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 Objective to verify if cognitive impairment can affect the total score obtained on the Freezing of Gait score ( FOG - score ) test in patients with Parkinson's disease ( PD ) . Material and method A sectional , correlational non - exploratory study was carried out on thirty - four subjects , with mild to moderate PD disease . The participants carried out the FOG - score test and cognitive evaluation : the Mini - Mental State Examination ( MMSE ) , the Frontal Assessment Battery ( FAB ) and the Fuld Object Memory Evaluation ( FOME ) . Motor function was assessed by the motor subscale of Unified Parkinson's Disease Rating Scale ( UPDRS )  ( part III ) . Results there was a significant negative correlation between the FOG - score test and global cognition ( MMSE )  ( r = .68 ; p < .001 ) , memory - related parameters ( FOME )  ( r = .64 ; _P_ < .001 ) and executive functions ( FAB )  ( r = .57 ; _P_ < .001 ) . The motor scores held lower relation with FOG parameters ( r = .35 ; _P_ > .005 ) . Conclusions the results of this study suggest that cognitive impairment can strongly affect task performance of the FOG - score test . This suggests the need to adjust the cut - off point when assessing PD patients suffering from cognitive dysfunction . This could prevent the examiner from overestimating the existence and recurrence of freezing episodes in this population .
