Clinical Assessment and Diagnostic Procedures in Speech-Language Pathology

Medical Record Review and Information Sources

• Prior to seeing a client, an exhaustive review of medical records is essential to form predictive theories about the patient's condition.
• Primary Information Sources:
  • Medical Records: These provide the official medical diagnosis and anatomical details of the damage.
  • Medication List: Understanding pharmacological treatments the patient is currently undergoing.
  • EMT Field Notes: Notes from Emergency Medical Technicians are valuable for initial observations regarding speech, language, and motor abilities at the scene of the incident.
  • Emergency Room (ER) Notes: Observations made during the acute phase of hospital admission.
  • Physician's Notes: Documented observations and clinical reasoning from doctors.
  • Nursing Assessments: Unique observational data from the nursing staff.
  • Imaging Reports: CT and MRI reports are the "go-to" imaging sources in a general hospital setting to localize brain damage.
  • Biographical Information: Full name, birthday, address, and phone number. This is crucial for formal assessments (e.g., asking "Do you live in Wahumbra?" requires knowing their actual address to score the answer).

Neuroanatomical Red Flags and Behavioral Predictions

• Left Hemisphere Anterior Damage: Predicts possible aphasia and motor speech disorders due to the proximity of motor areas.
• Left Hemisphere Posterior Damage: Predicts possible auditory comprehension issues and problems with reading or writing; these cases may be less motor-based.
• Significance of Prediction: This clinical reasoning helps the SLP (Speech-Language Pathologist) bring the correct assessment instruments to the initial evaluation.
• Cross Aphasia: Rare cases where the brain damage site and functional symptoms do not align with standard expectations.

The Clinical Interview: Patient-Centered Questions

• Hierarchy of Communication: Always direct questions to the patient first before deferred to family members or caregivers.
• Establishing Clinical Goals:
  • Question: "What are your goals?"
  • Rationale: Ensures therapy is targeted toward what is meaningful to the patient, as their desires are as important as professional clinical opinion.
• Work and Life History:
  • Question: "What did you do for work?"
  • Rationale: Helps tailor therapy tasks to replicate previous functional needs.
• The Chief Complaint:
  • Question: "Tell me what's going on" or "What are you struggling with?"
  • Rationale: Identifies the patient's perspective on their problem.
• Change and Improvement:
  • Question: "Have you seen any change? What does that change look like?"
  • Rationale: Establishes a baseline of spontaneous recovery or previous progress.
• Scheduling Optimization:
  • Question: "What time during the day do you feel at your best?"
  • Rationale: Helpful for scheduling therapy or assessments during peaks of performance, though sometimes working at "worst" times helps build resilience.

Cultural and Linguistic Considerations

• Bilingualism: Determine the native language and which language is spoken most often.
• Clinical Implications: Helps distinguish a true communication disorder from a cultural or language difference. For example, a patient whose primary language is Korean may require a Korean-speaking SLP or an interpreter.
• Recovery Patterns: Investigating if there are different recovery trajectories between the native language and English.

Participation and Quality of Life Factors

• Hobbies and Social Re-engagement: Understanding hobbies (e.g., attending a book club) allows for the "participation approach."
  • Example: If reading is difficult but auditory comprehension is intact, an SLP might suggest audiobooks so the patient can stay engaged in their book club.
• Daily Activities: Assessment of living conditions (living alone, babysitting grandchildren) helps prioritize functional skills.
• Literacy Habits: Determining if a person was a "literary person" before the injury. If they did not read books previously, therapy should not force complex reading tasks, focusing instead on functional reading (street signs, medicine bottles, mail).

Facilitating Communication: Circumlocution and Semantic Analysis

• Circumlocution: A strategy where the patient "goes around" a target word they cannot retrieve.
  • Example: If the target word is "remote control," the patient describes it as "that thing that is rectangular and has buttons on it, and you press the buttons to show slides."
  • Clinical Value: This keeps communication moving and may eventually trigger the target word.
• Semantic Feature Analysis (SFA): A treatment method intended to reconnect the semantic web by describing an item's properties, use, and category.

