The Dangers of EMDR Therapy: What You Should Know
Eye Movement Desensitization and Reprocessing (EMDR) is often promoted as a breakthrough in trauma therapy. Recognized by the WHO and APA, it's widely used to treat PTSD, anxiety, and other stress-related conditions. But while many patients report positive outcomes, others experience intense emotional or physical side effects, sometimes severe enough to interrupt treatment entirely.
Before starting EMDR, it's important to understand not only how it works, but also who may be at risk. For example, if you've recently experienced a head injury or unexplained symptoms like dizziness, nausea, or brain fog, it's crucial to rule out a neurological cause first. A quick concussion test online can help identify whether these symptoms stem from a physical issue rather than emotional trauma — a distinction that can change your entire treatment approach.
In this article, we'll explore what EMDR therapy is, why it's controversial, and the potential dangers patients should be aware of before committing to it.
EMDR (Eye Movement Desensitization and Reprocessing) is a form of psychotherapy used to treat trauma, PTSD, anxiety, and related conditions. It involves bilateral stimulation — like eye movements or tapping — to help the brain reprocess painful memories.
Unlike traditional talk therapy, EMDR doesn't require patients to recount trauma in detail. Instead, it focuses on how the body and mind respond to those memories, aiming to reduce emotional reactivity.
While many experience relief after just a few sessions, EMDR can also be intense — and may not be suitable for everyone.
While EMDR is widely considered safe, it's not without risks — especially for individuals with certain mental health conditions, physical sensitivities, or unresolved neurological issues. Understanding the dangers of EMDR therapy is essential before beginning treatment.
EMDR can trigger intense emotional responses. Patients may experience a temporary worsening of anxiety, panic, or depression as traumatic material surfaces during sessions. Some report feeling overwhelmed, detached, or emotionally raw for days afterward. If the brain is not ready to reprocess a memory, the therapy may open more than it can resolve.
Because EMDR targets subconscious memory systems, it's common for patients to experience vivid or disturbing dreams after sessions. This isn't inherently dangerous — in fact, it may indicate that reprocessing is underway — but for some, especially those prone to nightmares or insomnia, it can become a source of emotional exhaustion.
The neurological activation involved in EMDR can lead to mild physical side effects such as tension headaches, fatigue, nausea, or lightheadedness — especially during early sessions. These symptoms are usually short-term, but in certain cases, they may indicate something more serious.
For instance, if you're already experiencing dizziness, fogginess, or balance issues before starting EMDR, it's critical to rule out a neurological condition first. A simple concussion test online can help determine whether these symptoms are related to trauma or possibly an undiagnosed head injury — something that could be worsened by high-stimulation therapies like EMDR.
EMDR may reactivate traumatic memories that were previously repressed or inaccessible. For some individuals, this can be retraumatizing if they don't have the psychological tools or support system in place to process these revelations safely.
Patients with a history of dissociation or complex PTSD may be especially vulnerable to losing touch with present reality during EMDR. In rare cases, this can lead to panic attacks or full-blown flashbacks, which might require crisis intervention if the session isn't managed properly.
Like any powerful therapy, EMDR has real benefits — but they come with real risks. Knowing them in advance allows patients and clinicians to build safeguards into the process.
Despite endorsements from major institutions like the World Health Organization and the American Psychiatric Association, EMDR remains one of the most controversial trauma therapies in mental health care today. So, why is EMDR so controversial?
One of the biggest points of contention is that researchers still don't fully understand how EMDR works. While bilateral stimulation is a core component of the process, some studies suggest that it may not be essential — raising questions about whether the eye movements themselves add value beyond standard exposure therapy.
EMDR is sometimes marketed as a quick fix for trauma — a few sessions and you're 'cured.' In reality, its effectiveness depends on the patient, the therapist's skill, and the complexity of the trauma. This gap between public perception and clinical reality has created skepticism in the medical community.
Not all EMDR therapists are created equal. Some complete only a weekend workshop, while others undergo months of supervised training. This wide range of preparation means that patient outcomes can vary dramatically, leading some to question the reliability of the method across practitioners.
