What is Difference Between Neurology and Neurosurgery?

Neurology and Neurosurgery are overlapping medical specialties focusing on the nervous system,

including the brain, spinal cord, and nerves. However, while neurology concentrates more on

diagnosing and treating neurological conditions through medication, therapy or other nonsurgical

approaches, neurosurgery involves direct surgical intervention to treat disorders of the nervous

system.

What Is Neurology?
Neurology is a branch of medicine dealing with disorders of the nervous system, including the brain,

spinal cord, and nerves. Neurologists diagnose and treat diseases related to the nervous system.

Their focus is on determining what neurological conditions a patient is experiencing through

comprehensive exams, diagnostic testing, and identification of symptoms.

Once a neurological disorder has been diagnosed, neurologists determine an appropriate treatment

plan which may include medication, physiotherapy, nerve stimulation therapy, lifestyle changes, and

managing chronic conditions. Some common neurological conditions that neurologists treat include

epilepsy, stroke, Alzheimer’s disease, headaches, sleep disorders, multiple sclerosis, Parkinson’s

disease, and more.

Doctors who specialize in neurology are known as neurologists. Becoming a neurologist requires an

extensive amount of education and training including medical school, residency, internships, and

licensing. Neurologists have expertise in the intricate workings of nerves, brain, spinal cord, and how

to medically manage associated diseases.

What Is Neurosurgery?
Neurosurgery is a surgical specialty focused on treating disorders of the brain, spine, spinal cord, and

peripheral nerves through operations. Neurosurgeons perform surgeries to repair damage from

injury or illness related to the nervous system. They operate on the brain, spine, or other areas to

remove tumours, repair blood vessel abnormalities like aneurysms, drain blood clots, relieve nerve

compression, treat head trauma or spine injuries, and more.

Neurosurgeons perform minimally invasive endoscopic procedures when possible or open surgeries

when needed. Techniques involve using lasers, ultrasound, robotic navigation and computer

systems. Implanting neural stimulator devices, catheters, or computer-assisted devices may also be

part of the treatment.

Becoming a neurosurgeon involves lengthy residencies learning the complexities and specialized

techniques of neurological surgery. This includes evaluating patients through examinations,

diagnostic imaging, and interpreting tests. Determining optimal surgical treatments requires this

advanced expertise.

How Neurology and Neurosurgery Are Different

While neurology and neurosurgery both focus on the nervous system, there are key differences in

their approaches:

Neurologists diagnose neurological conditions and manage patients through medication, therapy

and other nonsurgical treatments. Neurosurgeons directly operate on the brain, spine or other parts

of the nervous system to surgically treat neurological disorders.

Neurologists rely on examinations and tests like EEG, EMG, nerve conduction studies, and sleep

studies to determine what neurological conditions a patient has. Neurosurgeons evaluate patients

through clinical examinations and diagnostic imaging like CT scans and MRIs to determine if surgical

intervention is needed.

Neurologists often treat conditions like stroke, epilepsy, headaches, multiple sclerosis, Parkinson’s,

Alzheimer’s, and more with medications and therapies. Neurosurgeons operate to remove brain

tumors, repair aneurysms, remove blood clots, repair herniated discs, and treat head or spine

injuries.

When nonsurgical treatments done by a neurologist are ineffective for neurological issues, they may

refer a patient to a neurosurgeon to be evaluated for potential surgery. Neurologists and

neurosurgeons work together before and after surgeries to manage patient care.

Both specialize in the nervous system but neurology is more of a clinical medical specialty while

neurosurgery is focused on surgical treatment. Neurologists prescribe medications and therapies,

while neurosurgeons directly operate on the brain or nerves.

There is some overlap with certain conditions. For example, with epilepsy neurologists manage

medications while neurosurgeons may operate to remove seizure-causing brain tissue if needed.

What are Common Neurological Conditions?
: Caused by disrupted blood flow to the brain, leading to various symptoms depending on the

affected area.

Alzheimer’s Disease

Some common conditions treated by neurologists and neurosurgeons include:

Stroke –Disruption of blood supply to the brain

Multiple sclerosis –Central nervous system disease

Epilepsy –Seizures and convulsions

Alzheimer’s disease –Progressive dementia

Parkinson’s disease –Movement disorder

Aneurysms –Artery wall bulges

Brain tumors –Intracranial neoplasms

Headaches and migraines –Severe head pain

Peripheral neuropathy –Nerve damage in extremities

Spinal cord injuries –Vertebral column trauma

Neuroinfectious diseases –Infections affecting the nervous system

Brain damagefrom hypoxia, illness or trauma.

Headaches and migraines -Severe head pain

What are the Treatment Options Available for the Neurological Disorders?


Treatment options that may be used for neurological conditions include:

• Medications like immune-modifying drugs, antiseizure medicines, chemotherapy, and pain relievers
• Surgical procedures such as tumor removal, aneurysm clipping, draining blood clots or abscesses, and biopsies
• Implanted devices like deep brain or vagus nerve stimulation
• Physical, occupational and speech therapy
• Endovascular procedures such as coiling, stenting, or angioplasty
• Ventriculostomy to treat hydrocephalus
• Neurorehabilitation to relearn skills and manage disabilities
• Psychotherapy and psychiatric medications
• Nutritional therapy for conditions like epilepsy or Alzheimer’s
• Complementary approaches like massage, acupuncture and yoga
• Lifestyle adjustments to manage neurological impairments

In conclusion, neurology and neurosurgery are complementary medical fields, each specializing in

distinct aspects of nervous system disorders. Whether you need the expertise of a neurologist or a

neurosurgeon depends on the nature of your condition. Consulting with your primary care physician

is often the first step in determining which specialist is best suited to address your neurological

concerns. If in doubt, don’t hesitate to seek their guidance.
