A neurological assessment is one of the most important clinical tools used to understand how well a patient’s brain, spinal cord, and nerves are functioning. Whether a patient comes in with weakness, headaches, numbness, dizziness, confusion, or after an injury, neurologists and emergency doctors rely on a structured neurological examination to diagnose problems early.

At Sai Hospital, Haldwani, our neurology team performs comprehensive neurological assessments to detect stroke, neuropathy, seizures, infections, and other serious conditions — often within minutes of a patient’s arrival. This guide explains how to perform a neurological assessment, step by step, in a clear and practical way.

What Is a Neurological Assessment?

A neurological assessment is a systematic evaluation of the nervous system.
It checks:

• Brain function
• Cranial nerves
• Motor strength
• Sensation
• Reflexes
• Coordination
• Gait
• Mental status

It helps identify the location, severity, and nature of neurological dysfunction.

How to Perform a Neurological Assessment (Step-by-Step)

A proper neurological exam has seven major components. Each gives essential information about how the nervous system is working.

1. Mental Status Examination

This assesses the patient’s cognitive function.

Check for:

• Level of consciousness (alert, drowsy, confused)
• Orientation (name, place, time)
• Memory (short-term & long-term)
• Attention (simple tasks like spelling backward)
• Language (fluency, repetition, comprehension)
• Judgment and reasoning

A patient who is confused, disoriented, or unable to follow commands may have issues such as infection, stroke, metabolic imbalance, or head injury.

2. Cranial Nerve Examination

There are 12 cranial nerves, each controlling specific functions such as smell, vision, facial movement, and swallowing.

Key checks include:

• CN II (Optic): Vision, visual fields
• CN III, IV, VI: Eye movements and pupil reaction
• CN V: Facial sensation, jaw strength
• CN VII: Facial expressions (smile, frown, puff cheeks)
• CN VIII: Hearing
• CN IX, X: Gag reflex, swallowing
• CN XI: Shoulder shrug
• CN XII: Tongue movement

Abnormalities help locate lesions in the brainstem or specific nerve pathways.

3. Motor System Examination

This checks muscle strength, tone, and bulk.

Assess:

• Muscle power on both sides
• Muscle tone (rigid, spastic, or floppy)
• Fasciculations (involuntary twitching)
• Muscle wasting

Strength is graded using the Medical Research Council (MRC) Scale from 0 to 5:

• 0 = no movement
• 5 = normal strength

Weakness on one side may indicate stroke, while generalized weakness may suggest neuropathy or muscle disease.

4. Sensory System Examination

The sensory exam evaluates how well nerves carry information from the body to the brain.

Check for:

• Light touch
• Pain (pinprick)
• Temperature
• Vibration (using tuning fork)
• Proprioception (joint position sense)

Patterns of sensory loss help differentiate:

• Peripheral nerve damage
• Spinal cord lesions
• Stroke-related sensory deficits

5. Reflexes

Reflex testing helps identify problems in the spinal cord or peripheral nerves.

Common reflexes tested:

• Knee jerk
• Ankle jerk
• Biceps reflex
• Triceps reflex

Reflexes are graded from 0 to 4+

• 0 = absent
• 2+ = normal
• 4+ = hyperactive

Hyperactive reflexes may suggest spinal cord injury or brain lesions, while absent reflexes may indicate nerve damage or neuropathy.

6. Coordination Testing

Coordination depends on cerebellum function. Problems here cause imbalance and clumsiness.

Tests include:

• Finger-to-nose test
• Heel-to-shin test
• Rapid alternating hand movements
• Checking for tremors or involuntary movements

Abnormal coordination may indicate:

• Cerebellar lesions
• Alcohol intoxication
• Tumors
• Degenerative diseases

7. Gait and Balance Assessment

Observing how a person walks provides valuable neurological information.

Check for:

• Normal walking
• Heel-to-toe (tandem) walking
• Standing with feet together (Romberg test)
• Arm swing, stride length, balance

Abnormal gait may signal:

• Stroke
• Parkinson’s disease
• Neuropathy
• Cerebellar disorders
• Spinal cord issues

Why a Neurological Assessment Is Important

A neurological exam helps doctors:

• Identify stroke within minutes
• Detect early signs of brain infection
• Diagnose nerve compression or neuropathy
• Confirm seizure-related changes
• Decide if imaging (CT/MRI) is needed
• Monitor disease progression

In emergencies — especially stroke — early neurological assessment can save brain tissue and prevent disability.

When Should a Neurological Assessment Be Done?

You should seek neurological evaluation if you experience:

• Sudden weakness or numbness
• Severe headaches
• Vision changes
• Slurred speech
• Memory loss
• Loss of consciousness
• Difficulty walking or balancing
• Tremors or involuntary movements
• Seizures

At Sai Hospital, Haldwani, neurological assessment is performed as part of routine evaluation as well as emergency care.

How Long Does a Neurological Assessment Take?

A full neurological exam usually takes 15–30 minutes, depending on complexity.
Emergency assessments may be done rapidly in 3–5 minutes.

FAQs: How to Perform a Neurological Assessment

1. Who performs a neurological assessment?
Neurologists, physicians, emergency doctors, and trained nurses can perform it.

2. Is a neurological exam painful?
No. It involves simple tests of movement, sensation, reflexes, and cognition.

3. How does a doctor check reflexes?
Using a reflex hammer to tap specific tendons.

4. Do I need tests like MRI after a neurological exam?
Only if the exam shows abnormalities or if symptoms require imaging.

5. Can neurological assessments detect stroke?
Yes. Sudden weakness, facial drooping, or speech difficulty during the exam often indicates stroke.

Conclusion

So, how to perform a neurological assessment?
It involves checking mental status, cranial nerves, motor strength, sensation, reflexes, coordination, and gait to understand how the nervous system is functioning.

At Sai Hospital, Haldwani, our neurologists perform detailed neurological examinations to diagnose conditions early and plan treatment that is accurate, effective, and individualized.

If you or a loved one has any neurological symptoms, don’t delay — early evaluation protects brain and nerve health.
