ABSTRACT Artículo en español English version
INTRODUCTION Mild cognitive impairment (MCI) is defined as an abnormality in cognitive function not provoking a noticeable disability in activities of daily living in the affected person. In a group of patients with MCI, we propose to observe and to quantify the presence of behavioral disorders, using the neuropsychiatric inventory (NPI).

PATIENTS AND METHODS NPI is a known instrument in evaluation of this kind of disorders in patients with dementia, and it is a semi structured interview with a relevant informer or relative to the patient. NPI was applied to a series of 100 cases (61 women and 39 men) of MCI, diagnosed as usual in our settings. Mean age was 74.3 ± 10 years, and mean MEC (Spanish modified version of MMSE) 25.57 ± 4.2 (over a maximum of 35 points).

RESULTS Most prevalent disorder was depression, in 36 % of cases, and other frequent findings were irritability (35%), anxiety (24%) and apathy (19%). In some cases, agitation (4%), abnormal motor behavior (3%) and delusions (1%) were detected. Hallucination, desinhibition and euphoria or elation were not detected in this series. CONCLUSION. Data show a certain similarity with occidental culture environment, globally considered. The presence of behavioral and psychological disorders in patients with MCI could be a marker for later development of dementia. NPI can be a usable tool when detection and evaluation of these symptoms is required.
