Successful calculation requires retrieving arithmetic facts from long term memory and using conceptual knowledge to correctly execute mathematical procedures.โฃ
Acalculia Treatment: Number Transcoding
๐ก๐๐บ๐ฏ๐ฒ๐ฟ ๐ง๐ฟ๐ฎ๐ป๐๐ฐ๐ผ๐ฑ๐ถ๐ป๐ด is the process in which numbers are "translated" from one format to another (i.e., converting the written word four into the Arabic numeral 4 or the spoken word "four"). ๐ข ๐ฃ๏ธ โ๐ผ โฃ
โฃ
This skill is deceptively simple, as how we say a number depends on the context it is in (e.g., the number 230 may be said as "two hundred and thirty," while 2:30 PM is said as "two-thirty").โฃ

Cognitive Models of Numerical Processing
How can number processing be conceptualized? ๐ข ๐ง โฃ
โฃ
Models of numerical processing are helpful tools for better understanding the types of arithmetic errors made by people with acalculia. While these errors can be seemingly random upon first glance, theoretical models help provide a framework for recognizing why certain errors are made and how treatment can be individualized to best fit the unique needs of our clients.โฃ
Agraphia Treatment: Sentence-Level Treatment
Agraphia Assessment: Sentence-Level Assessment
Have you ever had a client who writes single words successfully, but struggles when trying to string those words together into sentences? โ๐ผโ๐ซโฃ
โฃ
Agraphia assessment at the sentence-level examines the language skills outside of spelling, such as ๐ด๐บ๐ฏ๐ต๐ข๐น and ๐ฎ๐ฐ๐ณ๐ฑ๐ฉ๐ฐ๐ญ๐ฐ๐จ๐บ ๐โฃ
The Neuroscience of Writing
What areas of the brain have been associated with agraphia when lesioned? ๐ง ๐ฅ โฃ
โฃ
Writing is a complex process, with ๐ ๐๐ก๐ฌ areas of the brain playing a role. This results in large neural networks responsible for the writing process โ๐ผ โฃ
โฃ
That being said, the traditional agraphia classifications do have lesion sites that are associated with them.
Combined Lexical and Sublexical Treatment
In order to correctly write a word, there are a LOT of steps involved ๐งฉ โฃ
โฃ
Therefore, for many people with agraphia there is no one single cause for their writing problems. Rather, there are a variety of language processing components that are compromised and result in difficulty writing single words. โ๐ผ โฃ

Alexia Treatment: Life Participation Approach

Alexia Classifications
When diagnosing an alexia, there are 2 major types of classifications: ๐ฃ๐ฒ๐ฟ๐ถ๐ฝ๐ต๐ฒ๐ฟ๐ฎ๐น ๐๐น๐ฒ๐
๐ถ๐ฎ๐ and ๐๐ฒ๐ป๐๐ฟ๐ฎ๐น ๐๐น๐ฒ๐
๐ถ๐ฎ๐ โฃ
โฃ
๐๐ฆ๐ณ๐ช๐ฑ๐ฉ๐ฆ๐ณ๐ข๐ญ ๐๐ญ๐ฆ๐น๐ช๐ข๐ด affect the early stages of the reading process and involve difficulty perceiving the written word. In a Peripheral Alexia, individual letters may be misidentified and lead to errors such as reading โbookโ for BOOT.โฃ
โฃ
๐๐ฆ๐ฏ๐ต๐ณ๐ข๐ญ ๐๐ญ๐ฆ๐น๐ช๐ข๐ด affect the later stages of the reading process and involve impairments of lexical processing and sublexical processing. In a Central Alexia, the semantic system may be impaired which results in the word COW being misread as โhorseโ (thereby making a semantic substitution).โฃ
Alexia Treatment: Discourse/Paragraph-Level Treatments
Treatment for alexia at the paragraph/discourse-level tends to emphasize metacognitive strategy use and environmental supports. โฃ Approaches you may consider using include:โฃ ๐๐๐๐ฒ๐ป๐๐ถ๐๐ฒ ๐ฅ๐ฒ๐ฎ๐ฑ๐ถ๐ป๐ด ๐ฎ๐ป๐ฑ ๐๐ผ๐ป๐๐๐ฟ๐ฎ๐ถ๐ป๐ฒ๐ฑ ๐ฆ๐๐บ๐บ๐ฎ๐ฟ๐ถ๐๐ฎ๐๐ถ๐ผ๐ป (๐๐๐ฅ๐ฆ), PQRST, and Supported Reading Comprehension Strategies.
Alexia Assessment: Paragraph/Discourse-Level Assessments
When assessing reading skills at the paragraph/discourse-level, emphasis is typically placed on comprehension of stated and implied main ideas โฃ
โฃ
By utilizing a paragraph/discourse-level assessment, youโll get better insight into your clientโs inferencing skills, the effect of text length on comprehension, and better insight into how reading difficulties may impact functional reading tasks in everyday life (such as reading a menu or reading an online news article) โฃ

ORLA is based on a stimulation approach, where repetitive practice through multiple modalities leads to over-learning of skills (and therefore better maintenance of therapy gains)โฃ
Alexia Treatment: Sentence-Level Treatments
Begin Aphasia Therapy with the End in Mind
By beginning aphasia therapy with the end in mind, we are creating our goals and treatment plans with the understanding that we may only be seeing our patients for a limited amount of time. It is imperative then that we work with our patients to determine what it is that they are looking to achieve in treatment and what would be most helpful for them in this amount of time.โฃ
