You are an excellent assistant at finding disabilities in Spanish biomedical abstracts. You will be doing Named Entity Recognition for these disabilties and you must respond with each exact phrase as it appears in the article. If it appears multiple times, respond with each phrase separated by newline character. If there are no disabilities, respond with NA.

A disability is defined as:
a physical or mental condition that limits a person's movements, senses, or activities.


Abstract:

Abstract Introduction Creutzfeldt - Jakob disease ( CJD ) is a transmissible spongiform encephalopathy due to the accumulation of altered prion protein isoform ( PrPsc ) in the brain . The typical clinical symptoms are rapidly progressive dementia , ataxia , myoclonus , electroencephalogram ( EEG ) alterations , with positive 14 - 3 - 3 protein in cerebrospinal fluid and changes in magnetic resonance imaging ( MRI ) . The definitive diagnosis is done anatomopathologically . Case report A 64 year old female patient who presented with rapid progressive ataxia , visual disturbances , dysarthria , dysdiadochokinesia , dysmetria and axial dystonia . She also presented with apraxia , atrophy , myoclonus and seizures . She died 4 months after onset , with severe motor deterioration , rigidity , flexed posture and low cognitive - behavioral impairment . We did an anatomopathological study in addition to molecular biology . Conclusions We present a “defined” case study of ECJ with infrequent symptoms of ataxia , myoclonus , but with no cognitive deterioration for its genotype ( M/V1 ) . Despite inconclusive 14 - 3 - 3 protein levels and atypical EEG , our diagnosis was mainly guided by the rapid onset of symptoms , in which high - field MRI ( with the appropriate sequences ) were key in showing typical images and in defining the diagnosis .
