Acute movement disorders in children: experience from a developing country.

Area of Science:

• Pediatrics
• Neurology
• Movement Disorders

Background:

• Acute movement disorders present a diagnostic challenge in children.
• Understanding the etiology and clinical spectrum is crucial for timely intervention.

Purpose of the Study:

• To characterize the types and causes of acute movement disorders in pediatric patients.
• To identify common etiologies for different hyperkinetic and hypokinetic movement disorders.

Main Methods:

• Retrospective analysis of 92 children diagnosed with acute movement disorders.
• Data collected from a tertiary hospital in India.
• Classification of disorders based on clinical presentation and etiology (inflammatory vs. non-inflammatory).

Main Results:

• Hyperkinetic movement disorders (89/92) were predominant, including myoclonus (25), dystonia (21), choreoathetosis (19), and tremors (15).
• Vitamin B12 deficiency (13 infants) was the leading cause of tremors; rheumatic fever and encephalitis were common for choreoathetosis.
• Non-inflammatory causes (60) were more frequent than inflammatory (32).

Conclusions:

• Hyperkinetic movement disorders are the most common presentation in children with acute movement disorders.
• Diverse etiologies, including nutritional deficiencies and infections, underlie these conditions.
• Further research is needed to understand underreported psychogenic movement disorders.
