G31.82
Leigh's disease
Clinical Classification Guidelines
Inclusion Terms
- Subacute necrotizing encephalopathy
Medical Intelligence & Overview
Leigh's disease, also known as subacute necrotizing encephalopathy, is an uncommon, inherited neurological disorder that affects the central nervous system. It usually manifests in infancy or early childhood, leading to progressive loss of mental and physical abilities. The disease causes degeneration of certain parts of the brain, which results in severe neurological impairments. Understanding this condition can help in recognizing symptoms early and exploring potential management strategies.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting mitochondrial function Inherited abnormalities passed from parents Disruptions in cellular energy production within nerve cells
Key Symptoms: Progressive neurological decline Muscle weakness and hypotonia (reduced muscle tone) Seizures Difficulty with coordination and balance Loss of developmental milestones such as sitting, standing, or walking Poor feeding and irritability in infants Lack of muscle control leading to movement difficulties Respiratory problems as the disease advances
Diagnostic & Treatment
Diagnosis Path: Neuroimaging scans such as MRI to observe characteristic brain changes Blood and urine tests to check for elevated lactate and pyruvate levels Genetic testing to identify mitochondrial DNA mutations Muscle biopsies to examine cellular abnormalities Metabolic studies to assess energy production issues
Treatment Protocols: Supportive care with nutritional support and feeding assistance Medications to control seizures Physical, occupational, and speech therapies to maintain mobility and communication Supplements such as vitamins and cofactors aimed at mitochondrial function Managing infections and other secondary complications promptly