The emotional risks of EMDR — including retraumatization, dissociation, and destabilization — are rarely discussed in promotional materials. Critics argue that patients are not always properly screened or prepared for the intensity of the sessions, especially when underlying conditions (like TBI or psychosis risk) are overlooked.
In short, EMDR is effective for many, but controversial because of its inconsistent outcomes, unresolved scientific questions, and lack of safeguards in some therapeutic settings.
Although EMDR therapy has helped many people recover from trauma, it's not suitable for everyone. For individuals with certain medical or psychological conditions, the risks may outweigh the benefits — especially if no screening or support is in place.
People with certain conditions should proceed carefully or consult a specialist first: Psychosis or dissociative disorders: EMDR may trigger disorientation or flashbacks without proper support.

Drugs affecting memory, sleep, or emotional regulation may interfere with EMDR's effects. Chronic migraines or epilepsy: Sensory triggers like light or sound may worsen symptoms.
Sensory triggers like light or sound may worsen symptoms. No support system: EMDR can surface intense emotions. Having emotional backup is essential.
Being cautious means being smart — not avoiding healing, but preparing for it safely.
To reduce risks, EMDR should always be guided by a certified, experienced therapist. Before starting, patients should: Undergo a full mental and physical health screening
Discuss any history of neurological symptoms or dissociation
Create a coping plan for intense emotions between sessions
Ensure they have post-session support (friend, therapist, or helpline)
Consider a concussion test online if dizziness, fogginess, or memory issues are present
When done correctly, EMDR can be powerful — but safety should always come first.
EMDR therapy offers real hope for people struggling with trauma, anxiety, and emotional pain. But like any intense treatment, it comes with risks that deserve serious consideration — especially for individuals with underlying neurological or psychological conditions.
If you're considering EMDR, take the time to learn how it works, understand its limitations, and screen for any red flags beforehand. That includes addressing physical symptoms that may not be emotional in origin. Tools like a quickconcussion test online can help rule out hidden issues before you begin.
In the right hands and with the right preparation, EMDR can be transformative. Just make sure you're fully informed — and fully supported — before you begin.

Alcohol linked to increased risk of pancreatic cancer: Study
Alcoholic beverages, particularly beer and spirits, may increase the risk of developing pancreatic cancer, according to a new study led by the UN World Health Organization. The research, which pooled data from nearly 2.5 million people across Asia, Australia, Europe and North America, revealed a 'modest but significant' link between alcohol consumption and pancreatic cancer risk, regardless of sex or smoking status. 'Alcohol consumption is a known carcinogen, but until now, the evidence linking it specifically to pancreatic cancer has been considered inconclusive,' said Pietro Ferrari, senior author of the study and head of the nutrition and metabolism branch at the World Health Organization International Agency for Research on Cancer. The study revealed that each additional 10 grams of alcohol consumed per day was associated with a three percent increase in pancreatic cancer risk. Additionally, women consuming 15-30 grams of alcohol daily, which equates to about one to two drinks, had a 12 percent higher risk. Men drinking 30-60 grams daily had a 15 percent increased risk, increasing to 36 percent for those consuming more than 60 grams. The study confirmed alcohol as an 'independent risk factor,' even after accounting for smoking. Ferrari emphasized that 'alcohol is often consumed in combination with tobacco,' but the elevated risk persists among non-smokers. Pancreatic cancer, a disease that impacts digestive enzyme production and blood sugar regulation, remains one of the deadliest cancers due to late-stage diagnoses. Although it ranks 12th in global cancer incidence, it accounts for 5 percent of all cancer-related deaths, according to the WHO. Copyright 2025 Nexstar Media, Inc. All rights reserved.

