Cognitive screening, level of consciousness, pupillary assessment, and stroke recognition
Neurological assessment in home care ranges from brief cognitive screening to recognition of acute neurological emergencies. Home health clinicians are often the first to detect subtle changes in neurological status that signal deterioration — making systematic assessment and prompt reporting essential clinical skills.
Assessment begins with level of consciousness using the AVPU scale: Alert (awake and aware), Verbal (responds to voice), Painful (responds to pain stimulus), Unresponsive. Any decline from Alert to a lower level is a significant finding requiring immediate clinical notification.
Orientation is assessed in four domains: person (knows their name), place (knows where they are), time (knows the date, day, month, year), and situation (understands what is happening). Document as "oriented x4" for full orientation or specify deficits (e.g., "oriented x2 — person and place; disoriented to time and situation").
The Mini-Cog is a brief, validated cognitive screen that combines 3-word recall with a clock drawing task. It takes 3–5 minutes, requires no special training, and has sensitivity comparable to longer tools for detecting dementia. A score of 0–2 on recall with an abnormal clock drawing suggests cognitive impairment; clinical follow-up is warranted.
The GCS provides a standardized measure of consciousness across three domains: eye opening (1–4 points), verbal response (1–5 points), and motor response (1–6 points). Maximum score is 15 (fully awake and responsive). A score of 8 or below indicates severe impairment and is an emergency. GCS is most useful for tracking changes over time in acutely ill clients.
Assess pupils using the acronym PERRLA: Pupils Equal, Round, Reactive to Light, and Accommodating. Normal pupils are 2–5mm in diameter and should constrict briskly when light is directed at them. Unequal pupils (anisocoria) with one fixed and dilated is a neurological emergency suggesting uncal herniation. Bilateral fixed and dilated pupils indicate severe brainstem dysfunction. Either finding requires calling 911 immediately.
Delirium (sudden onset, fluctuating course, often reversible) must be distinguished from dementia (gradual onset, progressive, chronic). New or sudden confusion in an elderly home care client is delirium until proven otherwise — do not attribute it to dementia without ruling out acute medical causes. Common causes include UTI, medication toxicity, electrolyte imbalance, hypoxia, and pain. Notify the supervising clinician immediately for sudden confusion.
All home health clinicians should know the FAST acronym: Face drooping (uneven smile), Arm weakness (one arm drifts down), Speech difficulty (slurred or strange), Time to call 911. In a client with a known stroke history, be alert to any new neurological symptoms — face, arm, leg weakness, sudden severe headache, vision changes. Time to treatment is the most critical variable in stroke outcomes.
