A review discusses using brain-computer interfaces, artificial intelligence and other physiological measures to assess awareness and intentionality when behavior cannot be reliably observed. It considers how methods developed in acquired brain injury might be adapted for amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases.
Why this matters
For people with severe motor impairment, these approaches could help researchers and clinicians investigate residual awareness or communication when movement or speech is unreliable. The review does not establish a treatment benefit or show that these methods are ready for routine ALS care.
Limitations and context
This is a review, not a new clinical study. The authors say the strongest evidence for covert awareness comes from acquired disorders of consciousness after brain injury, and that this evidence cannot be directly treated as evidence in neurodegenerative disease. The relevance and usefulness of these methods in ALS still need to be established.
