About this study
Descriptive observational study in patients with spontaneous subarachnoid hemorrhage or following aneurysmal rupture to assess the presence of a post-HSA syndrome at 3 months, 6 months and 1 year, and its impact on functional outcome using the Rivermead questionnaire
Read the detailed description
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluate the presence of post SAH syndrome at 3 months and its impact on return to work using the Rivermead Post-Concussion symptoms questionnaire (RPQ), and its impact on functional outcome.
The Rivermead questionnaire is a 16-item self-administered questionnaire, rated from 0 to 4, giving a total of 0 to 52 points.
This scale was created to assess post-concussion syndrome, which in many ways is similar to what patients experience after a SAH.
The higher the score, the greater the difficulties experienced by the patient. A score of 3 or 4 for any of the responses indicates that the patient is incapacitated.
Measured: 3 months
Secondary outcomes (3)
- study the factors determining the presence of a post-HSA syndrome and an inability to return to work at 3 months, 6 months and 1 year
Quality of life assessed using the SS-QoL questionnaire, specific to stroke patients. Self-questionnaire with 49 questions covering 12 domains (including work/productivity, mood, social roles, family roles, personality).
Measured: 3 months, 6 months and 1 year,
To study the prevalence of post-traumatic stress in this population
Assess the prevalence of post-traumatic stress in this population using the PCL-5 self-questionnaire. PCL-5 is a 20-question self-questionnaire.
Measured: 3 months, 6 months and 1 year,
Study patients' coping strategies in relation to functional recovery using the Brief-Cope self-questionnaire

Primary outcome
Evaluate the presence of post SAH syndrome at 3 months and its impact on return to work using the Rivermead Post-Concussion symptoms questionnaire (RPQ), and its impact on functional outcome.
Time frame: 3 months
The Rivermead questionnaire is a 16-item self-administered questionnaire, rated from 0 to 4, giving a total of 0 to 52 points. This scale was created to assess post-concussion syndrome, which in many ways is similar to what patients experience after a SAH. The higher the score, the greater the difficulties experienced by the patient. A score of 3 or 4 for any of the responses indicates that the patient is incapacitated.
3 secondary outcomes
- study the factors determining the presence of a post-HSA syndrome and an inability to return to work at 3 months, 6 months and 1 year
Time frame: 3 months, 6 months and 1 year,
To study the prevalence of post-traumatic stress in this population
Time frame: 3 months, 6 months and 1 year,
Study patients' coping strategies in relation to functional recovery using the Brief-Cope self-questionnaire
Time frame: 3 months, 6 months and 1 year,
Results and safety
The study was withdrawn before enrolling participants, so there are no results.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Apr 2026; AzTrials last refreshed its copy on 7 Nov 2026.
