Inclusion Criteria:

• Signed written informed consent
• > 18 years old
• Aneurysmal subarachnoid haemorrhage >12 months prior to the start of the study.
• Diagnosed with post SAH syndrome/fatigue at ≥12 months after their hemorrhage

• Post-menopausal or using adequate contraceptive measures

  • Female patients of childbearing potential using a highly efficient method of contraception (i.e. a method with a failure rate of less than 1% [e.g. sterilisation, hormone implants, hormone injections, some intrauterine devices, or vasectomy in partner])
  • Male patients agreeing to use condoms during the study and for 3 months after the end of the study/last dose of the investigational medicinal product, or male patients with a partner who is using a highly efficient method of contraception (as described above)

Exclusion Criteria:

• Residual symptoms following other pathologies than aSAH
• Not adequately treated hydrocephalus secondary to aSAH
• Diagnosed with epilepsy, neurodegenerative disease, cerebral paresis, tumor cerebri, cerebral arterio-venous malformations

• Active substance abuse (drug screen taken at baseline)
• Current pregnancy or breast-feeding, or intention to become pregnant within 3 months after the last dose
• Women of childbearing age not using contraceptives
• Pathologic ECG, as assessed by the investigator. Max QTc-time on ECG in excess of 480 ms or any of these conditions that can increase QT related incidences: long QT syndrome or family history of long QT syndrome, hypothyreoidism, hypocalcemia, significant potassium deviations, type 1 diabetes with prolonged QT, and cardiac insufficiency
• Abnormal laboratory values of such severity that participation in the study, in the opinion of the investigator, is questionable
• Patients who are so debilitated by their disease that they are not assumed to be able to perform the assessments or handle the instruments used for evaluation of effect and/or are not able to consent
• Patients that speak so poorly Norwegian that they are not able to answer the questionnaires or undergo neuropsychological testing
• Previous treatment with OSU6162
• Clinically significant liver disease which may prevent the patient from completing the study and/or an elevation in either total bilirubin, alkaline phosphatase, LDH, SGOT of >2 times the laboratory reference
• Clinically significant renal disease which may prevent the patient from completing the study and/or an elevation in serum creatinine of >1.5 times the laboratory reference.
• Any surgical or medical condition which, in the opinion of the investigator, might interfere with the absorption, distribution, metabolism or excretion of OSU6162
• Patients treated with Modiodal, Xyrem, Mirtazapine, Mianserin or metabolic enzyme inhibitors or inducers, or drugs with a narrow treatment window (e.g. warfarin, antiepileptics, cyclosporine) and individually modelled drugs such as lithium
• Use of drugs capable of inducing hepatic enzyme metabolism (e.g., barbiturates, rifampicin, carbamazepine, phenytoin, primidone) within 30 days prior to the start of the study (or 5 half-lives of the inducing agent, whichever is longer)
• Antipsychotic treatment
• Patients treated with "unstable therapies", i.e., treatments that have not been at the same dose for at least 6 weeks prior to inclusion in this study. The treatment must also remain unchanged during the study period. Insomnia medication and other PRN medications are allowed.
• Use of acute or chronic medications for other medical conditions are allowed based on the investigator's judgement. Occasional use of over-the-counter (OTC) medication is not allowed during the study or one month prior to inclusion.
