Resting nystagmus may indicate what?

Resting nystagmus is characterized by involuntary eye movements when the eyes are not fixated on a target, typically indicating a potential neurological issue or disturbance in the vestibular system. The presence of resting nystagmus could suggest that an underlying medical condition is present, such as a vestibular dysfunction or other neurological issues. It is not solely associated with intoxication or other factors like high blood pressure or fatigue. Recognizing resting nystagmus as a sign of a possible medical condition is crucial, as it may require further investigation beyond the scope of typical sobriety assessments. This understanding is essential for law enforcement and medical personnel to ensure proper evaluation and care of the individual exhibiting these symptoms.
