Metabolic and genetic disorders mimicking cerebral palsy

Area of Science:

• Neurology
• Genetics
• Metabolic Disorders

Background:

• Cerebral palsy (CP) is a group of movement and posture disorders from early brain lesions.
• Metabolic and genetic conditions can present symptoms similar to CP, especially in early childhood.
• Distinguishing CP from these mimics is vital for appropriate management.

Purpose of the Study:

• To identify clinical features suggesting non-CP disorders.
• To outline red flags in clinical presentation and neuroimaging.
• To highlight specific metabolic and genetic conditions mimicking CP.

Main Methods:

• Literature review focusing on clinical presentations and diagnostic criteria.
• Analysis of case studies and reviews on differential diagnoses for CP.
• Synthesis of information on red flags and specific mimicking conditions.

Main Results:

• Several clinical and neuroimaging findings can indicate an underlying metabolic or genetic disorder.
• Conditions like inherited metabolic diseases and genetic syndromes may present with spasticity, ataxia, or dyskinesia.
• Early identification of these mimics is possible through careful evaluation of specific signs.

Conclusions:

• Prompt recognition of red flags can differentiate CP from mimicking genetic and metabolic disorders.
• Accurate diagnosis of these mimics is essential for targeted treatment, prognosis, and genetic counseling.
• This review provides a guide for clinicians to suspect and investigate alternative diagnoses in suspected CP cases.
