Abstract
Psychiatric disorders are present in dementia (Cognitive damage) and they are part of the psychological and behavioral dementias (SPCD), which are present in almost every patient and a very important cause for psychogeriatric patients´admission. Methodology: Cognitive damage was analysed (MEC de Lobo, Pfeiffer test and semantic and verbal fluency) and functional abilities in elderly inpatients, who were older than 65 years old, were also analysed (Barthel test) for 3 months. Relating these to the different sociodemographic variables. Results: Half of the 18 patients who were analyzed and studied, had any type of depressive symptoms and between 22-44% showed some signs of cognitive damage according to the test used to sieve. Discussion/Conclusions: Psychiatric disorders measured with NPI are directly related to the disability degree for AVD´s and at the same time, this is related to the admission span. The different percentages which affect cognitive damage according to the test used, shows the importance of the correct test´s choice depending on the studied population and the type of analysis accomplished.
