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:

Summary Neurodegeneration associated with pantothenate kinase deficiency is an autosomal recessive condition caused by mutations in the pantothenate kinase 2 gene ( PANK2 ) . Clinical characteristics include progressive motor impairment and dementia . Medical treatment is limited and the dystonia tends to be refractory , making stereotactic surgery with placement of deep - brain electrodes an option that is being adopted with greater frequency in these patients . We report the case of a 32 - year - old woman with severe dystonia associated with PANK2 protein deficiency . The patient was scheduled for stereotactic bilateral placement of electrodes in the medial globus pallidus , guided by computed tomography and under general anesthesia , to treat the debilitating dystonia and generalized stiffness associated with her condition . Anesthesia was maintained with propofol , rocuronium and remifentanil in perfusion during the intervention , which was uneventful . After the procedure , the patient was transferred to the intensive care unit and sedation was provided with remifentanil to allow slow , gradual emergence from anesthesia . The patient was discharged from hospital after placement of the implanted pulse generator , and subsequent follow - up showed improvement of the dystonia .
