Acutely Ill Mental Health Patients Held in Prisons as Central Mental Hospital Reaches Capacity
A deepening crisis in Ireland's forensic mental health system has led to acutely psychotic and mentally ill patients being held in prisons because there are no beds available at the Central Mental Hospital in Dundrum — a situation that mental health advocates have described as a fundamental failure of the State's duty of care to some of its most vulnerable citizens, and one that has been worsening steadily throughout 2026.
Background
The Central Mental Hospital (CMH) in Dundrum, south Dublin, is Ireland's national forensic psychiatric facility — the institution responsible for the assessment and treatment of people who have come into contact with the criminal justice system and who have significant mental health needs. The CMH provides inpatient care for people who have been found not guilty by reason of insanity, those who have been transferred from prison for psychiatric treatment, and those who are on remand and require forensic psychiatric assessment.
The CMH has been operating at or near capacity for several years, a situation that reflects both the growing demand for forensic psychiatric services and the chronic underinvestment in mental health infrastructure that has characterised Irish health policy for decades. The 2006 mental health policy document A Vision for Change set out a comprehensive framework for the development of community-based mental health services and the reduction of reliance on institutional care, but its implementation has been slow and incomplete, leaving the CMH as the primary resource for a population with complex and acute needs.
The problem of mentally ill people being held in prisons is not new in Ireland, but the scale of the crisis has reached a new level of severity in 2026. RTÉ Investigates reported in February that 38 people were on a waiting list for a place at the CMH while being detained in prison — a figure that represents a significant increase from previous years and that has prompted urgent calls for action from mental health advocates, legal professionals, and opposition politicians.
Key Developments
The crisis has been worsened by the suspension of "therapeutic bail" — a legal mechanism that previously allowed courts to divert some individuals with mental health needs away from custody and into community-based psychiatric care as a condition of bail. The suspension of this mechanism, which occurred as a result of legal and administrative challenges, has removed an important safety valve from the system, leaving courts with fewer options when dealing with defendants who have significant mental health needs but who do not meet the threshold for immediate admission to the CMH.
The Irish Penal Reform Trust and the Mental Health Commission have both raised serious concerns about the conditions in which mentally ill prisoners are being held. Prison environments are fundamentally unsuited to the treatment of acute mental illness — they lack the therapeutic resources, the clinical expertise, and the physical environment needed to provide appropriate care. The risk of deterioration in the mental health of individuals held in prison while awaiting a CMH place is significant, and there have been reports of individuals experiencing acute psychiatric crises in prison settings without access to appropriate clinical support.
The HSE has acknowledged the problem and has indicated that it is working to increase the capacity of the CMH and to develop alternative forensic psychiatric facilities. However, the timeline for these developments is measured in years rather than months, and in the interim, the crisis is continuing to worsen. The Department of Justice has been in discussions with the Department of Health about interim measures to address the most acute cases, but no comprehensive solution has yet been announced.
Why It Matters
The detention of acutely mentally ill people in prisons is a human rights issue as well as a health policy failure. The European Convention on Human Rights, to which Ireland is a signatory, requires that people deprived of their liberty receive appropriate medical care, and the detention of acutely psychotic individuals in prison environments without access to psychiatric treatment raises serious questions about Ireland's compliance with this obligation. The Mental Health Commission, which has statutory responsibility for monitoring the quality of mental health services in Ireland, has the power to investigate and report on conditions in facilities where mentally ill people are detained, and it is expected to publish a report on the prison situation before the end of the year.
The crisis also reflects a broader failure of mental health policy in Ireland. Despite the commitments made in A Vision for Change and its successor document Sharing the Vision, published in 2020, the development of community-based mental health services has been too slow to prevent the accumulation of unmet need that is now manifesting in the CMH waiting list crisis. The investment in mental health services, while increasing in recent years, remains below the levels recommended by the World Health Organisation and below the levels seen in comparable European countries.
Local Impact
The impact of the mental health crisis is felt across the country, but it is particularly acute in Dublin, where the CMH is located and where the concentration of the prison population means that the waiting list problem is most visible. Mountjoy Prison, the Dóchas Centre, and Cloverhill Remand Prison are among the facilities where mentally ill prisoners are being held while awaiting CMH places. The Irish Prison Service has been working to improve the mental health supports available within prisons, including the expansion of in-reach psychiatric services, but these measures are widely regarded as inadequate to address the scale of the problem. In the community, the shortage of acute psychiatric beds — not just at the CMH but across the general adult mental health system — means that people in crisis are often unable to access inpatient care when they need it, increasing the risk of contact with the criminal justice system.
What's Next
The HSE is expected to publish a plan for the expansion of forensic psychiatric capacity before the end of 2026, including proposals for new facilities that could reduce the pressure on the CMH. The Mental Health Commission's report on conditions in prisons is expected in the autumn. The Oireachtas Joint Committee on Mental Health has scheduled hearings on the CMH waiting list crisis for July, at which the HSE, the Irish Prison Service, and advocacy groups will be invited to give evidence. The Government has indicated that it is committed to addressing the crisis, but has not yet set a specific timeline for resolving the waiting list problem.
