Final answer:
A neurologist is the specialist who treats conditions related to the brain, handling disorders like epilepsy, stroke, and Parkinson's disease, and using diagnostic tools such as EEG and CT scans.
Step-by-step explanation:
The specialist who treats conditions related to the brain is a neurologist. Neurologists are highly trained medical doctors who specialize in diagnosing and treating disorders of the nervous system, which includes the brain, spinal cord, and nerves. Conditions that neurologists manage include epilepsy, stroke, dementia, nervous system injuries, Parkinson's disease, sleep disorders, and multiple sclerosis. After completing college and medical school, they undergo three to four years of neurology residency to become experts in their field. Neurologists can employ a variety of diagnostic tools such as electroencephalography (EEG) to record brain activity and computerized tomography (CT) scans to detect abnormalities within the brain. Treatment for neurological conditions often involves prescribing medications, or in some cases, referring patients to a neurosurgeon for surgery.
