Which of the following is considered an abnormal neurological finding?

Abnormal deep tendon reflexes are a critical neurological finding that can indicate a range of underlying conditions. Deep tendon reflexes are involuntary responses that occur when tendons are tapped, usually in a laboratory or clinical setting, and are used to assess the integrity of the nervous system. In a healthy individual, these reflexes are typically brisk and consistent. However, when deep tendon reflexes are classified as abnormal—being either diminished or exaggerated—it may suggest issues such as neuropathy, spinal cord problems, or other neurological disorders. This abnormal finding prompts further investigation to identify the cause of the neurological deficit and to guide assessment and management.

Normal speech, being alert and oriented, and a normal gag reflex represent standard neurological findings. Each of these indicates that the patient's brain function and cranial nerve integrity are operating within expected parameters, which is why they would not be deemed abnormal in a neurological evaluation.
