Abstract
Objective
Superficial siderosis (SS) is a neurodegenerative condition due to the long-term effects of hemosiderin deposition on the surface of the brain, cerebellum, brainstem, and spinal cord. SS symptoms include sensorineural hearing loss, ataxia and upper motor
neuron signs. SS was diagnostically evasive until magnetic resonance imaging (MRI) became available. As the detection of SS improved, case studies have become more prevalent. To our knowledge, however, this is the first report of SS detailing a
comprehensive neuropsychological assessment.
Method
The current study presents a right-handed female in her early 60s, with a university level of education, who was diagnosed with SS.
Results
Her neuropsychological profile showed impairment across multiple domains, including memory and executive function, with consistent behavioral findings. The results from a comprehensive neuropsychological assessment include dementia and a cerebellar
cognitive affective syndrome.
Conclusions
Neuropsychological evaluation of a patient with new cognitive impairment in combination with unexplained hearing loss, gait disorder, or myelopathy should lead to a referral for MRI that includes techniques sensitive for iron deposition, in order to rule
out SS.
