Aphasia

I have always found aphasia incredibly interesting and terrifying all at the same time. Imagine not being able to communicate with language as smoothly as you do everyday. It is something that many of us take for granted.

Definition:
the loss or defect of language (speaking fluency, reading, writing, understanding of written or spoke words)

What are the 4 types of aphasia?
1. Wernicke's 
2. Broca's
3. conduction
4. global

Potential causes:

  • stroke
  • brain trauma
  • brain tumor
  • alzheimer's disease
Wernicke's
-receptive, fluent aphasia
-pt has hard time comprehending written or spoken language
-fluid speech, but difficult to understand

Broca's
-expressive, nonfluent aphasia
-speech is slow and requires effort
-few words used
-good comprehension of language

Conduction
-disturbance in repetition
-pathology involves the connections between Wernicke's and Broca's

Global
-often associated with RIGHT hemiparesis
-defect in all areas of language


How to treat
-many recover spontaneously in 4-6 weeks
-speech therapy

"call house officer if 2 hour UOP is < 60cc"

What are the possible causes?
Think pre renal/renal/post renal causes

What is the most common cause?
Pre renal!

What if PAs Couldn't Suture Anymore?

This a repost from a call sent out by the AAPA based on a resolution brought to the AMA's House of Delegates. Read it and take part in your future scope of practice as a PA.

Join AAPA in responding to negative AMA resolution

While workforce experts are predicting a shortage of providers with the implementation of the Affordable Care Act, the American Medical Association Board of Trustess is proposing a resolution for its House of Delegates that could severely restrict PAs' ability to provide care to patients. PAs should be very concerned about the resolution, which will be considered by the AMA HOD when it convenes on Saturday, June 15. The recommendations are very restrictive and display a misunderstanding of the way PAs and doctors provide care as part of a team. Among other restrictions, the resolution expands the definition of surgery to include repair and removal of human tissue and, although parts of the resolution are somewhat unclear, states that surgery as defined in the resolution is to be performed ONLY BY PHYSICIANS. If adopted as presented, the resolution will call into question procedures like suturing, punch biopsies and vein harvesting, which PAs perform on a daily basis across many medical specialties. The resolution also proposes that only physicians should perform invasive procedures that utilize radiologic imaging. You can read Report 16 of the AMA Board of Trustees in full here.

AAPA is spreading the word about the negative impact this resolution would have on patient care and PA practice, but we need your help. Please review the list of AMA delegates in your state or specialty, and if you have a connection, please let that physician know the true damage that this resolution could create. Also, talk with and encourage physicians in your practice to speak with other physician leaders about the resolution. AAPA's suggestion is that the resolution should be defeated, or modified to specifically state that it does not apply to PAs practicing within the parameters of state law.

For more information on the AMA resolution please contact Ann Davis, PA-C, MS, Senior Director of Constituent Organization Outreach and Advocacy, at ann@aapa.org.
