Hidden Impairments During Subarachnoid Haemorrhage Recovery, Description and Evolution of a Newly Described Syndrom

Every year, subarachnoid hemorrhage affects 9.1 people per 100,000 worldwide, with a peak between the ages of 50 and 60. Its frequency and relatively young age of onset make it a major source of decline in healthy life years.

Progress over the past thirty years has led to a 57% reduction in mortality, but these figures do not always reflect the day-to-day reality of these patients, for whom recovery remains incomplete in almost half of cases. For example, a third of patients have not returned to work at one year, and of those who have, only half have returned to work full-time. In 2020, a Norwegian team showed that, at one year, a third of patients suffer from a "post-HSA syndrome", as yet little described, but which seems very similar to the post-concussion syndrome experienced by patients after head trauma. In their study, only 3% of patients with this syndrome returned to work at one year. A better understanding of the incidence of this syndrome, as well as its evolution and determinants, is therefore essential.

With this in mind, the investigators chose to assess the presence of post-SAH syndrome at 3 months and its repercussions on return to work, using the Rivermead questionnaire.

Secondly, in view of the prevalence of post-traumatic stress syndrome at 3 years (a quarter of patients), the investigators wished to study the factors determining the presence of post-HSA syndrome and an inability to return to work at 3 months, 6 months, 1 year.