Clinical Observation and Non-Verbal Cues

• Observations should begin as soon as the SLP enters the room, even before formal questions start.
• Points of Observation:
  • Alertness: Is the patient awake and aware of their environment?
  • Social Greeting: How do they respond specifically to a new person entering? (e.g., do they say "Hi" or respond when their name is called?)
  • Social Support Network: Who else is in the room? This identifies the patient's support network.
  • Motor Abilities: Examine posture and mobility. Note if a side of the body is paralyzed (e.g., hemiplegia). If a right-handed patient has a paralyzed right arm, therapy must shift focus to left-hand survival skills.
  • Body Language and Emotion: Do they show facial emotion? Do they seem motivated (sitting up) or detached/down?
  • Basic Needs: Can they express thirst or pain non-verbally (nodding, pointing)?

Formal Assessment Tools and Frameworks

• ICF Alignment: Assessments should map to the International Classification of Functioning, Disability and Health, though many current tests focus heavily on body functions rather than social participation.
• Diagnostic Data Intake Sheet: Includes an oral motor evaluation, apraxia of speech test, oral apraxia test, and a dysarthria evaluation checklist.
• Assessment Hierarchy:
  • Auditory Comprehension: Starts with easy tasks (yes/no questions) and moves to complex verbal tasks (defining "robin" or "idol").
  • Complex Tasks: Including explaining proverbs.
  • Verbal Formulation: Moving from automatic speech to discourse/conversation.
  • Reading and Writing: Identifying single letters to reading/writing full paragraphs.
• Popular Formal Assessments:
  • Boston Diagnostic Aphasia Examination (Boston).
  • PICA (Porch Index of Communicative Ability): Noted as an older, extremely thorough test that took a long time to complete and has largely fallen out of use.
  • Western Aphasia Battery (Western): Often mandated by specific facility policies.

Differential Diagnosis and Comparison

• Aphasia vs. Motor Speech Disorders: SLPs must differentiate between aphasia (language-based), dysarthria (motor execution), and apraxia (motor planning). Language testing is the primary tool for this distinction.
• Right Hemisphere Disorder (RHD) vs. Aphasia: RHD often involves pragmatics issues, whereas aphasia focuses on content and form.
• Aphasia vs. TBI: Traumatic Brain Injury (TBI) can include aphasia but is often more cognitive-communication focused.
• Aphasia vs. Dementia: Differentiating language loss from cognitive decline.
• Tracking Progress: Using notation like "P" for progress and "D" for discharge based on assessment levels.

Prognostic Predictors in Aphasia

• Powerful Predictors:
  • Initial Severity: More severe language problems at onset correlate with a poorer prognosis.
  • Type of Aphasia: Broca's or Conduction aphasia typically have better prognoses than Global aphasia (which involves significant auditory comprehension issues).
  • Lesion Size and Site: Larger lesions lead to poorer prognoses. Anterior lesions generally have better outcomes than posterior lesions.
  • Time Since Onset: Patients seen before the 6-month mark post-onset typically have better outcomes.
  • Family Support: Presence of a support system improves prognosis.
• Moderate/Weak Predictors:
  • Age: Younger patients may have more neural reserve.
  • Personality: Extroverts may engage more in social communication recovery.
  • Education/Intelligence: Mixed evidence on their impact on recovery.

Referrals and Counseling: The Grief Cycle

• Referrals:
  • Psychologists: For depression related to the illness.
  • Occupational Therapists (OT): For functional daily activities (cooking, dressing, typing emails) and hand therapy.
• Patient/Family Education: Educating on the diagnostic label, severity, goals, prognosis, and the recovery process.
• The Grief Cycle (Kübler-Ross adapted for loss of health):
  • Shock and Denial: Characterized by avoidance, confusion, and numbness.
  • Anger: Characterized by frustration, irritation, and shame.
  • Depression and Detachment: Feeling overwhelmed or experiencing a lack of energy.
  • Dialogue and Bargaining: Reaching out to others and struggling to find meaning.
  • Acceptance: Exploring new options and empowerment.
  • Note on Grief: Grief is "messy" and non-linear. Aphasia represents a profound loss of communication and connection; friends and family often disappear because they cannot handle the "awkwardness."

Questions & Discussion

• Question: Do SLPs usually use severity levels in report writing?
• Response: Some do, but many do not. It can be tricky, but pinning down severity (Mild, Moderate, Severe) is helpful for diagnostic accuracy and treatment planning.
• Student Observation: One student noted the importance of observing religious texts or personal items in the room to understand the patient interests or support.
• Classroom Activity: Students were tasked with designing assessment activities for specific areas (e.g., auditory comprehension at the word level, reading comprehension at the word level) using an intake sheet as a template.
