Focal neurologic signs (/ˈfoʊkəl nʊˈrɑːlədʒɪk saɪnz/), also known as focal neurological deficits or focal CNS signs, are abnormalities in nerve, spinal cord, or brain function that are localized to a specific area of the body. The term is derived from the Latin focus meaning "fireplace, hearth" and the Greek νεῦρον (neûron) meaning "nerve" and λογία (logía) meaning "study of".

Causes
Focal neurologic signs can be caused by a variety of conditions that affect the CNS, including stroke, brain tumor, multiple sclerosis, and traumatic brain injury.
Diagnosis
Diagnosis of focal neurologic signs typically involves a thorough medical history and physical examination, as well as imaging studies such as MRI or CT scans. Further diagnostic tests may be required depending on the suspected underlying cause.
Treatment
Treatment for focal neurologic signs is aimed at addressing the underlying cause. This may involve medication, surgery, or other interventions such as physical therapy or occupational therapy.
