice some confabulation during various aspects of memory testing, so the PMHNP performs a Mini-Mental State Exam. Mr. Akkad scores 18 out of 30 with primary deficits in orientation, registration, attention & calculation, and recall. The score suggests moderate dementia.

MENTAL STATUS EXAM

Mr. Akkad is 76 year old Iranian male who is cooperative with today’s clinical interview. His eye contact is poor. Speech is clear, coherent, but tangential at times. He makes no unusual motor movements and demonstrates no tic. Self-reported mood is euthymic. Affect however is restricted. He denies visual or auditory hallucinations. No delusional or paranoid thought processes noted. He is alert and oriented to person, partially oriented to place, but is disoriented to time and event [he reports that he thought he was coming to lunch but “wound up here”- referring to your office, at which point he begins to laugh]. Insight and judgment are impaired. Impulse control is also impaired as evidenced by Mr. Akkad’s standing up during the clinical interview and walking towards the door. When the PMHNP asked where he was going, he stated that he did not know. Mr. Akkad denies suicidal or homicidal ideation.

Diagnosis: Major neurocognitive disorder due to Alzheimer’s disease (presumptive)

Decision Point One

Select what the PMHNP should do:

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-red.pngBegin Exelon (rivastigmine) 1.5 mg orally BID with an increase to 3 mg orally BID in 2 weeks

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-blue.png Begin Aricept (donepezil) 5 mg orally at BEDTIME

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-yellow.pngBegin Razadyne (galantamine) 4 mg orally BID

Decision Point One

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-blue.pngBegin Aricept (donepezil) 5 mg orally at BEDTIME

RESULTS OF DECISION POINT ONE

· Client returns to clinic in four weeks

· The client is accompanied by his son who reports that his father is “no better” from this medication

· He reports that his father is still disinterested in attending religious services/activities, and continues to exhibit disinhibited behaviors

· You continue to note confabulation and decide to administer the MMSE again. Mr. Akkad again scores 18 out of 30 with primary deficits in orientation, registration, attention & calculation, and recall

Decision Point Two

Select what the PMHNP should do next:

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-red.pngIncrease Aricept to 10 mg orally at BEDTIME

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-blue.pngDiscontinue Aricept and begin Razadyne (galantamine) extended release 24 mg orally daily

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-yellow.pngDiscontinue Aricept and begin Namenda (memantine) extended release, 28 mg orally daily

Decision Point Two https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-red.pngIncrease Aricept to 10 mg orally at BEDTIME

RESULTS OF DECISION POINT TWO

· Client returns to clinic in four weeks

· Client’s son reports that the client is tolerating the medication well, but is still concerned that his father is no better

· He states that his father is attending religious services with the family, which the son and the rest of the family is happy about. He reports that his father is still easily amused by things he once found serious

Decision Point Three

Select what the PMHNP should do next:

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-red.pngContinue Aricept 10 mg orally at BEDTIME

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-blue.pngIncrease Aricept to 15 mg orally at BEDTIME x 6 weeks, then increase to 20 mg orally at BEDTIME

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-yellow.pngDiscontinue Aricept and begin Namenda 5 mg orally daily

Decision Point Three

https://mym.cdn.laureate-media.com/2dett4d/Walden/NURS/6630/10/mm/alzheimers_disease/img/pill-red.pngContinue Aricept 10 mg orally at BEDTIME

Guidance to Student

At this point, it would be prudent for the PMHNP to continue Aricept at 10 mg orally at bedtime. Recall that this medication can take several months before stabilization of deterioration is noted. At this point, the client is attending religious services with the family, which has made the family happy. Disinhibition may improve in a few weeks, or it may not improve at all. This is a counseling point that the PMHNP should review with the son.

There is no evidence that Aricept given at doses greater than 10 mg per day has any therapeutic benefit. It can, however, cause side effects. Increasing to 15 and 20 mg per day would not be appropriate.

There is nothing in the clinical presentation to suggest that the Aricept should be discontinued. Whereas it may be appropriate to add Namenda to the current drug profile, there is no need to discontinue Aricept. In fact, NMDA receptor antagonist therapy is often used with cholinesterase inhibitors in combination therapy to treat Alzheimer’s disease. The key to using both medications is slow titration upward toward therapeutic doses to minimize negative side effects.

Finally, it is important to note that changes in the MMSE should be evaluated over the course of months, not weeks. The absence of change in the MMSE after 4 weeks of treatment should not be a source of concern.a
