Main Symptoms, Classifications, and Emotional Impacts of Aphasia

Administrative and Course Logistics

  • Class Session Poll: Regarding the last class session, the poll results indicate July 1 is a preferred date.
  • Grading and Assignments: The instructor is willing to push out assignment deadlines or provide more time if students encounter scheduling issues. Students are encouraged to contact the instructor directly to work through specific problems.
  • Clinical Training and Observations:
    • There are two remaining sessions for registration: June 24 in the morning and July 1 in the morning.
    • There is a customization session focusing specifically on an app.
    • Observation Requirement: Students are only required to observe one clinical session.
    • Warning regarding scheduling: Many sessions occur on Thursdays during class time, which may present feasibility issues for some students' schedules.

Multi-Modality Disorders in Aphasia

  • Definition and Understanding: Aphasia is described as a multi-modality disorder. While some students use the specific term "multi-modality," others describe the concept by explaining that they are not succinctly understanding in writing or other forms.
  • The Four Modalities of Language: All four core modalities are typically affected in aphasia in varying degrees of severity:
    1. Auditory Comprehension.
    2. Reading.
    3. Speaking.
    4. Writing.
  • Profile Analysis (Graph Representation):
    • The instructor presented a graph with Percentage Accuracy (0 to 100%0\text{ to }100\%) on the vertical axis and Modality on the horizontal axis.
    • Patient Profiles:
      • Patient 1 (Blue): Represented as the less severe case. Accuracy metrics include approximately 75%75\% in auditory comprehension and 60%60\% in reading. Speaking accuracy drops to approximately 40%40\%, with writing being significantly more impaired.
      • Patient 2 (Orange): Represented as the more severe case. This patient follows a similar pattern of deficit across modalities but at much lower accuracy levels.
    • Clinical Implications: Testing must cover all four modalities because aphasia touches every aspect of language processing, even if one modality (like speaking) is more overtly affected than others.

Main Symptoms and Classifications of Anomia

  • Anomia Overview: Anomia is the core symptom involving difficulty retrieving words or labels for things.

  • Three Primary Causes/Types of Naming Deficits:

    • Motor Issue (Motor Speech Disorder):

      • The patient knows the word they wish to say (recognition is intact).
      • The patient can produce the word in a different modality (e.g., they can write "cup" perfectly but cannot say it).
      • Commonly seen in Broca’s aphasia because the damage often overlaps with motor areas of the brain.

    • Word Selection Anomia (True Anomia):

      • The patient knows what the object is (e.g., viewing a picture of a cat and recognizing it as a cat).
      • They cannot produce the word verbally OR in writing.
      • Tip-of-the-Tongue Phenomenon: Patients showing high recognition and excitement (e.g., saying "It's a… it's a…") but the word remains inaccessible.
      • Clinical Indicator: This is the most common form of anomia seen across various aphasia types.

    • Semantic Anomia:

      • The structural "storehouse" for words in the brain is effectively destroyed.
      • The patient does not recognize the object when shown a picture (no "it's a…" reaction; they simply stare).
      • The word exists in no modality (cannot speak it, cannot write it).
      • Associated with poor auditory comprehension.
      • Clinical Indicator: Rare, but commonly associated with severe global aphasia. Global aphasia may morph into other types over time, but those who remain globally aphasic often exhibit this.

Emotional Experience and Impact of Anomia

  • Subjective Emotional Experience: A 2022 survey study identified major themes regarding the emotional toll of word-finding difficulties:

    • Negative Emotions: Primarily extreme frustration.
    • Perceptions of Breakdown (Mechanism): Patients describe breaks in memory or word expression mechanisms.
    • Impact on Relationships: Social and family isolation. High impact on interactions with children and friends.
    • Management Strategies: Coping mechanisms to handle or avoid moments of anomia. Some patients choose to stop talking or avoid social situations (Grocery store example: forgetting the word "avocados" and changing the subject/leaving out of embarrassment).
    • Frequency: Reports of anomia often decrease over time for some, while others report it staying the same for years (e.g., "1515 years of frustration.")

