Depressive disorder after traumatic brain injury

Depression is very common following a traumatic brain injury (TBI), also called a head injury. Around 50% of people with a head injury will have some form of depression over the next 10 years. This is almost 10 times more common than the general public. There are two main symptoms of depression, a constant low mood and a loss of enjoyment in everyday life. Depression can affect relationships, jobs, education, financial hardship and unhealthy lifestyles like smoking and poor diets. People with depression following a traumatic brain injury tend to die earlier than the rest of the population and they are more likely to commit suicide.
Our patient and public involvement group (PPI) recognised the symptoms of depression and also mentioned others such as irritability, confusion, being very sensitive to noises and light. They agree that trying to prevent depression occurring in the first place is very important. The idea that antidepressants given early could stop depression in the first place after a traumatic brain injury was appealing. They said they would want to be given everything for the best chance of recovery. The aim of this study is to find out if a commonly used antidepressant called sertraline is better at preventing depression than a placebo (also called a dummy or ‘fake’ pill). The researchers will also want to study if sertraline improves quality of life, improve other symptoms like headaches, irritability, memory loss, and reduces stress for carers.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

01 Feb 2023 23 Jan 2025

Participants will be recruited from nine Major Trauma Centres across England and from all walks of life. Patients attending A&E with a traumatic brain injury will be given information about this study. The researchers will wait for any immediate effects of the head injury, such as memory loss, to settle. Those patients who are suitable will be invited to consent to join the study. They will be randomised, that is, they will have an equal chance of receiving sertraline or a placebo. Sertraline will be started at the lowest dose which is 50 mg and after 2 weeks increase to 100 mg. In the older patient, the dose will be increased more slowly. The researchers will then see the participants again after 6 weeks and 3, 6, 9 and 12 months. At 12 months the sertraline will be slowly reduced and stopped. The researchers will meet the participants once more at 18 months and will also seek their consent to link the research data with their GP and hospital records to see how they are getting over the next 10 years.


Patients aged 18 years and above with mild or moderate-severe TBI

Participant exclusion criteria as of 29/04/2024:1. Concurrent antidepressant medication at the British National Formulary recommended therapeutic doses for the treatment of depression2. Other causes of acquired brain injury such as stroke3. Known psychotic or bipolar disorders (except for mild cognitive impairment), known dementia (except for mild), actively suicidal, other acute or chronic neurological conditions except post-traumatic epilepsy, terminal or advanced medical illness such as end-stage kidney failure, heart failure, severe hepatic impairment4. Pregnant or planning pregnancy5. Women of childbearing potential if they are not using acceptable effective methods of contraception as defined by the Clinical Trials Facilitation Group (CTFG) (a woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle-stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. For the purpose of this document, a man is considered fertile after puberty unless permanently sterile by bilateral orchidectomy.)Female subjects must agree to one of the following during the duration of the study:5.1. Complete abstinence from intercourse of reproductive potential. Abstinence is an acceptable method of contraception only when it is in line with the subject’s preferred and usual lifestyle.5.2. Consistent and correct use of 1 of the following methods of birth control: a) intrauterine device (IUD) with a failure rate of <1% per year; b) tubal sterilization; c) vasectomy in the male partner; d) hormonal methods (oral contraceptives, injectable progesterone, implants of levonorgestrel, transdermal contraceptive patch, contraceptive vaginal ring). In the case of the Essure micro-insert system, this will need to be used in association with another method of contraception; Male subjects with female partners of childbearing potential must use condoms during the trial.6. Lactating7. Medical causes of depression such as pituitary failure8. Known allergy to sertraline9. Current hyponatraemia (if participant’s sodium is <135 mmol/L it will be discussed with the site PI or their treating physician to confirm it is safe for the patient to be enrolled)10. Taking medications contraindicated with sertraline as stated in the SmPC including concomitant treatment with irreversible monoamine oxidase inhibitors and pimozide11. Participating in another CTIMP study or participated <=30 days from consent12. Participants will be excluded if they are not able to complete self-administered questionnaires in English. (English proficiency in comatose patients will be assessed through next of kin and to the best of the ability of the clinician with the available information. Participants who come out of a coma will be reassessed for eligibility regarding English proficiency criterion. If non-proficient in English, they will be withdrawn.)

The researchers have brought together a unique team of senior doctors and researchers for this study. At each hospital a psychiatrist will lead the research supported by either a neurologist or neurosurgeon, so that patients are safely managed in terms of mental health and physical health. The researchers also have patient groups working with them, such as the charity Headway. They have already given feedback on the study which helped to improve the methods. After the study finishes, the results will be shared in medical journals, on social media and with leaders of the NHS so that the prevention of depression can be included for this group of patients.
The risks to participants in this study are comprised of the risks associated with the individual study procedures, and the study drug. Peripheral blood draws typically incur mild temporary discomfort. Rare but more serious risks include ecchymosis (bruise), thrombophlebitis (inflamed vein) and infection. This is a common procedure and the researchers will be using experienced phlebotomists in clinical settings to reduce these risks. There is a small but significant risk that some patients may become depressed during the study. This is one reason why a lead psychiatrist is included at each site. There is a small chance that some patients may become very depressed with possible suicidal thoughts. If this is detected during the study the researchers will ask for consent to inform their GP. If the patient does indeed develop severe depression with active suicidality, the researchers will contact the GP immediately to activate the usual care pathway for depression and/or refer to a local crisis team or A&E depending on the clinical judgement of the senior research psychiatrist and with the consent of the patient. This will be defined by a score of 1 or more on the PHQ-9 item 9 (suicidality question) followed by a clinical assessment by the research fellow. If the clinical status on the usual care pathway is indicated and/or the patient wishes it, the patient allocation will be unblinded. This would be reported as a serious adverse incident. Participants will be monitored carefully throughout their time in the study. They will be provided with an emergency number to call if necessary.


The study is sponsored by King's College Hospital; King's College London Hospital NHS Foundation Trust and funded by National Institute for Health and Care Research.