HIV Prevention Vaginal Ring Recommended for 16-Year-Olds
The European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) has recommended an extension of indication for dapivirine vaginal ring 25 mg to include its use in women from 16 years of age. The EMA said there had been some uncertainties about the risk for resistance and the benefits in younger women, which needed to be addressed. Upon further study, the ring was shown to be moderately effective at lowering the risk for HIV-1 infection following vaginal intercourse, with its side effects considered manageable. As such, the EMA decided that its benefits outweigh the risks in women who are not using oral pre-exposure prophylaxis (PrEP). The dapivirine ring was originally approved in July 2020 to reduce the risk for HIV-1 infection in women 18 years and older through vaginal intercourse, when taking PrEP medicines by mouth was not feasible. It is the first long-acting technology approved for HIV prevention in women and is intended for use outside the EU. The device was submitted under a regulatory procedure, EU- Medicines for all (EU-M4All) that enables the EMA, in collaboration with the World Health Organization (WHO), to provide scientific opinions on high priority human medicines that are intended for markets outside the EU. The process allows the European agency to support global regulatory capacity building and contributes to the protection and promotion of public health beyond the EU. Its overall aim is to facilitate access to essential medicines in low- and middle-income countries that are intended to prevent or treat diseases of major public health interest. The flexible silicone ring is inserted in the vagina for a period of 28 days, after which it should be replaced by a new one. It works by slowly releasing dapivirine over the course of a month, which blocks the ability of HIV to make copies of itself inside healthy cells. It can be inserted and removed by the user. A study conducted in almost 2000 women in sub-Saharan Africa showed that dapirivine vaginal ring 25 mg lowered the chances of being infected with HIV by more than one third over the course of 24 months compared with the placebo group. It was first developed by the International Partnership for Microbicides and since acquired by the Population Council in 2022. It was first approved in 2021 by the Medicines Control Authority of Zimbabwe and has since been approved in several additional African countries. The ring has been on the WHO's prequalification list of medicines since November 2020 following positive scientific opinion from the EMA. The WHO has said it is intended to reduce the risk of acquiring HIV during vaginal sex for women who are at substantial HIV risk as a complementary prevention approach in addition to other safer-sex practices. The CHMP's opinion to extend the indication for this medicine to include its use in women from 16 years of age expands the HIV prevention choice beyond condoms and oral PrEP and could be an important tool to protect younger women from becoming HIV-positive.

Portugal's Prisons: Too Many Patients, Too Few Psychiatrists
The number of healthcare professionals working in Portuguese prisons is insufficient to provide adequate care — particularly for individuals with psychiatric conditions — according to recent findings that underscore a growing public health concern within the country's correctional system. Key barriers include overcrowded prison facilities and a shortage of medical staff, which hinder incarcerated individuals from accessing care equivalent to that provided through Portugal's public healthcare system, the Serviço Nacional de Saúde. Mental health care is particularly affected. A 2023 report by the World Health Organization (WHO) on healthcare in European prisons identified mental health access as the most urgent concern. The report estimated that 32.8% of people in custody across the European region have a mental disorder — more than twice the 13.1% prevalence found in the general population. Portugal did not submit detailed data on the mental health of its incarcerated population for the WHO report. Among the 36 countries surveyed, Portugal was one of 16 that did not respond to that portion of the questionnaire. However, a separate report from the Portuguese government titled Health Plan in the Context of Deprivation of Liberty provided a more comprehensive overview of healthcare services in the nation's prisons, along with proposals for improvement. Developed by a multidisciplinary expert group, the report cited data from the World Mental Health Survey showing that 22.3% of the Portuguese population experiences psychiatric disorders — above the European average of 14.2%. It also suggested that prevalence may be even higher within prison populations. 