  • The Scope of Counseling: Speech-Language Pathologists (SLPs) must engage in empathetic listening. Part of the professional scope involves referring patients to specialized resources if depression becomes a barrier to therapy, such as psychologists familiar with brain injury/aphasia or psychiatrists for medication management.

Fluency in Aphasia: Fluent vs. Nonfluent

  • Nonfluent Aphasia:

    • Phrase Length: Very short (1 to 21\text{ to }2 words).
    • Content: Sparse, mostly content words (nouns); very few function words (prepositions, adjectives).
    • Articulation: Labored and effortful.
    • Prosody: Impaired block contour/intonation due to low word production.
    • Example (Appointment Description): "Monday… ah… dad and calls… dad… hospital… two doctors in thirty minutes… Wednesday… 09:0009:00… Thursday… 10:0010:00… doctors… teeth."

  • Fluent Aphasia:

    • Phrase Length: Normal or increased length (5 to 8+5\text{ to }8+ words).
    • Content: High volume but lacks clear content words (nouns); heavy reliance on pronouns (he, she, it) without referents.
    • Articulation: Smooth with no articulation errors; no apparent effort.
    • Prosody: Normal up-and-down intonation.
    • Logorrhea/Press of Speech: A phenomenon where speech flows out uncontrollably and may be hard to understand.
    • Example (Cookie Theft Description/Paragrammatism): "Well, this is others away here working her out over here to get her better… one of their small tile into her time here… the two boys work together, and one is sneaking around here making his, you know, his whole cost of work as it's further funus…"

Specific Verbal Errors (Paraphasias)

  • Lexical Paraphasias (Real Word Errors):

    • Semantic Paraphasia: Substituting a word related in meaning (Target: Cat (\rightarrow) Response: Dog).
    • Formal Paraphasia: Substituting a word related in sound (Target: Cat (\rightarrow) Response: Cap).
    • Mixed Paraphasia: Related in both sound and meaning (Target: Telephone (\rightarrow) Response: Telegraph).
    • Unrelated Paraphasia: No clear relationship in sound or meaning (Target: Tiger (\rightarrow) Response: Flag).

  • Non-Lexical Paraphasias (Non-Word Errors):

    • Phonemic Paraphasia: A non-word related in sound to the target (Target: Cat (\rightarrow) Response: Dat).
    • Neologistic Paraphasia: A non-word with no remote relationship to the target (Target: Tiger (\rightarrow) Response: Gowee/Funnus).

Agrammatism vs. Paragrammatism

  • Agrammatism:

    • Associated with nonfluent aphasia.
    • Omission of grammatical morphemes (function words and inflections).
    • Speech is hesitant and effortful.

  • Paragrammatism:

    • Associated with fluent aphasia.
    • "Talking around" grammar; includes substitutions of grammatical morphemes rather than just omissions.
    • Often called "Word Salad" or "Jargon."

Additional Signs and Symptoms

  • Auditory Comprehension Issues: Inability to follow questions or commands.
  • Perseveration: Getting "stuck" on a previous word or idea and repeating it in response to different stimuli.
  • Echolalia: Echoing the speech of others (less common in aphasia, more associated with Autism Spectrum Disorder).
  • Alexia and Agraphia: Related to reading and writing deficits, to be covered in later sessions.

Questions & Discussion

  • Question: How do you treat someone with symptoms of semantic anomia where the storehouse of words is gone?
  • Response: Direct treatment on retrieving those specific words may not be effective. The focus shifts to Augmentative and Alternative Communication (AAC). This involves basic devices or tools to communicate essential needs like "pain," "hungry," "thirsty," or "bathroom."
  • Question: Regarding the Argentinian man in the video who is a non-original English speaker—how does bilingualism add complexity to the aphasia diagnosis?
  • Response: This involves looking at recovery patterns in bilingual or trilingual individuals. Clinical questions include: Does the impairment look the same across both languages (L1 and L2)? Do the deficits mirror each other? Sometimes recovery patterns differ between the first and second languages.
