Neonatal Encephalopathy Diagnosis: 5 Tests For Infant Brain Health

Neonatal encephalopathy refers to a condition in newborns characterized by brain dysfunction. It is Caused by oxygen deprivation, infections, maternal health conditions, genetics, and traumatic birth events. Symptoms include breathing difficulties, seizures, feeding problems, and altered consciousness. Neonatal encephalopathy diagnosis involves clinical evaluation, neurological exams, blood tests, brain imaging, and EEG.

Result Value	Genetic variants, mutations, or risk factors
Normal Value	Depends on genetic test
Accuracy	Precise genetic analysis
Interpretation	Analysis and interpretation of genetic test results

Genetic testing (DNA testing) identifies genetic abnormalities or mutations in neonates with encephalopathy, aiding accurate Neonatal encephalopathy diagnosis and interpretation of test results.

 

4. Electroencephalogram (EEG)

• In Neonatal encephalopathy test, Detects abnormal brain patterns.
• Aids in Neonatal encephalopathy diagnosis and monitoring conditions.
• Guides treatment decisions for optimal care.

Electroencephalogram (EEG)	Details
Also Known As	Brainwave test
Purpose	Measure and record electrical activity in brain
Sample	None
Preparation	Clean hair, Medication Avoidance
Procedure	Scalp Electrode Placement, Brainwave Capture
Test Timing	30-60 minutes
Test Price (INR)	1,000-5,000
Result Value	Analysis of brainwave activity
Normal Value	Presence of normal brainwave patterns
Accuracy	Detects brain abnormalities
Interpretation	Expert interpretation of EEG findings to determine brain activity

Electroencephalogram (EEG), also known as a brainwave test, measures and records electrical activity in the brain to detect abnormalities. By visualizing brainwave patterns, it aids in accurate interpretation of brain activity and identification of potential abnormalities.

 

5. Lumbar Puncture

• In Neonatal encephalopathy test, Detects abnormal brain patterns.
• Aids in diagnosing and monitoring neurological conditions.
• Guides treatment decisions for optimal care.

Lumbar Puncture	Details
Also Known As	Spinal tap
Purpose	CSF Analysis
Sample	Cerebrospinal fluid
Preparation	Special Instructions, Healthcare Guidelines
Procedure	CSF Withdrawal
Test Timing	10-30 minutes
Test Price (INR)	1,000-5,000
Result Value	Analysis of cerebrospinal fluid
Normal Value	Infection Absence
Accuracy	Accurate CSF analysis
Interpretation	Professional CSF Analysis for Neonatal encephalopathy Diagnosis

Lumbar puncture, also known as a spinal tap, collects cerebrospinal fluid for analysis to diagnose infections or other neurological conditions. By examining the fluid, it provides valuable insights for accurate interpretation and identification of potential abnormalities or infections.

 

Neonatal Encephalopathy Tests Overview

*Test Price, range and timing may vary as per location, lab type, and procedure.

Brain imaging, hearing screening, and genetic testing are diagnostic procedures used to visualize and assess the brain, detect hearing loss, and identify genetic variations/disorders. These tests provide valuable insights for Neonatal encephalopathy diagnosis and treatment.

 

Neonatal Encephalopathy Differential Diagnosis

Similar Disease	Differentiating Factors
Hypoxic-ischemic encephalopathy (HIE)	Presence of perinatal asphyxia, abnormal Apgar scores, evidence of placental insufficiency
Inborn errors of metabolism	Specific metabolic markers or genetic testing, abnormal biochemical profiles, family history of metabolic disorders
Neonatal seizures	Electroencephalogram (EEG) findings, distinct seizure patterns, response to antiepileptic medications

Neonatal encephalopathy can be differentiated from hypoxic-ischemic encephalopathy by perinatal asphyxia indicators, while inborn errors of metabolism require metabolic markers and genetic testing for Neonatal encephalopathy diagnosis. Neonatal seizures are distinguished by EEG findings and response to antiepileptic medications.
