ABSTRACT

PURPOSE: Obstructive sleep apnea syndrome is a clinical sleep disorder defined by total or partial airflow restraint during sleep that results in fragmented sleep and hypoxemia, impacting negatively with cognitive functioning. This review was conducted on studies investigating structural brain alteration and cognitive impairment in obstructive sleep apnea syndrome. METHOD: We searched on PubMed databases and screening references of included studies and review articles for additional citations. From initial 190 publications, only 17 met search criteria and described the cognitive impairment in obstructive sleep apnea syndrome. RESULTS: Findings showed that patients with this syndrome had worse performance than healthy controls in attention, memory, and executive functions, showing specific neuroanathomical features. Cognitive impairment is also related to the severity of pathology. Treatment could improve certain cognitive aspects. CONCLUSIONS: Cognitive deficits seem to be mainly attributable to decreased daytime vigilance and nocturnal hypoxemia.

ABSTRACT

Purpose of the study: Pantothenate Kinase-associated Neurodegeneration (PKAN) is a form of Neurodegeneration with brain iron accumulation (NBIA) due to gene mutations. Classical phenotype showed progressive neurological symptoms associated to a characteristic pattern of basal ganglia iron deposits. The atypical case, with adult-onset manifestation, could have neuropsychiatric symptoms with behavioral deficits. We described an adult-onset case of Pantothenate Kinase-associated Neurodegeneration.Materials and methods: The patient underwent neuropsychological and psychiatric evaluation and Magnetic Resonance Imaging, respectively for cognitive and behavioral assessment and to confirm the characteristic findings of this syndrome.Results: The patient showed atypical phenotype of Pantothenate Kinase-associated Neurodegeneration, characterized by language deficits, dixesecutive, and psychiatric manifestations, such as obsessive ideation, impulsivity, and disinhibition.Conclusions: This description could be helpful to a more correct diagnosis and clinical management.
