Emergency situations related to mental disorders represent a significant proportion of all medical emergencies. Over the last years we have been witness to an upturn in the incidence of psychiatry emergency service because to change of mood.

To determine the profile of the patient who requires psychiatric attention with changing of mood in our area in different seasons.

This is a prevalence and prospective study in which the dependent variable is taken as change of mood and we also use three more independent variables that are age sex and seasonality. The seasonality (spring period and summer period) will be at the same time the form of divided the population in two groups to compare.

Out of all the consultations for changing of mood in the emergency service during the first period (113 patients), 34% were men and 66% were women. The age range of 36–50 years was more frequent for women and the age range of 51–65 years was more frequent for men.in the second period (with 162 patients), 137 women (86%) and 25 men (14%).in this case, the most common age range was 36–50 years, both for women and for men.

The epidemiological and clinical characteristics of patients with changing of mood assessed by the emergency service are described from a naturalistic approach.

Which Chi2 we will discover if the population who has been taken between woman and man is significant and with the median, we will also determine if the age ranges are enough significant to confirm our hypothesis.
