Objectives: The purpose of this study was to assess the occurrence of stres
sful life events in the year before the onset of neurocirculatory asthenia.
Design: Case-control retrospective study
Setting: A university medical outpatient clinic,
Subjects: A consecutive series of 50 patients with neurocirculatory astheni
a and a control group of 50 healthy subjects, matched for sociodemographic
variables, were studied.
Main outcome measures: Paykel's interview for Recent Life Events (a semistr
uctured research interview covering 64 life events) was administered to pat
ients and controls.
Results: Patients with neurocirculatory asthenia reported significantly mor
e stressful life events than the control group (P < 0.05) and had significa
ntly more of the following: exits (P < 0.05), undesirable (P < 0.05) and un
controlled (P < 0.01) events. More events that had an objective negative im
pact (P < 0.091) and more independent events (P = 0.07) were also reported,
Ratings of impact and independence were carried out by a blind rater who w
as unaware whether the event had occurred in patients or controls.
Conclusions: The results are suggestive of a strong relationship between st
ressful life events and neurocirculatory asthenia, This is in agreement wit
h a multifactorial model of pathogenesis in neurocirculatory asthenia and w
ith current understanding of the extensive links of behavioral responses to
stress with neurophysiological and biochemical processes.
