Which cerebral artery and side are typically involved in neglect syndromes, and what are the key clinical features?

Neglect syndromes are most commonly associated with infarcts in the right middle cerebral artery (MCA) territory, particularly affecting the right parietal lobe. Key diagnostic features include a lack of awareness of the left side of the body and environment, often without accompanying motor deficits. Clinicians should be aware that neglect can be subtle and may be mistaken for confusion or inattention. A common pitfall is overlooking right-sided neglect, which is less frequent but can occur with left MCA strokes.
