Overview
Differentiating Friedreich’s ataxia from other Diseases
As Friedreich’s ataxia manifests in a variety of clinical forms and different ages, differentiation must be established in accordance with the manifestations of the disease and onset of the symptoms.
The main and most prominent symptom of the Friedreich’s ataxia is ataxia that worsens over time and it must be differentiated from other diseases that cause progressive ataxia such as:
- Spinocerebellar ataxias (SCA)
- Dentato-rubro-pallido-luysian atrophy
- Episodic ataxia
- Spastic ataxia
- Abetalipoproteinemia
- Refsum disease
- Hypomyelinating leukoencephalopathy: Hypomyelination, basal ganglia atrophy, rigidity, dystonia, chorea
- Pure cerebellar ataxia: Other family members of these patients may have frontotemporal dementia or motor neuron disease
- Progressive cerebellar atrophy with epileptic encephalopathy: Infantile seizures, intellectual deficits, microcephaly
- Rapid-onset ataxia: Cerebellar atrophy
- CAPOS mutation: (Cerebellar ataxia, areflexia, Pes cavus, optic atrophy, sensorineural hearing loss, and alternating hemiplegia)