'This population has significantly higher rates of mental illness and psychiatric disorders compared to the general population, as multiple studies have shown — and for a variety of reasons,' said Susana Pinto Almeida, MD, psychiatrist at São João de Deus Prison Hospital in Caxias, Portugal. Almeida, a subspecialist in forensic psychiatry, emphasized that incarceration itself is a major risk factor for mental illness. The structure and constraints of the prison environment can worsen existing psychiatric conditions or precipitate new ones. She also highlighted two critical moments for mental health deterioration: entry into the prison system and the delivery of a court sentence. Both are associated with an increased risk for suicide. Suicide remains the leading cause of death in European prisons, according to the WHO. In Portugal, the inmate suicide rate is also higher than that of the general population. In 2022, 14 out of 64 deaths recorded in Portuguese prisons (21.9%) were due to suicide — corresponding to a crude mortality rate of 117 per 100,000 inmates. By contrast, the suicide rate in the general Portuguese population was 8.9 per 100,000 in 2021. Preventive Programs and Ongoing Gaps Portugal has implemented several initiatives aimed at improving mental health care in prisons. One key intervention occurs at the time of entry into the correctional system — a moment widely recognized as critical for identifying individuals at risk. Under current legislation, all newly admitted inmates must undergo a comprehensive health assessment. This initial screening is designed to detect psychiatric disorders, suicide risk factors, withdrawal syndromes, signs of physical or sexual abuse, communicable diseases, and chronic conditions. The assessment must be conducted by a nurse within 24 hours of admission and by a physician within 72 hours. If suicide risk indicators are identified, the individual is referred for urgent evaluation by a psychiatrist. In addition, Portugal has established the Integrated Suicide Prevention Program, which includes a two-step screening process: an initial checklist completed by a correctional officer to identify warning signs, followed by a questionnaire administered by the facility's educational staff. Despite these protocols, the government's own reporting acknowledges that implementation may be inconsistent. 'According to the European Prison Observatory, suicide risk assessments during intake — and the associated prevention plans — are often only activated in response to public concern. In practice, statutory requirements are frequently overlooked,' said Almeida. Staff Shortages and Operational Barriers Workforce shortages remain a significant obstacle to providing adequate healthcare in Portuguese prisons. According to 2020 data from both the WHO report and the Portuguese government's prison health improvement plan, 382 healthcare professionals — including external contractors — were working across the national correctional system. Nurses made up the majority (318), followed by physicians (33). Despite Portugal having 49 correctional facilities, only 17 psychiatrists were reported to be working in prisons at the time — equating to a ratio of 1.7 psychiatrists per 1000 inmates. While this is higher than the ratio in the general population (0.7 per 1000), it is still considered insufficient to meet the complex mental health needs of the incarcerated population. A 2019 report by the European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment also deemed the number of healthcare professionals in Portuguese prisons inadequate to ensure proper medical care. The report highlighted not only staffing shortages but also high turnover rates among prison healthcare workers. Further, the Portuguese government's own data point to a substantial gap between projected and actual staffing levels. In 2021, for example, only 23 of the 64 planned physician positions were filled. In addition to clinical staff, inmates also interact with senior rehabilitation technicians — nonclinical professionals who work closely with incarcerated individuals and are trained to recognize signs of mental health issues. Almeida emphasized that the limited number of psychiatrists significantly impedes early detection and proper treatment of severe psychiatric disorders such as schizophrenia and bipolar disorder. 'Most inmates are young adults under the age of 35. Among men, who make up the majority of the prison population, serious mental illnesses often emerge during early adulthood,' she said. 'These conditions are frequently underdiagnosed or misdiagnosed in this setting.' While Portuguese legislation has introduced important reforms to improve prison mental health care and sets out standards for appropriate treatment, Almeida believes these guidelines have yet to be fully implemented. She called for increased public attention to both the mental health needs of incarcerated individuals and the working conditions of the professionals who care for them. 'Prison psychiatry must be treated with the dignity and respect it deserves,' she said. 'It's painful to confront a reality shaped by indifference toward an ultra-vulnerable population,' she added. 'If living with a mental illness is already a vulnerability, then individuals who are both mentally ill and incarcerated face compounded hardship — they've lost their mental clarity and their freedom. It's a double loss.' Medscape's Portuguese edition reached out to Portugal's Directorate-General for Reintegration and Prison Services, the agency under the Ministry of Justice responsible for prison healthcare, but did not receive updated data or comment.
