CANAS LUCENDO, Manuel; PEREA BARTOLOME, María Victoria  and  LADERA FERNANDEZ, Valentina. Relationship Between Executive Functions and Neuropsychiatric Disorders in Patients with Alzheimer‘s Disease of Different Degrees of Severity. Av. Psicol. Latinoam. [online]. 2022, vol.40, n.3, 3.  Epub July 04, 2023. ISSN 1794-4724.  https://doi.org/10.12804/revistas.urosario.edu.co/apl/a.10249.

The aim of the study was to investigate executive functions (EF) and neuropsychiatric disorders (ND) in patients with Alzheimer's disease (AD) according to the degree of severity, compared to subjects without cognitive impairment (SWCI). Fifty patients with AD and 60 SWCI were studied in a non-experimental-cross-sectional study with non-probabilistic sampling based on a series of inclusion criteria. The frontal evaluation battery and the neuropsychiatric inventory were applied and the results showed that there is a negative relationship of moderate intensity between EF and ND, regardless of the degree of severity of AD. It can be concluded that, in the mild phase, euphoria is related both to sensitivity towards interference and to inhibitory control; in moderate phase irritability is positively related to sensitivity towards interference; and in the moderately severe phase, motor programming is negatively related to agitation.

Keywords : Alzheimer's disease; executive function; neuropsychiatric disorders.
